I'm getting a no route to host error sporadically (about 4% of the
time in a 2 hour period) with connecting to a certain host in the UK.
I'm in the US. When trying to track down where this is coming from, I
did a sniffer trace from my end and found that there are *no* ICMP
messages being received regarding this error. How else could a tcp
socket open/send give me a "No Route to Host" message without having
received the ICMP telling it so? (BTW, the host is blocking all ICMP
on its end. I'm not.)
My configuration--Red Hat 7.2, single proc, kernel 2.4.7-10smp, x86
box with 512M ram. The CPU is not all that busy and the system is not
loaded, there is plenty of RAM free, etc.
