NAME
mirrors - measure response times from mirrors
SYNOPSIS
mirrors
[
-f file
] [
-n max
] [
-v
] [
-h
]
DESCRIPTION
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.
OPTIONS
- -d
-
Display extra messages for debugging.
- -f file
-
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 is 20.
- -v
-
Display version and copyright information.
NOTES
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. Before mirroring a site check its READMEs to see
if mirroring is permitted.
