Add ip route during runtime

Hi,

is there any way to add a route to my ip configuration during runtime?

I should assign the same configuration that I can define with this command from terminal:

ip route add {NETWORK/MASK} via {GATEWAYIP}

but I would like that the project itself could assign it (I have variables containing required IP addresses).

I know that is a root configuration from terminal, so using PBCL_SysLinuxShell_1 is not possible.


Is there any FB or any other way?


Thanks,

Marcello

    Hi!

    As variant, you can modify sudoers config, to allow plcnext_firmware user to execute /sbin/ip command as root and without password involve. That can be one of workarounds. And PBCL_SysLinuxShell_1 can be used in this configuration .

    In file /etc/sudoers.d/axcf2152-sudoers

    add line plcnext_firmware ALL=(ALL) NOPASSWD: /sbin/ip

    Please, be careful, when deal with this operation. It can damage your system in case of mistake.
