It's a LAN. Just a simple TP-Link router setup to do DHCP. No VLAN, no |

DMZ, only one subnet 192.168.0.0/24. It's at my apartment, so nothing fancy. |

Firewall is disabled on the server (CentOS) and my desktop. No special |
13 |
routing or bridging. |

DD-WRT is not very informative. It only has system-type stuff in |
19 |
/var/log/messages, nothing LAN-related. |

Capturing packets on my desktop shows strange behavior. When I ping my |
28 |
server (kwopper), my desktop (greenbeast) starts generating a bunch of |
29 |
ARPs, none of which get answered. When my laptop pings kwopper, the |
30 |
first ARP is answered instantly and the pings succeed. Pinging from |
31 |
kwopper is the same; instantly finds and connects to my laptop, but my |
32 |
desktop does not see any ARPs or ICMPs from kwopper. |

I can attach Wireshark dumps if helpful. tcpdump doesn't seem to want to |
35 |
work on my server for some reason. |
