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.

Based on [WayBack]¬†logging – 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‚ÄĆ‚Äčl.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 ([WayBack]¬†macos – 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: [WayBack] linux РWhat is the difference between xterm-color & xterm-256color? РStack 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.

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 [WayBack]¬†TigerVNC¬† 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:

Restoring files from OS X Time Machine with Terminal.app

Posted by jpluimers on 2017/12/01

cd /Volumes/Backup/Backups.backupdb/Joshua\ Priddle’s\ MacBook\ Pro/Latest/Macintosh\ HD/Users/priddle

tmutil restore -v secret_docs.txt ~/

Learned from [WayBack] Restoring files from OS X Time Machine with Terminal.app:

  • do not use cp¬†as it will give you wrong permissions
  • do use tmutil

More elaborate steps (including finding the backup in the first place) is at [WayBack] Commandline restoration of a file in Time Machine on OS X | Hacks for Macs
