osx lion – osx change printer ip address without adding new printer – Super User

Posted by jpluimers on 2019/04/29

From [WayBack] osx lion – osx change printer ip address without adding new printer – Super User:

Q

Is there a way to change a printer’s IP address in OSX (Lion) without having to add a new printer? I did find Printer IP Remedy, but was curious if there was an ‘official’ method.

A

You can do this in the CUPS web interface with the following steps:

  1. Open Terminal.app and run cupsctl WebInterface=yes. This enables the CUPS web interface
  2. Open http://127.0.0.1:631/printers in your web browser
  3. Click on the printer you want to change. From the “Administration” drop down, select “Modify Printer”.
  4. Log in with your local admin account
  5. Select the new printer IP either from “Discovered Network Printers” or add it manually with “Other Network Printers”. Make sure that you keep the same connection protocol as it says in “Current Connection” (for me, this was LPD).

Once you’re done with this, Mac OS X will directly print to the new IP address. There is no need to reboot or so. If you want to disable the CUPS web interface again, run cupsctl WebInterface=no.

The CUPS solution works splendid in MacOS as well, so there was no need for [Archive.is] Printer IP Remedy 1.3 free download for Mac | MacUpdate.

Without the CUPS web interface enabled, the web-interface at http://127.0.0.1:631/printers looks like this:

Web Interface is Disabled

The web interface is currently disabled. Run “cupsctl WebInterface=yes” to enable it.

After enabling it like the CUPS web interface wit cupsctl WebInterface=yes, you can see I have the same printer configured multiple times with different communication protocols and output languages:

Printers

Search in Printers:

Showing 6 of 6 printers.

Queue Name Description Location Make and Model Status
OKI_MC342_36855D OKI-MC342-PSO-36855D Office MC342-AirPrint Idle
OKI_MC342_36855D_PCL OKI-MC342-36855D PCL 1060NP-Office Generic PCL Laser Printer Idle
OKI_MC342_IPP OKI-MC342-IPP Office Generic PostScript Printer Idle
OKI_MC342_LPR OKI-MC342-LPR Office Generic PostScript Printer Idle

The first two printers were mapped by DNS, but the last two were mapped by IP address.

Changing the IP address was simple:

  1. Click on each link
  2. Select “Modify printer”
  3. Authenticate (only needed for the first printer change)
  4. For IPP: note the current address (like ipp://192.168.71.52/), then
    1. Choose “Internet Printing Protocol (ipp) “
    2. Click “Continue”
    3. Enter the correct ipp://…./ address (help is at http://127.0.0.1:631/help/network.html or http://127.0.0.1:631/help/network.html?PRINTABLE=YES)
    4. Click “Continue”
    5. Check the modifications (optionally change Description/Location)
    6. Click “Continue”
    7. Keep the driver
    8. Click “Modify printer”
  5. For LPD, note the current address (like lpd://192.168.71.52/), then follow the IPP steps, but choose “LPD/LPR Host or Printer” and enter a valid lpd address.

This is also the place where you can change “Default options”, like paper size (which – for all but the first – somehow defaulted to US Letter 11 inch, while it is actually filled with A4 paper).

At the end, disable the web interface: cupsctl WebInterface=no.

ssh from Mac OS X to ESXi: “WARNING: terminal is not fully functional”

Posted by jpluimers on 2019/03/29

When connecting from my Mac to my ESXi rig, some commands (especially less) show this output:

WARNING: terminal is not fully functional

So I created this alias to connect from my Mac to the internal address of my ESXi rig:

alias ssh-esxi-X10SRH-CF-internal='TERM=xterm ssh -p 22 root@192.168.71.91'

The trick is the bold part: TERM=xterm (which you can also replace by export TERM=xterm; if you want future ssh sessions to use the same [wayback] TERM setting).

The reason is that the Mac defines the TERM variable as containing xterm-256 which is defined on the Mac itself, but ESXi has a hard time coping with it.

Some Mac OS and Xcode combinations had a problem with xterm-256 not being present ([WayBackmacos – Terminal strangeness after installing Xcode on Lion – Super User), but this isn’t the case on my system:

$ ls -alh `find /usr/share/terminfo | grep 'xterm-256color'`
-rw-r--r-- 1 root wheel 3.2K Jul 30 2016 /usr/share/terminfo/78/xterm-256color

On the Mac you really want to use xterm-256color as it looks way better than xterm-color or xterm: [WayBacklinux – What is the difference between xterm-color & xterm-256color? – Stack Overflow (thanks [WayBack] Chris Page!)

It seems I already did something similar on ESXi itself to get esxtop working: ESXi: when esxtop shows garbage. That was on the ESXi side and works as well for this problem too.

However, it is a bit harder to have a script run during ESXi boot time that sets this, so it is easier to fix this on the Mac side.

It works for all OS X and ESXi versions I’ve tested so far.

macOS Sierra: Change the order of the network ports your computer uses to connect

Posted by jpluimers on 2018/10/15

Very useful when you want to give your WiFi less priority than an USB or Thunderbolt network adapter: [WayBack] macOS Sierra: Change the order of the network ports your computer uses to connect.

It is not just that the topmost adapter gets more priority: it also determines the DNS search!

Anyway: after choosing “Set Service Order” on the right, choose the order as seen below.

PS: Since Apple is cleaning up their site, only the above WayBack works, but luckily the below link explains it in a very similar way when using Locations:

Many ways to lock your MacBook

Posted by jpluimers on 2018/07/31

There are [WayBack] 7 ways to lock your MacBook – CNET: When it comes to locking your Mac, you have options.

For now I’ve added the below alias to my ~/.bash_profile which only works if you have “require a password immediately after sleep or screensaver begins”. I have that enabled (with a 5 second delay, not immediate so that when I’m behind my laptop and it starts the screensaver I can still move the mouse or touch a key to keep it awake).

alias sleep-display='pmset displaysleepnow'

PowerShell on Mac OS X and other non-Windows systems

Posted by jpluimers on 2018/07/17

I wasn’t expecting it to be so easy to install PowerShell on Mac OS X:

brew install Caskroom/cask/powershell

In the background it executes this script: https://github.com/caskroom/homebrew-cask/blob/master/Casks/powershell.rb. which indirectly goes through the URL template https://github.com/PowerShell/PowerShell/releases/download/v#{version}/powershell-#{version}.pkg.

On other non-Windows systems, you have to go through GitHub yourself: https://github.com/powershell/PowerShell. The PowerShell team at Microsoft has many more repositories including the Win32-OpenSSH port which you can find through https://github.com/PowerShell.

At the time of writing, PowerShell was available for these platforms:

Platform Downloads How to Install
Windows 10 / Server 2016 (x64) .msi Instructions
Windows 8.1 / Server 2012 R2 (x64) .msi Instructions
Windows 7 (x64) .msi Instructions
Windows 7 (x86) .msi Instructions
Ubuntu 16.04 .deb Instructions
Ubuntu 14.04 .deb Instructions
CentOS 7 .rpm Instructions
OpenSUSE 42.1 .rpm Instructions
Arch Linux Instructions
Many Linux distributions .AppImage Instructions
macOS 10.11 .pkg Instructions
Docker Instructions

The first version I installed on Mac OS X was this: ==> Downloading https://github.com/PowerShell/PowerShell/releases/download/v6.0.0-alpha.17/powershell-6.0.0-alpha.17.pkg

By now I really hope it is out of Alpha state.
