Linux – route add error: SIOCADDRT: No such process
I was being shown this message but I knew the operating system was refusing to add the route
root@linux:~ # route add -net 172.22.1.0 gw 172.22.18.1 netmask 255.255.255.0 dev eth1
SIOCADDRT: No such process
I added the route to /etc/sysconfig/network/routes and then restarted the network service
