SOT: Nix shell script to test if CF is running on port xxxx
I know I have seen this done somewhere! I want to write a 'Nix shell script to see if a cf server instance is running (accepting requests) an a given port - say 8101 This is for OS X but should work on any 'Nix flavor. Any help would be greatly appreciated TIA Dick [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings] [Donations and Support]

netstat -alpn | grep 8101
then pipe to something like 'awk {print $8}' that will get you the process
name, just grep for whatever your cf server shows up as when you run the
script by hand.

On OS X, if I use the above I get:
Richard:~ richard$ netstat -alpn | grep 8101
netstat: n: unknown or uninstrumented protocol
Richard:~ richard$
So I try
Richard:~ richard$ netstat -alp | grep 8101
netstat: option requires an argument -- p
usage: netstat [-Aan] [-f address_family] [-M core] [-N system]
netstat [-bdghimnrs] [-f address_family] [-M core] [-N system]
netstat [-bdn] [-I interface] [-M core] [-N system] [-w wait]
netstat -m [-M core] [-N system]
Richard:~ richard$
So, I listed the protocols -- & I don't know which one(s) to check for.
What I am trying to do is write a script that automates CF startup, and
sleeps (or loops) until CF is up and the port is accepting http
requests.
I have modified an example I found to do this by invoking a Perl script
that, in turn, interacts with telnet ( apparently shell scripts have
difficulty interacting ).
#!/usr/bin/perl
use Net::Telnet;
$telnet = new Net::Telnet ( Timeout=>30, Port=>8081, Errmode=>'die');
$telnet->open('localhost');
$telnet->waitfor('/220/');
$telnet->print('hello just-testing.org');
($output)=$telnet->waitfor('/250/');
$telnet->print('quit');
I'd rather not use an additional Perl script if possible)
I can brute force a delay using a long sleep, but this is not very
elegent
Maybe the expect command will allow me to script telnet interaction.
If you could point me in the right direction, I will appreciate it.
TIA

Dick,
use the man pages to see the options for netstat...I don't run OSX or
I'd give you the fix.
just type:
man netstat

I run a farm of linux servers and the following worked fine for me on my systems: netstat -alpn | grep (my port here) so your main goal is just to see if the service is running? why not just run the cfstat utility? or are really trying to get the port too? you can also check the jrun.xml file to see what port it is setup to run on here: /opt/coldfusionmx/runtime/servers/default/SERVER-INF/jrun.xml Hope that helps! -Josh > Dick > > Richard:~ richard$ netstat > Active Internet connections > Proto Recv-Q Send-Q Local Address Foreign Address > (state) > tcp4 0 0 10.0.1.2.54157 idisk.mac.com.http > ESTABLISHED > tcp4 0 0 10.0.1.2.54156 adsl-67-124-145-.hp-pd > SYN_SENT > tcp4 0 0 10.0.1.2.53939 mail.mac.com.imap > ESTABLISHED > tcp4 0 0 localhost.ipp localhost.53844 > ESTABLISHED > tcp4 0 0 localhost.53844localhost.ipp > ESTABLISHED > tcp4 0 0 localhost.53843localhost.ipp > CLOSE_WAIT > tcp4 0 0 localhost.53490localhost.51004 > CLOSE_WAIT > tcp4 0 0 localhost.53489localhost.51004 > CLOSE_WAIT > tcp4 0 0 localhost.53353localhost.51004 > CLOSE_WAIT > tcp4 0 0 localhost.53352localhost.51004 > CLOSE_WAIT > tcp4 0 0 10.0.1.2.62793 idisk.mac.com.http > CLOSE_WAIT > tcp4 0 0 10.0.1.2.61312 mail.mac.com.imap > ESTABLISHED > tcp4 0 0 localhost.59549localhost.ipp > CLOSE_WAIT > tcp4 0 0 localhost.59548localhost.ipp > CLOSE_WAIT > tcp4 0 0 10.0.1.2.49357 mail.mac.com.imap > ESTABLISHED > tcp4 0 0 localhost.netinfo-loca localhost.972 > ESTABLISHED > tcp4 0 0 localhost.972 localhost.netinfo-loca > ESTABLISHED > udp4 0 0 localhost.53331localhost.1023 > udp4 0 0 *.50421 *.* > udp4 0 0 *.**.* > udp4 0 0 *.svrloc *.* > udp4 0 0 *.**.* > udp4 0 0 *.**.* > udp4 0 0 localhost.49160localhost.1022 > udp4 0 0 localhost.49159localhost.1022 > udp4 0 0 localhost.1022 *.* > udp4 0 0 localhost.1023 *.* > udp4 0 0 10.0.1.2.ntp *.* > udp4 0 0 localhost.ntp *.* > udp4 0 0 *.ntp *.* > udp4 0 0 *.mdns *.* > udp4 0 0 *.ipp *.* > udp4 0 0 *.bootpc *.* > udp4 0 0 localhost.netinfo-loca *.* > udp4 0 0 *.syslog *.* > udp6 0 0 *.514 *.* > icm6 0 0 *.**.* > icm6 0 0 *.**.* > Active LOCAL (UNIX) domain sockets > Address Type Recv-Q Send-Q Inode Conn Refs Nextref Addr > 2f7fdc8 stream 4781 00000 > 2f7f5b0 stream 0 00000 > 2f7f9d8 stream 0 00 2f7f9a000 > 2f7f9a0 stream 0 00 2f7f9d800 > 2f7fe70 stream 0 00000 > 2f7f620 stream 0 00000 > 2f7fb60 stream 0 00000 > 1d69460 stream 0 00000 > 2f7fd58 stream 0 00000 > 2f7fd20 stream 0 00000 > 2f7f930 stream 0 00000 > 2f7fc78 stream 0 00000 > 2f7ffc0 stream 0 00000 > 1d69150 stream 0 00000 > 2f7fc40 stream 0 00000 > 2f7fa48 stream 0 00 2f7fce800 > 2f7fce8 stream 0 00 2f7fa4800 > 2f7fcb0 stream 0 00000 > 2f7fa10 stream 0 00 2f7fab800 > 2f7fab8 stream 0 00 2f7fa1000 > 2f7ff18 stream 0 00 1d6903800 > 1d69038 stream 0 00 2f7ff1800 > 1d69188 stream 0 0 2b82bf0000 > /tmp/webdavDtD2qQ > 2f7fd90 stream
Re: SOT: Nix shell script to test if CF is running on port xxxx
Josh Thanks for your help Based on what you posted, I did some experimenting and found something that appears to work --the first 2 tests were run after the server (9090 in this case) was started, but had not yet become ready. The 3rd test shows the server is ready. So it, appears that I have something that I can test for in a loop. Is there a "best practices" wway to test for something like this -- say with a sleep for a few seconds, and a max number of iterations so it doesn't loop for ever?
