pppd se nekdy znova nechytne

[Zdeněk Böhm]

Ahoj,

pro komunikaci mezi notebookem a serverem pouzivam pppd, ktery honim pres
infraporty. Spojeni nahazuju temito dvema skripty:

--- nejprve na strane serveru ---
#!/bin/sh
/usr/sbin/irattach /dev/ttyS1 -s
/usr/sbin/pppd /dev/ircomm0 115200 192.168.100.1:192.168.100.2 passive
persist noauth lock linkname irda

--- potom na strane notebooku ---
#!/bin/sh
/usr/sbin/irattach /dev/ttyS1 -s
/usr/sbin/pppd /dev/ircomm0 115200 persist defaultroute noauth lock linkname
irda

pri praci se obcas stane, ze infra ztrati spojeni. Ne proto, ze by tam byla
nejaka chyba, ale clovek se treba v betli moc mrvi a perinou zakryje cidlo
na notebooku :-)) Pridal jsem proto pri spousteni pppd parametr persist,
ktery by mel zarucit, ze po ztrate spojeni pppd neumre, ale pokusi se
spojeni znovu navazat. Ono to funguje, ale uspesnost je bohuzel jen takovych
40%. V praxi to vypada tak, ze po ztrate spojeni (infra) a jeho obnoveni
pppd spojeni obcas nabehne a obcas uz ne. Na obou pocitacich sice pppd porad
bezi, ale uz se nejak nedomluvi s protejskem. Musim na obou pocitacich pppd
shodit a nahodit znova. Toho bych se rad zbavil. Mate, prosim, nekdo nejaky
napad, kde muze byt chyba?

P.S. Zkousel jsem spoustet pppd i s parametrem debug, ale ani tak jsem v
logu zadne podezrele hlasky nenasel. Odpovidajici kus logu (z notebooku, po
pouziti debug) prikladam:
