I don't know how much help this is, but I do exactly the same thing and have no problems with the SSH link interfering with the ADSL link. Are you running out of tun devices? (Or are they auto-cloned now?) Responsible Changed From-To: freebsd-bugs->brian Assign to brian as he the ppp master. State Changed From-To: open->closed No feedback from the originator. I find it bizarre that this would happen, and then resolve itself when the two processes are restarted. The only way two ppp instances can affect eachother is if they end up with duplicate endpoint discriminators in multilink mode. Here it seems as if both processes are getting the same tun descriptor, but that shouldn't be possible. If the problem still persists, please let me know and supply the requested logs. |
I need to have two tunnel devices. One is for internet connection, wich is PPPoE, the other one is for a PPPoSSH session - to connect to my company via a VPN. During startup, I enabled ppp to dial to Internet in the rc.conf script. # PPPoE for DSL ppp_enable=YES ppp_mode=ddial ppp_nat="no" ppp_profile="arcor-dsl" ppp_user="root" When I want to connect to my company I simply start ppp. PPP then answers with an error message which kills my PPPoE session to the Internet. The error messages logged by /var/log/messages Aug 20 17:23:40 circa ppp[935]: Error: bundle_Create: ioctl(TUNSIFMODE): Device busy Aug 20 17:23:45 circa ppp[225]: tun0: Error: ip_Input: deflink: wrote 56, got 0 Aug 20 17:23:47 circa last message repeated 3 times Aug 20 17:23:47 circa ppp[225]: tun0: Warning: iface rm: ioctl(SIOCDIFADDR, 213.23.24.183 -> 145.253.4.4): Can't assign reques ted address I then have to kill my ppp, start the internet again and then open the PPPoSSH session. After the first fail, everything is fine. So I have to go through this procedure only once - just after reboot. Fix: Okay, here are the commands from the shell ppp quit ps ax|grep ppp 941 ??
