Linux 2.2 (and probably others) have a deficient mmap which has caused a number of problems (e.g. bug #285). A workaround is in development, but it would be helpful to have a configure test to detect the bad mmaps(). Any takers? -d

I just upgraded to OpenSSH3.2.3p1 as it seemed that UsePrivilegeSeparation yes might help with my problem (connections forwarded are owned by root instead of the user I logged in as on the server), but instead, sshd barfs on receiving a connection. Without UsePrivilegeSeparation the server works fine. # strace -o /tmp/sshd.str sshd -d debug1: sshd version OpenSSH_3.2.3p1 debug1: private host

Hullo All I hjave a problem with SaMBa 2.2.1a with HP/UX 11.00. It seems to work fine, but after a couple hours users received a message in Windows (all 95) like that ... "There were no servers to log you into", or something like that (Win95 Brazilian Portuguese). It seems like it can't find the domain master server... Below is my smb.conf... Some help is greatly apreciated...

I added ZSTD support to OpenSSH roughly over a year and I've been playing with it ever since. The nice part is that ZSTD achieves reasonable compression (like zlib) but consumes little CPU so it is unlikely that compression becomes the bottle neck of a transfer. The compression overhead (CPU) is negligible even when uncompressed data is tunneled over the SSH connection (SOCKS proxy, port

I hacked zstd support into OpenSSH a while ago and just started to clean it up in the recent days. The cleanup includes configuration support among other things that I did not have. During testing I noticed the following differences compared to zlib: - highly interactive shell output (as in refreshed at a _very_ high rate) may result in higher bandwidth compared to zlib. Since zstd is quicker

http://bugzilla.mindrot.org/show_bug.cgi?id=205 ------- Additional Comments From mouring at eviladmin.org 2002-04-07 10:28 ------- Created an attachment (id=64) This patch (does not include configure.ac patch) should allow non-mmap platforms to compile, but will not allow them to use privsep period. One has to do more R&D to figure out where to disable compression on sshd since

I've had a consistent problem with Samba from 2.2.1 onwards, maybe even before then, I'm not sure when it started. Anyway, Samba will randomly stop responding to any requests, although it usually occurs after transfering large amounts of data (1 GB+). To get around the problem, I've been restarting samba every night, but we still have the problem occasionally. smbclient shows:
