RE: Xterm issues

Or, to be slightly more secure:
xhost +hostname_or_ip_of_sun_server  

And if you issue 'xhost', you'll see the list of hosts authorized to connect to your X server.
If you do xhost +, it disables host-based security, any host can connect.
If you do xhost -, it turns on host-based security, only authorized hosts can connect.
'xhost +hostname' authorizes a host
'xhost -hostname' de-authorizes a host. (But I don't think it will kill existing connections.)  

Hope that helps,

Issue 'xhost +' before you ssh to your Sun server.

Hi all,

 

I am having some problems getting the installer to startup on a new
laptop and was hoping I could get some help from the list.

 

I have installed cygwin with the X11 option. If I start cygwin and type
startx I get an X window to open up without any errors.  If I do a
netstat -a at this point I see something listening at port 6000 which is
what I believe I should expect.  

 

TCP    mycomp:6000       mylaptop:0  LISTENING 

 

I login into our Sun box and export DISPLAY=<my laptops IP>:0.0.  I then
kick off xclock for a test.  After executing xclock, the process will
hang for a bit before returning the error message 

 

Error: Can't open display: <my laptops IP>:0.0

 

While the xclock command is hanging, I perform a netstat -a on the sun
box and see the following:

 

<sun server>.54453         <my PC>.6000     0      0 24820      0
SYN_SENT  

 

The sun server is resolving my laptop name incorrectly, but since I am
setting my display to the IP address I am not sure how much that
matters.  

 

On the sun server if I try to telnet to port 6000 I get the same
SYN_SENT message from netstat 

 

<sun server>.54864         <my PC>.6000     0      0 24820      0
SYN_SENT

 

 

Is it possible that I am running into a windows firewall issue on my
laptop?    I don't have permissions to turn off the windows firewall,
but was told by desktop support that he opened port 6000.  I am not sure
if his change worked though

 

Any help would be appreciated

 

Thanks
