Hi, working with the new 3.1.1b2 release.
I am working with the floppy image in a pretty near-to-defaults setup,
just to try to get the pppd working (PPPoE actually).
I'm having trouble getting the pppd to behave - in the syslog I'm
seeing, every time I try to cause a PPPoE connection, my attempt ending
with:
Mar 29 12:55:54 firewall pppd[618]: Local IP address changed to
69.196.xxx.yyy
Mar 29 12:55:54 firewall pppd[618]: Remote IP address changed to
206.248.xxx.yyy
Mar 29 12:55:54 firewall pppd[618]: Fatal signal 11
[...]
So I wonder first, is anyone else successfully using pppd (PPPoE) under
BuC 3.1.1b2?
And does this 'Fatal signal 11' indicate maybe a problem with the
executable, or compile options?
I have no idea; but I'm running pppd and pppoe without pb's.
Ok, thx for the feedback - it looks like me or my setup?!
From where do you get the 10.x adresses?
They seem to be what pppd assigns as the defa...@startup ip address if
the ppp connection is a demand connection, until pppd has received an
IP addy from upstream.

Let me update on my testing:
- I had some bad/missing settings for my PPP setup that seemed to be the
cause of all of my grief *except* Fatal signal 11.
- pppd tip: include the option:
dump
in dsl-provider file and in one of the logfiles you'll get pppd's
interpretation of what options it's seeing (it seeks options from a few
files and identifies which options from which files). This is how I came
to observe the difference between my old, working 3.0b2 setup, versus
this new one.
- pppd tip: do that logging of the 'dump'ed options from within the
init-invoked pppd (i.e. don't use 'pppd call dsl-provider' from the
shell to see what options are active - I noticed discrepancies in the
listed options depending on how pppd was being invoked).
- pppd tip: In 3.0b2 some of my options that were placed in the 'ppp'
options file (/etc/ppp/options) did not get recognized under 3.1.1b2 so
I had to move them to the pppoe options file (/etc/ppp/peers/provider)
to get respect?!?!
So what I have now is an identical set of pppd options in my testing of
3.1.1b2 as to my working 3.0b2 and I still have one showstopper prob
left, the Fatal signal 11.
My LCP IPCP transactions all happen nice (PAD*, IPCP reqs, acks, naks)
and I get assigned proper ip addy for dns1, dns2, my_ip and remote_ip,
then boom. From ppp.log:
Mar 30 11:18:14 fw pppd[631]: local IP address 206.248.xxx.yyy
Mar 30 11:18:14 fw pppd[631]: remote IP address 206.248.xxx.yyy
Mar 30 11:18:14 fw pppd[631]: primary DNS address 206.248.154. 22
Mar 30 11:18:14 fw pppd[631]: secondary DNS address 206.248.154.170
Mar 30 11:18:14 fw pppd[631]: Fatal signal 11
Mar 30 11:18:14 fw pppd[631]: Exit.
Noticeably absent is the 2 lines that should follow the 2ndary DNS line,
which under 3.0b2 says:
Mar 30 09:30:29 R11 pppd[5793]: Script /etc/ppp/ip-up started
(pid 25879)
Mar 30 09:30:32 R11 pppd[5793]: Script /etc/ppp/ip-up finished
(pid 25879), status = 0x0
In the pppd code, this is a wee walk between the line of code for the
2ndary DNS and the line of code for launching of the etc/ppp/ip-up
script where normally I would next see a log entry:
if (go-dnsaddr[0])
notice(primary DNS address %I, go-dnsaddr[0]);
if (go-dnsaddr[1])
notice(secondary DNS address %I, go-dnsaddr[1]);
}
reset_link_stats(f-unit);
np_up(f-unit, PPP_IP);
ipcp_is_up = 1;
notify(ip_up_notifier, 0);
if (ip_up_hook)
ip_up_hook();
/*
* Execute the ip-up script, like this:
* /etc/ppp/ip-up interface tty speed local-IP remote-IP
*/
if (ipcp_script_state == s_down ipcp_script_pid == 0) {
ipcp_script_state = s_up;
ipcp_script(_PATH_IPUP, 0);
}
}
- per the pppd code, the 'Fatal signal 11' /is/ in fact a SIGSEGV exception.
