Ssh authentication from .NET webpage to UNIX is not working
My .NET website invokes a perl script to perform GIT operations on Gerrit server running UBuntu. In the perl script I connect using passwordless authentication to Gerrit server as below:
system ( "ssh
gitadmin@gerritserver.com 'cd /xyz && git clone xxx' ");
I verified that ssh authentication is set up correctly between windows client and Unix server. This script works well from windows command prompt but when run from the context of website the page hangs at the ssh command execution.
I have ensured that the user account the website and application pool are running under is the same as the user account ssh authentication is set-up for. Any idea why ssh is unable to authenticate from the website? It looks like the permissions on the ssh process in the context of IIS are not the same as outside it.
As an alternative I have been looking into password-specific authentication using ssh and host-based authentication. Is host-based authentcation possible between windows client and unix server?

sieveshell - remotely manipulate sieve scripts
SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port]
sieveshell --help
DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress.
The following commands are recognized:
list list scripts on server.
put <filename> upload script to server.
get <name> [<filename>] get script. if no filename display to stdout
delete <name> delete script.
activate <name> activate script.
deactivate deactivate all scripts.
OPTIONS
-u user, --user=user
The authorization name to request; by default, derived from the authentication credentials.
-a authname, --authname=authname
The user to use for authentication (defaults to current user).
-r realm, --realm=realm
The realm to attempt authentication in.
-e script, --exec=script
Instead of working interactively, run commands from script, and exit when done.
