sudo: port: command not found

On MacOSX, if you have installed macports with the package installer, you may encounter the sudo: port: command not found problem.

Macports binaries are installed in /opt/local/bin, so you just need to add this path to your PATH environment variable. Example with your user, add to your $HOME/.profile :

export PATH=$PATH:/opt/local/bin

You can source your profile file to update your environment:

$ source .profile

You are now able to use the port command:

$ sudo port -v selfupdate

How to know the maximum RAM supported by your server?

The dmidecode command gives you all informations available about your memory.

With the special parameter “-t 16″, you can see the maximum (physical) memory that your server can have:

$ dmidecode -t 16
# dmidecode 2.8
SMBIOS 2.4 present.

Handle 0x1000, DMI type 16, 15 bytes
Physical Memory Array
Location: System Board Or Motherboard
Use: System Memory
Error Correction Type: Multi-bit ECC
Maximum Capacity: 32 GB
Error Information Handle: Not Provided
Number Of Devices: 8

Here we can see that your server can handle up to 32Gb

Check empty memory slots

To know which slots are used or not use the “-t 17″ flag.

dmidecode -t 17 | grep Size
        Size: 2048 MB
        Size: 2048 MB
