It can just return the fastest for use in automated shell scripts. .PP It uses Time::HiRes for timings and IO::Socket::INET to make a socket connection to the target server, the server response is taken notice of. Unlike some shell scripts it does not rely on 'pings' to measure network speed. .SH "USAGE" .IX Header "USAGE" .IP "\fB\-h\fR" 5 .IX Item "-h" displays usage. .IP "\fB\-q\fR" 5 .IX Item "-q" quiet mode \- only returns the fastest server and prints a progress meter. .IP "\fB\-Q\fR" 5 .IX Item "-Q" very quiet mode \- in addition the progress meter is not shown. .IP "\fB\-r\fR" 5 .IX Item "-r" uses remote CVSup server list from the online FreeBSD Handbook. .Sp If the variable \f(CW$REWRITE_SELF\fR is set to 1 in the script then (as if by magic) it re-writes itself with the new server list. This only works as root and does not do it by default. .IP "\fB\-c country codes\fR" 5 .IX Item "-c country codes" this is a list (comma separated, no spaces) of server groups to time. .Sp FreeBSD servers are grouped into country codes \- see the script or the FreeBSD Handbook for a full list. .Sp NetBSD and OpenBSD servers are lumped together under the 'netbsd' and \&'openbsd' codes respectively. .IP "\fB\-c tld\fR" 5 .IX Item "-c tld" checks the servers in the Top Level Domain. These can be anywhere in the world. .IP "\fB\-c local\fR" 5 .IX Item "-c local" uses the countries specifed in the \f(CW@LOCAL_CC\fR array. Edit the script to specify which countries are considered local. .IP "\fB\-c all\fR" 5 .IX Item "-c all" uses all the FreeBSD servers. This may take some time, but is quite interesting! .SH "EXAMPLES" .IX Header "EXAMPLES" .IP "1" 5 .IX Item "1" times the FreeBSD CVSup servers in the United Kingdom, France and Germany: .Sp .Vb 1 \& $ fastest_cvsup -c uk,fr,de .Ve .IP "2" 5 .IX Item "2" times the OpenBSD and NetBSD CVSup servers: .Sp .Vb 1 \& $ fastest_cvsup -c openbsd,netbsd .Ve .IP "3" 5 .IX Item "3" shell script, finds the fastest \s-1UK\s0 FreeBSD CVSup server, then runs cvsup using that server: .Sp .Vb 4 \& #!/bin/sh \& if SERVER=`fastest_cvsup -q -c uk`; then \& cvsup -h $SERVER /usr/local/etc/cvsup/supfile \& fi .Ve .SH "RETURN VALUES" .IX Header "RETURN VALUES" Returns 0 without any errors, 1 with errors. .SH "AUTHOR" .IX Header "AUTHOR" A.J.Robinson,
