 Posted: Tue Feb 25, 2003 10:38 pm Post subject: VPN causes problems in Metalog? |
 |
|
Hi all,
I use VPN to connect to the internet. This is done with pptp and mppe. And it works! I wrote my own init-script to load it on bootup 
The problem is that after a while (let's say 6 hours, but I have noticed no connection of my problem with uptime) my connection fails, and I can't login anymore.
I think the problem might be connected to metalog, because logging stops at about the same time... Of course it could be the other way round, but then the question is: why does metalog give up?
More specific info:
- No internet means: I can ping my local subnet, I can ping my VPN router, I cannot ping anything outside (at least not using url's, maybe with ip's it works, I did not test that, it might be only a DNS-related problem)
- I can't login means: 'su' asks for a password (as usual), I type the password and it locks (no high cpu-use or any other anomalies). Logging in at console doesn't work for normal users or superuser (typing password and after 60 seconds I get a time-out message)
- My init-script is in /etc/init.d/net.ppp0. When the problem occurs, 'net.ppp0 status' prints "* net.ppp0: started" but it locks (ctrl-C helps). This does not occur with other init-scripts. My init-script doesn't provide any status () function that could make it crash.
- Logging with metalog in asynchronous mode (yes, I should do this different for this line to make any sense, but my system isn't thAt loaded, so it is actually quite synchronous): I am logging a lot to /dev/tty10, when the problem occurs no further output is written there (even not the regular cron-loglines).
Thanks if you can help me, because I have absolutely no idea what the problem is or even what it can be!

Metalog uses standard config (with in /etc/conf.d/metalog the option "-B").
PAM (if the problem would be in authentication) is still in freshly emerged shape.
My init-script for VPN-connection (sorry for your precious screenspace):
(the scripts post-eth0 and post-ppp0 do some routing stuff, only using /sbin/route)

Oh yeah, one last thing: yes, I know that you have to be in the wheel group to 'su' to root, so please don't remind me of that...  |

Hello,
Problem not yet solved, but I tracked it down to a more basic level. Problem is the same as in https://forums.gentoo.org/viewtopic.php?t=13375.
I'll put any further posts in that thread.
greets
