Section 3-3: No Connection to Remote Host

[ Previous chapter ][ This chapter ][ Next chapter ]

• Check host specification (name): typographic or spelling error?

• Host and/or network temporarily down: Try to conntact another host. Same problem?

The host and/or network might be misconfigured. Check from another host whether you can reach your own node or the target node (e.g., basel.ch.embnet.org) with the appropriate command:

 

  
 % ping basel.ch.embnet.org
  

  

As mentioned before , the connection of an X process requires that you permit access to your host. A frequent problem on personal computers is the limitation of the X-server programs (refer to the manual to optimise memory or other resources). Either you need to restart the X-server program or you reboot the personal computer.

If a special program fails, try to open a well-known program (such as a clock or terminal window). Some applications require specific performance features of local displays. Postscript viewers and molecular modelling programs are frequently affected if you work in heterogeneous environments.
