Sofar, so good. Today, after an initial trial use, I started getting "could notallocate pty" errors, that can be explained by the huge amount ofssh.exe and scp.exe processes left running on the server – they don'ttake up CPU but they do take up RAM (about 2/3MB each). What can bethe problem? Restarting the service does no good – basically theprocesses aren't killed when the user logs off. This can, forseeablycause problems. The user running the service is the one created byssh-server-config. sshd_config : # $OpenBSD: sshd_config,v 1.74 2006/07/19 13:07:10 dtucker Exp $# This is the sshd server system-wide configuration file.
