No the tcpdump makes no sense to me either!! just curious what os uses
interface ctc0 ?
well your ping packets are returned so routing should be ok..
samba is configured to use/listen-on interface ctc0 right ?
what does smbclient -L winshostname -U validuseronserver return?
if i'm right an error, as the "winshostname" won't be resolved. And
probably no other names either except by "broadcasting" on local lan
when wins-retries time out.
Ahh wait a minute...if some things work and not others...I believe wins
calls are udp protocol based NOT tcp...even though the port nos are the
same. which brings us back to the firewall again!!!!
regards
Richard Coates.
