Package: ifupdown
Version: 0.6.10
Severity: normal
I use netplug to run ifup when an Ethernet link is detected.
The ifup command works at boot time or when I unplug/plug in
the Ethernet cable, but not after a suspend/resume. Logging
shows that the ifup command is run (see below), but it doesn't
do what it should.
My /etc/netplug/netplug script contains:
[...]
case "$action" in
in)
if [ -x /sbin/ifup ]; then
logger "/sbin/ifup -v $dev"
exec /sbin/ifup -v "$dev"
else
[...]
so that the ifup execution will be shown in the logs.
The /etc/network/interfaces file contains:
[...]
mapping eth0
script /usr/local/sbin/guessnet-wrapper
map default: eth0-dhcp
map debug: true
map timeout: 2
[...]
and the /usr/local/sbin/guessnet-wrapper script starts with:
#!/bin/sh
logger "guessnet-wrapper $*"
so that its execution will also be shown in the logs.
After a suspend/resume, I get in the /var/log/syslog file:
[...]

As one can see, the ifup command is run, but not the guessnet-wrapper
script!
After booting, the syslog file contains:
[...]

The guessnet-wrapper script has been run and everything is fine.
