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.

Hello all, On Redhat 6.2, the PAM_unix module logs the session opening, but not the session closing. This was logged as of 2.3.0p1. Upgrading to 2.5.1p1 makrs the start of the problem.

I do not often use X11 - but when I do I prefer to enable X11forwarding, and when finished - turn it off. This is preferable, imho, to having "clear" X11 processing when local - and otherwise impossible when working remote. Working with openssh-7.5p2 I cannot figure out what (extra) I need to do with sshd_config to get it working. I know that there is a security-fix starting with

I encounter a strange problem with scp / sftp: I travel quite a bit. Normally I never have had any problems using ssh / scp / sftp to connect from my laptop to my computer at home / in the office. Currently (for the next 6 months, too long to ignore it) I'll stay in a place where scp / sftp seem to fail, while as usual I have no problems to establish an interactive ssh connection to these

Hi guys, I have a server setup with openssh-5.0p1 and use some users as sftp-only chroot accounts. The following configuration yields exactly the result I want: user is chrooted, logs to syslog, all is good. #================================================# Subsystem sftp internal-sftp -f AUTHPRIV -l VERBOSE Match User fredwww ChrootDirectory %h #ForceCommand internal-sftp
