View 1 RepliesUsing 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

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 want to redirect the packet to proxy server. can u help me.
Present network.
MY internal network ==> switch ==> proxyserver ==> router ==> internet.
(for internet i use

What i want is
My internal network ==> getway or firewall ==> switch ==> proxy server ==> router==> internet. ( where this getway or firewall i can configure for forward http request to proxy server.)
so that i can separate my internal network from intranet but able to access the internet.
help me out

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.

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/

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 want to ENABLE SSL on a PORT 2222 :
Now this works fine. But I also want the HTTP URL to work and redirect it to HTTPS.
When I visit http://IP:2222 I get :

Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

I got a request today from someone on the software development team that reads as follows: Quote: According to RFC 4409 client mail submission to an email server is supposed to use port 587. Server to server SMTP relays are to use port 25. When I am not on site, I can't email via my work account via my iPhone or my residential internet because my ISP(s) filter port 25 to only allow traffic to and from their mail servers. They do however allow 587 anywhere per RFC 4409. Just to send this email I am having to relay off my own server in California. get the proper ports opened on the mail server?

1. Allow inbound/outbound www packets (works!)
2. DROP inbound traffic to port 80 from source ports less than 1024. (DOES NOT WORK!)
Now, technically, when i use hping to test my rules, hping3 192.168.100.100 -S -p80 -s 1023 I should NOT receive any packets. However, i still receive packets, which means my rule that says less than 1024 does not work. (see below)
