SYNOPSISnetselect-apt [OPTIONS] [stable|testing|unstable|experimental|release_codename|sid]
netselect-apt automatically creates a sources.list file for using with apt for the specified distribution by downloading the list of Debian mirrors using wget choosing the fastest servers using netselect, and testing the valid servers using curl (if available). The output file is written to OUTFILE.
The list of fastest servers is determined by checking through netselect, which servers responder faster to ICMP queries. In order to determine if the servers are valid a connectiong using the specificied protocol (HTTP or FTP) is done using curl.
If netselect is not installed setuid, then netselect-apt needs to run as an administrator user (i.e. root). This is only required because the network probes done by netselect requires these permissions. No changes are done to the system.
If -i INFILE is passed netselect-apt uses that rather than downloading another copy to a temporary file. The file will be downloaded from http://www.debian.org/mirror/mirrors_full
- Specify which distribution of Debian to use. By default stable is used.
- -a, --arch ARCH
- Use mirrors containing ARCH. By default the architecture of the current machine is used as reported by dpkg
- -s, --sources
- While generating OUTFILE include also deb-src lines to use with ``apt-get source'' to obtain Debian source packages.
- -i, --infile INFILE
- Use INFILE instead of downloading the mirror list to a temporary file. The file must be in the same format as mirrors_full.
- -o, --outfile OUTFILE
- Use OUTFILE instead of sources.list.
- -n, --nonfree
- Include also non-free section while generating OUTFILE.
- -f, --ftp
- Use FTP mirrors instead of HTTP and generate OUTFILE accordingly.
- -O OPTIONS
- The OPTIONS provided are added, verbatim, to netselect when it is run. Here you can provide a (quoted) list of options for netselect.
- -t, --tests hosts
- Make a short list with the number of hosts provided and use that list to test for mirror validity. By default 10 hosts are tested.
- -c, --country COUNTRY
Only test the sites found under the country
(the value can either be an ISO-3166 value or the full name of the language, in English).
When this value is set the mirror list or the
will be filtered and only the sites that are listed under the given country will be
tested. Note that restricting the search might not give the best results, as
the "fastest" mirror might not even be in the same country as the system the
program is running in.
- setting this to 1 is equivalent to --sources
setting this to 1 is equivalent to --nonfree
LIMITATIONSnetselect-apt is unable to work with restricted environments in which network filtering is implemented as it relies on netselect being able to find a suitable mirror. To do this, the system where the script is run needs to have network visibility of the mirrors, as it will probe them using ICMP probes.
netselect-apt is also unable to work in environments where HTTP or FTP network connections have to be done through a proxy host, as it relies on being able to test the validity of the remote mirrors doing direct network connections to them.
netselect-apt will not check if the mirror it suggests as the "fastest" mirror is either valid or up-to-date. It is recommended that users that use this tool also validate that the mirrors suggested are official mirrors and are also current.
