2018-01-25 Building a testing server for pppoe
The new homeserver will have to run the same pppoe client setup as the current server. But I want to get the whole setup tested before the migration to minimize disruption. Since I'm not going to get a free extra vdsl line and vdsl modem to test with and the complicated part is in the pppoe and ppp client part I decided to use a test vlan and set up a pppoe-server and ppp server on that vlan. The pppoe server part is started with# pppoe-server -I eth0.99 -C kzdoos -L 172.16.19.1 -R 172.16.21.19And it's indeed available from the client:# pppoe-discovery -I eth2 Access-Concentrator: kzdoos Got a cookie: 84 39 c6 51 13 fe 32 00 2c 06 2a b4 38 0e 30 87 46 7b 00 00 -------------------------------------------------- AC-Ethernet-Address: 00:1f:c6:59:76:f6So that part works. Next is to get an actual ppp session working over it. The server part was a bit of work as I want to get the whole configuration including password checks. Server configuration in /etc/ppp/pppoe-server-options on the server system:require-pap lcp-echo-interval 10 lcp-echo-failure 2 hide-password noipx ipv6 ,And the client configuration in /etc/ppp/peers/dray-vdsl:user testkees password topsecret +pap noauth noipdefault ipv6 , ipv6cp-use-persistent defaultroute persist maxfail 0 noproxyarp ipparam xs4all lcp-echo-interval 10 lcp-echo-failure 6 pty "pppoe -I eth2"Lots of options to make the setup exactly the same as the current. It took a lot of tries before password authentication was working. I could not get the client-side password in /etc/ppp/pap-secrets to work, but as show above the password in the ppp configuration did work. And the setup in /etc/network/interfaces on the client just the same as the known configuration:iface pppdray inet ppp provider dray-vdslAnd it works!# ifup pppdray Plugin rp-pppoe.so loaded. # ifconfig ppp0 ppp0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1492 inet 172.16.21.45 netmask 255.255.255.255 destination 172.16.19.1 inet6 fe80::5254:ff:fe3c:2014 prefixlen 10 scopeid 0x20<link> ppp txqueuelen 3 (Point-to-Point Protocol) RX packets 9 bytes 252 (252.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 9 bytes 202 (202.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 # ping -c 3 172.16.19.1 PING 172.16.19.1 (172.16.19.1) 56(84) bytes of data. 64 bytes from 172.16.19.1: icmp_seq=1 ttl=64 time=0.721 ms 64 bytes from 172.16.19.1: icmp_seq=2 ttl=64 time=0.436 ms 64 bytes from 172.16.19.1: icmp_seq=3 ttl=64 time=0.449 ms --- 172.16.19.1 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2029ms rtt min/avg/max/mdev = 0.436/0.535/0.721/0.132 msThe mtu is not yet what I want, but the session is alive.
