copied!<p>I think the problem is, that SSH tries to open PTY and it does not work on anything else than PTY for security reasons. This won't work well with pexpect.</p> <p>I have another ssh client:</p> <p><a href="http://www.digmia.com/index.php?option=com_content&view=article&id=54:Digmia%20Enterprise%20SSH&Itemid=56" rel="nofollow noreferrer">http://www.digmia.com/index.php?option=com_content&view=article&id=54:Digmia%20Enterprise%20SSH&Itemid=56</a></p> <p>It's open-source, you can use it. What you are trying to do would be more commands, but you don't need expect at all.</p> <ol> <li><p>First install it accordingly to manual, then do something like this:</p></li> <li><p>Run dssh-agent, add the password you need like this:</p> <pre><code>dssh-add -l < passwordfile </code></pre> <ul> <li><p>or if it is a secure machine, i.e. no one else can log in there, this is <em>very</em> important, otherwise this would be a huge security hole:</p> <pre><code>echo "name-of-server;22;root;password;" | dssh-add -l </code></pre></li> <li><p><code>password</code> file would be something like:</p> <pre><code>name-of-server;22;root;password; </code></pre></li> </ul></li> <li><p>And the do something like (replace <code>CONTENTS OF ...</code> with actual content of that file):</p> <pre><code>dssh root@name-of-server -- echo "CONTENTS OF ~/.ssh/identity.pub" > .ssh/authorized_keys \; chmod og-w .ssh .ssh/authorized_keys </code></pre> <ul> <li><p>You can (optionally) do</p> <pre><code>dssh-add -f passwords </code></pre></li> </ul> <p>(make sure no one else is doing all this stuff, otherwise you would have a race condition).</p></li> </ol> <p>Also, pexpect should probably work with dssh itself (so you don't need to use dssh-agent). But using dssh-agent is simpler and safer.</p> <p>Installation manual for DSSH is contained in the tarball.</p> <p>I don't know any simpler way of doing this, OpenSSH ssh-copy-id is very picky about where the password comes from...</p>
