Is this Perl, Bash, CygWin, NetSh, or something that I have
done wrong in the script?
Summary:
========
Two commands run fine from cygwin OR windows shell
prompts but a specific "netsh" command hangs when used
from Perl under CygWin:
net share
netsh ipsec static show all format=table
(ipsec sub-command only runs on Windows 2003)
Also, "netsh interface show interface"
...works correctly from both command line AND
Perl.
[I am leaning on a problem with "netsh" but want the
opinion of the cygwin experts...and if no solution,
perhaps a debug strategy could be suggested.]
Versions:
=========
Cygwin DLL version info: DLL version: 1.5.18
GNU bash, version 3.00.16(11)-release (i686-pc-cygwin)
Perl for Cygwin:
This is perl, v5.8.7 built for cygwin-thread-multi-64int
osname=cygwin, osvers=1.5.18(0.13242),
archname=cygwin-thread-multi-64int
Microsoft Windows [Version 5.2.3790]
Runs from CMD.exe with Perl for native Windows:
Perl v5.8.7 built for MSWin32-x86-multi-thread
Test Script to reproduce:
=========================
The following test script hangs under CygWin Bash and run
to completion under Windows (CMD.exe) -- both command lines
run fine when run from the respective shell prompts (not
in Perl), even when redirected to a file or piped to another
command (more, grep, etc.):
#!/usr/bin/perl -w
open(NETSHARE, "net share |") or die "Can't run net share: $!\n";
print "we got through the call to 'net share'\n";
while (<NETSHARE>) {
print;
}
open(IPSEC, "netsh ipsec static show all format=table |") or die "Can't run
netsh: $!\n";
print "we got through the call to 'netsh'\n";
while (<NETSHARE>) {
print;
}
