- Plesk 12.0 for Linux
When attempting to add IP ranges in Plesk > Tools & Settings > IP Addresses > Add IP Address the following error appears:
Error: ifmng failed: SIOCGIFADDR: Cannot assign requested address SIOCSIFBROADCAST: Cannot assign requested address SIOCSIFFLAGS: Cannot assign requested address /sbin/ifconfig 'eth0:32' '22.214.171.124' netmask '255.255.255.240' up exited with non-zero status 255
The issue is caused by the fact that such IP already assigned to a network interface:
# ip a | grep 126.96.36.199
inet 188.8.131.52/28 brd 184.108.40.206 scope global eth0:19
This is Plesk bug with ID #PPPM-4569 , which is planned to be fixed in future Plesk updates.
Shut down or remove the network interface using CLI. Here is an example for
ifconfig eth0:19 down
Add it back using Plesk functionality: Plesk > Tools & Settings > IP Addresses > Add IP Address .
Add IP Address
functionality, Plesk adds IP addresses to OS and to Plesk. If it is needed to add all IP addresses on the server only to Plesk,
Plesk > Tools & Settings > IP Addresses > Reread IP
option can be used.
