Legacy Network Woes

[Aaron]

Sophos here would be the biggest sit hit by almost 20,000 i have left it on but its something i might think about disabling down the line.

[Gerard]

Cheers Aaron, will give that a look

Gerard just seeing this now, was off for a few days 


Have you upgraded your Censornet to the latest version as we had a similar problem here and the Censornet upgrade to version 5.2.65.2.6 seemed to sort it out 

Telone - what issues were your having?

Our Internet response gradually slows down & then the Red Broadband light on the BT Business hub 3 switches on.  This means no broadband connection so the only solution is to restart the BT Business hub.

Censornet then obviously complains before it's restarted that it can't look up reverse DNS.

[Telone]

Internet would go very slow then speed up occasionally a restart of the router would be needed but a lot of the time we got could not connect to web page or timeouts 


Have not got around to doing the upgrade to 5.2.10 yet still at 5.2.6 

[Gerard]

Still no further on, bt basically saying there's nothing they can do, as they have tested the line and ruled out the modem saying it's either a problem my end or too many devices on the LAN.

Bt saying so far we have used 126gb in October where as last November we used 660gb and it was working fine :-s

Also checked the sophos Aaron it's not configured to check web pages etc.


Anyone any idea on how to disable dhcp and set your own IP on an apple airport express or reckon picking up a branded router liked link / Cisco would be worth looking at ?


Can't set up the psense as I only have a hub 5 and no open reach modem

[Aaron]

Gerard how do you allocate your IP's do you use your main DC as DHCP and DNS?

[Aaron]

for bt infinity you need to look at a router which supports VDSL then you can use any router that's what i have done in another one of our buildings and kept the BT router for backup.

[Aaron]

do you use any caching at all to try and reduce the load on the router?

[Aaron]

i know or at least i am almost certain if i remember right that censornet supports website caching, also look at restricting down streaming media (these are all just additional things to try of course) but its really strange that you've reduced down by 500gb a month and still having massive issues around the router.

[Gerard]

Cheers AAron,

think i might have stumbled across something when i delibertly kicked the router offline by typing in the ip address into my browser

in wireshark i noticed the spanning tree protocol again and traced the mac addr back to belonging to my router

.. only thing is i have spanning tree disabled on my switch that the router is plugged into- inthe process of checking all my other switches. any idea how to rectify this if it is the cause of my month long headache?


also i don't have any caching enabled though i may have a look at censornet to see if it affects it.

also i use my my DC for DHCP and DNS ( router has DHCP/wireless/bt guest disabled)

i would honestly look at censornet to reduce the load on your router by enabling caching you should notice a large drop over a couple of days in activity on the router.

On the spanning tree could it be a faulty port on the router?

[Gerard]

ill change the port today to see if it makes a difference.

i cant see caching option anywhere on censornet - would they have removed it from the latest version?

defiantly seen it before pre - V5

[Aaron]

i would contact them about this Gerard because i remember it really did make a big difference when i used it so if it has been removed really look into getting something in place to try and reduce the load down on the router, you staff and kids should then notice a difference with it coming across the lan instead of over the net. But def check with censornet incase its more something that's enabled by default during the update or something they should enable for you

[Gerard]

just checked that feature has been removed   if only that riverbed was still on site lol

[Aaron]

lol, look into using squid on a spare machine with a large harddrive that's what censornet used
