It seems that there is a problem with /dev/i4brbch0 when using i4bppprun provided with i4b because ppp always looses the connection to the device. Mar 18 18:09:25 lisa ppp[2420]: IPCP: deflink: State change Closed --> Req-Sent Mar 18 18:09:25 lisa ppp[2420]: Error: DoLoop: select(): Bad file descriptor Mar 18 18:09:25 lisa ppp[2420]: IPCP: deflink: SendTerminateReq(1) state = Req-Sent Mar 18 18:09:25 lisa ppp[2420]: IPCP: deflink: State change Req-Sent --> Closing Mar 18 18:09:25 lisa ppp[2420]: Error: Oops, destroying a datalink in state open Mar 18 18:09:25 lisa ppp[2420]: Error: ID0logout: No longer logged in on i4brbch I remade the device and tried a lot of other things but nothing helped. Therefore I decided to switch to a bash-script executing: "/usr/sbin/ppp -direct inc_rbch0 <>/dev/i4brbch0" I first tried using /bin/sh but it seems that sh is not redirecting STDIN and STDOUT at the same time. I could always see the PAP-requests of my site but the remote end didn't answer (Well, probably the remote end answered but the answer wasn't redirected to STDIN of ppp). If you want to try my configuration, you should compile bash2 from the ports and use the following bash-script: /etc/isdn/i4brunppp -------------------------------------------------------------------- #! /usr/local/bin/bash /usr/sbin/ppp -direct inc_rbch0 <>/dev/i4brbch0 -------------------------------------------------------------------- Put it into /etc/isdn/ and name it i4brunppp. Don't forget to set execute-rights. Then you have to edit /etc/isdn/isdnd.rc to suite your needs. Here is my configuration file: /etc/isdn/isdnd.rc -------------------------------------------------------------------- system # Accounting acctall = on acctfile = /var/log/isdnd.acct useacctfile = yes isdntime = on # Monitor-Access - disabled monitor-allowed = no monitor-port = 451 monitor = "/var/run/isdn-monitor" monitor-access = fullcmd monitor-access = channelstate, logevents monitor-access = callin, callout monitor = "10.10.10.0/24" monitor-access = restrictedcmd, channelstate, callin, callout regexpr = "DIALIN.*call active" regprog = i4brunppp # MAIL settings in case of errors mailer = "/usr/bin/mail" mailto = "root" rtprio = 25 entry name = DIALIN isdncontroller = 0 isdnchannel = -1 usrdevicename = rbch usrdeviceunit = 0 local-phone-dialout = <yourdialout#> local-phone-incoming = <yourdialin#> remote-phone-dialout = 0 remote-phone-incoming = * b1protocol = hdlc dialin-reaction = accept dialout-type = normal direction = in idletime-incoming = 300 ratetype = 0 unitlength = 0 unitlengthsrc = conf -------------------------------------------------------------- Don't forget to replace <yourdialout#> and <yourdialin#> with your local settings. Now you have to edit your ppp.conf in /etc/ppp/ppp.conf Here is mine: /etc/ppp/ppp.conf -------------------------------------------------------------- inc_rbch0: set log CCP Command IPCP LCP enable pap set ifaddr 10.10.40.1 10.10.40.11 set timeout 60 set dial set login set hangup set device /dev/i4brbch0 set speed sync accept dns set dns 10.10.10.1 # disable pred1 # disable passwdauth # disable deflate # disable protocomp # disable vjcomp # # deny acfcomp # deny deflate # deny pred1 # deny protocomp # deny vjcomp -------------------------------------------------------------- This is just the dialin part of my ppp.conf file. You have to replace "set ifaddr" and "set dns" with your local settings. If you change the name of your dialin-config from "inc_rbch0" to something else, you have to change the bash-script too !!!! Uncomment the "disable" and "deny" settings if your clients have problems connecting. I had a Win95 client which didn't like VanJacobsen Compression (vjcomp). You have to poke arround with the settings a bit. Windows 98 and NT 2000 clients don't have these problems. If you want dialout too, then you have to create another entry with your dialout settings. You shouldn't label this entry "default". Use another name (i.e. dialout). If you want dialout on demand you can use the following rc.conf settings: /etc/rc.conf ------------------------------------------------------------- ppp_enable="YES" ppp_mode="auto" ppp_nat="YES" ppp_profile="<yourdialoutlabel>" ppp_user="root" ------------------------------------------------------------- Replace <yourdialoutlabel> with your dialout label from /etc/ppp/ppp.conf. If you don't want NAT then replace ppp_nat="YES" with ppp_nat="NO" Test your dialout-config NOW! If your dialout config doesn't work go to http://www.freebsd.org/ and have a look at the documentation. There is lots of documentation for dialout configs. Last but not least you have to edit /etc/ppp/ppp.secret and put your dialin logins and passwords in there. /etc/ppp/ppp.secret example ------------------------------------------------------------- login1 password1 login2 password2 ------------------------------------------------------------- You can do a lot with this file (i.e. assign a specific IP to a specific user). Read the docs if you need such features. That's it. Assuming your local isdn configuration is done correctly and you started isdnd, you should now be able to dialin. You can start isdnd i.e. using: ------------------------------------------------------------- isdn_enable="YES" isdn_fsdev="/dev/ttyv8" isdn_flags="-dn -d0x1f9" ------------------------------------------------------------- in /etc/rc.conf Things you have to watch out for if your dialin still doesn't work: - Check your ISDN configuration. Try to DIALOUT to an ISP only using i4b. If this works, your isdn configuration seems to be correct. - Increase logging of isdnd and ppp. - Is the name of the dialin-label in /etc/isdn/i4brunppp the same as in /etc/ppp/ppp.conf? - If you use dialout at the same time - do you have a second tun device configured in your kernel config. Finally here is my kernel config file. Watch Out! You cannot just append these settings to your config file. You have to change them to suite your needs!!!! --------------------------------------------------------------- # I want NAT, but no firewall => default_to_accept options IPFIREWALL options IPFIREWALL_DEFAULT_TO_ACCEPT options IPDIVERT # You need these settings for dialin pseudo-device ppp 2 pseudo-device tun 2 # You want compression? Include those settings. options PPP_BSDCOMP options PPP_DEFLATE # You need bpf too, if you want to use it. options PPP_FILTER # That's my ISDN card. Change this to yours. options "AVM_A1_PCI" device isic0 # ISDN settings. Change them to your needs. You # probably need most of them. pseudo-device "i4bq921" pseudo-device "i4bq931" pseudo-device "i4b" pseudo-device "i4btrc" 4 pseudo-device "i4bctl" pseudo-device "i4brbch" 4 pseudo-device "i4bipr" 4 options IPR_VJ pseudo-device "i4bisppp" 2 pseudo-device sppp ----------------------------------------------------------------- You don't need all of those settings. It depends on your local needs. Hope this helps. Greetins, Alex To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
