The "Operation not permitted" is usually due to a firewall misconfiguration
or a non-completely working network card. It happens to me from time to
time when one of my VPN is busted (virtual interface stopped working),
usually taking down the virtual NIC and restarting it fixes the problem.

The fact that you said one in ten goes trought make me think of something
more hardware related.

Hello all,

I am having a problem with a Linux (Slack 10.1 w/ kernel 2.6.10 w/
Julian's dead gateway patch) router which every other day or so stops
functioning correctly.

It is a load balancing router utilizing four DSL modems and iproute2
with the "ip route replace default eualize nexthop ...." way of doing
it. It works beautifully 90% of the time but every so often it will
fail "partialy"

I can still download fine. If I FTP into a server it will work with a
stunning 3.5mbit/s but some webpages will fail to load. When I ping
those pages I get a daunting "ping: sendto: Operation not permitted"
Every one in ten pings do make it back though, but the other nine give
me that error message.

A reboot of the system fixes the issue for a day or two but I'm looking
for the cause of the problem, I am wondering if anyone has seen this and
knows a way to fix it. /var/log/messages has nothing in it before the
router starts to malfunction. Any ideas?

Thanks in advance,
Kevin Brown.
