Bug 197182 – net-misc/openssh-4.7 gives tons of "rcvd too much data X win Y" errors with USE=hpn

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Jeff Mitchell 2007-10-26 22:36:29 UTC]

I often use SSH to connect to a system for which I have "DynamicForward 1080" configured, and then use this as a dynamic SOCKS proxy when web browsing among other things.

Since upgrading to 4.7p1, I get tons and tons of "rcvd too much data X win Y" messages in the console that I have SSHed from as I browse around the Internet, and web pages randomly stop loading, sometimes immediately, sometimes after part of it has been loaded.  X is some number that is not always the same, same for Y.

Sometimes I get a few of these messages on one page.  Sometimes the ssh
window just scrolls and scrolls with them.

Reverting to 4.6p1 fixed this issue.

Reproducible: Always

Steps to Reproduce:
1. Use OpenSSH 4.7.
2. Open a SSH connection to a client with DynamicForward enabled to have it act as a SOCKS5 proxy.
3. Use the proxy, i.e. for browsing web pages.

Actual Results:  
The SSH console gets those error messages, and connections through the proxy are randomly cut off.

Expected Results:  
It should have kept connections alive through the proxy, like version 4.6 does.

I think this whould be an upstream Issue and is not directly gentoo-related...

[Comment 3 Dmitry Karasik 2008-06-03 19:31:39 UTC]

I was getting this problem too, with openssh-5.0p1. Removing the hpn use flag solves the problem.

[Comment 4 Jeff Mitchell 2008-06-03 19:44:39 UTC]

I could have sworn I closed this. Issue with the HPN patch since 4.7 or so, so it's upstream.

[Comment 5 SpanKY 2008-06-03 20:00:16 UTC]

if you havent e-mailed the hpn guys, please do so now ...

[Comment 6 Jeff Mitchell 2008-06-04 04:33:50 UTC]

FYI, there is a bug for this on the mindrot bugzilla, which is probably a better place to continue this (to keep vapier's mailbox cleaner  :-) )
