Linux route add command failed: external program exited with error status: 2

felipe marques

Hey guys, I am having the following error

The admnistrator of the server in my work does not know how to solve it

He told me to run as root, but I already do it

It was working fine some days ago

 

I read that I had to delete some cache but I don't where I can do it. Please, help, I need this to work.

    where do you see this output?

    You should not configure something at the sophos-CLI.

    i can see the command " /sbin/ip route add 187.63.160.91/32 via 192.168.0.1"  three times ... the first without error message

    so the routing should work. Which problem do you got?

    do you configure static routes within sophos gui?

    check if the route is configured multiple times.

    Ola Felipe,

    try to execute this command on a normal shell prompt with the user you are using for the vpn-client:

    /sbin/ip route add 187.63.160.91/32 via 192.168.0.1

    What's the output you get?

    Did you change the user or his group-memberships, who is using the vpn?

    @: I think he is using a linux vpn client to remote into a Sophos VPN Server

    The host route from the original default gateway to your server is already set, so the route add for the same host gives an error.

    That is normal when you put "any" in the local networks of your ssl vpn profile, you can ignore the error
