@tcp is just a shorthand for @tcp0 - they are 100% equivalent to each
other.

Please do "lctl list_nids" on the client and the MGS, and then
"lctl
ping 10.0.68.102 at tcp" from the client and show us the outputs please.
Before running the commands please "echo +neterror >
/proc/sys/lnet/printk" on client and server, and gather any console or
dmesg error messages after the commands have been run.
