Trouble with connect to www.aeroflot.ru

Leonov Aleksey
Hi folks,

I can`t  connect to www.aeroflot.ru from lynx on openbsd 5.4. I can connect from gentoo, windows. Anybody can connect to wwe.aeroflot.ru from openbsd 5.4?

timout. In tcpdump i see sync, but not get ack from aeroflot.ru. From
windows i can get aeroflot.ru.

Ooops on my side. I did not mean to test ftp but just use a different
client (OpenBSD's ftp(1) handles http as well) and forgot the http://:

ftp -o aeroflot.html http://www.aeroflot.ru
Trying 195.8.62.75...
Trying 195.8.62.76...
ftp: connect: connection timed out

There was a thread recently on that problem that I cannot find anymore.
But it boilt down to the user agent your client reports. Try to change
that...

Bye, Marcus

It's not an OpenBSD/Lynx specific problem. I just tried connecting with
SeaMonkey (on /2), and I get a time-out also.

Odd.  Just tried it. Works on Linux, doesn't on OpenBSD.

Not related to user agent; it seems to not respond to SYN.  Perhaps
their running PF and filtering us!

I think this is the case.  I'm behind a transparent http proxy (Squid)
on OpenBSD, and from Windows http://www.aeroflot.ru times out, and
https://www.aeroflot.ru (which bypasses the proxy) works.

Just for the fun of it: it works from FreeBSD 8.x and SunOS 5.10 too,
so maybe it's more like "only OpenBSD can't connect"?

If you read my previous reply, you'll see that /2 is blocked also :)
