[Devil-Linux-discuss] connection bounce problem - help

[Leslie H. <les...@wo...>]

I am currently using DL-1.2.13,  shorewall and PPP-OE on my firewall.

In the past I would see 10 to 15 days or more without a connection drop. 
A few months age I started to see a problem where the connection would 
drop for a few seconds and then re-connect every eight (8) hours.

I created a shell script to extract data from the system messages file 
and calculate the connect time. The result shows that the connect times 
are consistently 480.0 or 479.9 minutes each time.

When I contact my ISP (AT&T DSL) they swear they have nothing to do with 
the problem and it must be a problem in my firewall/router.  I don't 
believe them, but I must check.  I have searched the list archives and 
my local configuration.  I see no reports in the mailing-list and have 
found nothing in the configuration that should cause this problem.

Is there anything in DL or the PPP configuration that could cause this 
problem.

Any help would be greatly appreciated.

Hey,

I'm not aware of anything in DL which could cause this issue.
Does the ethernet connection itself go down?
Can you swap the network card to see if it's a simple hardware issue?
Which version of DL are you using?

Heiko,

Thanks for the reply.

I am using Stable DL 1.2.13  and Shorewall 3.2.7.  I verified this by 
using the "shorewall version" command and "cat /DEVIL-LINUX".

I have START_ADSL=yes in the /etc/sysconfig/config file.  As far as I 
can tell, the green lights on the ADSL modem do not flicker abnormally 
of go out. The line bounce at 479.9 to 480.0 minutes is so dependable 
that I have made it a point to be watching when this happens.

I do have a spare NIC - just in case - which I can swap in.  I haven't 
done that yet because I hadn't thought a hardware problem would produce 
this type of symptom.  Since your reply tends to rule out a software 
issue, I will swap the cards and see what happens.

Thanks again.

I'm assuming it's a hardware issue since it didn't sound that you did  
any changes to the software configuration.
The problem could also be your modem or maybe simply the cable, who  
knows. Try the 'cheap' basics first.

But also try to think back if you did any configuration changes or  
software upgrades before it started happening.
