accessing remote file with rsh

siddheshsawant has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks, I am trying to access a remote file situated on machine where the owner of the file is root.I wants to access the content of that file with some predefined function.The code is like this:

#!/usr/bin/perl

BEGIN {
unshift (@INC,"/view/sawans1_api_test/vobs/pp2dev/src/testsuite/user/t
+inc");
unshift (@INC,"/view/sawans1_api_test/vobs/pp2dev/src/testsuite/user")
+;
}

use DHPL::System;
use nightly::common;
use Logs::LogReader;

$file = ` rsh -l root remote_machien cp /nightly_results/2010_03_19/re
+mote_file.log ` ;

    # $file = "/path/remote_file/";

my $sul = SuiteLog->new( { FILE => $file } );  # $logfile is the log f
+ile of test run

$sul->parse_suite( );

# get_scheduled will return the list of all the test_suites present in
+ the respective test_run
foreach my $sname ( @{$sul->get_scheduled( )} ) {

my $scl = $sul->get_log( $sname );
my $name = $scl->name( );
my $result = $scl->result( );
my $errors = $scl->log_errors_short( );
my $description = $scl->get_decription( );

print"Test Suite Name = $name\n";
print"Result = $result\n";
print"Errors = $errors\n";
print"Description = $description\n";

}

If I used my rsh command like this then it is giving an error like this:

Can't open http://lcla238.lss.emc.com/nightly_results/2010_03_19/log_lcla133.lss.emc.com_64___TestSuiteDARE_Prod_MpaaPseudoIBM_AIX__3_19.html: No such file or directory at /view/sawans1_api_test/vobs/pp2dev/src/testsuite/user/tinc/Logs/LogReader.pm line 1344.

If I copied the same logfile to my home directory and then I assign the path of it $file like I have commented in above example then I gets proper out.But I wants to access any such file on the remote host at run time.How to achieve this using RSH??? Remember I have to pass path of that remote file like

$file = "/path/remote_file/"

this and have to access the same file through some pre-defined functions..

Kindly let me know about it...Thanks in advance !!!

You seem to be confused. `http://lcla238.lss.emc.com/nightly_results/2010_03_19/log_lcla133.lss. +emc.com_64___TestSuiteDARE_Prod_MpaaPseudoIBM_AIX__3_19.html` [download] is not something that `cp` understands, usually. Maybe you want to use LWP::Simple to fetch a file via `http://`? Or maybe you want to use `rcp` or `scp` to copy the file from the remote machine to your local machine? I've used the following to read a file on a remote machine as if it were a local file: `open my $remote, "ssh $machine cat '$remote_filename'\|" or die "Couldn't read $machine:$remote_filename: $!/$?";` [download]	[reply] [d/l] [select]

I don't understand what you mean. Maybe show the relevant part of the code you used, and maybe read the rsh documentation on how to pass a user etc.	[reply]
