squid and dansguardian - problems!

[dazaau]

Hi,
I am new to linux and quite honestly don't know what I am doing half the time. I have a server running nicely though on the network using samba with no worries. I am now trying to get a web filter running and have followed the directions at http://www.linux.com/article.pl?sid=04/07/01/1833212 and i can't get squid to start or dansguardian. Squid fails and in the squid log file it says something about setting the 'visible_hostname'

I cant figure it out, can't find anything on line either. please let me know if you know what is wrong or if you know of a setup guide that works. It is really frustrating not understanding what you are doing of course now because of the Iptables rules I can't use the internet on the server anymore, need help!

Thanks
Daniel

Hi,
please put the correct error message !
Is it this one :

FATAL: Could not determine fully qualified hostname. Please set
'visible_hostname'

?
This setting allows you to present a usuable hostname in error-messages.
visible_hostname proxy.yourhost.com

[dazaau]

yep that is it :-) Any ideas on how to make it work. I would really like to get it running as we really should have it up and running for all the users here.
Thanks
Daniel

what host am I supposed to put in there? my ISP? My web domain? Thanks for your help! Sorry I don't quite understand, I am quite new to servers and Linux!

First, try to put your hostnaem like it is in /etc/hosts file :

[root@squid ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
10.1.11.156 squid squid.mydomain.com

Second, try to comment the visible_hostname option...

[dazaau]

thanks! looked in my hosts file and it just says
order hosts,bind?

[dazaau]

OK I ran it in terminal and just got 127.0.0.1 server localhost.localdomain localhost

is that what I put in?

127.0.0.1 server localhost.localdomain

[dazaau]

didn't like any of those. how do I het to be root@squid. I am in root@server?
Thanks!

Cause your box is named "server" ...
It looks like :
user @ machine
What is your ip ?
what is your /etc/hosts file ?
not /etc/host.conf...
after 127.0.0.1 line add your network ip and put a name :
assume your ip is 192.168.1.100 for your squid server and is named "server" and your domain is "mydomain.com"
here is your /etc/hosts file :

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.100 server server.mydomain.com

after, put server.mydomain.com in the visible_hostname option...

Did you try to comment this one ?

[dazaau]

ahh, I think I begin to see the light, yeah It is #none by default but still doesn't work.
Really weird I just logged out of root and back in and now it seems all the gnome files are corrupt and the interface isn't working and I get greeted with 10 error messages when I log in? Anyway I have moved to xfce and it is working OK.

[dazaau]

I set it up for my NIC's network address and then wrote server server.mydomain.com and then entered

server.mydomain.com into the squid.conf and it still doesn't like it.

[foobar47]

Strange !
What is your squid.conf file ?

you should have something like that :

# TAG: visible_hostname
# If you want to present a special hostname in error messages, etc,
# then define this. Otherwise, the return value of gethostname()
# will be used. If you have multiple caches in a cluster and
# get errors about IP-forwarding you must set them to have individual
# names with this setting.
#
#Default:
# none
visible_hostname server

try to only put 'server' without domain name.

What is the result of hostname and hostname --fqdn command ?

Restart your network service too...

[dazaau]

the result is server.

One quick question: if you were to set all the permissions of the files on the HDD to 777 and then back to 755, Would that cause a problem? My PC is having a lot of problems now. I might have to reinstall linux. probably shouldn't have done that!

[foobar47]

Why did you apply chmod 777 to all files ?
Try to disable SELinux...

Did you put this one :
visible_hostname server

[dazaau]

yeah I know, dumb, dumb I shouldn't have done it. SElinux was ulready turned off. Although it my be have come back on when I rebooted? Thanks so much for all the info you have given me. I think I am getting somewhere. on the chmod 777 thing. gnome won't work. KDE is half working with programs like text editor not working properly. Firefox won't work either. do you think it was my little chmod 777 chmod 755 trick? It was fine untill hours after when I logged out and logged in again. I am a little worried if it is not that and it is the HDD or something becuase it is a file server And I wouldn't like to explain that! I think at 12:30am I better be off to bed.

Thanks ever so much, I am sure that what you have explained will get me closer to getting this going! I feel so lost when it comes to linux and finding answers on the net. So much linux-language that a windows boy like me doesn't understand! But I am learning! I'll look at this problem again tomorrow
Thanks again
Good night
Daniel
