Subject2.2.2-ac7 TCP ignores ICMP host unreachable ??
Date
Hi,

Some quick testing reveals that 2.2.2-ac7 ignores ICMP host unreachable
packets when *initiating* a TCP connection:


2.2.2-ac7 (Red Hat 5.2, Pentium 133):
-------------------------------------
verdi /home/robn 23 % telnet 207.90.112.151
Trying 207.90.112.151...
.
.
.
<waiting till time-out>


tcpdump trace:
--------------
23:11:43.393786 verdi.et.tudelft.nl.4194 > dlp1170.dayton.eri.net.telnet: S 80263460:80263460(0) win 32696 <mss 536,sackOK,timestamp 4438482[|tcp]> (DF) [tos 0x10]
23:11:43.665913 dayusr19.eri.net > verdi.et.tudelft.nl: icmp: host dlp1170.dayton.eri.net unreachable



2.0.36 (Red Hat 5.1, 486/33):
-----------------------------
[robn@berlioz ~]$ telnet 207.90.112.151
Trying 207.90.112.151...
telnet: Unable to connect to remote host: No route to host


Sorry, I've no time to test 2.2.2 now. But I can do more tests later
if someone wants more data !

Greetings,
Rob van Nieuwkerk
