apt-get & proxy

Hi Im currently conected to Internet trough a winproxy, how can i use apt-get?

ooh! ooh! I know the answer to this one!

before you run apt-get (and the rest of your command line) you will want to run the command

export http_proxy="http://your.proxy.name:8080"

replace your.proxy.name with the DNS name or IP address of your proxy, and replace 8080 with what ever proxy port you use in your browser.

My proxy let's ftp traffic out without using the proxy, so I'm not sure what you will need to do if ftp traffic becomes an issue, but let the group know, and I am sure someone can give you some input.

Many thanks for your wise answer :lol: in addition i can use apt-get as follows:

Code:

---

http_proxy=ipoftheproxy:httpport apt-get update

---

many thanks

I believe this should work with modification of the address in the /etc/apt/apt.conf for a more permenant solution.

Code:

---

Acquire::http::Proxy "http://localhost:8000";
Acquire::ftp::Proxy "http://localhost:8000";

---

My proxy requires NT authentication. In addition to the postings, how do I pass the NT authentication to the proxy server?

My company's proxy will not work:

Code:

---

root@ttyp0[knoppix]# export http_proxy=10.162.253.20:80
root@ttyp0[knoppix]# export https_proxy=10.162.253.20:80
root@ttyp0[knoppix]# export ftp_proxy=10.162.253.20:80
root@ttyp0[knoppix]# apt-get update

Can you please help?

you forgot the quotes.

see the previous example, and try that.

> My proxy requires NT authentication.

Try "export http_proxy=http://user:passwd@proxy:port" before apt-get
