Log Stdout #31

I compiled rp-pppoe version 4 against pppd version 2.5.0 and I'm encountering issues with the client connection. The log output is not clear about the exact problem. Here's an example:

pppoe-server[107684]: Session 33 created for client bc:24:11:04:cf:a9 (100.103.0.36) on ens18 using Service-Name '' pppd[107684]: Plugin /etc/ppp/plugins/rp-pppoe.so loaded. pppd[107684]: RP-PPPoE plugin version 4.0 compiled against pppd 2.5.0 pppd[107684]: Plugin /usr/local/lib/pppd/2.5.0/radius.so loaded. pppd[107684]: RADIUS plugin initialized. pppd[107684]: Plugin /usr/local/lib/pppd/2.5.0/radattr.so loaded. pppd[107684]: RADATTR plugin initialized. pppd[107684]: pppd 2.5.0 started by root, uid 0 pppd[107684]: Connected to bc:24:11:04:cf:a9 via interface ens18 pppd[107684]: using channel 128 pppd[107684]: Using interface ppp0 pppd[107684]: Connect: ppp0 <--> ens18 pppd[107684]: sent [LCP ConfReq id=0x1 <mru 1492> <magic 0x74c2651a>] pppd[107684]: rcvd [LCP ConfAck id=0x1 <mru 1492> <magic 0x74c2651a>] pppd[107684]: rcvd [LCP ConfReq id=0x1 <mru 1492> <magic 0xa2569440>] pppd[107684]: sent [LCP ConfAck id=0x1 <mru 1492> <magic 0xa2569440>] pppd[107684]: sent [LCP EchoReq id=0x0 magic=0x74c2651a] pppd[107684]: rcvd [LCP EchoReq id=0x0 magic=0xa2569440] pppd[107684]: sent [LCP EchoRep id=0x0 magic=0x74c2651a] pppd[107684]: rcvd [PAP AuthReq id=0x1 user="0511774" password=] pppd[107684]: sent [PAP AuthNak id=0x1 "RADIUS: Can't read config file /etc/radcli/radiusclient.conf"] pppd[107684]: PAP peer authentication failed for 0511774 pppd[107684]: sent [LCP TermReq id=0x2 "Authentication failed"] pppd[107684]: rcvd [LCP EchoRep id=0x0 magic=0xa2569440] pppd[107684]: rcvd [LCP TermReq id=0x2 "Failed to authenticate ourselves to peer"] pppd[107684]: sent [LCP TermAck id=0x2] pppd[107684]: rcvd [LCP TermAck id=0x2] pppd[107684]: Connection terminated. pppd[107684]: Fatal signal 11 pppoe-server[23464]: Session 33 closed for client bc:24:11:04:cf:a9 (100.103.0.36) on ens18 pppoe-server[23464]: Sent PADT

Especially in this section:

pppd[107684]: sent [PAP AuthNak id=0x1 "RADIUS: Can't read config file /etc/radcli/radiusclient.conf"]

I believe it might be related to a dictionary attribute, but it's not reporting as previous versions did.

The pppd package is not clearly indicating where the error is occurring, making it difficult to diagnose the issue.

This isn't an rp-pppoe issue. It has to do with the RADIUS authentication plugin of pppd; you'll need to open the issue there. I suggest opening it at https://github.com/ppp-project/ppp

I know it's not pppoe, but this has already been fixed in ppp project in master. Gentoo carries a patch set which I highly recommend you apply locally, it includes various rather critical fixes, 2.5.0 should not be used in any production capacity in my personal opinion without those additional fixes.

Gentoo patchset at https://github.com/gentoo/gentoo/tree/master/net-dialup/ppp/files

You probably need/want everything starting with 2.5.0 in there (6 of them currently).
