mirrors - measure response times from mirrors
mirrors [ -f file ] [ -n max ] [ -v ] [ -h ]
Mirrors runs fping(1) for each site listed in file to measure the round
trip time of a small ICMP packet. It reports the results in increasing
order of response time (i.e., fastest one first). Smaller response
times give higher download speed.
When mirrors runs it may first give error messages ending "address not
found" meaning your domain name servers could not find the IP address.
Then it gives error messages starting "ICMP Unreachable" meaning the
site did not answer the ICMP echo request. These sites are not in the
final list of response times and FQDN. A large FDQN file like debian
can take several minutes to process. Be patient!
If you do not want messages about any FQDN please edit file in
/etc/mirror/sites/ to remove the undesired FQDN or create your own FQDN
file there with a new name.
-d Display extra messages for debugging.
where file contains the FQDN of the sites compared one per line.
The base directory for file is /etc/mirror/sites/. The default
is to give a help message. You can have a file in
/etc/mirror/sites/ for each archive network you mirror. If file
is not found here mirrors searches the current working
directory. The mirror package includes FQDN list files CPAN,
CTANand debian for the corresponding archive networks. You can
remove a site from mirrors tests by deleting or commenting its
line in file.
-h Displays a short help message.
-n max The number of sites displayed at program end. The default value
-v Display version and copyright information.
The closest and fastest mirror may not be the most up to date and
complete. You must also consider ISP charges in selecting a mirror.
