Hi, dear all, I am rather new to Unix and have this problem where I cant seem to ping from 1 host to another. The scenerio is as follows: -
1 QNX host->Eth->1 SCO host
the SCO host is configured with it's IP
the QNX host is configured with another IP
both in the same domain, ie, 172.20.3.XX... (3 Replies)
The problem I am facing now is that the QNX host could not ping the SCO host and vice versa. They are in the same domain, ie, 172.20.3.xx. As I am very new to Unix, I guess I must have missed out some important steps. Pls help... Thanx alot (2 Replies)

CPAN::Mirrors(3pm) Perl Programmers Reference Guide CPAN::Mirrors(3pm)NAME
CPAN::Mirrors - Get CPAN miror information and select a fast one
SYNOPSIS
use CPAN::Mirrors;
my $mirrors = CPAN::Mirrors->new;
$mirrors->parse_from_file( $mirrored_by_file );
my $seen = {};
my $best_continent = $mirrors->find_best_continents( { seen => $seen } );
my @mirrors = $mirrors->get_mirrors_by_continents( $best_continent );
my $callback = sub {
my( $m ) = @_;
printf "%s = %s
", $m->hostname, $m->rtt
};
$mirrors->get_mirrors_timings( @mirrors, $seen, $callback );
@mirrors = sort { $a->rtt <=> $b->rtt } @mirrors;
print "Best mirrors are ", map( { $_->rtt } @mirrors[0..3] ), "
";
DESCRIPTION
new( LOCAL_FILE_NAME )
continents()
Return a list of continents based on those defined in MIRRORED.BY.
countries( [CONTINENTS] )
Return a list of countries based on those defined in MIRRORED.BY. It only returns countries for the continents you specify (as defined
in "continents"). If you don't specify any continents, it returns all of the countries listed in MIRRORED.BY.
mirrors( [COUNTRIES] )
Return a list of mirrors based on those defined in MIRRORED.BY. It only returns mirrors for the countries you specify (as defined in
"countries"). If you don't specify any countries, it returns all of the mirrors listed in MIRRORED.BY.
get_mirrors_by_countries( [COUNTRIES] )
A more sensible synonym for mirrors.
get_mirrors_by_continents( [CONTINENTS] )
Return a list of mirrors for all of continents you specify. If you don't specify any continents, it returns all of the mirrors.
get_countries_by_continents( [CONTINENTS] )
A more sensible synonym for countries.
best_mirrors
"best_mirrors" checks for the best mirrors based on the list of continents you pass, or, without that, all continents, as defined by
"CPAN::Mirrored::By". It pings each mirror, up to the value of "how_many". In list context, it returns up to "how_many" mirror. In
scalar context, it returns the single best mirror.
Arguments
how_many - the number of mirrors to return. Default: 1
callback - a callback for find_best_continents
verbose - true or false on all the whining and moaning. Default: false
continents - an array ref of the continents to check
If you don't specify the continents, "best_mirrors" calls "find_best_continents" to get the list of continents to check.
get_n_random_mirrors_by_continents( N, [CONTINENTS]
Returns up to N random mirrors for the specified continents. Specify the continents as an array reference.
get_mirrors_timings( MIRROR_LIST, SEEN, CALLBACK );
Pings the listed mirrors and returns a list of mirrors sorted in ascending ping times.
find_best_continents( HASH_REF );
"find_best_continents" goes through each continent and pings "N" random mirrors on that continent. It then orders the continents by
ascending median ping time. In list context, it returns the ordered list of continent. In scalar context, it returns the same list as
an anonymous array.
Arguments:
n - the number of hosts to ping for each continent. Default: 3
seen - a hashref of cached hostname ping times
verbose - true or false for noisy or quiet. Default: false
callback - a subroutine to run after each ping.
ping_cache_limit - how long, in seconds, to reuse previous ping times.
Default: 1 day
The "seen" hash has hostnames as keys and anonymous arrays as values. The anonymous array is a triplet of a "CPAN::Mirrored::By"
object, a ping time, and the epoch time for the measurement.
The callback subroutine gets the "CPAN::Mirrored::By" object, the ping time, and measurement time (the same things in the "seen"
hashref) as arguments. "find_best_continents" doesn't care what the callback does and ignores the return value.
