Hi all,
My isp blocks traffic on port 25. So i decided to experiment on adding
a listening port for sendmail. I added port 53, because this is never
blocked. I added the following line in sendmail.cf: OOPort=53. I
killed -1 sendmail. And then all my connections timed out. Ping gives
a 80% loss. Are there that many wild dns requests? The box doesn't run
his own dns-server, nor is it registered as one. I'm running OpenBSD
3.7 on this one. Any thoughts?
After my colocator fixed the switch, I was able to watch statistics on
data traffic. There was minimal traffic, so no DOS attack ;-)
Requested a reboot and everything was fine again. Port 53 didn't work
properly so i used 26 instead. Now it works fine. Probably a dangling
bit somewhere.
Kind regards,
Jasper
