[Net-ssh-users] Ruby/Net-SSH - new error when downloading file

Greeting all,



Sorry to send this twice...I just realized I did not put a subject line
(which I find personally annoying).  So I am resending with a subject
line.  Sorry for the redundancy.



I am stumped and I am hoping someone can help me out.  I have been
running into an error when trying to download a file via SFTP.  The
script I am using had been working  until last week.  I am still
searching for anything that might have been updated on my system, but
have had no luck.



This is the error:



$ ./get-sftpfile.rb -srcfilepath /remotedir/file.txt -dstfilepath
/localdir/file.txt

[Net-ssh-users] Ruby/Net-SSH - new error when downloading file

Jeff,

I never had much luck using Net::SSH and then Net::SFTP for file
uploads/downloads.  If it would work for you, you could try a simpler
approach:


-----------------------------------
require ''net/sftp''

Net::SFTP.start(host, user, ...) do |sftp|
  sftp.download source_file, destination_file
end
-----------------------------------

I realize that this doesn''t really help you understand your error, but
it
might help you get the job done anyway.

[Net-ssh-users] Ruby/Net-SSH - new error when downloading file

Kyle,



I just wanted to let you know that I finally managed to get around the
problem by completely removing Ruby from my system and reinstalling.
After that, I tried your suggestion again and it works great.  Thank you
very much!!
