I was getting really frustrating about “Address already in use” warning each time
starting SAMBA and from time to time entering my main logs.
The warning was :
Jun 26 10:32:18 server1 smbd[13902]: [2012/06/26 10:32:18.286523, 0] smbd/server.c:500(smbd_open_one_socket)
Jun 26 10:32:18 server1 smbd[13902]: smbd_open_once_socket: open_socket_in: Address already in use
There is a solution. If you are not using IPv6 then we are good to go.
Just disable IPv6 globally on your Linux System.
echo 1 >> /proc/sys/net/ipv6/conf/all/disable_ipv6
Or you could also just configure it in sysctl.conf to have it across reboots.
echo " " >> /etc/sysctl.conf echo "# Disable IPv6 Globally" >> /etc/sysctl.conf echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf sysctl -p
No more “address aldready in use” bullshit entering your main log files…
