Zdravim vespolek,
nejaky cas jsem naprosto bez problemu pouzival mpd na vytvoreni tunelu 
ze vzdaleneho pocitace. Nicmene najednou (netusim, co jsem kde zmenil) 
se zacal mpd chovat podivne:
pokud jej spustim jako daemon, vzdaleny stroj se pripoji, nicmene 
neprida se zaznam do arp tabulky a bez nej je ten tunel tak akorat do 
toho jednoho stroje.
pokud spustim mpd interaktivne, vzdaleny stroj se vubec nepripoji!

V konfiguraci mpd jsem nic nemenil, v konfiguraci firewallu jsem rovnez 
nic podstatného nemenil. Nechapu, proc se jednou vzdaleny pocitac 
pripoji a podruhe ne.

Netusite nahodou nekdo, proc k tomu dochazi?

pripojuju conf. mpd, typescript z neuspesneho pokusu o pripojeni k mpd 
(typescript z uspesneho jaksi nevim, jak ziskat - uspesne se prihlasi 
pouze pri spusteni jako daemon) a tcpdump z uspesneho i neuspesneho 
pokusu o prihlaseni.:

mpd.conf:
=========

default:
	load pptp

pptp:
	new -i ng0 pptp pptp
	set iface disable on-demand
