[vfer-users] Can't use vfer_rcp

[Yang <u01...@sn...>]

I've been trying to use vfer_rcp to see how fast files transfer
between two Internet-connected hosts.

[root@harvard vfer-0.98]# bin/vfer_rcpd -vv -P 9876 start

However, on the other host:

I wasn't able to find documentation on these two apps. Thanks in
