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,

From: [] On Behalf Of Mike Schmitt Sent: Thursday, September 07, 2006 3:05 PM To: Subject: Xterm issues 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
