I have several computer systems running FreeBSD 2.2.2-RELEASE on a network using the User PPP from this release. (This system has been very stable, congratulations to all involved). I have a problem when connecting 2 computers via a modem with User PPP running on both ends. The problem is that after a period of time, usually days, the connection will slow down. Ping times from one system to the other are as follows: 64 bytes from 192.168.1.1 icmp_seq=1 ttl=255 time=5841.774 ms 64 bytes from 192.168.1.1 icmp_seq=2 ttl=255 time=4870.321 ms 64 bytes from 192.168.1.1 icmp_seq=3 ttl=255 time=3861.174 ms 64 bytes from 192.168.1.1 icmp_seq=4 ttl=255 time=2860.197 ms 64 bytes from 192.168.1.1 icmp_seq=5 ttl=255 time=1860.253 ms 64 bytes from 192.168.1.1 icmp_seq=6 ttl=255 time=851.134 ms 64 bytes from 192.168.1.1 icmp_seq=7 ttl=255 time=120.262 ms The fix is close the PPP connection and to redial, ie: PPP on > close ppp on > dial The connection now works at 150 ms. I have 2 seperate sets of systems that exhibit the same problem. I am using User PPP to connect to my ISP, this link is fine with no problems. I also have 2 computers connected the same as the above, but using a serial cable instead of a modem, this link is fine. The logs show nothing except in ppp.tun0.log I see: HDLC errors -> FCS: 1 ADDR: 0 COMD: 0 PROTO: 0 but this entry is dated at the time of connection not at the time of the problem. Has anyone seen the above problem before, or could someone please give some tips on how to find the cause of the problem. Thanks in advance for any help.
