Automatic Orderly Shutdown of Emulated VAX/VMS System in SIMH

by nf6x＠nf6x.net

I'm not sure if the HECnet list is the best place to ask this, but hopefully it's not too far off topic. Let's say that I want to run a full-time SIMH emulation of a VAX running VMS (because I do). This would be my full-time DECnet presence on my local network, my primary means of moving things between my DECnet-speaking computers and my modern machines, and my full-time HECnet presence if I ever find a good way to have persistent internet access at my rural home. The SIMH emulation would be hosted on a Linux server. It's easy enough to set up the host server to automatically launch a SIMH emulation at boot time, but I don't know yet how to deal with automatically and cleanly shutting down the emulation when the host server needs to shut down. In particular, I'd want to somehow trigger an orderly VMS shutdown when the host server needs to perform an unattended shutdown, such as when the UPS signals a power failure. If there's a way to checkpoint the entire emulation and then restore it later, that might also be a good option, as long as I can prevent corrupting the emulated system's filesystems by suddenly yanking the virtual power plug. Is there any prior art for setting up an unattended SIMH-based VAX/VMS emulation like this? -- Mark J. Blair <nf6x at nf6x.net> http://www.nf6x.net/

RVDSXL

by rok.vidmar＠gmail.com

Can somebory try to login via Hecnet to RVDSXL (3.47) please and report the result? There is no GUEST account on it, as far as I know. The machine is responding to ping, but telnet and SSH time out. -- Regards, Rok

help finding DECUS stuff

by mcguire＠neurotica.com

Hi folks. I've found something that I'm looking for listed in the SIGTAPES.SUM file in the rsx freeware CD v2, but I can't find the actual software anywhere. It's from the European 1984 RSX SIG Tape, Amsterdam. Maybe I'm being dense but I can't find that stuff anywhere. The specific software I'm looking for is called CCDRV; if you search for that in SIGTAPES.SUM it's listed there. Can anyone help? Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

Time for a new release announcement of TCP/IP for RSX-11M-PLUS. I usually try to avoid spamming lists with release announcements, and the previous announcement was only a month ago, so I apologize in advance for the noise. However, I have a really good reason for this announcement. In the last few days I identified a bug within RSX, that has been latent for many years, but which gets activated when TCP/IP is installed. Because of this, I've cut a new distribution of BQTCP, which now also includes some patches to RSX, which I really implore everyone to install. Highlights: - Stability and reliability improvements in RSX. - Improved stability of Multinet. - Improved stability of MAILD. Detailed information on things that have been done since the last release: RSX: - The MCR REMOVE command have an interaction with the IP: device driver, which have a bug. Traditionally, the IP: device driver was for the IP11 device, which I doubt anyone have used in many years, so this bug have probably been around a long time without detection. The result of it is that low core and pool will get corrupted when giving the REMOVE command, and IP: exists. BQTCP now includes an optional "patch RSX" section in IPGEN, which will install a new version of MCR on the system. This is only needed to be run once, as the patching is installing new tasks, and changing the bootable image to use these new tasks, which is a more permanent change. Along with the fix for the memory corruption issues, the new version of MCR will also fix a few other issues that people might or might not have noticed. There is some more details in the BQTCP documentation. Multinet: - Some transmit errors should restart the link, but this was not done. Fixed now. MAILD: - Added paging to mail reader. - Improved remote node system type detection for DECnet. - Improved the memory layout of MAILD, to avoid some crash situation. As usual, the distribution is available from: ftp://mim.update.uu.se/bqtcp.dsk ftp://mim.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The documentation is also available through ftp on Mim, or also at http://mim.update.uu.se/tcpipdoc The firewall for Mim have now been removed, so no need for the alternate ports, but Mim is still listening to the alternate ports as well. ftp: 10021 telnet: 10023 Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Multinet IPv6 DNS lookup Induced Delay

by dwe-6006＠philtest.org

I have seen this elsewhere but I see no reference to a fix to the problem on Multinet. I have a Multinet SSHD agent running and when I attempt to do a connection the connection does succeed but it can take 90 seconds. I put a Sniffer on the line and the SSHD agent is attempting to do reverse DNS lookup on the incoming address. This is normal, but it is doing 6 IPv6 resolution attempts (3 to each of the 2 DNS servers) before it makes the first IPv4 request. I do not have IPv6 configured on the interface (or any interface) and I need to find a way to suppress all IPv6 DNS queries( PTR or AAAA) is here a magic incantation or a logical name that makes this happen?

Connections?

by bqt＠softjar.se

Guys. I figure I should try to get a more formalized handling of connections to HECnet. With my bridge, it's mostly just people connecting to me, but this is not a solution that scales very well, so in general I now try to discourage people from this option. When possible, I prefer to move people away from it. Multinet on the other hand scales well. And is possible to use directly both in VMS and RSX. However, it is silly and inefficient if all multinet links are to go to me. So I'm thinking about identifying a few people/places elsewhere in the world, which can be used for connections where it makes more sense for a somewhat closer point of connection. So, I would go on dealing with Europe. Might at some point be that we'd like a second point in the south of Europe, but that is not a high priority right now. However, for the US, it would be nice if we could identify a location on each coast, which have a capable system, and normally is always online, and which have a good bandwidth, and would be willing to setup connections to new machines that want to come online. So, are there any takers? I'll continue to be the first point of contact when people come asking, but I'd be happy if I could redirect them to the appropriate person once we have figured out a few basic details. And then these two persons can work on establishing the actual link.

Shameless plug or something here: I have a program called anftunnel which as the name suggests initially was used to handle ANF-10 packets. It has grown a bit from that, and can do other things as well now. Amongst what it can do is: * Set up a tunnel between two machines, with optional crypto and auth. The passive (listening) end needs a static address, the other don't. * Talk to an ethernet interface (via libpcap) and tunnel ethernet frames. * Terminate a (virtual) sync line and tunnel the frames. Handle TCP and UDP encapsulated DDCMP lines of the SIMH variety. * Terminate a MULTINET DECnet-over-IP link. (untested, but given how simple the encapsulation is...) * For ANF-10, it can connect an ethernet to a sync line. This requires slightly molesting the packets involved. It should be possible to use this to tunnel DECnet/Multinet between two nodes and keep the Multinet part local to each host. A slight perversion would be to connect a Multinet link to a DDCMP one...

RSX software...

by bqt＠softjar.se

Someone asked a while ago about DECUS software for RSX. I've now set things up on Mim. So pretty much all DECUS software can be found at MIM::DECUS: While I was at it I also decided that I might as well make some of the DEC software available as well to people on HECnet. So, there is also MIM::KITS:, which have various layered products I have tape images for. I would actually suggest people fetch things through TCP/IP and not DECnet when possible, since TCP/IP is both more efficient, and also preserves meta information better on transferred files. (But both ways will work.) So, have fun installing all kind of stuff. Also, for most things I also have manuals at http://mim.update.uu.se/manuals I have some more manuals that I have not scanned yet, and I know that some of the manuals in there are not really well scanned, and might lack a page or two. Let me know if you have any issues, and I'll try to help.

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

Time for a new release announcement of TCP/IP for RSX-11M-PLUS. This release contains a lot of fixes and improvements in many areas. There are a couple of very serious bugs in TCP that is fixed in this release which is why I really encourage people to upgrade. (They do not happen often, but if they happen, they have a high chance of crashing the system.) Highlights: - Stability and reliability improvements in TCP. - Improved logic for TCP probing, keepalive and retransmits. Magica (a real PDP-11/70) and Mim (an emulated PDP-11/74) have been serving traffic for several weeks without any issues, and I think I have finally found and fixed a very obscure problem that occasionally could crash the system. (And both of these machines are more or less fully exposed to the internet, so they see a *lot* of connections and random attempts to compromise them all the time.) Detailed information on things that have been done since the last release: TCP: - Correct TCP reception. It could stop the retransmit timer even if there was still data outstanding under some circumstances. - Bugfix in data resend in TCP. Under some circumstances the retransmit timer stopped even though there was data to send. - Improved TCP retransmit timers to better handle probing and keepalive. - Improved TCP keepalive timer handling. - Improved TCP timeout handling for closing sockets. - Improved TCP retransmit timer restart logic in received TCP ACK processing. - General rework of TCP retransmit logic. - Bugfix. In TCP TimeWait state, received FIN packets did not result in an RST packet. - Changed TCP FinwWait2 to use keepalive timer to probe connections. - Improvement to TCP reception to dedup received packets also for packets that are pending. - Bugfix in TCP packet sending. If we ran out of IP POOL, memory got corrupted. - Improved handling of TCP receive window if TCP receive size is shrunk. - Add probing of socket during closing stages, since we have no other way to tell if the remote end is still around. - Change how TCP decides if it should probe a connection. - Bugfix in TCP. If a socket had no window but outstanding data, and was closed, and other end never opened up a window (for example if the remote end is gone), then the socket would get stuck in Fin-Wait-1. - Changed TC driver so that user ASTs are generated immediately if there is data to be read and the AST address is changed. - Improve TCP options processing. Some badly formatted tcp options packets could crash the system. - Improved TCP handling of ICMP error packets. UDP: - Bugfix in UDP. If several error packets were received for a socket, several ASTs were queued, but only one error is saved, meaning the additional ASTs could make code try to read several times, when all except the first would not have anything to actually read. TELNET/TELNETD: - Improved abort handling in telnet client. - Changed TELNETD do do spoof notifications in a simpler way. - Rewritten TELNETD to handle fast input without loosing characters. - Fix mapping error under special circumstances in telnetd, which could corrupt the system. - Added more IAC options processing in telnet and telnetd. DNS: - Improved name resolution handling if no UDP available. - Improve resolver domain I/O error handling. RWHOD: - Added handling of no UDP available in RWHOD. MAILD: - Improve MAILD handling of DECnet connections. - Improved privilege handling in MAILD. - Improved maild unread message function. - Added manual holding of mails. General: - Improved ability to stop protocols from IFCONFIG. As usual, the distribution is available from: ftp://mim.update.uu.se/bqtcp.dsk ftp://mim.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The documentation is also available through ftp on Mim, or also at http://mim.update.uu.se/tcpipdoc The firewall for Mim have now been removed, so no need for the alternate ports, but Mim is still listening to the alternate ports as well. ftp: 10021 telnet: 10023 Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Strange unit of time

by ian＠platinum.net

Excuse the noise, but I?ve got a fragmented recollection of a strange unit of time, and my faulty memory seems to equate this with VAX and/or VMS. My google-fu has failed me (or confirmed that this is some sort of fake memory) however I thought I?d run it past the experts in here. Does anyone know of anything strange about the unit of time, or possibly the epoch, or something else associated with time measurement (or the TOY clock or basically anything to do with time) in the DEC world? Sorry for the vagueness of the question, but hopefully someone can help :) Ian

Asymmetric connectivity in a cluster

by dwe-6006＠philtest.org

I'm not sure that asymmetric is the correct description but I can't think of a better term. I am using SIMH and I have a two node cluster (with a quorum disk) the two nodes have a common system disk. The two nodes are RODNEL (1.1) booting from SYS0 and ADV2 (1.3) booting from SYS2. Both are running DECnet Plus both are running Multinet for the IP stack. At one time there was also a node (never actually a member of the cluster called HCBVAX (1.2) it booted from SYS1 but it no longer exists. The nodes are connected over an Ethernet and the MAC addresses are the ones that I would expect AA-00-04-00-01-04 (1.1) and AA-00-04-00-03-04 (1.3) HCBVAX was AA-00-04-00-02-04 (1.2) I can login to RODNEL and "set host adv2" with no problem, I can login to ADV2 and "set host rondel" with no problem. On each of the nodes I can "show cluster" and I see what I expect to see with no errors. While logged in to RODNEL the command "moni cluster" works fine. While logged in to ADV2 the wheels seem to fall off the bus - "show cluster" is fine but "moni cluster" isn't Any help would be appreciated. This is the information that I have gathered so far (I am not happy with the forwarding address in the error message from "moni proc" on ADV2 which seems to arise from RODNEL --Dave View of Cluster from system ID 1027 node: ADV2 22-APR-2018 22:24:50 +-----------------------------+ | SYSTEMS | MEMBERS | +-------------------+---------| | NODE | SOFTWARE | STATUS | +--------+----------+---------| | ADV2 | VMS V7.3 | MEMBER | | RODNEL | VMS V7.3 | MEMBER | +-----------------------------+ ^Z $ $ moni cluster %MONITOR-I-ESTABCON, establishing connection to remote node(s)... %%%%%%%%%%% OPCOM 22-APR-2018 22:24:56.75 %%%%%%%%%%% Message from user SYSTEM on RODNEL Event: Address Unreachable PDU Discard from: Node LOCAL:.RODNEL Routing, at: 2018-04-22-23:24:56.740-04:00Iinf Discard Reason=Destination Addrs Unknown, Source Address=49::00-01:AA-00-04-00-03-04:21, Forwarding Address=49::00-01:AA-00-04-00-02-04:21 eventUid FC95D640-467B-11E8-99E1-AA0004000104 entityUid 5683CC80-467B-11E8-8004-AA0004000104 streamUid 5A113900-467B-11E8-8004-AA0004000104 Still on ADV2 - NCP is odd as well: $ mcr ncp NCP>sho exec char Node Volatile Characteristics as of 22-APR-2018 22:31:17 Executor node = 1.3 (ADV2) Identification = DECnet-OSI for OpenVMS Management version = V4.0.0 Incoming timer = 0 Outgoing timer = 0 NSP version = V4.1.0 Maximum links = 0 Delay factor = 0 Delay weight = 0 Inactivity timer = 0 Retransmit factor = 0 Routing version = V2.0.0 Type = nonrouting IV Routing timer = 0 Subaddresses = 0 Broadcast routing timer = 0 Maximum address = 0 Maximum circuits = 0 Maximum cost = 0 Maximum hops = 0 Maximum visits = 0 Maximum area = 0 Max broadcast nonrouters = 0 Max broadcast routers = 0 Maximum path splits = 0 Area maximum cost = 0 Area maximum hops = 0 Maximum buffers = 0 Segment buffer size = 0 Buffer size = 0 Pipeline quota = 0 Alias maximum links = 0 Path split policy = Normal Maximum Declared Objects = 0 NCP>show know nodes Known Node Volatile Summary as of 22-APR-2018 22:31:29 Executor node = 1.3 (ADV2) State = on Identification = DECnet-OSI for OpenVMS NCP>def node rodnel Node address (1.1-63.1023): 1.1 Node name (1-6 characters): rodnel NCP>set node rodnel all %NCP-W-UNRCMP, Unrecognized component NCP>set node rodnel Node address (1.1-63.1023): 1.1 Node name (1-6 characters): rodnel %NCP-W-UNRCMP, Unrecognized component , Node NCP>exit Whereas RODNEL seems happier: NCP>sho exec char Node Volatile Characteristics as of 22-APR-2018 20:15:29 Executor node = 1.1 (RODNEL) Identification = DECnet-OSI for OpenVMS Management version = V4.0.0 Incoming timer = 0 Outgoing timer = 0 NSP version = V4.1.0 Maximum links = 0 Delay factor = 0 Delay weight = 0 Inactivity timer = 0 Retransmit factor = 0 Routing version = V2.0.0 Type = nonrouting IV Routing timer = 0 Subaddresses = 0 Broadcast routing timer = 0 Maximum address = 0 Maximum circuits = 0 Maximum cost = 0 Maximum hops = 0 Maximum visits = 0 Maximum area = 0 Max broadcast nonrouters = 0 Max broadcast routers = 0 Maximum path splits = 0 Area maximum cost = 0 Area maximum hops = 0 Maximum buffers = 0 Segment buffer size = 0 Buffer size = 0 Pipeline quota = 0 Alias maximum links = 0 Path split policy = Normal Maximum Declared Objects = 0 NCP>sho kno node Known Node Volatile Summary as of 22-APR-2018 20:15:37 Executor node = 1.1 (RODNEL) State = on Identification = DECnet-OSI for OpenVMS Node State Active Delay Circuit Next node Links 1.3 (ADV2) 1.1 (RODNEL) NCP>sho node adv2 char Node Volatile Characteristics as of 22-APR-2018 20:16:02 Remote node = 1.3 (ADV2) Service password = 0000000000000000

Handful of points: * the idling is done by modifying the idle loop in the guest operating system to interact with the KLH10 idler device, not by identifying the idle loop like SIMH does. * until the OS is up and running, there is no idling. In other words, while at the BOOT> prompt there will be a loop consuming 100% CPU waiting for terminal input. This is normal, and it has always been that way. * if you have had the same TOPS20 system running, with idling, earlier everything points at your host os (ubuntu) no longer cooperating with KLH10. I myself run (mostly) FreeBSD, and I have never had problems with idling the TOPSxx systems. * for TOPS10, there are a couple of more things to consider, one of them is that the idler device by default is at device code 700, which can't be accessed from the mode the -10 idle code runs in. Using 740 works. I would look for what has changed in your host os (ubuntu) regarding system timers and such. Your setup *should* work. > Thanks, > Mark --Johnny

(They do not happen often, but if they happen, they have a high chance of crashing the system.) Highlights: - Stability and reliability improvements in TCP. - Improved HTTPD - Improved MAILD Magica.Update.UU.SE, which is a real PDP-11/70, have now run with the latest release for over 3 weeks without any issues, so I think it's safe to say that this product is now very stable. Mim.Update.UU.SE (an emulated 11/74) have in the same time served over 7Gb of data over FTP, HTTP and other lower volume channels. (And both of these machines are more or less fully exposed to the internet, so they see a *lot* of connections and random attempts to compromise them all the time.) Detailed information on things that have been done since the last release: TCP: - Improved handling of received TCP push packets. - Improved TCP ACK handling under lost packet recovery. - Improved TCP window update handling. - Bugfix for the condition that a socket was closed while there was outstanding sends and the remaining window was 0 and the transmission was not ACKed. This would cause the socket to get stuck in a pending state. - Improved TCP write handling. The second IOSB word was previously not set to reflect how much data was written. - Added new TCP option for sockets to optionally return available data at read if push was set. - Bugfix in TCP. An internal data structure was sometimes modified when it should not be, which could cause a system crash under rare circumstances. HTTPD: - Improved error handling for CGI pages. - Improved subprocess handling for CGI module. MAILD: - Improved MAILD to handle broken Linux MAIL11 server. - Improved MAILD error handling. - Bugfix in MAIL. When composing mails, the temporary file is now created under SYS$LOGIN. - Added timeouts for various parts of MAIL11 processing. Libraries: - Improved subprocess handling in BASIC+2 library. - Updated F77 library and documentation. Multinet: - Improved performance.

KLH10 not idling host CPU

by phiber＠phiber.com

I'm posting this here in the hopes that there are other KLH10 emulator users on HECnet. I've been using KLH10 with the tap patches for years and years, and idling has always worked fine. At some point over the recent couple of years, idling stopped working for me on linux (I run ubuntu 16.04.4 LTS with latest updates as of yesterday, on a 64-bit intel machine). My CPU is stuck at 100% utilization, without even starting an emulated OS (I run TOPS-20). In fact, as soon as I type "GO" in KLH10 and before doing anything else, the CPU immediately shoots to 100%. Is anyone else seeing this? In older versions of ubuntu/linux this didn't happen. Thanks, Mark

Public Services over DECnet

by fsword007＠gmail.com

Yes I am interested in that. Let me know when done. Also you can send scanned docs to bitsavers. I put each package funetnje and hujinje into git together and uploaded it into my github account. For decent for Linux, I converted CVS repo into git repo and uploaded it into my github too. So you can now apply fixes to that repo. If you find JNet 2.x software, please let me know. There is programming guide doc in JNet package through 3.2. It was removed on 3.3 or above. No they are not in funet and can?t find them through google so far. Does anyone have JNet for Alpha? I have only JNet 3.5 to 3.7 for VAX.

by nf6x＠nf6x.net

I come from a mostly-UNIX, mostly-TCP/IP background. I don't understand DECnet well yet, but I want to learn more! Much of my interest in joining HECnet and playing around is because I largely skipped over DECnet in its original airing, and now it seems like a weird foreign land that I feel an irrational need to grok in fullness. What are/were the conventions for providing public services over DECnet Phase IV networks, to remote users without their own local user accounts? I.e., let's say that I had a node on a large DECnet-only network back in the before time, and I wanted to share a file repository in a manner comparable to anonymous FTP on a TCP/IP network. How would I have done that? Were there conventions for doing that sort of thing back then, or was that a foreign concept on large DECnet networks at the time? Were there any examples of BBS-like servers living on DECnet networks? Online multi-player games such as MUDs? Early DECnet-based examples of "log into the coffee pot to see if the brew is fresh"? DECnet-based analogs to Archie for discovering stuff? DECnet-based USENET-like communities? I don't know if any of these concepts even made sense in the DECnet world at the time. In addition to only understanding the networks of the 80s from a UNIX-centric, TCP/IP-centric worldview, I'm also having a hard time un-thinking the newer concepts I'm used to after so many years of steeping in a broth of HTTP and social media. I have somewhat conflicting urges to both learn how to think like a 1980s DECnet user, and to retcon modern concepts into an alternate reality where TCP/IP never took off. -- Mark J.

DECnet for Linux

by e.olofsen＠xs4all.nl

For those interested in running the updated DECnet kernel module under Ubuntu rather than Slackware, I gave it a go by updating my machine running 16.04 following the steps at: >From https://www.maketecheasier.com/build-custom-kernel-ubuntu/ And it was quite easy indeed. [But have plenty of free disk space, say >20 GB. If the make fails, and you have to start over, it does a 'clean' first. So even when doing make...] Of course, after the step to have the kernel source ready, for example in 'kernelbuild', cd to 'kernelbuild/net' and unzip the dflkm.zip file, which may be found at RULLFS::

Uptime

by bygg＠cafax.se

One of my nodes fell off Hecnet (actually a while ago). I finally got around to reboot it in order to get it back. The problem? Too much uptime. Monitor Atle - DEC-10 at work System uptime 10483:52:41 Current date/time Thursday 8-Feb-2018 8:00:14 Thats what you get for running stable hardware. On the other hand, this is/was a known problem: MCO: 12935 Name: WXD Date: 22-May-86:14:12:35 [Symptom] DECnet stops working correctly. The -10 sees all the nodes on the ethernet, but isn't seen by any of the nodes. [Diagnosis] The -10 has stopped sending ethernet hello messages. This is caused by the -10 getting an overflow when calculating the DECnet time (milliseconds of uptime), which is then used to determine when to send the next message. The algorithm is: MOVE T1,SYSUPT IMULI T1,1000. IDIVI T1,JIFSEC This overflows at 159 hours, 4 minutes, 22 seconds, and 19. ticks (60hz). [Cure] Change IMULI -> MULI, and IDIVI -> DIVI This algorithm won't overflow until 9544 hours of uptime (395+ days). --Johnny (the other one) /\_/\ ( *.* ) > ^ <

DECnet for Linux

by e.olofsen＠xs4all.nl

On a virtual machine with lubuntu 12.04, kernel 3.2.0, I have DECnet for Linux V.2.5.68s working, with dnprogs version 2.65. It is node RULLFL. The daemons and utilities use decnet.conf with node information, so something useful would be to create it from mim::nodenames.dat. On a VAX, TYPEing it works well, but on the Linux machine, dntype hangs after giving parts of the file; dndir mim:: works well. Does anyone have dntype mim::nodenames.dat working properly (with perhaps different versions of the above)? Thanks!

Announcing TCP/IP for RSX-11M-PLUS

by mark＠matlockfamily.com

Johnny, Using your [IPF77]TEST2.FTN, I made a very simple network printing routine that I can begin to modify for a Brother Laser printer which will have its own escapes codes for portrait, landscape etc. and pull file names from the command line. I show it below in case any one wants to do something similar. I used your MKE and MAKEFILE,; to handle getting the libraries and switches correct. PROGRAM NETPRT INCLUDE 'INET' CHARACTER*40 HOST, URL, FIL CHARACTER*1 TXT(132) CHARACTER*6 EP INTEGER*2 LPO, I, L, K, PORT HOST='192.168.0.27' PORT=9100 LPO = TCP(1,0) IF (HOST2I(EP,6,HOST,40,PORT) .NE. 0) THEN TYPE *,'Failed to convert hostname.' CALL EXIT(1) END IF IF (CONNEC(1,EP,6,PUTXT,60) .NE. 0) THEN TYPE *,'Connect error: ',NETERR CALL EXIT(1) END IF CALL GEP(1,EP,6) IF (IP2HOS(EP,6,RNADR+RPORT,HOST,40) .NE. 0) THEN TYPE *,'IP2HOST error: ',NETERR CALL EXIT(1) END IF TYPE *,'Got connection - ',HOST WRITE(5,30) 30 FORMAT('$FILE:') READ (5,20) FIL 20 FORMAT(A40) L = INDEX(FIL,' ')-1 OPEN (UNIT=2, FILE=FIL(1:L), STATUS='OLD', FORM='FORMATTED', + CARRIAGECONTROL='LIST', READONLY) 40 READ (2,45,END=100) K, (TXT(I),I=1,K) 45 FORMAT(Q,132A1) D WRITE (5,50) (TXT(I),I=1,K) WRITE (1,50) (TXT(I),I=1,K) 50 FORMAT(1X,132A1) GOTO 40 100 CONTINUE CALL PCRLF(1) CALL PUSH(1) CALL SCLOSE(1) CLOSE (UNIT=2) TYPE *,'Net Print Done.'
