using wget

wget is a very good utility to download large files or iso images.
When downloading large file or DVD iso, you can use wget -c ‘url to iso file’ which you can resume download from where you left last time.

Sometimes there are scuh links which keep a lot of garbege, and using wget -c ‘url to iso file’ causes a new thread a new download instead of resuming.
In such a case you can use wget -c ‘url to iso’ -O my-dvd.iso

Using -O file name downloads file with file name and always can be resumed.

On the machine behind the blocked ports:

Download hamachi for linux.

I have hamachi-0.9.9.9-20-lnx.tar.gz

• Uncompress tar file with
  tar zxvf hamachi-0.9.9.9-20-lnx.tar.gz -C /usr/src/
• Change directory
  cd /usr/src/hamachi-0.9.9.9-20-lnx/
• Install hamachi
  make install
• Run tuncfg command
  tuncfg
• Generate crypto identity
  hamachi-init
• Start hamachi daemon
  hamachi start
• Put hamachi daemon online
  hamachi login
• Create hamachi network
  /usr/bin/hamachi create myHamNetwork password
• Now become online in created network
  /usr/bin/hamachi go-online myHamNetwork

  Follow these steps on the machine from which you want to connect to the blocked machine:
