Vazene kolegyne ,vazeni kolegovai!
Havarovali mi jeden z dvoch kanalov RIADu na Xhoste s Ubuntu. Na tych diskom som mal adresare
/boot
/home
/opt
/srv
/usr/src
/tmp
/var
a
swap
ako samostatne oddiely
Vypadok bol nevrtany, v cvase instalacie isiel len 1 ks disku z 4 moznych,
System sa mi podarilo dostat do stavu, ze funguje vsteko vratene exportu /home cez nfs, aj ked zo stratou udajov, ale bezi..
Jedina vec, ktora nefunguje je Xdmcp prihlasovania terminalov vdaka xdm. Po dlhom skumani som prisiel na to, ze na porte 177
ostavaju neprecitane data v Recv-Q. lsoff je nejaky cely podivny a ldd ma nakopone len na prekontrolovanie PAMu, to som ale robil a nic som nenasiel v minulosti. - nejake doinstaloacie medzi tyum boli. Vedel by mi nuiekto poradit, ako tak zdebugovat...
netstat -a|egrep xdm
