cygwin sshd will not run under McAfee VirusScan 8.0i
Hi All After upgrading from VirusScan 7.1 to 8.0i I receive the following error every time a connection is established to CYGWIN's SSHD server. The client connection then immediately fails. If VirusScan is disabled everything works fine. The SSHD server also worked fine under VirusScan 7.1. As a workaround, I've hacked the ssh-host-config file to add "-y McShield" to the "cygrunsrv -I" command. However, there's a problem somewhere. Should we: a) treat this as a McAfee bug and just let people search the mailing list archives until McAfee decides to fix it; b) treat it as a McAfee bug and automatically add "-y McShield" in ssh-host-config if that service exists; or c) investigate it as a possibly cygwin sshd bug; ?

killing processes owned by others with kill.exe
Hello, I've noticed that /bin/kill.exe is unable to kill processes that are run as another user (e.g. SYSTEM) (even with -f). Is this intentional? If not, would it be possible for someone to use the attached code to make it possible? It is basically a regular version of "windows" kill, except that it gets "debug privileges" before trying to kill the process - a nice trick left over from the NT 4.0 resource kit days. Currently, I have to distribute my own fkill.exe to all the systems where I need it, but it would be handy if it was part of Cygwin. I know this is a pretty lazy request, but it seems like functionality that many people might use. (It's especially useful for killing broken windows services that run as localsystem, and don't shut down properly). Thanks, Rob. P.S. - I would do this myself, but I don't think I'm qualified to mess with core Cygwin stuff. fkill.c Description: Binary data -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
read-only mounts
Hello, I've searched the mailing list archives, but haven't found anything recent/relevant. Is there any way to create a mount point that is read-only by everyone? The reason I want to do this is because I want users logging in anonymously to my inetd ftpd to be able to access directories not under the ftp user's home directory. The reason why I want to set read-only access at the mount table level (instead of the file level) is because I can't guarantee that various windows operations won't mess up the access bits.
