Thanks for the help everyone - it isn't working yet but I appreciate the suggestions I've been looking into tcpdump and tethereal (I don't have gui since I'm connecting to the remote machine via ssh) Anyway, when I drop my local firewall (I need to spend a little time and make a hole through port 25) run tcpdump in one terminal and telnet 66.11.164.106 25 in the other window I get no response from the local machine (output below) Output of the same thing with port 110 (as a test) is also included below I don't think this shows us anything (does it) # tcpdump tcp port 25 tcpdump: listening on eth0 10:54:23.264863 192.168.1.11.1324 > mail.johnson-engineering.ca.smtp: S 1950223422:1950223422(0) win 5840 <mss 1460,sackOK,timestamp 6411622 0,nop,wscale 0> (DF) [tos 0x10] 10:54:26.258319 192.168.1.11.1324 > mail.johnson-engineering.ca.smtp: S 1950223422:1950223422(0) win 5840 <mss 1460,sackOK,timestamp 6411922 0,nop,wscale 0> (DF) [tos 0x10] 10:54:32.258683 192.168.1.11.1324 > mail.johnson-engineering.ca.smtp: S 1950223422:1950223422(0) win 5840 <mss 1460,sackOK,timestamp 6412522 0,nop,wscale 0> (DF) [tos 0x10] 10:54:44.259417 192.168.1.11.1324 > mail.johnson-engineering.ca.smtp: S 1950223422:1950223422(0) win 5840 <mss 1460,sackOK,timestamp 6413722 0,nop,wscale 0> (DF) [tos 0x10] 10:55:08.260902 192.168.1.11.1324 > mail.johnson-engineering.ca.smtp: S 1950223422:1950223422(0) win 5840 <mss 1460,sackOK,timestamp 6416122 0,nop,wscale 0> (DF) [tos 0x10] # tcpdump tcp port 110 tcpdump: listening on eth0 11:00:25.293908 192.168.1.11.1326 > mail.johnson-engineering.ca.pop3: S 2333763596:2333763596(0) win 5840 <mss 1460,sackOK,timestamp 6447823 0,nop,wscale 0> (DF) [tos 0x10] 11:00:25.381800 mail.johnson-engineering.ca.pop3 > 192.168.1.11.1326: S 2336921751:2336921751(0) ack 2333763597 win 5808 <mss 1360> (DF) 11:00:25.381966 192.168.1.11.1326 > mail.johnson-engineering.ca.pop3: . ack 1 win 5840 (DF) [tos 0x10] 11:00:42.387781 192.168.1.11.1326 > mail.johnson-engineering.ca.pop3: F 1:1(0) ack 1 win 5840 (DF) [tos 0x10] 11:00:42.470859 mail.johnson-engineering.ca.pop3 > 192.168.1.11.1326: . ack 2 win 5808 (DF) -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list
