sshwrap - a ssh wrapper |
| 8 |
|
| 9 |
opens a secure shell connection through a http proxy by using the two fine tools ssh and corkscrew |
| 10 |
|
| 11 |
sshwrap utilizes some Perl modules from CPAN together with common UNIX programs to provide |
| 12 |
a kind of API around the known ssh tools. It started as a standalone solution inside a single Perl script, |
| 13 |
but now uses IPC::Run and Shell.pm to improve modularization and to provide convenient access and functionality. |
| 14 |
|
| 15 |
Another focus is on Linux-/Windows compatibility and - important for this special case - the possibility |
| 16 |
to enter a password on the command line. (other ssh wrappers dictate to use keyfiles instead) |
| 17 |
|
| 18 |
It would be nice to use Net::SSH, Net::SSH::Perl or File::Remote under the hood to dispatch core |
| 19 |
functions to these modules if needed through some circumstances or explicitly requested. |
| 20 |
There has been done work going onto this direction, but as i see for now Net::SSH just works with keys |
| 21 |
and File::Remote is stated to only work on UNIX systems. |
| 22 |
IPC::Run is compatible since it seems to use Win32::Process under the hood. |
