Re: setgid: Invalid argument

I have cygwin and openssh working, but I am still not connecting
vnc through the ssh tunnel.
For you take note of step 5, 6,and 7.
These steps have taken lots of time to put together.
Hope it may help you.
If you find anything new or need answers, let me know.
Try uninstalling your cygwin, install fresh, and try my steps.
You can also study and try the following the page below.

Tightvnc and openssh

Windows 2000/xp setup
Steps:

1. Router setup and use virtual server, or port forwarding
    forward the computer ip of the server to port 5901 and 5801

2. Install Tightvnc-server
    execute vncserver on windows computer.
    right click on V icon in right of taskbar
    select properties
    select ports in display or port numbers to use
    use ports 5901 and 5801 from step 1
    Enter Password for client to login with
    right click the vncserver icon and select advance.
    Check the loop back enabled box.
   You now have a Tightvnc Server.

3. Install Tightvnc-viewer on the other computer (Client)
    Execute vncviewer in a konsole or find it in a menu.
    enter router wanip with :x which is the xdisplay number
    Example: 65.34.2.212:1
    To find your wanip logon to www.whatismyip.com
    For local use, use the server computer ip.
    To find your ip, In konsole type ifconfig
    In windows ipconfig or winipcfg
    Example: 192.144.3.133:1
    Enter password from step 2
   You should be doing remote control of the server.

Linux Suse setup
Steps:

1. Install Tightvnc-viewer for linux

2. Execute vncviewer in konsole

3. type in the windows server ip with the :1
    type in the password.
    or for internet logon, use the router wanip with :1
    Test it by taking control of the windows box.

4. Install Tightvnc-server for linux
    Execute "vncpasswd" and set a new password for clients
    Execute "vncserver :1"
    The :1 is for xdisplay 1
    You now have a vnc server in windows and linux
    Execute "vncserver -kill :1" to remove the server

5. If you want a secure shell, install openssh in linux.
    I use suse linux.
    In suse goto yast2, system, runlevel editor, runlevel properties.
    Make sure sshd is running.
    For windows find and install cygwin and openoffice for windows.
    They are free programs for windows.
    If you use a router you must forward the server's ip to port 22.
    ssh uses port 22.
    After installing cygwin make group and password according to the
    documentation to be able to login with ssh.

    With nt, 2000,and xp you will need to execute these as is.
    Example 3-5. Setting up the groups file for local accounts
    $ mkdir /etc
    $ mkgroup -l > /etc/group

    Example 3-6. Setting up the passwd file for local accounts
    $ mkdir /etc
    $ mkpasswd -l > /etc/passwd
    These commands will take windows user information and store them in
    a group and passwd file in the c:/cygwin/etc folder.
    Do not change the word /etc/group and /etc/passwd.

6. Now it is time to give it a try. In a terminal window on my own desktop,
    I entered vncviewer -via xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx:1
    where the xxx's represent server IP address in both instances.
    The -via option directs tightVNC to use ssh for a secure tunnel
    through which to operate.
    See man page for -via switch. Type in konsole "man vncviewer"
    Now you can vnc through an ssh tunnel
    which gives you some security.

7. If you change or add any useraccounts or a computer ip in windows,
    you must execute the mkgroup and mkpasswd again to update the files
    located in c:\cgwin\etc\group and c:\cygwin\etc\group
    Also in my suse linux when i had executed ssh I got a warning
    of intrusion.
    I had to delete /home/myuseraccount/.ssh/known_hosts file
    This is the file that has the key for security. If anything
    in the host system changes this key will alert me.
    Just delete it if you know that you are aware of changes to
    your system. Remember that .ssh is a hidden folder.
    In konqueror click on view and show hidden files.

help:
if ssh or vnc login fails look at server ip... use ipconf ifconf winipcf
If you get a localloop back disabled, in windows right click the
vncserver icon and select advance. Check the loop back enabled box.
