[cobalt-users] RAQ3 Loosing Network Connection

[Chae <chae@xxxxxxxxxxxx>]

Hi Yah,

Thanks to some off-line replies to a problem I've had with a RAQ3 which 
looks like it's loosing it's connection to the network.

Have dug up some old archives regarding similar problems...

Thank you to the gentleman who replied off-line and told me to set-up a 
ping process to the gateway IP - Unfortunately this didn't help :(

Then I found an archive where someone with a RAQ4 had the same problem and 
they tried to resolve it by setting up a wee script to do the following:-

/etc/rc.d/init.d/network [stop] then [start]

So with nothing to lose I set-up my own wee cron job to run on the hour...

This is what I get back obviously xxx.xxx are my allocated IP's

Now here it shows two IP's that are not allocated to us 244.155.79.186 & 
244.155.79.187 - these IP's still belong to ARIN. Telephoned my colo up and 
asked them to resolve the issue and could this be the cause of my server 
randomly dropping it's network connection... Yes was the answer, you'll 
have endless network issues with that. So being the nice chap that I am I 
phoned up again (half-way round the world at peak time) can you remove 
those IP's please I asked...yep! was the reply.

Nearly 10 hours later - 3 more phone calls - and two different techos the 
problem still hasn't been resolved :(

Can anyone suggest where I can go on the server to remove any of the 
entries shown, where the entries may be hiding and what files/procedure 
would be needed to remove these...anyone know suggest what I can tell the 
techos at the colo to do - now no rude comments please :)

Many thanks in advance
