Re: [ferret_users] Open ferret via remote server

[antonio avio <antonioavio@xxxxxxxxxxxxxx>]

Hi Martin, David, Russ and Ferreters,

Thanks for all your kind responses or suggestions.

I'm working in Linux system.

I start to log in remotely using SSH command as:

ssh -X -p12345 antonio@100.10.0.000     (for instance).

I could show either 'xclock' or 'xterm',

I tried again to run Ferret to make a simple plot. Now the error reduce, but

 still get this error:

PPL+ error: Unable to read "default.spk" to set shade and fill colors.

connect : Connection refused

connect : Connection refused

 PPL+ error: Unable to read "default.spk" to set shade and fill colors.

At line 169 of file symbel.f (unit = 10, file = '')

Fortran runtime error: File ' /fondat.dat' does not exist

type the echo $DISPLAY i got this result:

localhost:10.0

Thanks for any helps.

Regards,

Antonio

Hi Ferreters,

Anybody know how could I open the ferret if I simply access it remotely from another place.
For instance, I installed the Ferret in the main computer of my office and I need to remotely access it from another place.
When, i tried to make a plot: i got this error:

/*No protocol specified*/
/*

/*Can't connect to X Server :0*/
/*Your DISPLAY environment variable must be set to*/
/*point to a working X server.*/

log to the remote server using

ssh -X your_login@server

Check your DISPLAY variable issue "echo $DISPLAY"

After login just try "xterm". If this works X11- forwarding works. Now you can start ferret.

Alternativly you may use the -Y flag. If this does not work, some configuration of the ssh for X11 forwarding may be needed.
Please ask your system wizzard in this case.

/*gsetlinerep()    7 GKS not in proper state: GKS shall be in one of the states WSOP, WSAC or SGOP*/
/*ginqmaxwssttables()   22 Specified workstation type is invalid*/

This may be a result from the missing X11- forwarding.

Seems your ferret environment is not configured well. Please check the installation at the remote machine and
compare with the installing hints at the ferret web pages.

What exactly the command that i have to call before starting to use it.
Thanks

Antonio

Hope this helps,
