Problems with DansGuardian


I have a problem with DansGuardian,

Reading in a blog here:
https://www.linuxquestions.org/quest...ardian-261197/

The same problem has the user: win32sux, a few years ago, but the answer to that does not appear.

Synopsis: I have a linux box with squid+dansguardian, configured as transparent proxy on port 80, but certain websites loads very slow with NO IMAGES (ex: www.facebook, www.yahoo.com, www.dell.com) , in the post I linked before is exactly my problem, but the answer never appear.

Please if someone knows how to contact with WIN32SUX or have the solution I apreciate so much.

jrober2p@hotmail.com or in this pages. (user: jrobe2p)


Many thanks.

One use has replied to win32sux, with some solutions like making changes to file /etc/dansguardian/pics and then reloading dans or with dansguardian -r or dansguardian -q.
Have you tried that.

Many thanks for your response,

After a few days of sleepless,
investigating about this, tracing the possible reason for this behavior I discover that the problem is not the squid, dansguardian, snort ... the <<mod edit: profanity cleanup>> problem are the rules in the firewall. I'm looking for an update for our firewall-rules.

For test and solution this problem meanwhile I found an update for my firewall-rules I did this:

<enter as root>

1st. disable firewall service:
# service firewall stop

2nd. I made a script file with basic rules: ALL PERMITTED.

#vi proxgate.sh <enter>

type this:
---------------------------------------------------------------------
#
# Creando la configuracion para NAT: proxy/router/gateway
#

# Step 1, Activar el reenvío de paquetes:
# echo 1 > /proc/sys/net/ipv4/ip_forward

# Step 2, Limpiaremos las reglas del iptables:
iptables -X
iptables --flush
iptables --table nat --flush

# Step 3, Activaremos el NAT con enmacaramiento en las reglas del iptables:
# eth0 - interface publica (internet)
# eth1 - interface interna (red privada-mired-)
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth1 -j ACCEPT

#
# Fin Configuracion
#

---------------------------------------------------------

save file and then run it:
# sh proxgate.sh
and now you have a transparent proxy gateway (with your legs open to the world jajajajaja, but functional)

3er. You must look for an update for your firewall rules.

Many thanks for your help, you give me so much ideas for discover the solution.
