Top Forums Shell Programming and Scripting FNG Question: Test if remote server has booted Post 302343390 by avronius on Wednesday 12th of August 2009 10:09:38 AM

Word of warning...

Your server may respond to a ping request during the fsck - the network interface is initialized before advancing to the multi-user run level. You may find that the network interface may respond to ICMP echo requests, yet still be in single-user mode. (Your mileage may vary)

One way to test if multi-user services are up, is to attempt to telnet to port 22 (the ssh port). If the service is up, you should see something like:

Code:
root(me)@myhost2# telnet myhost1 22
Trying 192.168.1.101...
Connected to myhost1.
Escape character is '^]'.
SSH-2.0-Sun_SSH_1.1

If the service is not yet up, you should see something like:
Code:
root(me)@myhost2# telnet myhost1 22
Trying 192.168.1.101...
telnet: Unable to connect to remote host: Connection refused
