Re: Net::SSH2 dumping core by syphilis (Archbishop) on Mar 29, 2012 at 01:52 UTC
At what point does the segfault occur ? When Net::SSH2 is loaded ? ... or when new() is called ? ... or when connect() is called ? A few lines down from the top of t/Net-SSH2.t (in the Net-SSH2 source distro) you'll see: `my ($host, $user, $pass) = qw();` [download] Change that to: `my ($host, $user, $pass) = qw(192.168.0.18 user pass);` [download] and then run that script: `perl t/Met-SSH2.t` Perhaps that will help pinpoint when/where the error occurs. Be aware that, having done that, t/Net-SSH2.t now contains your username and password (in plain text) for anyone who opens the file to view. Cheers, Rob	[reply] [d/l] [select]

Hi Rob, Thanks for the reply. The core is dumping when it is trying to connect. See the following output of Net::SSH.t `bash-3.00# perl Net-SSH2.t 1..73 ok 1 - use Net::SSH2; ok 2 - new session isa Net::SSH2 ok 3 - error state clear ok 4 - set banner ok 5 - LIBSSH2_* constants ok 6 - list version match ok 7 # skip version not decimal ok 8 - banner is SSH-2.0-libssh2_1.4.0 ok 9 - poll indefinite ok 10 - poll 1/4 second ok 11 - ->sock is undef before connect Segmentation Fault (core dumped)` [download] Please advice. Thanks, Ashok.	[reply] [d/l]

FWIW, useful information for the developer would be which version of libssh2 you're using, like the output from ldd -v ...auto/Net/SSH2.so	[reply]
