Body
I have 2 local networks (2 offices connected with openvpn) Network 1: <pre><code>network 192.168.1.0/24 gateway 192.168.1.101 </code></pre> Network 2: <pre><code>network 192.168.2.0/24 gateway 192.168.2.10 </code></pre> in network 192.168.1.0/24 I have 2 servers - 192.168.1.180 and 192.168.1.183 first run on Debian 6 and second one on Archlinux (yes, I know it is bad choice for servers). I have no firewall on the servers. everything works fine, clients from 192.168.2.0 can connect to computers in 192.168.1.0 and back. Except one of servers - 192.168.1.180 (Archlinux). I can't connect to it and can't connect from it to any computer in 192.168.2.0. No ping, no traceroute. <pre><code>output from 192.168.1.180: route -n Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.1.101 0.0.0.0 UG 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 </code></pre> i run tcpdump on the gateway (192.168.1.101) and ping on 192.168.1.180 and get this: <pre><code>tcpdump src 192.168.1.180 listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 14:23:57.354061 arp who-has 172.19.155.1 tell 192.168.1.180 14:23:58.357354 arp who-has 172.19.155.1 tell 192.168.1.180 ... </code></pre> why it looks for 172.19.155.1? I don't know what this strange IP means. I have no networks like this, no GW, nothing. if I run ping on all other computer (for example ping from 192.168.1.183) I get: <pre><code>tcpdump icmp listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 14:29:36.834731 IP 192.168.1.183 > 192.168.2.10: ICMP echo request, id 3216, seq 1, length 64 14:29:36.956211 IP 192.168.2.10 > 192.168.1.183: ICMP echo reply, id 3216, seq 1, length 64 </code></pre> No one looks for this strange IP except 192.168.1.180. I cleaned arp table on 192.168.1.180 but nothing helps.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
