Default Intermittent loss of network function

Hi guys,

I have recently converted to Debian from CentOS/Fedora

Currently I have followed two guides:

http://www.howtoforge.com/perfect-se...er-ispconfig-3

http://www.howtoforge.com/extending-...ze-ispconfig-3

But my issues started to arise somewhere between the setting up of accounts on my system (emails,ftp,websites,etc) and installing virtualbox to run a headless winxp client with spiceworks installed.

Ok so now my issue(s)

- My ventrilo server loses connection repeatedly - probably alive for a hour and gone for about 30 mins.
- At this time I can't resolve dns query's
- I can't ping my gateway from my debian server
- I can ping my gateway from my laptop running win 7
- I can't dig anything but the name of my server (suggests dns is working in house)

Thats my main issue because due to that I lose my website, my mail server, my roundcube access, and my redirect to the virtual machine running spiceworks for help

Please advise???

I have been looking in the logs and I see lots of random things like:

mail postfix/smtpd[3957]: connect from localhost.localdomain[127.0.0.1]
mail postfix/smtpd[3957]: lost connection after CONNECT from localhost.localdomain[127.0.0.1]
mail postfix/smtpd[3957]: disconnect from localhost.localdomain[127.0.0.1]

i get that for mail imapd as well

pure-ftpd logs in and out every 5 mins???

Please help me this is blowing my mind... I had it working "fine" on my fedora machine never lost connection like this...

thank you
steve

You're talking about more then one machine, which one is the one that's giving you problems?

Are the ventrilo, gateway, converted centos->debian server the same machine, or all different?

"pure-ftpd logs in and out every 5 mins???" That's just an ispconfig cron for the monitor in the webGUI to check if your ftpd is still running

Hi Mark

Ok so I have the made a new fresh install of debian built to utilize ISPConfig 3 - I was referring with the centOS comment that a moderator on these forums advised me to go from centOS to debian as a platform to use.

So this is what I have done:

- Debian fresh install > ISPConfig
- Also installed VirtualBox > Running headless image of xp with Spiceworks installed
- Also installed Ventrilo (voip program for my gaming buddies) on the Debian platform

The gateway is my Billion 7800n IP address

Thats about it.

Overnight I tail -f ventrilo.logs and it tells me that I lose network functionality pretty much every hour.

Ok maybe have it solved??

As I followed the extended debian setup I also installed the ddos script that runs... So I went to http://deflate.medialayer.com/ to uninstall it - also noted that a email could be sent to the root so that ip's blocked would be listed... anyway currently it is 4 hours later and not a single drop out of ventrilo... So i'm also hoping not a drop out from any of my services running (email,apache,etc)

Fingers crossed that this was the issue.

I will post back in a day or so if this fixes the problem else I'll post back sooner if it isn't

cheers,
Steve

Haha, so it was your own ddos scanner that kept you blocking? :P

Ok so I thought I had fixed the issue but at 16:23:00 and 16:35:21 my server lost resolvable services. It couldn't resolve the name and so my vent server went down...

Argh... This is just what I didn't need...

Any ideas people? Anyone know where to start looking??

Cheers
Steve
