Hi, I was testing IPchains and found that Telnet (or the kernel -- 2.0.32) seems to ignore an ICMP port unreachable. I used telnet to telnet to a box, but I have a chain rule that REJECTs such attempts. On the source box, using tcpdump, I see the following: pc1.1024 > pc3.telnet S ... pc2 > pc1 icmp: pc2 tcp port telnet unreachable [tos 0xd0] Where pc3 is reachable via pc2. However, telnet keeps soldiering on, and times-out after a long time, rather than give up when the ICMP port unreachable comes in. Does anyone know how to change this behaviour? Can it be changed?
