is there a way to force wget to use a specific squid proxy when making connections ? - I use a squid proxy normally, but I need this specific request to go via a different one. I dont have to use wget, I just need a way to test squid's blocking rules by requesting various pages through it, this proxy is not my normally proxy on the network and so I cant rely on wget taking the environment variable.
Also, this is as part of a script, so anything that avoids editing wget config files would be best. - Perhaps curl can do this ? - currently im using the exit code of wget to determine if the connection was made.
How can i redirect data received on a port to another port located in a different machine? Can i do this using IPTABLES ?

I have installed squid as my proxy server in ubuntu 10.04 standalone system..Why i have installed squid in standalone sytem is, my friends used to access my system to browse sites and download files..So i have installed squid to block porn sites and downloads..But they simply bypass the proxy by disabling it..I know there is some way to force all browsers to go through proxy using iptables..But how to acheive it..? Is the below command suits my need..?If not what modification should i do..?

sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-port 3128
I am trying to generate a UDP syslog packet from my C application. But I am facing a problem with a Cisco Router ACE that does not like the Source Port being '0' and thus drops the packet.How can I specify the Source Port in the UDP header to '514' as stated in RFC3164 (Section 2: Transport Layer Protocol)? "It is RECOMMENDED that the source port also be 514 to indicate that the message is from the syslog process of the sender"
View 1 Replies View RelatedI'm using a local proxy server VPN'd to another network.
How do I setup either Firestarter or Gufw/ufw to ONLY allow in/out from ONE port? (The one port the proxy uses)
Ex: Firefox is proxied to 127.0.0.1, all ports, and then the proxy picks it up, and sends out on port xxxx, and recieves on port xxxx, then sends back thru 127.0.0.1, back to Firefox.
Any setting/rules I've treid on either Firestarter or Gufw kills the proxy>VPN (Proxy won't connect to remote network)
Addendum: If I start the proxy FIRST, then the firewall, all is good. I'm thinking the proxy uses a port to connect with remote network first, then switches to my configured xxxx port...hmmm
I want to run a proxy server on port 1080, so I typed
Code:
ssh localhost -D 1080

What can I do so that other clients can connect to port 1080 on my server?

It worked on both Mint 5.0 and backtrack 4.0.so I untar the file. cd to the dir and type make then make install and reboot. like I have always done.
I was having to fight with wpa_gui and finally got it working but then it would go in and out on the connect and disconnect feature. so I tried using iwconfig. did not get muc luck with that either so i installed wicd and finally got a ip address after fighting with it would give me in a ping like 75% packet loss. so I read a lot of post and try to find stuff before I post. and while reading I learned that you guys normally ask for info on the hardware and software so here you go. but I will say first that I read about adjusting the mtu to fix packet loss, I showed some of the changes I made in it around the pings I know it is a mess I am sorry I tried to make it readable. if you need more information let me know. I cant get online using a web browser or if I can only for one or two pages. any help would be great. thank you.

View 1 Replies View RelatedI have got a reverse proxy that is working just fine, it accepts requests on port 443 and port 80 and ONLY sends traffic upstream to port 80 to the apache server listening on localhost. I use the following config:
https_port 10.14.1.72:443 cert=/etc/squid/self_certs/site.crt key=/etc/squid/self_certs/site.key defaultsite=site vhost
cache_peer 127.0.0.1 parent 443 80 no-query originserver login=PASS
http_port 10.14.1.72:80 vhost
My problem is the following : The site should act differently in some occasions based on whether http or https was requested. So my idea is to setup second http vhost on apache listening to port 8080 and on that vhost I would server the https code. So is it possible to use SQUID to :
Send traffic destined for port 443 to localhost:8080
and
Send traffic destined for port 80 to localhost:80 ?
I am the new user to ns-2. I would like to know is it possible to send the keys or some value as the packet data (content of the packet) in ns-2 (for wireless environment).

View 2 Replies View RelatedI'm new to linux, but enjoy using it very much, especially without a GUI, console is fun! I need to set up port forwarding. We have 3 servers, 1x running Ubuntu server 8.04 (used as transparent proxy), 1x server 2003, 1x windows xp.
The linux box has the following ips:
eth0 (internal) 192.168.1.5
eth1 (external) 192.168.0.7
Windows server 2003:
192.168.1.6
Windows XP:
192.168.1.9
Router:
192.168.0.1
The router automatically forwards specific ports to 196.168.0.7 (Linux eth0). From there I want to forward port 8585 to 192.168.1.6 and 3000 to 192.168.1.9. Is there a way that I can do this using iptables?
The commands that I think I'm gonna use look like this:
iptables -A FORWARD -s 192.168.0.0/24 -p tcp --dport 8585 -d 192.168.1.6 -j ACCEPT
iptables -A FORWARD -s 192.168.0.0/24 -p tcp --dport 3000 -d 192.168.1.9 -j ACCEPT
Would this be a correct way of doing it? My biggest problem is that I can't test it without going live, and if I go live and something doesn't work, the entire building will be left without internet, people will hate me. Also, The proxy captures all data on port 80 and forwards it to 3128 so that the proxy can monitor the usage, and a few systems runs fine with it, others however can ping websites, and internet explorer says "website found, waiting for reply" but the webpages cannot be displayed.
I have just installed Squid proxy. i also use WPAD to deploy policies for all client. Both works well together. Now i want to configure firewall Juniper SSG140 will be deny all request from client to access internet and redirect to Squid. I mean deny HTTP & HTTPS except Squid (port 3128), even i want to all access to internet have to through Squid proxy. I don't expert about the firewall Juniper. May i know step by step configure it.

My college providers shifted to a different setting.. I'm not sure what needs to be done. On windows, under the connections tab you need to change the proxy settings and put in the IP address and enter the port to 3000. Questions:
1. where lies the linux (ubuntu 10.04) variant to execute the operation.
2. What can be the major obligations of such a change?

View 4 Replies View RelatedWe currently have a SUSE Apache2 reverse proxy server setup to reverse proxy (proxy_mod) our GroupWise Web Access server. Our SUSE box is located at www.domain.com. Our GroupWise Web Access server is located internally and is called GWMail. We are in the process of migrating from Novell to Windows, so we will have an exchange server with OWA access running on a Windows Server 2008 IIS7 box. That one will be called EXMail internally. Right now when someone goes to www.domain.com/gw/webacc it goes to the GWMail internal server from the outside world. This was all set up by previous techs who used Linux more.
We would like to set up reverse proxy to be able to reverse proxy to the Exchange Server from the outside world. Unfortunately the snag we are running into is that Exchange needs to run on port 443, and forwarding to port 443 has been a little tricky. I've read elsewhere we need to implement a generic TCP proxy, such as IPtables. what we need to do to get our SUSU Apache2 server to be able to reverse proxy to our Exchange server on port 443. For the save of argument lets call our SUSE server ExtranetServer. Below is our default-configuration.conf file's configuration:

I want to set the HTTP_PROXY and HTTPS_PROXY and http_proxy and FTP_PROXY environment variables "somewhere", so all programs that recognise these can find them. I need root to find them for slackpkg and sbopkg, I need users to find them for Dropbox, I need them for cronjobs and scripts and wget.So I want to set these environment variables up somewhere, preferably something in /etc and have them set and accessible for everyone and everything. I am not using KDE or XFCE or any desktop. I need a command line solution.
Where is the best place to put this? I see that some other distros have a /etc/environment and these variables go in there. In Slackware, should I add them as a new file in /etc/profile.d and have them added every time /etc/profile is accessed? Is there a Slackware approved method that I don't know about?

how to set an external static IP address to forward to an internal static IP address. Here is an example:
Linux box (slackware) IP address =
eth0: 10.xxx.xxx.xxx (internal)
eth1: xxx.xxx.xxx.170
eth1.0: xxx.xxx.xxx.171
eth1.1: xxx.xxx.xxx.172
DVR system that I need to forward to: IP address =
xxx.xxx.xxx.251
xxx.xxx.xxx.252
This was all setup by someone else whom I have never spoken with. The IP tables seems to be set up but I cannot provide a screen shot at this time. What I need to do is this. When a user connects to the external static IP address of xxx.xxx.xxx.171 with their DVR software, IP tables will forward to the DVR system at xxx.xxx.xxx.251. The ports desired are 554,555,556, and 557. I know some about Linux but not about IPtables.
I`m running a rather simple iptables script, but no matter what port i try to forward it wont open. Here are the basics:
Code:
ipt="/usr/sbin/iptables"
$ipt -F

I'm running Slackware 13.37 64 bit. I run it on an HP2945SE AMD Turion x2. I am getting an error during boot up unable to enumerate USB device on port 5. It filters throughout the rest of the boot up commands / results. It doesn't seem to matter if things are plugged up to the USB ports or not. Also it doesn't seem to affect anything on the computer. Its just irritating.
