When logging in with SSH the default shell on these platforms is some vmware specific menu based system. In order to get a real shell you need to type shell. But this is not possible when using sftp, therefore you need to tell your tool to use a real shell.

In WinSCP this is done by configuring the advanced connection parameters for the sftp protocol connection. Press the advanced button and head for the sftp paragraph. In here you need to specify the sftp-server as your shell in the SFTP server text box.
The sftp-server path may change depending on specific version, find the path on your system by running: “find / -name sftp-server”.

On my system the sftp-server was in /usr/libexec/sftp-server. Therefore i had to specify “shell /usr/libexec/sftp-server” as the SFTP-server.

I have a Raspberry Pi that I’m using in different environments. The easiest way to use the Pi is by just connecting power and network and use SSH, but when theres no screen, it’s not always easy to know the IP address of my Pi.

To make life easier for myself i have put the following lines in a start.sh script and added it to my crontab with the @reboot option. This will make crontab run this script every time the Pi has been rebooted (or shut down)

#!/bin/sh
sleep 30
echo “My IP is: $(ip addr | grep global | awk -F ‘ ‘ ‘{print $2}’)” | mail -s “Raspi reporting in…” someone@somewhere.org

The script will put in a 30 seconds delay to allow the Pi to pickup an address and then mail it for my mail address. Remember to make sure that your Pi is able to send mails, otherwise this will not work.

This will most likely ensure that i will get a mail with the IP address of my Pi, and I  am ready to login with SSH.
