Make sure to close your FastX client (on the machine your working on), re-open the FastX application, and try again. When the network (your client IP address) is changed out from underneath your host, the FastX client needs to be restarted.
Verify that you can ssh to the host you’re attempting to FastX to if you can't ssh then FastX will not work. You can also try to use the web FastX version by pointing your browser to http://mtmoran.uwyo.edu. If neither of these work for you, then there's a high probability that the desktop version of FastX will not work.
If you can't even ssh then it could be the destination host doesn't allow ssh from where (the network or IP) your coming from.
This could be for a number of reasons, some listed below.Could be the host you are trying to ssh to requires you to have a UW IP. If that is the case then connect to the UW VPN first then try again.
It could also be that you’re coming from a network or IP that is blocked (temporarily or permanently) from the campus border routers - if you suspect this then you can contact the help desk at 6-HELP or open a Team Dynamix ticket.
Your ssh client could be misconfigured, make sure you have your client configured for ssh v2.
Make sure DNS is working on your host (both forward and reverse lookups), this means you can open up a terminal or command line and type 'nslookup mtmoran.uwyo.edu and have it return an IP list (10.98.192.6 and 10.98.192.5), then type "host 10.98.192.6" or "host 10.98.192.5" which should return a possible hostlist.
If this doesn't work you may have a name service resolution problem on your client. You can fix it or you can just use the IP address instead of the name.
Make sure you have the latest FastX, you may need the new one - to get the new one or compare the one you have with the new one.
To find the version number that your running (go to FastX and click on 'help' > 'about')
To download and install the new client see the instructions above.
You may need to delete the sessions files in your home directory and try again.. (with %hostname% being the one that's having issues) in your home directory, do (by 1st ssh'ing to a host which mounts your home directory such as mtmoran.uwyo.edu.
cd .fastx_server/%hostname%/sessions
rm -rf C-*
OR you can just remove or rename the entire .fastx_server/%hostname%If things are still not working... Does FastX to that server work from a different FastX client (if you have this on another client to test).
If all else fails, please send an email to arcc-infohelp@uwyo.edu or open a Team Dynamix support ticket which includes the version of FastX your using, the operating system your using (linux/osx/windows, etc), if Linux the Linux distribution name and version number, the host IP you are working from (e.g., one way to get this is to visit http://www.whatsmyip.org/ and tell us what "your IP" says. This only works from off campus.), and other error messages and information is helpful including if you've successfully done this before and this is a new problem or if this is your 1st time.
