i am forwarding HTTP request to a internal server, it is quiet successful but access logs donot show the ip of the external m/c. Rather it shows the ip of the machine on which i have enabled port forwarding.

how to redirect all client http request to https request in squid
View 1 Replies View RelatedUsing netcat, nc(1), craft a valid http/1.1 request for getting http headers (not the html file itself!) for the main index page of www dot aalto dot fi. What request method did you use? Which headers did you need to send to the server? What was the status code for the request? Which headers did the server return? Explain the purpose of each header.
nc -v www dot aalto dot fi 8080
HEAD / HTML/1.1

I really don't know what does it mean. Question 2: Using netcat, nc(1), start a bogus web server listening on the loopback interface port 8080. Verify with netstat(, that the server really is listening where it should be. Direct your browser to the bogus server and capture the User-Agent: header "Direct your browser to the bogus server and capture the User-Agent: header" I don't understand this question.
I have a registered domain that resolves (via dyndns) xxx.mydomain.com to my external facing router -easy no issues there. Behind the router I have several machines (some VMs) running webservers, mail etc... What I want to be able to do is redirect the external traffic based on xxx to the relevant internal machine and serve the content back to the external world.
I have tried using a http rewrite of xxx.mydomain.com to the relevant machine an it works fine from within my network, however externally the re-direct fails as the master DNS servers have no record of internal DNS setup in my network (obviously).
So is there anything I can do to get xxx. recognized externally? I'm only just starting to get my head around how DNS, HTTP, TCP etc all hang together. Am I barking up the wrong tree with rewrite? Should I be looking at proxys?
We're having an issue with HTTP POST file uploads on our two Ubuntu PCs. For some reason, whenever one of our users attempts to submit a file in an HTML form, the request times out, usually with a 500 Internal Server Error message. This problem is not limited to one site, but occurs on all sites that use file uploads. Also, the problem does not appear to be with our network, as a Windows 7 PC on the same network can upload files to the same sites without any difficulties. The problem is not browser-specific; we have tested with Firefox, Epiphany, and Google Chrome and all produce the same results. The issue is relatively new, and was first observed within the last month; before this time, both machines had no problems uploading files.
Does anyone have ANY idea what could be causing this? I've tried a number of things, including rebooting the PCs, rebooting the network, disabling IPv6, etc. I'm not very experienced in Linux system administration, but I can use the terminal and am familiar with some terminal-based diagnostic tools, so if you need any additional info or want me to try something, please let me know! I've exhausted my own computer knowledge with regards to finding a solution to this problem.
are there any linux command to have how many http request are sent and received??

I have a question about port forwarding. I have an internal Red Hat server and I would like to use it as a central connection point to some back end servers. This is not an internet router setup. I was thinking I could use iptables and do port forwarding similar to an internet router but internal to internal.
Basically I would like to take any connections to port 22 on server1 interface eth0 and forward them out of interface eth1 to server2 port 22.I am finding a lot of information on port forwarding, but it is all based on using an internet router that is passing through to an internal server. I need to know how to configure a basic linux setup with no existing iptables entries so that I can do this within an existing network.Also, if there is a better or easier approach I would appreciate any direction. I don't want to do this through an SSH tunnel.I know to start I need the following to enable forwarding in the kernel and a firewall PREROUTING rule.
I am setting up a new server with 2 nics installed. Nic0 goes to the firewall and nic1 goes to the internal engineering network.
Problem is Ip forwarding is not working!

Server Name - slick
Firewall Name - gateone
engineering node - crooked
Routing on slick:
From crooked ( which is inside the server (slick) with an ip address of xx.xx.221.249 the only way I can ping or anything outside of the firewall ( gateone) is to turn on IPtables with this configuration:
I don't want to use IPtables. I need the ip forwarding to work.

I then proceeded to setup an configure the Proxy Server, i was able to test and confirm that Squid and Dansguardian Content Filter is working, however i dont know if Clamav is scanning HTTP traffic before it hits the client/server. Is there a way i can check if the Antivirus scanning is working.. is there some log file or real world test i can i can do to confirm that Clamav is scanning incoming traffic or even blocking potential viruses ??

Can anyone here point me to a walk-through or discussion of how to use Webmin to set up port forwarding/NAT on a dual-NIC Centos 5.3 box? The layout will be simple:
Internet --- NIC1 [CentOS Box] NIC2 --- Switch to other PCs
We have a BUNCH of exposed services that are on special ports -- for example, to connect to one machine, you go in with [IP_Address]:12000, and to connect to another, [IP_Address]:12002, etc., etc. We're currently using OpenSuse 10.3 on this box, and YaST makes this criminally easy (you give it the incoming port number and the destination IP/port numbers and it just works). But OpenSuse 10.3 is nearing EOL, we're buying a new machine, and I'd like to use CentOS on the new one.
I've read the sparse Webmin documentation in their Wiki, and it leads one to believe that you simply insert a "NAT" rule. But there's obviously something they're leaving out. I *am* opening the ports in the firewall. But when I log in to [IP_Address]:port, it just times out. The port forwarding never occurs. The test in this case is SSH, and I know that SSHD is working properly because I can log into that machine just fine from another PC on the same internal subnet.

What is this Above Error which I am getting , on my server
I have been beating my head for the last few weeks on this problem, (although I have been taking the wrong approach, it seems).
I need a gateway to direct web traffic to three separate servers/domains. I have been trying to do this with both a dns server and , (seperatly), apache server to forward requests. The dns server was a no go, and <i can only get apache to redirect http and ftp.
After Googling this ALOT, I believe that what I need is a gateway server to redirect my traffic to the 3 different servers. I have been reading about using using nat and iptables for this and was wondering if anyone had any advice/suggestions on this. The other thought I had was to use something like pfSense to create the gateway, but I am still reading the documentation, and I am unsure if this approach will work.
I was able to do on Debian and Ubuntu Servers X applications running on remote servers where I was able to login via SSH. Tried the same with CentOS did not worked. in /etc/ssh/sshd_config

I installed WordPress 3.x on my localhost/Apache server, but I can neither install plugins nor update anything.This happens with both the stable WP3.0 version and the 3.1 beta. When I try to search the Plugin Directory from the WP dashboard, I get this message: An Unexpected HTTP Error occurred during the API request.When I run an update, I get a page asking for the login credentials for the ftp user ("To perform the requested action, WordPress needs to access your web server. Please enter your FTP credentials to proceed. If you do not remember your credentials, you should contact your web host."). Since I'm part of the 'ftp' group on the system, I enter my system login information, click Proceed -- and get a blank page that does nothing.
I've gone to YaST, and I see that the system ftp user has a 6-character password (which may or may not be mine). I'm afraid to change it and risk screwing up other ftp-related functions. I'm running openSUSE 11.3, and am obsessive about updating. I will note that I have an old 2WIRE router that often requires me (including Zypper repos) to enter IP addresses instead of DNS-based URLs to successfully download stuff. Not sure if this is related, but just in case...
