Salve, ho riscontrato alcuni problemi dovuti (credo) a NetworkManager:
Ho emerso applet-nm, pero' manca la gui da cui posso configurare tutti i parametri di connessione: IPv4, DNS, ecc... inoltre, ho i seguenti problemi.
| Code: | realnot@mars ~ $ ping google.com
ping: icmp open socket: Operation not permitted
realnot@mars ~ $ su
Password:
host330 realnot # service NetworkManager stop
* Stopping NetworkManager ... [ ok ]
host330 realnot # ping google.com
ping: unknown host google.com
host330 realnot # exit
exit
realnot@mars ~ $ su
Password:
mars realnot # ifconfig

Qualcuno saprebbe dirmi a cosa son dovuti e come risolverli?
EDIT 1:
Da utente normale non riesco a pingare: ping: icmp open socket: Operation not permitted e non riesco nemmeno ad aprire un qualsiasi programma come konsole, konquerror, ecc. Disabilitando NetworkManager, posso lanciare qualsiasi proramma, ma non riesco a connettermi (ovviamente). Quando uso il comando "su" con NetworkManager attivo, mi loggo con hostname = host330, se invece NM e' disabilitato, ottengo un root login normale.

leggendo il primo link elencato da goggle, sembrerebbe dipendere da una impostazione impropria delle capabilities.
può essere che tu abbia compilato il pacchetto senza le use flag caps o filecap (e in questo caso credo che tu debba modificare i privilegi del tuo file con suid).
vedi anche man capabilities.

Il cambio di hostname è un problema legato al client dhcp (non so se usi dhclient o dhcpcd), configuralo in modo tale che non ti cambi l'hostname.
Il cambio di hostname sicuramente ti creerà grossissimi problemi con tutti i programmi, soprattutto quelli di KDE.
