There are some of you who may have noticed the tunnel system trying to update my tunnel with a source IP of nothing.
I've fixed the script which populates the db with my home IP address so that will not happen again.
I also added data sanity checking code to the tunnel config system to better deal with this sort of thing in the future. A blank IP would actually cause the pySNMP module to explode into flames and bring the entire thing down. :)

My fingers crossed.....
Should work. You might possibly want to mount the devices foreign, but otherwise you should be good.
I've never had to use the /DEVICE switch. It works correctly by default.
You might like using the /STATUS switch, to see the progress.
I think I'll go crank up the 730 to copy the RL02...
:-)
Sadly the 730 doesn't boot. I was afraid it wouldn't - the RA81 is being
cranky. "Servo fine positioning error" (which probably means "the HDA is
trash"!) Those things are not particularly reliable, but there aren't many
alternatives for disk drives.
Check that the transport lock isn't engaged.

I need some modifications made, please.
Change the source int for the tunnels to Dialer0 and set the hostname you
use to dev.gimme-sympathy.org. I intend to switch to a static plan soon.
( My edge is currently a 3745 and I haven't quite figured out NAT and port
access so it may not be allowing SNMP in. ;) )
Thanks!

Fortunately error free RL02s aren't that unusual, even today.
If you can get that, then you're good.

Eh... BAD is a BAD idea in this case.
I disagree - how else will you know if it's error free?
Well, BAD will do the checking, and with the right switches will tell you what bad blocks it finds, so from that point of view, sure. But do not expect the copy operation to care about what BAD found out. But if you just want a verification that the pack is error free, then sure, it will do that trick for you.
But check the /IMAGE switch to BRU...
Umm...
> HELP BRU /IMAGE
BRU>/IMAGE:SAVE source target
:RESTORE
/IMAGE specifies that you want to do a multivolume disk-to-disk
backup or restore operation.
.....
Doesn't sound like what I want. [It's odd - VMS BACKUP has a /IMAGE
option, but it does something entirely different.]
Ok. Checked BRU and /IMAGE is not useful here.
VCP will do the trick for you, but for that you need the latest version of RSX. If you have that, the command is just VCP COPY
All that said, it's about 10 lines of MACRO-11, if you want to keep it very simple.

FWIW, the pack is from an ancient Unix and is not in Files11, RT11, or any other format that RSX knows about.
Given it's from an ancient UNIX system, why not let UNIX do the work? What model PDP-11 is it and I assume is has an ethernet if it's on the DECnet?
I'd just fire up a minimal *BSD for the PDP11 [which has ethernet drivers] and then do something in the scheme of:
dd if=/dev/[raw RL device] ibs=20480 obs=1b | [rs]sh some_remote_host dd ibs=1b obs=20480 of=diskimage
Once you have it in a file, you can mount diskimage in simh on get the data you want using whatever OS or system you like.
Note you might want set the ibs=1b and add conv=sync,noerror to minimize effects of bad blocks, since you are more interested in saving data then speed. You'll want to log/save away the console log so you know where the bad blocks are, since they will show up in the results as blocks of zeros.

We used the trick a couple of years ago, al biet was saving a bootable (DOS11) tape of an ancient UNIX file system. Worked like a charm. Warren Toomey now has the resulting bits on his PDP heritage site.

But if RT-11 uses this device driver even when reading the disk without
trying to handle it as an RT-11 file system, then the RT-11 device
driver can't be used at all if you want to read foreign packs.
There's a .SPFUN to bypass RT's private bad-block replacement (yes the list
is in block 1), so you can easily write a small program to do the copy, but
I'm 99% sure COPY/DEVICE will just use .READ so, bad news.
Writing a stand-alone program to copy RLs would be straightforward, if you
wanted to be done once and for all.
Yes, you could easily do a trivial copy program standalone.
However, we still have the problem with any actual bad block mismatches between the two packs.
There is no real good solution here. Find error free packs is all I can say.
As for the original question, under RSX, there are several ways, as have already been mentioned.

Hello!
How the <BLEEP!> did you manage to get a big IBM thing into your place
that only plays with IBM mainframes? (And then decidedly persnickety
as well.)
