transfering file over ssh from c++
Author
I am wondering how i can transfer files over ssh to our server either using c++ or from a command prompt. Currently i just do it manually with winscp3, but i want to automate the copying of certain files from my computer to the server. Thanks for the help.
The putty package has a commandline version of scp (pscp) that I usually use.
I don't know of any ssh libraries you could use but I suspect that you're better off invoking external programs programmatically anyway.
I recommend setting up a simple batch script to do the work, that's the kind of work they were designed to do. Automated password management might be painful though..

so you mean to use a dos batch to call pscp and login and transfer the files. Or does pscp have its own form of a batch file.
To do this in the past, I've used perl with Expect. This works probably only on unix systems, and is a little hacked together.
sub scp{my $experr;my $find;my $buf;my $rtn="";my $cli=shift;my $from=shift;my $to=shift;my $pass=shift;if (!($cli&$from&$to&$pass)){ return 0;}print $cli "scp -q -r $from $to\n";($rtn,$experr,$find,$buf,undef)=$cli->expect(60,"password:","Are you sure you want to continue connecting (yes/no)?");if (!$rtn){ return 0;}if ($rtn==2){ #Then the damned RSA key passing question is up $cli->print ("yes\n"); ($rtn,$experr,$find,$buf,undef)=$cli->expect(20,"password:"); if (!$rtn){ return 0; }}$cli->print ("$pass\n");($rtn,$experr,$find,$buf,undef)=$cli->expect(600, "-re","^.*[\#\>\$]");return $rtn;}Quote:Original post by corrington_jNo, just a regular .bat file. Or your scripting language of choice really..

Uploading a directory (project) should be as easy as this:
pscp -p -r -pw password project user@hostname:project

okay, i figured out how to transfer file, now i need to execute some commands, do i do that with putty?
Quote:Original post by corrington_jTry plink from the putty package. It's got a useful (-m) option for executing commands from a file.

ok, i figured out how to transfer the files, and connect with plink, but i cannot figure out how to execute commands with plink to build my code. heres what i am trying. The last two lines are where i need help. Thanks.
set PATH="C:\Program Files\putty";%PATH%
pscp -p -r -pw pass "C:\*.cpp" "C:\*.h" "C:\make.txt" dbadmin@Vgdb:/home/code/
plink -batch -l dbadmin -pw pass dbadmin@Vgdb
plink cd /home/dbadmin/Code/ImageRecon
plink make -f make.txt
set PATH="C:\Program Files\putty";%PATH%
pscp -p -r -pw pass "C:\*.cpp" "C:\*.h" "C:\make.txt" dbadmin@Vgdb:/home/code/
plink -batch -l dbadmin -pw pass dbadmin@Vgdb
plink cd /home/dbadmin/Code/ImageRecon
plink make -f make.txt
Quote:Original post by corrington_jYou can't repeatedly call plink and expect it to keep the connection, everything has do be done in a single invokation.
plink -batch -l dbadmin -pw pass dbadmin@Vgdb
plink cd /home/dbadmin/Code/ImageRecon
plink make -f make.txt
So either combine both commands with a ";" (plink expects to see them as the last thing on the line, after the connection parameters), or send them through a separate script file with the -m option.

I tried this, but it won't connect now.
plink -batch -l dbadmin -pw pass dbadmin@Vgdb;
cd /home/dbadmin/Code/ImageRecon;
make -f make.txt
plink -batch -l dbadmin -pw pass dbadmin@Vgdb;
cd /home/dbadmin/Code/ImageRecon;
make -f make.txt
