Bug 158905 – coreutils-6.7 fails to submit correct username for PPP connexions in CHAP challenge response

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Patrice Bouvard 2006-12-23 05:02:44 UTC]

Hi !

I have a DSL connexion at home and I use PPPoE protocol.
Here is my /etc/conf.d/net relevant part :

config_ppp0=("ppp")
link_ppp0="br0"
plugins_ppp0=("pppoe")
username_ppp0="[e-mail]"  ## my correct username
password_ppp0="SECRET"
pppd_ppp0=(
       "lock"
       "updetach"
       "debug" ## added for debug in /var/log/messages
       "noauth"
       "defaultroute"
       "lcp-echo-interval 10"
       "lcp-echo-failure 10"
       "holdoff 4"
)


With coreutils-6.6, everything works fine, here are the messages in /var/log/messages :

Dec 23 13:49:09 framboise pppd[20244]: Connect: ppp0 <--> br0
Dec 23 13:49:09 framboise pppd[20244]: sent [LCP ConfReq id=0x1 <mru 1492> <magic 0xcf7384d6>]

Dec 23 13:49:10 framboise pppd[20244]: rcvd [CHAP Success id=0x1 "CHAP authentication success, unit 21971"]



Then, I upgraded my system and my PPPoE connexion broke (and it took me a while to figure that the new coreutils version was the problem). Here is the problem with coreutils-6.7 :

Dec 23 13:48:40 framboise pppd[5176]: sent [LCP EchoReq id=0x0 magic=0xf751125f]
Dec 23 13:48:40 framboise pppd[5176]: rcvd [CHAP Challenge id=0x1 <75c1e5040429de5b73ab33727089ccdc>, name = "BAS-ROGIER"]
Dec 23 13:48:40 framboise pppd[5176]: sent [CHAP Response id=0x1 <98d7ba8e8009ffd15a52da2c7655c41f>, name = "framboise"]
Dec 23 13:48:41 framboise pppd[5176]: rcvd [CHAP Failure id=0x1 "Login failed"]



As you can see, my box provides the name "framboise" which is the hostname of the box. It should be providing my ISP the name "[e-mail]" which is set in /etc/conf.d/net

My solution was to revert back to coreutils-6.6

coreutils shouldn't be the problem here. CC's net-dialup for ideas

[Comment 4 Alin Năstac (RETIRED) 2007-01-03 15:02:26 UTC]

It is an akward malfunction, for which I currently have no explanation. I will test it myself as soon as possible.

[Comment 5 Alin Năstac (RETIRED) 2007-01-04 14:01:18 UTC]

I've verified pppd authentication on an amd64 system with coreutils-6.7-r1. It works as expected.

Please post here the pppd command line (the output of "ps -ef | grep pppd"). I suspect you'll have "user framboise" instead "user [e-mail]".

I don't know if the bug still exists with recent coreutils... today I've got coreutils-6.4 (I've got a mask on >sys-apps/coreutils-6.6 since I reported this bug).

But I can tell you, I am pretty sure that at the time, the pppd command line was "user framboise" with coreutils-6.7 and it was "user [e-mail]" with coreutils-6.6.

It is "user [e-mail]" with coreutils-6.4.

I will try to remove the mask and try the latest ~x86 coreutils version

Looks like coreutils-6.9 works fine !
