Installing Linux into a 286 laptop from the year 1989

befinitiv

Ever wondered what useful things you could do with a 32 year old laptop? Well, this is one option:

In this project I added a Raspberry PI Zero to the insides of the laptop. Both are connected via a serial link and can exchange data via it. You could use this for several applications:

  • Using the 286 with a terminal emulator as an interface to the Linux of the Raspberry PI. This way you can do the typical Linux shell stuff on a retro machine. With this you are quite far up on the hipster level 🙂
  • Connecting the DOS on the 286 to the Internet
  • Transferring files to the DOS filesystem

Terminal emulator

On the 286 side you need to install MS-DOS Kermit: http://www.columbia.edu/kermit/mskermit.html

On the Raspberry side there is nothing to do. So this is really easy to setup.

Connecting DOS to the internet

The setup needed for…

nsx-t password expiration

VMware NSX-T has a preconfigured password expiration policy of 90 days.
Attention you lower your security standards if you never change your password.
Same procedure for nsx-t edge nodes the same.

clear user admin password-expiration
clear user root password-expiration
clear user audit password-expiration



I think it is better you change your password once a year

set user admin password-expiration 365
set user root password-expiration 365
set user audit password-expiration 365

Ubuntu 20.04 mount cifs stale file handle

What a pain in the ass. If you use mount.cifs under Ubuntu 20.04 and now you have stale file handle to edit files and more.

We look in to the manpage from mount.cifs and there is a option to solve this issue.

noserverino Client generates inode numbers itself rather than using the actual ones from the server.

See section INODE NUMBERS for more information.

linux pcie show available slots

Today I had a request from our user for add a PCIe SSD card to a server. One option is you walk to this server and open it. This not the best option to check if it a PCIe slot available.
Another option is use your Linux commandline.

You need your server mainboard manual to see which slot is labeled.

You have only to check under current usage is in use or available.

Confluence alternative

What a incredible e-mail from Atlassian, cloud first. Not everyone wants to use the cloud. I worked with Confluence and Jira over ten years now. Time for alternative Wikis. I am a little bit sad about the cloud first strategy. Confluence and Jira are pretty cool tools.
Time for alternative Wiki´s

https://wiki.js.org/

This Wiki very close to Confluence. But one feature is missing

https://wiki.js.org/feedback/p/multi-sites

Multi Sites

BlueSpice based on MediaWiki but it have a lot more features and a good Editor.

bluespice.com

Multi Sites only available in the enterprise version.

Also look at tiki.org but is more than a wiki

For Jira alternative

I found

ASA Local Authentication Using Active Directory

I had a heck of a time figuring out how to set this up. Cisco’s documentation related to LDAP authentication is all over the place and there isn’t one article that describes just this. If you want to use Microsoft Active Directory to authenticate users locally logging in to the ASA and give them privileged exec access based on a Group, here are the steps.

These steps assume you are using ASDM, but I have attached the CLI equivalents as well.

Prep

  • Create a group in Active Directory that will be used to define access to the ASA. I.e. ASA Admins.
  • Create a service account (password not expiring unless you want to change it in AD and your ASA every month) that will be used by the ASA to bind with AD.

Do it

1. Log in to the ASA with ASDM (CLI steps below)

2. Go to Device…

Mount cif share as user

On Ubuntu you need the cifs-utils

apt-get install cifs-utils

Add the share to the /etc/fstab

//10.10.100.10/blob /mount/share cifs username=john,domain=contoso,noauto,rw,users 0 0

set the correct rights for the local user to the mount share.

sudo mkdir /mount/share
sudo chown -R john:john contoso
sudo chmod -R 774 contoso

Mount the share with mount.cifs

mount.cifs  //10.10.100.10/blob /mount/share 

Don´t use mount -t cifs
