Hi All,

Can anyone help me to find out the uptime of network interface in linux. is there any log file maintains the network restart activities.

Need to know how long the interface eth0 is running in the server.

Thanks

you can probably calculate from

Quote:

dmesg

or similar log. Just look for last interface start and calculate from current time.

Tested the variant:
# expr $(echo $(date +%s) - $(date -d "`grep 'eth0: leased' /var/log/messages | tail -1 | awk '{print $1, $2, $3}'`" +%s))

The output is in seconds.
