help getting sshd to work

[jthorpe6]

Hi,

During the BH presentation, it was shown that the emulator has sshd enabled after a successful restore. Is it possible to provide some instructions to get this working ?

I've completed a successful restore of the emulator, and can interact with it via gdb but doing iproxy 2222 44 on the linux vm and then attempting to ssh on port 2222 to the emulator fails. I've also tried the default port 22 but that fails also.

Thanks

You will need to initialize USB and run Dropbear, similar to this, excluding the micro_inetd part.

Dropbear will need to be added to launchd.plist with sthg like

<key>/System/Library/LaunchDaemons/dropbear.plist</key>
<dict>
            <key>Label</key>
            <string>dropbear</string>
            <key>POSIXSpawnType</key>
            <string>Interactive</string>
            <key>Program</key>
            <string>/usr/sbin/dropbear</string>
            <key>ProgramArguments</key>
            <array>
                <string>/usr/sbin/dropbear</string>
                <string>-i</string>
                <string>-S</string>
                <string>/bin/bash</string>
                <string>-r</string>
                <string>/private/var/dropbear_rsa_host_key</string>
            </array>
            <key>RunAtLoad</key>
            <true/>

            <key>SessionCreate</key>
            <true/>

            <key>Sockets</key>
            <dict>
                <key>DropbearV4Listener</key>
                <dict>
                    <key>SockFamily</key>
                    <string>IPv4</string>
                    <key>SockNodeName</key>
                    <string>127.0.0.1</string>
                    <key>SockServiceName</key>
                    <string>44</string>
                </dict>
                <key>DropbearV6Listener</key>

                    <string>IPv6</string>
                    <key>SockNodeName</key>
                    <string>::1</string>
                    <key>SockServiceName</key>
                    <string>44</string>
                </dict>
            </dict>

            <key>StandardErrorPath</key>
            <string>/dev/null</string>

            <key>inetdCompatibility</key>

                <key>Wait</key>
                <false/>
            </dict>
</dict>

Don't forget to add/generate the host key!

@jthorpe6 Is it possible to write a tutorial that getting sshd to work? thank you!

[jthorpe6]

All I did was what @TrungNguyen1909 said to do, and I did forget to add/generate host keys. Once I added them it all worked fine.
