A question to the MTU gurus (Muli/Dani?): I'm pretty sure I have an MTU problem. However, I can't figure out: A. How to 'debug' it (i.e. I don't know if the problem is really MTU) B. What the problem is (if it exists).
I think that (A) is especially important, since I'm getting the feeling I'm chasing ghosts; The symptoms are as follows: I'm have an excellent ADSL connection, but connecting to certain servers using timeout-sensitive protocols I am having problems. For example, when trying to upload files to my FTP server, either using FTP or SSH + rz, the connection takes forever and breaks up in the middle quite frequently. Pinging the server shows that my packet loss is negligible and that the connection is fast (~35ms, <1% packet loss). Other people can FTP with no problems. I have no other problems with that server or with my Internet connection in general (i.e SMTP, HTTP all work quite nicely). The only think I can think of is some strange MTU problem. For example, trying to FTP from my linux connection (the one connected to an ADSL) via FTP fails miserably with timeouts. The connection is done directly, so it's not a masquerading problem. Now the facts: The MTU on the ppp0 interface is: 1452 The MTU on the eth1 interface (the one connected to the ADSL modem) is: 1500 as far as I can tell from the how-to, that should be the right values. Any idea how I can debug it and/or fix the problem?
