I am using diald to dynamically connect to the internet; when doing a test run with 2.2.1 I see lots of messages in the syslog like
Feb 16 21:29:09 ntserver diald[227]: Closing down idle link.
Feb 16 21:29:09 ntserver diald[227]: Nonzero exit status (7) on command '/sbin/route add 192.168.254.200 metric 1 dev sl0' Feb 16 21:29:09 ntserver diald[227]: Nonzero exit status (7) on command '/sbin/route add default metric 1 netmask 0.0.0.0 dev sl0'
Feb 16 21:29:09 ntserver pppd[893]: Terminating on signal 2. Feb 16 21:29:09 ntserver pppd[893]: Connection terminated. Feb 16 21:29:09 ntserver pppd[893]: Hangup (SIGHUP) Feb 16 21:29:09 ntserver pppd[893]: Exit.
Feb 16 21:29:09 ntserver diald[227]: Nonzero exit status (7) on command '/sbin/route add 192.168.254.200 metric 1 dev sl0' Feb 16 21:29:09 ntserver diald[227]: Nonzero exit status (7) on command '/sbin/route add default metric 1 netmask 0.0.0.0 dev sl0'
Feb 16 21:29:10 ntserver diald[227]: Delaying 30 seconds before clear to dial.
I don´t know exactly what diald does to the routing table but might this be the same problem? Details on request...
