Perhaps a clue, I made a null-modem cable and captured the boot sequence. With all 3 eths connected to switches (to make link appear). The boot-up shows:
===========================SNIP================================= Setting kernel variables ... net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.all.rp_filter = 1 ... done. Mounting local file systems... Configuring network interfaces: Error: either "local" is duplicate, or "/24" is a garbage. eth0: link up. eth0: Setting full-duplex based on negotiated link capability. RTNETLINK answers: Network is unreachable eth1: link up. eth1: Setting full-duplex based on negotiated link capability. eth2: link up. eth2: Setting full-duplex based on negotiated link capability. done. ==========================SNIP================================== And (on the leaf box via ssh): ip a 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff 3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0d:b9:00:d9:64 brd ff:ff:ff:ff:ff:ff 4: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0d:b9:00:d9:65 brd ff:ff:ff:ff:ff:ff inet 192.168.42.254/24 brd 192.168.42.255 scope global eth1 5: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0d:b9:00:d9:66 brd ff:ff:ff:ff:ff:ff inet 172.21.42.254/24 brd 172.21.42.255 scope global eth2 I don't know where the error message originates, but it seems to point at misconfiguration of eth0 (i.e. my problem). What are the minimum packages I must load to get a running box that routes (no shorewall, iptables etc)? Maybe I can start there and add packages?
