Topic: SME 5.1 Beta4 ISDN Errors in Log Files

[Craig]

I have a internal NetJet-s PCI ISDN card from Travers Technologies. The card is detected ok and setup during the installation. When I dial up my ISP I get the following error message over and over again in my log files.

[root@isdn ppp]# tail -f /var/log/messages

I live in Australia and have OnRamp Home Highway which is basically  give you the options of dialling up 64K or 128K ISDN. The difference is that there is no compression enabled by Telstra on these lines.

This brings me to another point. On OnRamp Home ISDN service you can use DOV (Data Over Voice), dial up an ISP that supports data over voice and presto you have a untimed ISDN data call for the cost of a local phone call. The NetJet-s suports DOV I have downloaded the script followed the instructions got connected and still these errors appear in the log files.

By the way I am not connecting to a ISP that supports DOV and it is not turned on in any ISDN init scripts.

Anybody have any ideas on what this could be.

Hi Craig,

Had the same problem on another linux box. It turned out te be a degugging thing. Debugging is turned on the specific ISDN connection is turned on so you see the LCP echo requests which are normally not visable.

How to enable / disable compression I don't know. Maybe this link can help:

Hope it helps,

Well, that's just a sign of a happy connection..
LCP messages are exchanged all the time, they make sure that both sides agree they are talking to each other... ( as in preventing someone hacking your connection). (Very loose translation of the purpose of LCP..

There is a debug option left in /etc/e-smith/templates/etc/ippp.conf/50Generic
which causes this.

use mc in edit mode and remove the bit that says debug, that's all.

The proper way would be to copy this section to /templates/custom of course and modify it there...

The dirty way is to simply goto /etc/ippp.conf, use mc, edit the offending bit, and
you are done. (until you change something in your settings, then it will come back again.) That's the time to have a look how the template system works. Once you get to grips with it, you will see what a magnificant system this is!

I'll have a look at some of my older log files to see if I find the 'compressor' complaints. My gut feeling says, they are ok, nothing wrong, ( but I'll check)

See if this helps..

I will let you know how I get on.
