Lisa is a deamon, provided with KDE, which explores the network looking for some common services (AFAIK smb, http, ftp, nfs) and it is used by KDE to show a "network neighbourhood". To use it you have to start
/opt/kde/bin/lisa (IIRC it has to be as root).
I had it runing once, but since I never actually used it, I removed it. I can't remember exactly how it was setup but you might want to check the README under
/opt/kde/share/apps/lisa/README and the documentation under
/opt/kde/share/doc/HTML/<language code>
/lisa (It can also befound somewhere inside KDE help). I'm sorry I couldn't be more specific on this one, but I can't remember how to configure it.
Now, your samba error (if I understood correctly) means that you don't have a
/etc/samba/smb.conf file, it is usually not fatal but annoying.
You could either copy the provided example
/etc/samba/smb.conf-sample and modify it to fit your needs or create one from the void using a text editor or use SWAT to have a nice HTTP tool to configure samba for you.
If you want to use SWAT, you have to edit /etc/inetd.conf and uncomment the line which reads
Code:
#swat stream tcp nowait.400 root /usr/sbin/swat swat
and restart inetd
Code:
#/etc/rc.d/rc.inetd restart
or
#killall -HUP inetd
and connect your favourite browser to
http://localhost:901/
Note: You don't need Lisa to explore a Samba network, you can just use press ALT+F2 under KDE and write
as uselpa suggested, and you should be able to browse Samba properly. You DO need to have Samba configured in you network though, but not in your machine.
