I have a machine in the garage that I use to try out the new stuff (kde4) Getting my home LAN to work has always been a chore for me, but I usually get it to work. Not so under kde4. Try as I might I am unable to make the Garage machine visible to the rest of the network, altho I can see my other machines from it. [His and Her(winXP) desktops, His and Her(winXP) laptops.] Under kde3.5 my garage machine was perfectly visible and writable to from my Desktop.
The missing link seems to be that under 3.5 there is a samba configuration utility under the ControlCenter>Internet>Samba that I can use to help configure my network. Under kde4 this configuration is GONE. My smb.conf file in kde4 seems to say what it does under kde3.5. browseable=yes, guest=OK, writable=yes, public=yes.
Under kde3.5 i remember having to install kde-networks to make the CC>Internet>Samba item usable. I don't find this with the kde4 section enabled in my synaptic. I am at a loss as to what to try next. All machines are fully undated from my PASS account.
