[pca] Question on setting up local caching proxy for pca

Gurugunti, Mahesh Mahesh.Gurugunti at alliancebernstein.com

I was able to figure out,
 
on the client side my patchurl was pointing to wrong location.
 
Thanks.
 
Mahesh

On the server /pcarepo (patchdir) is owned by "daemon"

drwxrw-r--   2 daemon   daemon     40960 Jul  9 09:23 /pcarepo
bash-3.00# 

 
What I fail to understand is on client side when "pca -d patchnum"  is
initiated , its trying to write into cgi-bin directory, somehow its
thinkng that cgi-bin is the patch download directory.
 
"Connecting to amaeng3.acml.com|10.80.61.32|:80... connected.
HTTP request sent, awaiting response... 500 Can't write to patch
download directory /export/opt/jumpstart/www/cgi-bin/.
09:23:38 ERROR 500: Can't write to patch download directory
/export/opt/jumpstart/www/cgi-bin/.."
 
Does it have anything to do with pca-proxy.cgi script, does it need some
tweeking somewhere?

Mahesh,

  "Can't write to patch download directory" 



		You patch directory should be "owned" by the daemon
which starts the httpd on your PCA Proxy/Cache Server. On my server
webservd is the ID which starts httpd, so I have my /pca/Patches
directory owned by webservd and make sure u have at least 764 as
permission.
		


Let us know how your fare.

	This is odd. Please add debug=1 on the client side too and run
pca -d 119254 and see what error messages you get and where it is
pointing to.

		Mahesh,
		1. Please paste your Server Side /etc/pca.conf
		2. If you have debug=1 in your /etc/pca.conf, then on
the Server (PCA Proxy) side there will be a file
/tmp/pca-proxy-debug.txt If you can paste the relevant text of this
transaction here, it would help to know why it is not communicating.
		
		Usually, when I get that error, it usually means that my
PCA Proxy /etc/pca.conf is not correct.

				Here is how I have mine setup:
				
				Server: /etc/pca.conf
				user=userid
				passwd=password
				patchdir=/pca/Patches/

patchurl=http://pcaproxy.home.com/Patches/pca-proxy.cgi?
	
xrefurl=http://pcaproxy.home.com/Patches/pca-proxy.cgi?
				
				1. Make sure that you DO NOT have any
http_proxy settings on the Client server for ROOT or Other IDs which use
pca.
				
				2. Make sure you have CGI Enabled on the
HTTPD Server. Create test.cgi with the following contents and make sure
it is executable. This will be a good test if your HTTPD support cgi
execution
				#!/bin/sh
				
				# disable filename globbing
				set -f
				
				echo Content-type: text/plain
				echo
				
				echo CGI/1.0 test script report:
				echo
				
				echo argc is $#. argv is "$*".

				Can amaeng3.acml.com talk to the net?
In essence amaeng3 is acting as a proxy... 

				 

				Can you run just pca on amaeng3 and have
it go to sunsolve?

				 

				On amaeng3 make sure your /etc/pca.conf
is setup as normal.

				I have setup a server that contacts sun

fine.

				 

				I am in the process of setting up local
PCA server , I followed all the instruction on this page

				of copying pca as pca-proxy.cgi

				settting /etc/pca-proxy.conf

				restarted httpd (amaeng3 is the planned

				Any ideas? Also, I need to know if there
