logging – Where is “/var/log/messages” on mac-osx? – Server Fault

Posted by jpluimers on 2019/07/29

logging – Where is “/var/log/messages” on mac-osx? – Server Fault

TL;DR: because most of it is in /var/log/system.log which is configured in /etc/asl.conf, but the documentation example about syslog.conf never got updated.

Long read

The example in syslog.conf is wrong at WayBack: Mac OS X Manual Page For syslog.conf(5) and man syslog.conf:

EXAMPLES
     A configuration file might appear as follows:
...
     # Log anything (except mail) of level info or higher.
     # Don't log private authentication messages!
     *.info;mail.none;authpriv.none          /var/log/messages
...
FILES
     /etc/syslog.conf  The syslogd(8) configuration file.

It still is when writing this [WayBack]syslog.conf(5) Mac OS X Manual Page, so you have to look at /etc/syslog.conf on a live system:

# Note that flat file logs are now configured in /etc/asl.conf

install.*                       @127.0.0.1:32376

which means the actual configuration is in /etc/asl.conf:

# Rules for /var/log/system.log
> system.log mode=0640 format=bsd rotate=seq compress file_max=5M all_max=50M
? [= Sender kernel] file system.log
? [<= Level notice] file system.log
? [= Facility auth] [<= Level info] file system.log
? [= Facility authpriv] [<= Level info] file system.log

Documentation at [WayBack] asl.conf(5) Mac OS X Manual Page indicates this:

NAME
     asl.conf -- configuration file for syslogd(8) and aslmanager(8)

DESCRIPTION
     The syslogd(8) server reads the /etc/asl.conf file at startup, and re-reads the file when it receives a HUP signal.  The aslmanager(8) daemon reads the file when it starts.  See the
     ASLMANAGER PARAMETER SETTINGS section for details on aslmanager-specific parameters.

Source

Based on [WayBacklogging – Where is “/var/log/messages” on mac-osx? – Server Fault:

Q:

When you read the man pages on Mac OS X, there are references to /var/log/messages, but if you look for the file, it doesn’t exist:

$ ls -l /var/log/messages
ls: /var/log/messages: No such file or directory

A:

2009 era: If you look at the actual /etc/syslog.conf instead of the man page, you see *.notice;authpriv,remoteauth,ftp,install.none;kern.debug;mai‌​l.crit /var/log/system.log

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.

Many Mac OS X / MacOX / whatever versions: Unable to modify the volume with the keyboard – Ask Different

Posted by jpluimers on 2019/02/22

This has happened to me on most Macs with most Apple Mac OS X / MacOS / whatever versions: the built in sound controls for internal speakers and head phones fail to work (keyboard shortcuts and UI both fail).

The solution at [WayBackmavericks – Unable to modify the volume with the keyboard – Ask Different works, but be sure to require the kernel module steps:

open up a Terminal window and run:

sudo killall coreaudiod
sudo kextunload /System/Library/Extensions/AppleHDA.kext 
sudo kextload /System/Library/Extensions/AppleHDA.kext

TigerVNC on Mac OS X with homebrew to check why a Screen Sharing.app connection fails.

Posted by jpluimers on 2019/01/18

Two installation options for TigerVNC:

The [WayBackTigerVNC  viewer gives a bit more details on failing VNC connections than the stock OSX Screen Sharing.app does: after performing the logon, the connection would just stall, but TigerVNC would should  “write broken pipe (32)” after the logon. Most of the linked search results indicated the VNC server was having a state problem.

So I restarted the VNC server, after which connections could be made again in both tools.

I actually prefer the stock Screen Sharing.app as:
