pppd vs isdn

[Rybarik, Michal]

caute,
 
uz som vyriesil problem s pripojenim externeho ISDN modemu, vdaka za vsetky hints. mgetty dvihne
incoming ISDN data call, rozpozna ppp spojenie a spusti pppd. avsak tu sa nepohodnu:
 
Mar 14 19:04:30 ftp pppd[14065]: pppd 2.4.1 started by a_ppp, uid 0
Mar 14 19:04:30 ftp pppd[14065]: Using interface ppp0
Mar 14 19:04:30 ftp pppd[14065]: Connect: ppp0 <--> /dev/ttyS0
Mar 14 19:04:30 ftp /etc/hotplug/net.agent: assuming ppp0 is already up

potial je to ok... tu zacinaju problemy:
 
Mar 14 19:04:33 ftp modprobe: modprobe: Can't locate module ppp-compress-21
Mar 14 19:04:33 ftp modprobe: modprobe: Can't locate module ppp-compress-21

na toto mam riesenie, definovat v modules.conf aliasy, konkretne na toto treba
alias ppp-compress-21 bsd_comp
nasiel som to na nete vo viacerych zdrojoch, takze asi to pojde. vo vsetkych cudzich logoch ktore som videl, sa po tomto obe strany dohodli na ipckach a spojenie fungovalo, i ked nepouzivalo kompresiu. ale mne sa to nespoji, na klientovi ostane svietit hlaska o overovani hesla a skonci s chybou - odpojenie serverom, a na serveri je v logu
 
Mar 14 19:04:33 ftp pppd[14065]: Protocol-Reject for unsupported protocol 0x0
Mar 14 19:05:01 ftp last message repeated 7 times

was ist das? na nete som nasiel rozne rady, ale vzdy tam bolo nejake cislo protokolu (0x a 4 cifry), s tymto errorom som sa stretol iba raz, bolo to pri dial-oute, a dotycnemu poradili zmenit ISP... to je pruser, neviem co s tym a vymenit mozem podla tej rady len seba ;o) skusal som vypnut vsetky kompresie a ine finty na strane servera i win klienta, nic nepomohlo, nedohodnu sa. any idea?
