Thanks for the video. I'm a little "old school" for mine. I used an old 1800 series router that I had that was collecting dust. I purchased a card and octopus cable off of eBay and built a Terminal Server. Cisco sells the 8, 16 & 32 port versions of the card. You can find these up for auction all the time.

I've been using the PI console server setup for a little while now for gear setups in area's where we are waiting for fiber to go in or troubleshooting hardware on days we don't want to sit on the floor. Also been using it quite a bit during the pandemic. Its a quick and easy option to a full blown console server.

For those looking at the software Keith was using to connect, it is secureCRT - www.vandyke.com/products/securecrt/ I'm just posting since I wasn't familiar with it. Of course there's good ol' putty as well: www.chiark.greenend.org.uk/~sgtatham/putty/latest.html Or the slightly more useful multi-tab putty from TTY+ : ttyplus.com/multi-tabbed-putty/

Nice idea! I don't need it for my home lab, because I have a router with a 16-port async card installed with connections to all of my console ports. That router has its Ethernet port connected to my home network so I can do just like you did, telnet to the device and reverse-telent to whatever console port I want. I made it a little easier creating aliases for each device name that has the appropriate reverse-telnet command. Great idea though, and I may use it for my home firewall console port access, since it's in another room and not part of the lab. I do have an unused Pi at the moment. Hmmm...

Thank you for the question Ceejay. If we telnet directly to the PI (port 23) there is a password. Not sure about the ability to get a password when connecting to ports 2001, 2002, etc. We can certainly place a password on the console ports of the routers/switches by going to line console 0, specifying a password, and the word "login" there. Happy studies, and thanks for the question.

Hi Keith, I'm curious - since there are USB to console cables, would that work with a USB hub? Is it possible to map USB devices on a common usb hub that you would connect to the USB port on the Raspberry Pi? You can have 8-port USB hubs or even more if necessary.
@KeithBarker

Thank you for the question Amos. The trick is that we need to redirect our connection to specific serial port, and a generic USB hub wouldn't provide that. The USB to 4 serial adapter has specific chips that allow it. I like your thinking!

Cool video Keith! I actually had a Pi3 sitting in my lab room doing only RADIUS stuff for switch practice, and have been using a single roll over from a PC, not even thinking about the Pi! I ended up going with an 8 port version from Amazon: www.amazon.ca/gp/product/B000YB4G2I/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 The StarTech one is bus powered off the Pi3b+ just fine with only 4 consoles hooked up atm, but it also has an option 5VDC power (not included) if needed. The cables are even nicely numbered. I did try minicom in raspbian, which works fine (the ports show up as /dev/ttyUSB0-7), and I also installed the ser2net app. Just a heads up that on debian based distros, like Raspbian (they renamed it I think?), the ser2net package should already be enabled. I did noticed that the first restart didn't work, but the second did. Some helpful commands: restart the service: sudo service ser2net restart check running ports: sudo netstat -tnlp | grep ser2net watch the status/logs: sudo journalctl -u -f or sudo tail -F /var/log/syslog | grep ser2net Note: pi is in adm group by default, and syslog is adm group readible, so sudo isn't needed for /var/syslog grepping! For those looking to "lock down" their Pi from WiFi, either disable WiFi/bluetooth because they don't trust wireless (mgmt consoles should not be on wifi, after all!), or are just looking to setup a simple firewall, here are some tips for blacklisting modules, and installing UFW firewall. Blacklist -------------- This will require a reboot, but it will prevent the broadcom drivers, and thus WiFi/bluetooth, from loading on boot. This command will append (the: | sudo tee -a) the contents of what follows, input from stdin (the
