Cygwin ssh (and basically all terminals except the Windows console) use

Hmm .. this is where it gets even more interesting. If I run:
$ ssh [EMAIL PROTECTED] date
Wed Jun 21 18:02:13 GMTDT 2006
.. then I get a result. But other commands don't, e.g.
$ ssh [EMAIL PROTECTED] cat /etc/hosts
$ ssh [EMAIL PROTECTED] ls
What does 'ssh [EMAIL PROTECTED] cygcheck ls' say?
On Windows 2003, SYSTEM does not have the appropriate privileges to
switch
user contexts, so ssh-host-config needs to create an account that does.
Read <http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-switch> for
details.
Before running ssh-host-config I did:
- Right click My Computer, Properties > Advanced > Environment Variables
- Under System Variables, click New, add CYGWIN as the variable name,
add ntsec as the variable value
- Under System Variables, scroll down to Path, click Edit, add
;c:\cygwin\bin to the end of the string already in the field
Then opened Cygwin on the desktop, ran ssh-host-config and entered:
"Privilege Separation?" Yes
"Create local user SSHd?" Yes
"Install SSHd as a service?" Yes
"CYGWIN = " enter ntsec
Should I have done anything different there on W2003 ?
Depends on what you need. If you need to get output from non-Cygwin
executables, then you'll need to re-install the service with "nontsec"
instead. But this is notably less secure. There should be no need to
do this if you're simply dealing with Cygwin utilities though.
