No tst_rhost_run is a shell function defined in tst_net.sh.
I guess the problem is your RHOST setup.
LTP supports two setups for network tests:
1. network namespace based. This is used if you don't set RHOST and LHOST.
2. Two-host setup, where RHOST points to a second host.

The important thing in two host setup is, that $LTP_ROOT/testcases/bin 
is in the PATH for the user, that is used on the RHOST.
I guess what happens in your setup is that tst_net_iface_prefix is not 
found on the RHOST, because it is not in the path.
