Hello to everyone I wanted to limit my internet speed with terminal commands: sudo ipfw pipe 1 config bw 200KBytes/s sudo ipfw add pipe 1 all from any to any in and that works. But with computer restart that setting is gone, so I have to write it again. And I came to idea to make a deamon that does it. I wrote a file with content: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http:// www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>ipfw</string> <key>Program</key> <string>/sbin/ipfw</string> <key>ProgramArguments</key> <array> <string>/sbin/ipfw</string> <string>/etc/ipfw.conf</string> </array> <key>RunAtLoad</key> <true /> </dict> </plist> and save it on path /Library/Launch Daemons/ipwf.plist and I also made a file /etc/ipfw.conf with content /sbin/ipfw -f -q flush /sbin/ipfw pipe 1 config bw 200KByte/s /sbin/ipfw add pipe 1 all from any to any in /sbin/ipfw -q /etc/ipfw.conf but after computer restart I don't have limitation setting, and ipfw has just a default settings. Can you help me?
