How to communicate on /run/frr/ldpd.vty unix socket

[Girish Patoliya]

Hi

I am trying to configure below sequence of commands from a C application.
enable
 configure terminal
    mpls ldp
        router-id 1.1.1.1

I am connecting on /run/frr/ldpd.vty unix socket and trying to write about command on socket fd.

currently write() is failing with bad file descriptor error.

by debugging I found that ldpd.vty is owned by frr:frrvty while my application runs as root.

to avoid this I compiled frr with --enable-user/group=root and vty group as root, still observed same issue.

is there any way to communicate with ldpd.vty from separate C application process?

Thanks
Girish
