Xelayb:
PCs and DB are all connected to the same 10/100 ethernet switch, then the uplink of this switch connected to a WIFi AP in client mode, which connect my small home wired LAN to the ADSL router and the Internet. I haven't notice any connectivity problem with the other three PCs in two years. In fact, I have tried to download the SAME URL that the Dreambox is trying to get from another PC, at the SAME moment, and the file reachs the PC in a few seconds, while the Dreambox stays stuck.
Attached to this reply are two ethereal captures: "wget_a_remote_url.zip" is the traffic captured when the dreambox (192.168.1.31) tried to download a new control panel for the hydra image. Yo can see that the HTTP GET command is issued, then the remote server replied with TCP ACK, but the HTPP 200 OK reply never comes.
The second capture is "wget_a_local_webpage"; for this, I have manually entered a "wget" command in the dreambox to retrieve the index.html page located in a local web server (actually, the web server of Emule in the PC at home, 192.168.1.4 -DB IP address is 192.168.1.31 as before-) . In this case, everything is OK!!!!!
Then, I have tried to download a web page of my ISP (
www.ya.com), from the DB, and it works also!, so I cannot blame the ADSL ruoter or some other equipment of my own.
I don't know what to think. Today, I bet for a Time-to-live-like problem, but not of the IP protocol but of the linux HTTP protocol implementation. But, surely, there is no a TTL equivalent at the HTTP protocol level, so....
Anyway, thanks for your help. I keep thinking...
