Apple tricks

Time machine

• enable network volumes:

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

• create file on shared directory

touch .com.apple.timemachine.supported

• avaho notification for bonjour:

write a file named afpd.service in: /etc/avahi/services

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<!-- Customize this to get a different name for your server in the Finder. -->
<name replace-wildcards="yes">%h server</name>
<service>
<type>_device-info._tcp</type>
<port>0</port>
<!-- Customize this to get a different icon in the Finder. -->
<txt-record>model=PowerMac11,2,Quad</txt-record>
<!-- <txt-record>model=RackMac</txt-record> -->
</service>
<service>
<type>_afpovertcp._tcp</type>
<port>548</port>
</service>

</service-group>

• icons for bonjour, check in this file (better with xcode)

strings /System/Library/CoreServices/CoreTypes.bundle/Contents/Info.plist|less

Bonjour

• list AFP hosts in network

dns-sd -B _afpovertcp._tcp .

• list SSH available hosts

dns-sd -B _ssh._tcp .

example

• ssh to a bonjour host

mac1:~ user$ dns-sd -B _ssh._tcp .
Browsing for _ssh._tcp
Timestamp     A/R Flags if Domain                    Service Type              Instance Name
10:21:16.447  Add     2  4 local.                    _ssh._tcp.                xsysadmin
10:21:16.452  Add     2  4 local.                    _ssh._tcp.                v2_ video edit
10:21:16.458  Add     2  4 local.                    _ssh._tcp.                x’s Mac Pro

• remove spaces with '-' and add .local at the end

mac1:~ user$ ssh v2-video-edit.local

Rsync

1. create /etc/rsyncd.conf (file 1)
2. create /etc/rsyncd.secrets (file 2)
3. create /Library/LaunchDaemons/rsyncd.plist
4. reboot

• file 1 (rsyncd.conf)

[Users]
path = /Users
comment = User files
auth users = backuppc
secrets file = /etc/rsyncd.secrets
hosts allow = 192.168.0.1/32     CHANGE THIS!
strict modes = false
read only = true
list = false

• file 2 (rsyncd.secrets)

backuppc:chosenpassword         CHANGE THIS!

• file 3 (rsyncd.plist)

<?xml version="1.0" encoding="UTF-8"?>

scutil

• scutil is a sort of console for configuration and status of the system (just found out this command, I'll do further documentation)

network behavior

• prevent creating files (like .DS_store apple double atc.) in network mounted shares.

defaults write com.apple.desktopservices DSDontWriteNetworkStores true

name servers

• Purge dns cache ( or empty dns history, clear dns cache)

Leopard
dscacheutil -flushcache

Tiger
lookupd -flushcache

un-hide Library folder

chflags nohidden ~/Library
