| hello,
|
| i'm using iijppp on a 2.1.0-RELEASE freebsd machine. occasionally,
| the ppp dialup becomes unusable; it connects and authenticates fine, but
| when packets are to be passed, nothing works. i've noticed that the
| routing table believes the slave side ip address is to be reached through
| the ethernet card (there's a specific entry for it), and the arp table
| contains an entry for it as incomplete. neither entry goes away. this
| seems to happen when another machine pings the ip address when the slave
| side isn't connected (i suspect any traffic would do it). the pinging
| machine (or atleast the one i tested) got an icmp redirect when it pinged.
| what i'd like to know is: (a) would using pppd solve this problem, (b)
| would upgrading to a later rev of free bsd solve this problem, or (c) is
| there something i am doing wrong? my ppp.conf follows. please direct any
| questions or replies direct to me as well as the list. thanks in advance.
I had this problem using pppd as well. Routes would hang around, and
arp-entries would hang around.
I made ip-up remove the route and the arp entry and re-add it. That works
for us because we had the auto-pap getty, which runs as root.
It's not exactly an elegant solution, but, it worked so I left it.
I haven't seen the same problems since upgrading to 2.2.2, although
now, I have a different set of problems to contend with.
