I am having a very strange problem in linux 2.4 kernels. I have not set
any iptables rules at all, and there is no firewall blocking any of my
outgoing traffic. At what seems like random selection, I can not connect
to IP's yet I can get ping replies from them. Most IP's reply just fine,
but certain ones fail to send even an ACK. This problem disappears when I
boot into 2.2. Here is a brief example of what I am talking about:
meatloop:~>ping 204.202.131.229
PING 204.202.131.229 (204.202.131.229): 56 data bytes

meatloop:~>telnet 204.202.131.229 80
Trying 204.202.131.229...
telnet: Unable to connect to remote host: Connection timed out
[iptraf output]
209.192.217.120:32926 = 6 360 S--- eth0
204.202.131.229:80 = 0 0 ---- eth0
and yet when I boot 2.2, I have not seen any problems of this nature. Is
this a known issue? Possibly a setting in /proc/sys/net/ipv4 that I dont
know about? Thanks for your help...
