I noticed a worrying thing! Yesterday I installed squid on my machine
at home Centos 5.4.
By default, I was installed squid 2.6 from the Centos repository squid
2.6.
1) I did uninstall "yum remove squid" .
2) I have downloaded from http://people.redhat.com/~jskala/squid/ squid
2.7 Stable-1.el5
3) remove /etc/squid/ , /var/log/squid , /var/spool/squid
4) yum localinstall --nogpgcheck squid-2.7.STABLE7-1.el5
5) I had to create /var/log/squid/run directory manually for squid .pid
file
permissions 776 owner and group squid

[root@proliant squid]# ls -al
drwxr-x--- 3 squid squid 4096 mar 15 12:55 .
drwxr-xr-x 19 root root 4096 mar 16 04:05 ..
-rw-r----- 1 squid squid 340215 mar 15 20:20 access.log
-rw-r----- 1 squid squid 153839 mar 14 04:02 access.log.1.gz
-rw-r----- 1 squid squid 761563 mar 15 23:07 cache.log
drwxrwxrw- 2 squid squid 4096 mar 15 23:07 run

6) squid -z
7) iptabpes -A INPUT -p tcp --dport 8080 -j ACCEPT (and another rule for
port 80)
8) service squid start show [FAILED]

AND I RECEIVE ERROR !! THE SAME LIKE IN MY PRODUCTION SERVER !!!!

service squid status show running !! But

service squid restart:

Zatrzymywanie squid: [ OK ]
Uruchamianie squid: [NIEUDANE]
[root@proliant /]#

NIEUDANE = FAILED

All of above things are made from root account.

In cache.log there is no warnings or errors ! What's going on ? How can
I track error ?
How can I find an error or the cause of the error?? squid -X show
nothing wrong.
What am I doing wrong?

iptables -t nat -A POSTROUTING -o eth0 -s 192.168.0.0/24 -j SNAT
--to-source 192.168.1.2

I noticed that when I type :
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT
--to-port 8080
clients from WAN (internet side) can't connect to my site on apache (all
traffic 80 is redirected to squid but I need httpd to work on 80 on
eth0, squid works on eth1)

I add -s 192.168.0.0./24
iptables -A PREROUTING -t nat -i eth0 -s 192.168.0.0/24 -p tcp --dport
80 -j REDIRECT --to-port 8080
now clients connect to my site but connection to internet from LAN to
WAN is very slow. I think it was creating a strange loop ??

PLEASE HELP!!
