Utorrent causes internet crash ONLY at one pc, internal lans fine
-
I must have removed snort, I think I had it before bit it doesn't show under installed packages. How do I fully clean it out if it left remants like that?
I rebooted that pc at 8:45am this morning, it JUST went down again at 10am pulling a steady 5.5megabytes down. it hard cuts when it goes down, not a slow drop of clients and problems creep in or anything like that, it's like I just yanked the wan cord as far as that pc sees it.
I did have speed issues with powerd enabled so I did disable it, I have pfsense installed in a thin client with a p3 733 and 512mb ram, dual intel pro 10/100 card. I have encryption forced on outbound connections, I have noticed cpu usage can get pretty high when any ssl traffic is passed.
How can I see what rule blocked it? I go to status > system logs > firewall and see the list there.
Entries just look like below (with ip's removed):Apr 12 09:12:42 WAN (Source outside IP):60658 (My IP):7121 UDP
-
Hmm, I'm not sure about Snort. I've not seen it myself but I've seen other mention it before. Mostly I think it was a problem where Snort would block something then it was uninstalled resulting in no way to unblock it. Left over block rules.
Ah, Bytes not bits and a P3 not a 5800K (must read better!) would explain the CPU usage. You should almost certainly not have powerd enabled for that. Only the mobile P3 had speedstep and I don't think it was supported anyway.
How can I see what rule blocked it?
I knew you'd ask that and the answer has temporarily escaped me! ::)
Thinking about it the blocked udp packets during a download are not that important. What would be interesting is looking in the firewall logs after your client has stopped being able to reach the internet. Try to open a few web sites or whatever and then check the logs.Steve

This time it only lasted 30 minutes before crashing, it just went down again.
I disabled PFblocker to see if that was doing anything and it did not change anything.I also just disabled the bogon network rule and all other firewall rules just… didn't exist.
So why does my firewall log still show as LOADED with entries? 50 entries view is only spanned over 1 secondEDIT
I found out how to view what triggered it by clicking the red x
the rule that triggered this action is:
@1 scrub on fxp1 all fragment reassemble
@1 block drop in log all label "default deny rule"I also found this explanation:
http://doc.pfsense.org/index.php/Logs_show_%22blocked%22_for_traffic_from_a_legitimate_connection%2C_why%3FSo looks like that's normal, dead end.
-
By default pfSense blocks everything everywhere, the 'default deny rule'.
If you have been running a P2P application you will see a large number firewall hits as other clients worldwide attempt to connect to you. This can take days to timeout.
What firewall entry was that for? During download or after it failed?
Steve

uTorrent uses UDP connections as well. Take note if the UDP port number is the same as uTorrent's defined port number. Though this is unlikely why your connection drops off, just an explanation of why you see massive UDP connections.
If you go to Status > Services, do you see snort listed?
When you say you run pfsense as a thin client, I take this to mean you have a separate white box running vSphere with pfsense as a virtual machine? While your uTorrent box is a separate/dedicated computer?
With the above being true, if restarting the uTorrent box restores connectivity then the issue is solely the uTorrent box at fault.
DNS resolution isn't definitive, as it could pull from cache. With pings timing out I'd go as far to say you have 0 connectivity, not limited. Download the Windows XP Mode from download.microsoft.com which should be about 400-500mb and will max out your speed.
This way it's a single connection pushing 5mbps easily. You can rule out if it's uTorrent's fault, the number of connections, or if it's going too fast.

Heavy1metal:
no I don't see snort listed under services listed
I run pfsense on an old thin client for the hardware, a wyse type box as a glorified mini computer - not virtualized. From there I plug into a gig switch which runs to my desktop pc having the issue and my other computers having no issues at the moment. I
DNS isn't pulling from cache because I am randomly asking people for websites that i have never before visited - they are all fresh pulls.
If I close utorrent on the desktop the issue does not go away. If I reboot the pfsense machine it does not solve the issue either… but how could utorrent break the connection ONLY at that pc and ONLY to wan traffic? what could be done locally to cripple wan but not lan? That is the strangest part...Stephen:
That was during download after rebooting it.
The entries look similar after it crashes. I just went down again and the entries for firewall are the same type and around the same frequency.
Mostly udp, some TCP:S, some TCP:R, some ICMP6, all WAN. I turned off logging of default rule blocks and then tried checking a web page - nothing new showing up, firewall is empty.That being said: I have vmware workstation loaded on my desktop. I just fired up one of the virtual machines and attempted to pull up a web page - same end result for what it's worth. I also remotely connect to my desktop during the day with teamviewer and leave the connection open. I know the issue happens when it does because my remote connection drops. When that happens I teamviewer to my laptop to rdp into my desktop and troubleshoot.
-
what could be done locally to cripple wan but not lan?
Change the default route information or gateway. Then you have access only to local subnet services. That would include the DNS forwarder in pfSense. Of course I have no idea why it might be doing that. Rogue DHCP server on your network? That happens surprisingly frequently and can cause all manner of problems.
I suggest you run an 'ipconfig /all' on your Windows box before and after failure and compare the two.
That being said: I have vmware workstation loaded on my desktop. I just fired up one of the virtual machines and attempted to pull up a web page - same end result for what it's worth.
Is this the same machine you run utorrent on? You mean a VM running on that machine after it fails to connect also fails to connect?
Steve
-
ipconfig nets the same IP. if I do a release/renew it does get an IP (same one) from pfsense and gateway is the same. It behaves the same both before and after restarting the pc.
Correct, once my desktop no longer communicates with the internet, the vmware machine running on the same desktop pc also has no internet access.
-
Is the VM getting a new IP from pfSense or is it NATed from the host machine?
What about the routing information, try 'route print' before and after failure.
Steve
-
VM actually grabs via pfsense, it shows up in the arp table there.
Here's a fresh route print before failure (192.168.1.1 is the pfsense machine, and 1.11 is my desktop):

Hmmmm. :-\
What do you have between the pfSense box and the client? Assuming you have some switch does it have any features that may be contributing to this? Have you tried power cycling the switch? Have you tried removing the ethernet cable from the client?
Otherwise I'm stumped!
Steve
-
yea this is a real tough one. It's just a standard trendnet gig dumb switch, nothing to it… no features. I haven't bounced it yet or messed with the cable because of that. Nothing else in the middle

To update anyone with similar issues, dropped to uTorrent 2.2.1 Build 25302 (but kept settings) issue persisted.
Tried installing Vuze and seeing if it works. I had the same thing happen on vuze, guess it wasn't utorrent kicking it off just torrents in general.I since rolled back to 2.0.0.4 and also tweaked my network adapters settings. I disabled both vmware network adapters, then went to config my main adapter - disabled vmware bridge protocol and "AppEx Networks Accelerator". I think the AppEx piece was my problem, looks like it stems from something called "AMD Quick Stream Technology" - an AMD QOS shaper that must have come with my motherboard driver pack.
Since then I have downloaded 1 Terabyte and not had a single crash while before I couldn't break 20gb at times. I hope this helps someone else ripping their hair out.
Mystery solved, thanks everyone for their time and help.
-
Good sleuthing. :)
Seems like a useful technology then. ::)Steve

I have the exact same problem that is causing me a lot of grief the problem is when the net goes down (my entire network) my vpn crashes too and NOTHING internet related works even when I shut off utorrent the net remains down untill I reboot the pfsense AND reset the modem. If I don't do this my net remains down.
I just installed the latest version of vuze and I'm trying it now but seeing as this is a problem for you too I may try and revert to to utorrent 2.0.0.4 if vuze causes the issue too.
Thanks I will keep you posted on my findings.
I do have
HVAP
Squid
Squid Guard
and PF blocker running I downgraded toPFsense assuming the newest version was causing the problem, even with the older version I have this issue.
2.0.1-RELEASE (i386)
built on Mon Dec 12 18:24:17 EST 2011 -
vuze just crashed too, now I installed utorrent utorrent 2.0 build 17920
I'll run it after lunch, it usually crashes within 20 min
I'll report back.
-
@nambi - What is in the pfSense system logs prior to the network going down?
I assume you pfSense box is hitting a limit somewhere–CPU, RAM, etc.--and that's causing the box to lock up.
-
my pfsense just crashed again here using an old version of Utorrent.
This is what I notice, when the net crashes I http into the pfsense box, the GUi comes up very slow with 1/2 of it, not showing eventually the screen shows the full UI.
In the logs I see errors upon connecting to the IPSEC and other services that require the internet.
The memory is at 14% (4gm ram)
the cpu (intel atom d525) is at 4%the only thing I see in the logs is.

This is clearly a completely different problem to tastyratz issue. It's effecting your whole network not just one machine as the title suggests. Since he solved his issue I guess he won't mind his thread being hi-jacked. ;)
Since you are using torrents I would first guess that you have hit a limit in the number of connections allowed. With 4GB in your pfSense box it shouldn't be a problem. How is your modem configured? Is it in bridge mode?
Look at your MBUF and states usage in the dashboard before you start the torrents and monitor it as the torrents pick up.
Steve
-
Thanks Steve I'll start a new thread so I don' t hijack this one.
I'll try your suggestion tomorrow when I have others off the system
Can you tell me what
"MBUF" is? Another really weird characteristic is, my local server which services files for our DB is inaccessible when this happens.
CPU usage is below. My UPNP is disabled should it be enabled?
When the system is crashed.
