Random issues
Posted: 25 Aug 2020, 22:02
Hello,
A couple of weeks ago, one server started to behave very strange. Sometimes websites don't work. But after 10 sec they are working.
cPanel takes sometime 1 minute to load and emails are getting errors in customers email clients.
We also get trown out of ssh pretty quickly.
Only way to fix the issue is to disable csf -x.
I see this when I restart csf:
INVALID tcp opt -- in !lo out * 0.0.0.0/0 -> 0.0.0.0/0
INVALID tcp opt -- in * out !lo 0.0.0.0/0 -> 0.0.0.0/0
DROP all opt in * out * ::/0 -> ::/0
INVALID tcp opt in !lo out * ::/0 -> ::/0
INVALID tcp opt in * out !lo ::/0 -> ::/0
Can that have something to do with it? Have checked white/black lists aswell, but cannot find these.
And why is there no dates on the changelog?
