...ny help would be very appreciated, Ive traced it down this far and could use some further pointers if possible. Seems an obscure problem at this stage.

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.

After upgrading a Linux system from OpenSSH 6.7 to 6.9, Cisco switches/routers can no longer scp config files to/from the system. The last debug entry before the Cisco device closes the connection is "debug1: server_input_channel_open: confirm session". The next line is "Connection closed by x.x.x.x". Anyone else seen this or know of a fix? The Cisco device gives "Undefined error" when scp'ing a config file from the server, and "Permission denied" (probably not the correct error message)...

I think I've found two minor memory management issues (neither exploitable in any way) in OpenSSH 3.7.1p2 that should probably be addressed. In serverloop.c, function server_input_channel_open(), the ctype variable is a char *, dynamically allocated in packet_get_string. It's xfree'd at the end of the function. However, before that, it's passed to server_request_session/server_request_direct_tcpip, which call either channel_new or channel_connect_to, passing in ctype....
