Into Fedora 22 workstation, it's possible to change temporarily via command line the default gateway, to test another gateway, when I have setup the network via DHCP?
What is the best command line to use?
Many thanks
try : $ man route
*DESCRIPTION Route manipulates the kernel's IP routing tables.
Thanks Paul, but in f22 the command "ip r del default" (or ip r rep) not work anymore if the NetworkManager is set to DHCP (see my previous message, Thu, 04 Jun 2015 14:15:59)
Some other suggest?
Couple of possible solutions
1) Put ignore-auto-routes=true into connection file in /etc/NetworkManager/system-connections and restart connection/NM service. This should reject DHCP routes, and you can add routes manually as tmp solution.
2) nmcli con mod --temporary {interface} ipv4.never-default true After that NM will not add default route to that int.
3) In good old days NM honored /etc/sysconfig/network-scripts/ifcfg-interface config, and "DEFROUTE=no" in right place meant no def route for that interface. But I am not sure if it works nowadays, I dont use NM. More no than yes with -NM enabled.
Be careful, don't mess your network by having fun with NetworkManager and D-Bus.
