Post router - few questions


Hi,

For a linux router serving 4 win XP clients, should the box have 'Large routing tables' compiled into the kernel?

Also, does 'Fast network address translation' in the advanced routing section of the kernel config, make any difference to performance?

Thanks for any help

what manthram said plus make sure you compile in all the
netfilter targets...you'll want a good firewall eventually.

Ok, I'm just trying to debug why when browsing the net from the client machines using Internet Explorer 6, it quite often hangs/stalls loading half way, then will finish the whole page later on.

Thanks

Duncan

this is tough for the simle fact that it works....but its just slow.
ping your router and then a website to see what the times are like. then
ping from the router to the same site and to the clients. that may not do
jack for you but give you ping times.....i dont know man.

pings to the router, from the clients are fine.

Pings to websites spike like hell.
Pings from router to the same websites provide same ping spikes.

I think there is a definite problem with my NTL cable connection, but just can't think WHAT. I have had a cable repull, and a new cable modem, yet the problem still persists.

I think the problem lays somewhere along the line, NTL's end, but has only appeared over the last couple of months. I have had 5 engineers out, all they have done is checked the modem's power levels etc.. I can't get them to fix it!

yea, if you are getting the same slow connection from the router that the hosts
are gettting, then it rules out the connection between teh XP and the Router.
One more thing you could try, connect the linux box directly to the internet (no router) and see if you get the ping spikes on just the windows box alone,
this will further help you rule out (or not) the chance that your router is acting up. basically, if you get the same slowness with just the XP box to the internet, then its not your Linux box causing problems.

also, Cable uses shared bandwidth with local users....has Cable internet
ownership gone up in your area? This would caues a slow down in connection speeds.

Hi,

connected win XP laptop to the cable modem, and still get spikes (although dont seem to be AS bad, may be a coincidence though).

I have phoned tech support and they say there is not an over subscription problem in my area?

Who dat teelin you there not oversubcrption in the area???

ATT or ComimeCast or ROad RUnna

They always say dat.

Mo than likely the problem is with them cause I has been there and bakc with them... Finally they fiugred it out it was a problem at the pole, the other time it was that they changed a router out AND TOLD NO ONE ABOUT IT causing a lot of greif... duh

SO hound them until they scream UNCLE. You will have to get them to do what they are suppose to.

i'd have to agree with ikw, they wouldnt know what over subscription
was if it hit em in the face and called em ugly. Maybe there is no
over subscription problem as far as they are concerened. Here is how you can tell.....get on late at night when most people are sleep, and see if you
get a connection performance boost.....that will let you know. When most
people are sleep, less bandwith is being use.= MORE FOR YOU!!!

if it's still slow, call em up again, and again ...and again....tell the something like "i shouldnt have to pay for poor service", when u start talking about
money.....people seem to listen more. We got our installation fee (200.00)
waived because my dad didnt like the confusion that went on while
we were trying to have DSL installed at our house. He complained, the
took away the fee. But that's 1 case, but stuff like that works often. It
could at least save you some cash if they dont know how to fix it.
