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?
