Using 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
host: www dot aalto dot fi
And it returns:
200 OK
Content-Length: 858
Content-Type: text/html

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 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.

I try use Squid as my proxy server. When I set my firefox to use my proxy server (squid), all is ok, but when I set firefox on another pc (from internet, not local network), all request returned time out turn off my router and connect PC to internet (without router), but still don't work.In iptables is all ok, I think. Where is problem? I think, It isn't problem with squid (because squid don't show error page), but I don't know how fix it
iptables:
Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Edit: SSH from remote pc work fine.

I have recently just got another internet connection at home via cable as well as my exisiting DSL connection. I was wanting all my web browsing that I did via squid to be redirected down the cable connection. The box has a single nic at the moment and the default route sends it via the dsl connection for the mail server that is also running on the box.I was hoping that anything that hit squid would go down the cable connection that is plugged into a router and thus I can route to 172.16.2.251 and everything will go out via cable.
I was reading about iproute2 and marking the packets and is wondering whether this is the way to go?

I need to redirect all http/https/ftp traffic through the remote proxy, but when I changes connection settings in browser or in System->Preferences->Network Proxy it doesn't work well: instead of getting page content browser asks for saving some short (8 bytes) file with the same content for all requested pages. It happens in Chrome/Opera/Firefox. This proxy requires authorization and works on computer with Windos XP. It worked well when I was using Windows 7 and Proxifier, now I have Ubuntu 9.10 with all available updates.

Anyone who has squid proxy server with Clamav configured and its working can share there settings/setup with me and how they tested it ??

I can ssh to my server which is on a LAN accessing the'Net through a Linksys modem/router.I want to be able to configure the Router by using the it's web interface, but the server only has a Command Line Interface and I can only run text browsers like Lynx,hich, although I can log onto the router, the Javascript routines mean that I can't configure the router.I can't access the router's web interface from the 'Net because the router is set up to pass any requests on port 80 to the server.Is there any way I can communicate with the router by sending HTTP requests from my browser external to the LANhaving these relayed to the router by the server and then the server relaying the responses back to my browser.

ettercap can see http request but not response
I'm trying to see regular http responses from my wireless ipad (victim) from my wired pc (attacker). Everything's working great but I can only see the http requests not the responses.
I've done much reading and googling and tried registering in more relevant forums but some forums were shutdown, so I've come here.
Code:
# setup ip forwarding
echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward
# use ettercap to do the mitm using only mitm
sudo ettercap --iface eth0 --text --plugin autoadd --only-mitm --mitm arp:remote /192.168.0.1/ /192.168.0.155/

We have a cisco ASA firewall at work,which redirects all http traffic to our webserver. We have to install a new website ,but it can't be installed to the same server. Setting up a squid reverse proxy can redirect the incoming http requests to the appropriate webserver? If yes, could I get some directions on howto?

When I user wants to navigate through the internet, he must first give his username and password. The password is sent in clear text. I would like to encrypt this using SSL (or an other solution already integrated in Squid). Is this possible in Squid?I read that "user_cert" option can do this, but I couldn't configure it.I have: acl myacl user_cert src 192.168.1.5Which gives: "aclParseAclLine: Invalid ACL type 'user_cert'"The other solution is probably tunneling, but I don't want to install special software on the client machines

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...

i have installed squid 2.6 on my centos. i have writen a shell script to ping a network and write to a file. write '1' if network up and '0' if network down. After that,a perl script will read the file and do the redirection.Perl will redirect to a fix URL [URL] if the network down and do nothing when it up. i have put my perl script in squid.conf at url_rewrite_program /my_file_path.
below is my shell script for pinging:
Quote:
#!/bin/bash
while [ 1 ]
do
HOST=143.148.137.134
[code]....
My problem is client browser are not redirect to www.google.com even the network is down. It should go to the fix URL when the user click any URL in network down situation.it just appear cannot resolve host.

I've been having a hard time googling and trying to get ALL network connection to be redirected to squid proxy. I couldn't find a proper configuration for ufw or iptables. The ideas are:
1. redirection rule should NOT depend on a specific network inteface, but should work with any connection type, ex.: ppp0 or eth0... 2. firewall rules can be for firehol, iptables, or ufw (the same as iptables, just tell me where to place them). Preferably ufw or gufw. 3. should not interfere on cups web interface and lighttpd server.
BTW: it's not a ubuntu server install
