[Server-devel] Squid fixed

[Tony Pearson]

Adrian, Sulochan,
Thanks for the guidance. 

==>First, it looks like I have multiple "sysconfdir" directories when I do 
squid -v I see both /etc and /etc/squid:

[root at schoolserver squid]# squid -v

===>Here's the first part of /etc/init.d/squid : 

#!/bin/bash
# squid         This shell script takes care of starting and stopping
#               Squid Internet Object Cache
#
# chkconfig: - 90 25
# description: Squid - Internet Object Cache. Internet object caching is \
#       a way to store requested Internet objects (i.e., data available \
#       via the HTTP, FTP, and gopher protocols) on a system closer to the 
\
#       requesting site than to the source. Web browsers can then use the 
\
#       local Squid cache as a proxy HTTP server, reducing access time as 
\
#       well as bandwidth consumption.
# pidfile: /var/run/squid.pid
# config: /etc/squid/squid.conf
#set -x

PATH=/usr/bin:/sbin:/bin:/usr/sbin
export PATH

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0

# check if the squid conf file is present
[ -f /etc/squid/squid.conf ] || exit 0

if [ -f /etc/sysconfig/squid ]; then
  . /etc/sysconfig/squid
fi

==> Here is my /etc/services with 3128 defined to be for squid

[root at schoolserver etc]# grep -B4 -A4 "3128" /etc/services
ninstall        2150/tcp                        # ninstall service
ninstall        2150/udp                        # ninstall service
afbackup        2988/tcp                        # Afbackup system
afbackup        2988/udp                        # Afbackup system
squid           3128/tcp                        # squid web proxy
prsvp           3455/tcp                        # RSVP Port
prsvp           3455/udp                        # RSVP Port
distcc          3632/tcp                        # distcc
svn             3690/tcp                        # Subversion

==> When I look for 3128 in HTTPD land, I get this:

[root at schoolserver etc]# cd httpd
[root at schoolserver httpd]# grep -R "3128" /etc/httpd
grep: /etc/httpd/run/dbus/system_bus_socket: No such device or address
grep: /etc/httpd/run/avahi-daemon/socket: No such device or address
/etc/httpd/conf/httpd.conf:Listen 3128

==> Here are the relevant lines of the HTTPD configuration:

[root at schoolserver conf]# grep -B11 "3128" /etc/httpd/conf/httpd.conf

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, in addition to the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 80
Listen 3128

==> I added a "#" to comment out the Listen 3128 and that seems to fix the 
problem.  I got
"[OK]" on manually restarting Apache and squid, and it also starts on boot 
now.

[root at schoolserver conf]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd:                                            [  OK  ]
[root at schoolserver conf]# service squid start
Starting squid: .                                          [  OK  ]
[root at schoolserver conf]#

Perhaps Wad should make these changes part of the next XS LiveCD build?
