Re: [cobalt-developers] Strange errors in mail log




Paul,

I know it isn#t the perfect solution but please use the Adaptive Firewall and block those ports for IP addresses not beeing trusted or not in your LAN. This works for me and it is much better than the inbuild kernel firewall.

You get the Adaptive Firewall via BlueLinQ and it's free.

Please don't use the latest kernelupdate for the Qube. Stay with kernel version OS 6.4

Regards

Uli

My Qube has recently been a target of spammers.  The problem was due to my
ignorance.  I enabled web-caching which caused an open-relay for spammers on
port 3128. I disabled the port using the web interface and the problem still
existed.   I had to manually kill processes before it was truly disabled and
the open-relay problem ended.

*Sigh*

Monitoring the mail logs like a hawk.  I'm consistently seeing these errors
every 15minutes or so.  Any information would be greatly appreciated.
