Introduction
This page contains some tips, tricks and howto's for the plug distro. Feel free to add your own.
Setting the timezone
The timezone is not set on a new plug install (See #757. To set it manually follow the steps below:
- Login as root or su to root.
- choose from /usr/share/zoneinfo which timezone you want to set your plug to.
- Issue the command rm /etc/localtime; ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
- Issue the command hda-php-zone-change "Europe/Amsterdam" to set the timezone for PHP.
Obviously replace Europe/Amsterdam with whatever timezone you want to set the timezone to.
Useful commands
The following useful commands are not installed by default:
- which
- man
- scp
- ssh
- make
To install issue the command:
yum -y install which man openssh-clients make
Advanced
Using the onboard NAND flash as a swap drive
Note that many devices are configured to fallback to booting from NAND flash if no USB/SD card is found. This makes it almost impossible to brick your device.
If you use the NAND flash as swap you will lose this ability.
cfdisk /dev/mtdblock2
- Create a "Linux swap / Solaris" partition that takes all the space:
- remove any existing partitions, if any
- create a new primary partition
- select Type option, enter "82"
- select Write option
- select Quit option
mkswap /dev/mtdblock2 echo "/dev/mtdblock2 swap swap defaults 0 0" >> /etc/fstab swapon -a
Copy a root filesystem from one disk to another
This may be useful if you have set up things on a USB device and want to copy to an internal harddisk:
The code below assumes the old (usb) disk is at /dev/sdb1 and the new (internal) disk is at /dev/sda1. Substitute accordingly
# /dev/sda1 is the target filesystem; must have an empty filesystem on it mount /dev/sda1 /mnt mkdir /mnt2 # /dev/sdb2 is the source filesystem mount /dev/sdb1 /mnt2 cd /mnt2 cp -ar * /mnt
