It's not clear to what your problem is.
And perhaps my knowledge of this network protocol is too limited
When I have 2 Pardus computers in a LAN-network and have the following settings on the remote computer.
Systemsettings > Service manager > openssh = running.
Network Manager > Nameserver Settings > Machine Name = wind-u90x
On the local computer in Dolphin > Network > Network Services > Remote disk (fish) > wind-u90x
And through wind-u90x (= fish://wind-u90x.local:22/home/my_usersname) I can connect to the remote computer.
