Hi Johnny. New bridge.c compiled. Seems fine in GCC, MIPSpro is still too strict. Build output and config are as follows: jazz:~/src/HECnet[97]%cc -O2 -o bridge bridge.c -I/opt/skunkware/include -L/opt/skunkware/lib -lpcap cc-1515 cc: ERROR File = bridge.c, Line = 229 A value of type "int" cannot be assigned to an entity of type "char *". p = index(dst,':'); ^ cc-1185 cc: WARNING File = bridge.c, Line = 578 An enumerated type is mixed with another type. d->type = classify_packet(d); ^ cc-1171 cc: WARNING File = bridge.c, Line = 684 The indicated expression has no effect. if (port == 0) port == DPORT; ^ 1 error detected in the compilation of "bridge.c". gmake: *** [bridge] Error 2 jazz:~/src/HECnet[98]%gcc -O2 -o bridge bridge.c -I/opt/skunkware/include -L/opt/skunkware/lib -lpcap bridge.c: In function 'add_bridge': bridge.c:218: warning: incompatible implicit declaration of built-in function 'bzero' bridge.c:229: warning: incompatible implicit declaration of built-in function 'index' jazz:~/src/HECnet[99]%file bridge;ls -l bridge bridge: ELF N32 MSB mips-4 dynamic executable MIPS - version 1 -rwxr-xr-x 1 uridium clowns 302060 Jun 7 16:25 bridge jazz:~/src/HECnet[100]%cat bridge.conf [bridge] local ec0 update tempo.update.uu.se:4711 [decnet] local update [lat] local update #### Looks like some casting might be in order. I think I'm ready to go with the port forwarding and bridge setup on this end. Spotted a nice guide a while ago as to how to configure the decnet side of things. I'll follow that guide once the bridge is up. :) Al.
