[opensuse] logging internet connection status
I have an ADSL connection to the Internet. Recently there have been some problems with my phone line, which set me thinking. Is there a standard way to make a log of my internet status (i.e. connection or no connection?) Or perhaps it's already logged and I just need to extract it?

If you have an ADSL router they usually include a logging facility of some sort. In some cases you can configure them to send syslog messages to a linux box. - -- ============================================================================== I have always wished that my computer would be as easy to use as my telephone.

Cheers, Dave Hi Dave,
Just a few pointers you may wish to investigate. You could try using a network monitoring tool such as Nagios (<http://www.nagios.org/>) or a logging and graphing tool such as rrdtool (<http://oss.oetiker.ch/rrdtool/>). Both are provided as RPM packages on OpenSuSE. Having SNMP support on your ADSL modem/router would make the task of monitoring it easier. HTH Cheers. Bye. Ph.

Thanks, I'll investigate these.

Thanks, I'd prefer a solution that didn't involve the router. A previous problem proved to be a faulty router (the current problem is the phone line) so I'd prefer a monitoring technique that doesn't involve trusting the router. But I'll see what it offers as well. Cheers, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

But you will not get any ADSL link information which is a good indicator of ADSL synchronisation and connection problems at the level below TCP/IP, which is good indicator of line issues (AFAIK NAGIOS deals with TCP/IP not with ADSL connection issues, all you will know is the connection is not working not many clues as to why it is not working). - -- ============================================================================== I have always wished that my computer would be as easy to use as my telephone.

I appreciate that. If the router is reliable then its logs are preferable. But if it becomes flaky and randomly reboots like my last one, I want to have some external evidence squirreled away. I'll try to set up both. Thanks, Dave -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Again, like problem Carlos had with password for an ssh session: use Expect, at least, if your ADSL modem has a telnet interface. #!/usr/bin/expect -- set timeout 60 spawn telnet st546 expect "Username :" send "admin\r" expect "Password :" send "xxxxx\r" expect "=>" send "adsl info\r" expect "=>" send "exit\r" =>adsl info Modemstate : up [..] Put the script in a cron job and extract the data you want with grep. With pyexpect and pylab you can make nice looking graphs. Theo -- Theo v.
