Figure 31 Flowchart 4 – X.25 Configuration check
Flowchart 5 – Procedures and notes
Use these procedures to verify your IP addressing and remote host connection.
Note 5-1 – Ping
Use ping on your own IP over X.25 address, for example:
ping 195.25.0.13
Do not use aliases (for example, as defined in/etc/hosts), since this may introduce other errors.
Use the Break key or Ctrl-C to terminate ping if you have not set the number of packets with the
-n option.
Note 5-2 – Checking your IP over X.25 configuration
If ping returns errors such as “100% packet loss,” or “Network Unreachable,” use
x25stat -a to check your address configuration. The most likely causes of problems are:
• No IP address was specified when X.25 was initialized (either in the X.25 configuration file
or as a command line option to the x25init command).
• IP to X.121 address mapping has not been initialized (using the -a option with the x25init
command).
• The IP address is incorrect.
• The mapping of your IP address to your X.121 address is incorrect. Check the IP to X.121
map table file (the default file is /etc/x25/ip_to_x121_map).
