Censornet running slowwwllyy!

[markman]

The Internet has slowed right down coming through our CN box, reboots haven't cured it (this is the limit of my knowledge here ops: ).

Our admin network which doesn't go through the box is fine, I know there should be some slowing with the filtering but this seems more like dial up speed??

[Geoff]

Sounds like the box doesn't have enough memory in it? What is the memory usage like?

Hint: Run 'free -m' from a console window and pay attention to the 'free' and 'used' totals.

You can look at the home page on the web GUI to see the vital stats.

[Geoff]

Fair enough. I'm not familiar with CensorNets web interface (and I figure there's no harm in educating people the ways of the command line either).

[ChrisH]

Come on Geoff you know they scare easy. Its the command line interface its so dark and uninviting .

[leon]

You could try disabling fsynch() calls in the config -but make sure you have the box imaged first and are running it on a UPS as it can jepordise the db integrity. This made a noticable difference to our CN box and it's been running without a hitch for a couple of months.

You know you can change the colours used in terminal windows if you don't like the default white on black. :P

Yes but that would require them getting over their initial fears to do that :twisted:

Can you reduce cache size in CN? That has been known to free up resources at times.

[markman]

Th GUI shows:

Uptime: 1 dat 5 hours
Load average (1 min): 0.2
Load average (5 min): 0.7
Load average (15 min): 1.2
Active processes: 173
Free RAM: 73%
Disk space: 74122MB
Used Space: 3574MB
Free Space: 95%

How do I reduce the cache size? Yes I know, I really should take some time out and learn Linux!!

Cheers

Mark

[tom_newton]

mark: ISTR being able to do it in the GUI, but TBPH I have not looked at CN in at least a year.

[ChrisH]

You need to log into the cli and type "setup" you will find it under one of the menus.

Clear the squid cache. :-)

Happened a couple of times on our boxes.

How many concurrent users are hitting that box and is it authenticating against anything or do you have authentication disabled? Reason i ask is that you have quite a few processes running. If you dont have authentication running i'd probably start looking more upstream than anything else. Maybe reboot your router if you're running in bridge mode.

[markman]

It is using AD for authentication, we could in theory have 150ish at some points on the Net in the same lesson, maybe more if we have cover teachers in suites.
