Linux v.2.4.0 and Netscape 4.76?

Linux v.2.4.0 and Netscape 4.76?

[roger]

After making extensive enquiries elsewhere I have been advised to post
this question to the kernel mailing list. Joseph Anthony wrote recently
to the list about a similar matter (I think).

The problem: symptoms

It concerns the behaviour of Netscape after upgrading from kernel
2.2.16 to 2.4.0. With the new kernel Netscape locates and connects to
a URL, and sometimes begins to download, but then it just sits there
indefinitely (without downloading any data). This happens quite
consistently since I upgraded to 2.4.0 (about 2 weeks ago).  ppp,
telnet, ftp all function satisfactorily as far as I can determine
(however that's not to say that the problem doesn't originate with
ppp in the kernel). There are a few packet errors (about 1 per 1000).
Netscape continues to function well with Linux kernel 2.2.16 -- but
not with 2.4.0.

People have suggested various things (eg upgrading programs to later
versions). I have tried most of them, without success. Somebody
recommended I turn to the kernel mailing list. If this is not the
right place for my enquiry I apologize (where else?). But if somebody
recognizes these symptoms I would be very grateful for a diagnosis...

Thanks,
Roger Young

Just a data point - Netscape 4.76 is working wonderfully
for me on several 2.4.x systems - well, netscape does die
fairly often with bus errors, but when it's running it runs well -

I can be a little more specific on this point. Netscape with
kernel 2.4.0 _does_ connect/download at a few local (New Zealand)
web sites (maybe 10% of those I've tried). I can't download
from _any_ distant site. It doesn't die, it just doesn't function
properly.


Several people have suggested I remove ECN from the kernel, or
disable it. Well, ECN has never been selected as a config option
in the kernel, so this is not the source of the problem....


Thanks for your suggestion,
Roger Young.

perhaps you have an upstream blocking icmp and having a lower MTU?  Try
setting your MTU down to 576 and see if packets flow.

For me, netscape is netscape.  I.e. gobble memory for a few days until I
decide to restart it.  Netscape rarely dies on me.
