The other day I read a blog post by drkhsh about [using fingerd](https://drkhsh.at/2023-05-15_finger.html){target="_blank" rel="noreferrer"} to display contact details in the terminal.
-This looked pretty cool, and is geeky in a retro Unix way, so of course I had to do it as well. While drkhsh's post shows the setup on OpenBSD I am using Devuan so it was a little different. These steps should also work on Debian or any other deb package system.
-install `finger` command on archlinux - netkit-bsd-finger from aur
-port 79
-fingerd
-/home/pyratebeard/finger
+This looked pretty cool, and is geeky in a retro Unix way, so of course I had to do it as well.
+
+You can now finger me remotely! To do so incant
+```
+finger pyratebeard@pyratebeard.net
+```
+
+If you don't have `finger` installed you can also use `nc` (netcat)
+```
+echo pyratebeard | nc pyratebeard.net 79
+```
+
+While drkhsh's post shows the setup on OpenBSD I am using Devuan so it was a little different. These steps should also work on Debian or any other deb package system.
+
+I needed to install the finger daemon, the finger command, and xinetd, which will run the daemon
+```
+sudo apt -y install fingerd xinetd finger
+```
+
+Then created an xinetd service config under /etc/xinetd.d/
+```
+service finger
+{
+ socket_type = stream
+ protocol = tcp
+ wait = no
+ user = nobody
+ server = /usr/sbin/in.fingerd
+ server_args = -u -p /home/pyratebeard/finger
+ disable = no
+}
+```
+
+The `server_args` tell `fingerd` to require a username to finger and use an alternative script, in my case /home/pyratebeard/finger.
+
+The script I point to is what outputs when you finger me
+```
+#!/bin/sh
+cat <<EOF

+ finger ring:
+
+ * drkhsh@drkhsh.at
+

+```
+
+The script has to be executable, then I restarted the xinetd service.
+
+If you try this also make sure port 79 is allowed through your firewall.
+
+A few of us on IRC have now started a "finger ring", so if you think this is fun and want to join in let me know using the contact details on my [homepage](https://pyratebeard.net){target="_blank" rel="noreferrer"}, or now my finger info, or pop onto the #unix channel on unix.chat and post your finger link.
