[7.090] Launching bittorrent killed webadmin access, and http traffic

I launched bittorent, and it killed my webadmin access entirely, as well as my Lotus Notes access, and normal http traffic.

As soon as I quit the torrent app, everything returned to normal.

It also killed my access to My Astaro, as well as access to my online banking.. almost like the encrypted torrent traffic stopped all encrypted traffic from passing through ASG...

Ok, just heard from my wife, that this also killed her secure SMTP email to gmail while I was running torrents.

As soon as I killed it, it worked for her.

This is pretty bad, since I can basically DoS my household now just by running torrents... haha

I've seen this before with previous versions of V7 ... what happens if you turn off network accounting? What process do you see eating the machine in TOP when this happens? Could be our old friend pfilter-reporter.....

Looks like it might be portscan detection, not sure though.

Looking at top, pfilter-repoter is using 99.4%, even though now I can access things because I stopped my torrents.

Yep, same issue that we've seen before... that process can get nasty when it processes all the drops that Bittorrent causes... not that it's necessarily the fault of Bittorrent, the firewall should withstand drops without "dying"... it's a tough problem, though, from what I understand.

Try it with Accounting disabled (that new feature they added)... I wonder if that will fix it.

Wow.. it was portscan detection. Funny thing is I have had that enabled for a long time, didn't make any changes except the new beta up2date today.

Had to add my laptop to the skip source list for an exception to portscan detection.

That was horrible.

It's likely that it's not so much the portscan detection... it's the massive amount of drops it produced that pfilter-reporter tried to process... kind of an indirect issue -- at least that's my take on it.

Yep, William reported the same issue on v7, oh about 10 months ago and again 4-5 months ago.

HIgh loads on Astaro
possible astaro v7.005 security issue

Not good when you can DoS the firewall so easily. Anyone see if it's possible to do the same from remotely as well? I don't see why you wouldn't be able to...

I run uTorrent behind ASL just about all the time, using v6 and v7... I don't see any performance impact...
Portscan detect, IDS, Accounting etc etc all turned on.

I do as well, and never had to exempt my machine from PSD before. However this time I do.

I am getting this too.  I have a 7.091 box running on a small P3 1Ghz 512 RAM in front of Suse 10.3.  As soon as I brought up Firefox I lost all connection to the Net.  I started top on the Astaro and an ips process eating cycles.

Then I looked in the ips.log file.

2007:11:28-15:54:12 (none) ulogd[2558]: id="2102" severity="info" sys="SecureNet" sub="ips" name="portscan detected" action="portscan" fwrule="60017" initf="
eth0" dstmac="00:04:5a:84:3e[:D]f" srcmac="00:0c:f1:eb:46:04" srcip="192.168.2.20" dstip="192.168.2.100" proto="6" length="60" tos="0x00" prec="0x00" ttl="64"
srcport="50182" dstport="8080" tcpflags="SYN"

2.20 is my suse box, 2.100 is the Astaro.
I started Firefox restoring a session of 4 tabs.  I am using the http proxy in transparent mode.

I did start Azureus about the same time as firefox.  I really am not sure which one caused the issue, but as soon as I changed the ips- portscan setting to log only instead of drop traffic everything was back to being normal.

Similar experience here, launching a torrent will generally peg the CPU %100 until the torrent is stopped, the interface and other network operations will stop (web, email, etc.. all unresponsive).

I have noticed that its a little better in the beta.

Currently running:
P4 3GHZ
1GB of RAM
Intel PRO 100 NIC's

It's tough for astaro. I have never had an ipcop or smoothwall or untangle machine fall over just because of running bitorrent. Also astaro v4 and v5 also never had this issue. It's endemic to v7.
