I'm trying to establish VDSL connection using an ECI modem over PPPoE. I'm running OpenBSD 6.8 on APU board from PC Engines.
Relevant inerface configuration: /etc/hostname.em0 up /etc/hostname.pppoe0 inet 0.0.0.0 255.255.255.255 NONE mtu 1492 pppoedev em0 authproto chap authname 'my login' authkey 'my password' peerproto chap peerflag callin up dest 0.0.0.1 When I bring the interface up, I can see that it authenticates (tcpdump output is long so I put it below). I can observe that it authenticates and receives an IP address from the network ISP. However, when I check the interface, it does not set new IP and it is stuck with "no carrier":: pppoe0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1492 index 15 priority 0 llprio 3 dev: em0 state: initial sid: 0x0 PADI retries: 0 PADR retries: 0 groups: pppoe status: no carrier inet 0.0.0.1 --> 0.0.0.0 netmask 0xff000000 How can I further investigate this issue? I'm a bit out of ideas. Cheers, KN Here is the output from tcpdump -i em0, showing the exchange between my APU board and ECI VDSL modem. tcpdump: listening on em0, link-type EN10MB 01:19:24.111229 PPPoE-Discovery code Initiation, version 1, type 1, id 0x0000, length 12 tag Service-Name, length 0 tag Host-Uniq, length 4 #\324\311\274 01:19:24.117698 PPPoE-Discovery code Initiation, version 1, type 1, id 0x0000, length 12 tag Service-Name, length 0 tag Host-Uniq, length 4 #\324\311\274 01:19:24.122470 PPPoE-Discovery code Offer, version 1, type 1, id 0x0000, length 47 tag Service-Name, length 0 tag AC-Name, length 11 acc-aln4.fb tag Host-Uniq, length 4 #\324\311\274 tag AC-Cookie, length 16 8\236\305\331\324?\035s\227\256\274\320\373\012\374h 01:19:24.122653 PPPoE-Discovery code Request, version 1, type 1, id 0x0000, length 32 tag Service-Name, length 0 tag AC-Cookie, length 16 8\236\305\331\324?\035s\227\256\274\320\373\012\374h tag Host-Uniq, length 4 #\324\311\274 01:19:24.123960 PPPoE-Discovery code Initiation, version 1, type 1, id 0x0000, length 12 tag Service-Name, length 0 tag Host-Uniq, length 4 #\324\311\274 01:19:24.130257 PPPoE-Discovery code Initiation, version 1, type 1, id 0x0000, length 12 tag Service-Name, length 0 tag Host-Uniq, length 4 #\324\311\274 01:19:24.145508 PPPoE-Discovery code Offer, version 1, type 1, id 0x0000, length 47 tag Service-Name, length 0 tag AC-Name, length 11 acc-aln4.fb tag Host-Uniq, length 4 #\324\311\274 tag AC-Cookie, length 16 8\236\305\331\324?\035s\227\256\274\320\373\012\374h 01:19:24.145724 PPPoE-Discovery code Request, version 1, type 1, id 0x0000, length 32 tag Service-Name, length 0 tag AC-Cookie, length 16 8\236\305\331\324?\035s\227\256\274\320\373\012\374h tag Host-Uniq, length 4 #\324\311\274 01:19:24.149589 PPPoE-Discovery code Confirm, version 1, type 1, id 0x144e, length 12 tag Service-Name, length 0 tag Host-Uniq, length 4 #\324\311\274 01:19:24.149639 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 16 LCP Configure-Request Id=0x01: Magic-Number=2012867662 Max-Rx-Unit=1492 01:19:24.185026 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 21 LCP Configure-Request Id=0x1f: Max-Rx-Unit=1492 Auth-Prot=CHAP/MD5 Magic-Number=538534638 01:19:24.185062 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 21 LCP Configure-Ack Id=0x1f: Max-Rx-Unit=1492 Auth-Prot=CHAP/MD5 Magic-Number=538534638 01:19:24.185167 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 16 LCP Configure-Ack Id=0x01: Magic-Number=2012867662 Max-Rx-Unit=1492 01:19:24.188465 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 64 CHAP Challenge Id=0x01: Value=706d4498c8643102f0a75b6e8b352fcfa2fa51bd8ccd9177de4ca5a23a29aa2a966e425fd373e1441c3d32a7f161 Name=acc-aln4.fb 01:19:24.188546 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 44 CHAP Response Id=0x01: Value=803993c026af19d16f54c02c499865c0 Name=<***MY LOGIN***> 01:19:24.232859 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 33 CHAP Success Id=0x01: Message=CHAP authentication success 01:19:24.233293 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 6 LCP Terminate-Request Id=0x02: 01:19:24.233726 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 12 IPCP Configure-Request Id=0xfe: IP-Address=<IP ADDRESS FROM ISP> 01:19:24.236687 PPPoE-Session code Session, version 1, type 1, id 0x144e, length 6 LCP Terminate-Ack Id=0x02: 01:19:24.252350 PPPoE-Discovery code Terminate, version 1, type 1, id 0x144e, length 0 01:19:24.262382 PPPoE-Discovery code Terminate, version 1, type 1, id 0x144e, length 0 Best regards, Chris Narkiewicz -- +44 7502 415 180 (Phone, Signal, WhatsApp)
