I shut it off when it started puking like that. THen I cleaned out /etc/hosts/deny.On Wednesday 15 January 2003 10:57 am, Tibbetts, Ric scribbled nervously:Sheesh! NOW, the server (firewall side) is just bulk rejecting ALL connections (again!). It considers any incoming mail as a SYN attack, and rejects it! (egads! I'm getting tired of this chase!). I thought I had this sorted out... /var/log/messages is bing filled with messages like:[snip]It's all incoming mail, that is not coming in! Any thoughts on WHY it would interpret all incoming connections as an attack? Anything not already blocked is interpreted as a SYN attack,andis rejected, and added to the list.... Thanks ! Ric
Ric,
do yourself a huge favor and turnoff and uninstall PortSentry. He's a
tired old man with a serious bladder control problem. he sh*ts himself from
time to time as well. do that and you should be feeling a lot better.
But it's still not accepting any connections, it's just quieter about it. It's just not receiving anything. When it did this the other day, xinetd was down. I checked that... alls well there. It's running.
this is really getting frustrating! If I were 3000 miles closer, I'd shoot the thing between it's transistors, and rebuild it. But I'm just a bit to far away for that.
I can still ssh in, so at least I can work on it. But I'm lost as to why it started doing this again... It was fine, up until about a half hour ago.. Then it just stopped receiving connections. There's nothing in the logs..
I even tried the M$ method: Reboot.. no joy. It didn't help.
And stopping portsentry doesn't make any difference.
It's not the mail system either. I reverted back to the pre-spam filter version. That didn't make any difference.
It's just started rejecting all connections.
gotta be a reason....
