dear mates

my ppp0 always goes down frequently, after user complaints i will be bringing it up manually. Instead is there any other way to check its availability and bring it up auto.

pudhi

pppd monitors itself, you just need to add the option "persist" to you pppd options.

i added this persist in /etc/ppp/peers/mynet,
but the same problem continues.

why is that

Normally it will reconnect.

In some cases where the problem is not a normal disconnect from the remote end then pppd would have generated an error, and gave up.


Setup your syslog daemon to write debug info to a file and see what's going on with it.



/etc/syslog.conf add these lines

local2.* /var/log/ppp
daemon.* /var/log/ppp


then restart the syslog daemon

killall -1 syslogd

add debug to your pppd options and lets see what's happening.

Thanks david

I will monitor and get back to you

Dear david
