[Ssh-sftp-perl-users] Single channel SFTP connection...

[Stephen N. <st...@st...>]

Hello,

I'm trying to use Net::SFTP against an SFTP-only server (doesn't do SSH 
shell access, only SFTP). The server expects commands on the first 
channel you connect on (channel 0), but whenever I connect with 
Net::SFTP, it always sends commands over a second channel (channel 1). 
This appears to be happening because Net::SSH::Perl opens up a "dummy" 
shell connection on the first channel. Since the SFTP server is waiting 
for commands on channel 0, I can't get any further than authentication.

I've tried commenting out the code in Net::SSH:Perl which opens a 
channel after authentication, in the hopes that Net::SFTP's new 
connection will be channel 0. This works to a point (Net::SFTP's 
connection is indeed channel 0), but as soon as Net::SFTP issues an 
SSH2_FXP_INIT command, the program dies with the following errors:

Use of uninitialized value in numeric gt (>) at 
/usr/local/lib/perl5/site_perl/5.8.1/Net/SSH/Perl/Channel.pm line 85.
Use of uninitialized value in pack at 
/usr/local/lib/perl5/site_perl/5.8.1/Net/SSH/Perl/Buffer.pm line 105.
Connection closed at netsftptest.pl line 22

Connecting to the SFTP server with OpenSSH's SFTP client works 
correctly. The client opens up only the single channel 0 connection, and 
is able to fully connect to the server without a problem.

Is there any way to get Net::SFTP/Net::SSH::Perl to do the same thing?

Thanks in advance!
