Hello all!
I'm trying to get to work (or, to be more precise - to work properly)
ppp-server (pppd). Almost everything works fine, except one thing:
eventually (sometimes (but not always) after abnormal termination of modem
(PPP) connection - noisy lines), routing table on FreeBSD box gets wrong. It
says (among other lines):
#netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
...
my.ppp.client.addr link#2 UHLW 3 34
...
When it happens, pppd stops to work properly - modem answers; client
connects; logging in; getting IP address; - but can't even ping ppp server.
ARP table at this time doesn't contain such an entry for ppp client address:
#arp -a
...
? (my.ppp.client.addr) at (incomplete).
Following command returning everything to life:
#route delete my.ppp.client.address
My configuration:
1) FreeBSD 2.0.5. (yes, 2.0.5)
2) /etc/ppp/options:
crtscts
netmask 255.255.255.0
my.ppp.server.addr:my.ppp.client.addr
domain my.domain
passive
modem
proxyarp
3) pppd starts as shell (without any additional parameters)
4) relevant part of /etc/rc.serial:
modem() {
# Modem that supports CTS and perhaps RTS handshaking.
for i in $*
do
# may depend on modem
comcontrol /dev/ttyd$i dtrwait 100 drainwait 180
# Lock crtscts on.
# Speed reasonable for V42bis.
stty </dev/ttyid$i crtscts 57600
stty </dev/ttyld$i crtscts
stty </dev/cuaia$i crtscts 57600
stty </dev/cuala$i crtscts
done
}
...<skipped>...
modem 0
5) relevant line in /etc/ttys:
ttyd0 "/usr/libexec/getty std.38400" dialup on secure
I've browsed through all mail-lists archives I have looking for answer;
FAQs and Handbook; tried Altavista and DejaNews. No use by far :) Probably
I'm overlooking something obvious..
