Subject: ADSL connection problem
To: [EMAIL PROTECTED]
Cc: [EMAIL PROTECTED]

This is a classic chicken-and-egg problem. I've got a problem with my ADSL
connection, so can't write this from home. On the other hand, from work, I
have no access to Gmail or to the mailing-list, so I won't be able to see if
anyone answers me.

Therefore, if anyone can help, please CC to my work address -
[EMAIL PROTECTED] - although, I'm not sure the content filter will allow
the messages through :-(

I apologize that I may not provide enough info, since I'm not at my computer
and don't have access during the day. But I'll be happy to provide any
additional info requested.

First some background history - I've been connected to ADSL on Mandriva
(currently 2007.0) for years with no problems. My ISP is 015-Smile. The
first problem I ever had was 2 weeks ago and that turned out to be a problem
with a hardware component at the Bezeq side. Since then everything was back
to normal.

According to /var/log/syslog, my connection was up for about 3500 minutes
and went down on Saturday night (at 22:04). Since I have a script that
checks if I'm on-line at regular intervals, I was automatically re-connected
2 minutes later. Since then, I can't reach any sites on the Internet. I can
ping my local network and also can ping Internet addresses (for example
google or ynet) so I am connected and DNS is working. The output of ifconfig
seems normal. But any attempt to use a browser (I tried FF, Opera, Konqueror
and even lynx) or to send or receive e-mail (Kmail) fails. Ktorrent is also
dead. BTW - when I try to use a browser, I see the "normal" site contacted
message and there is some sort of exchange of data. For instance, when I
type www.ynet.co.il, the address bar shows
http://www.ynet.co.il/home/0,7340,L-8,00.html, so some sort of contact has
been made.

Since the problem started, syslog has been full of thousands of messages
like the following:

Jul 2 18:47:01 shlomo1 pptp[9910]: anon log[decaps_gre:pptp_gre.c:407]:
buffering packet 354(expecting 353, lost or reordered)

I contacted 015 and after being instructed to telnet into one of their
servers and succeeding (telnet 192.114.186.54 110) they said they had no
idea what to do (we don't support Linux). The only thing they suggested was
to lower mtu from 1452 to 1420. I tried but it made no difference. Actually,
I didn't really expect any change since I haven't changed the mtu for the
last 7 years and saw no reason for the change.

I called Bezeq and they claim the line is clean.

Although I don't really have any experience with nmap, I tried doing some
random scans of google and ynet and got lots of information, so I can again
say that I am connected to the Internet.

It occured to me that something may have changed on my system since I
regulary use urpmi to update the system. However, as an emergency recovery
measure,I have a second installation of Mandriva on a different partition
(and have never done any updates so nothing has changed in over a year). I
tried booting from that partition and the results were the same as on my
regular partition.

I should mention that I don't have Windows, so I can't say if this problem
is Linux only.

As I mentioned before, please CC to [EMAIL PROTECTED]


TIA
