...uous long" (or so). I think this is a bug in the - commercial and expensive - compiler. I didn't try gcc on that platform, yet. No, I didn't try 0.9.6, yet. 2. scp will hang after the file transfer(s) The "fix" is to change the line 495 in serverloop.c from shutdown(fdin, SHUT_WR); to shutdown(fdin, SHUT_RDWR); The same which I did in 2.1.1. 3. X11 forwarding does just work for standard X clients - if you configure it with --with-ipaddr-display - but not for all X applications. The reason is that Siemens is using a named pipe in /tmp/.X11-unix for X co...

On a non-trusted system with HP AnsiC it seems to work if changing shutdown(fdin, SHUT_WR) to shutdown(fdin, SHUT_RDWR) in serverloop.c (lines 320 & 464) On a trusted system with gcc however this does not seem to have any effect. Here I use #define USE_PIPES 1 in includes.h as workaround I think I will have to do some more checks with compilers/(non-)trusted systems......

...ompletely. That is we seem to be unable to rename a file that has an open file handle (either owned by the same process doing the rename or a different process), this is not a problem on a local NT drive or on an NFS mounted drive.

Hi! I am resending the following message about problems with utmp handling. * In the meantime I had some request in private mail from people asking whether I have new information. * The problem is still persistant in 2.9p2. * My own new investigations show, that the problem only appears with protocol 2, not with protocol 1, I therefore only started to note it when protocol 2 became the

This patch is against Cray patch against openssh-SNAP-20010710. Here a few notes about them: 1) rijndael does not work on cray due to the fact it is rooted in 32 bits. I looking for a fix, it may come form Wendy Palam. For now the cray default to the following cihpers for ssh version 2 ssh are: 3des-cbc,blowfish-cbc,cast128-cbc,arcfour 2) Crays don't have setitimer so I

Hello, ? I need to make many (>50) ssh connections from linux to cygwin at the same time. Using Windows 2000 Server (OpenSSH_4.3p2, OpenSSL 0.9.8b and updated cygwin) and Linux RHEL4 (OpenSSH_3.9p1, OpenSSL 0.9.7a). ? It's been difficult to optimize many simultaneous connections. Here were some issues: 1.?????? On Windows XP/Professional, Microsoft intentionally cripples the TCP/IP stack.
