Using Proxy

Verified on Ubuntu Server 12.04, 2013-6-8.

1. Start a goagent server at 10.21.3.31;

2. Login in as root, modify any cn.archive... to us.archive... in /etc/apt/sources.list;

3. Use proxy temporarily: export http_proxy=http://10.21.3.31:8087; Use it permament: add the following line to your /etc/apt/apt.conf(substitute your details for address and port): Acquire::http::Proxy "http://10.21.3.31:8087";

Now you can use apt-get or wget to install something.

Download & Install

RPM-based

Download from a internet-connected host

Get rpm files from cache /var/cache/yum, or use 3rd-party tool yumdownloader:

# yum install yum-utils
# yumdownloader --resolve subversion

Note you can add "--urls" to only list download urls instead of downloading RPMs, it can be used as "dry-run" mode; If yumdownloader can't resolve dependencies properly, see yumdownloader downloads only i686 resolved rpms for solutions.

Instll on a isolated host

# rpm -ivh <package-name>.rpm

Debian-based

aptitude

Notice that 32bit and 64bit of some packages are uncompatible. So you want to download 64bit packages on a 32bit machine, you have to vagrant up a 64bit VM, download deb files and save them in shared folder.

Download

Download package and all its dependencies with aptitude:

`sudo aptitude --download-only install <package-name>`

This will download deb files to /var/cache/apt/archives. Copy the package and all its dependencies to a folder then run sudo dpkg -i *.deb. If you are not sure about which is the related packages, use sudo aptitude clean to remove all existing .deb files before download.

Verified by sudo aptitude --download-only install subversion on vagrant box precise64.

sudo apt-get download <package-name> will download deb files to current directory, since it does not resolve dependencies. So it's not very useful.

Install

`sudo dpkg -i *.deb`

apt-offline

Usage

2. Downlaod data on a internet-connected machine: apt-offline get --bundle mypack.zip -t 5 apt-offline.sig, where mypack is the downloaded archive and "-t 5" means "download with 5 threads";

3. Copy mypack.zip to the offline-machine and extract it: sudo apt-offline install mypack.zip;

4. Install it with sudo dpkg -i <packages>.deb.
