Porteus 4 Porteus.swap file problem [Solved]

[Ed_P]

In running Porteus 4.0 on an old 586 netbook I've added a swap file to the system to speed it up using the instructions found here http://www.porteus.org/faq.html#twenty but booting doesn't accept it saying it has the wrong permissions. How do I add permissions to it? It's on the hard drive which is NTFS format.

please show the file:

Code: Select all

 cat  /etc/fstab

Thank you.

Comment it out:

Code: Select all

#/dev/sda3 /mnt/sda3 ntfs-3g users,noatime,nodiratime,suid,dev,exec,async,comment=x-gvfs-show 0 0

and add this:

Code: Select all

/dev/sda3 /mnt/sda3 ntfs-3g uid=1000,gid=100,dmask=022,fmask=133 0 0

Code: Select all

reboot

Attention! I am not responsible for errors! :-)

Where?

Code: Select all

fstab is recreated automatically during every boot.

I'm sorry. I have another Linux :-(

I've tried chmod 600 /mnt/sda3/Porteus.swap and opening the drive as root and trying to change the drive's Permissions in Nemo but I can not change the Owner or Group to guest. Everything I try reverts Owner and Group back to root. And the Execute option stays at Allow executing file.

Ed_P, Please write the exact error message.

First check how much disk space is where the Porteus.swap is. (on /mnt/sda3 ?). Perhaps there is simply no disk space where Porteus.swap. Free up disk space and try the native instructions from your first message in the topic. But if it doesn't work out for you, try this:


Works for me (Porteus 4.0):

Create swap-file:

Code: Select all

dd if=/dev/zero of=/mnt/sda3/Porteus.swap bs=1024 count=1048576

where 1048576 is 1GB;

Permissions:

Code: Select all

chmod 600 /mnt/sda3/Porteus.swap

Format swap-file:

Code: Select all

mkswap /mnt/sda3/Porteus.swap

and turn on swap:

Code: Select all

swapon /mnt/sda3/Porteus.swap 2>/dev/null

check it out:

Code: Select all

swapon -s

You need to add the file to startup:

Code: Select all

echo "swapon /mnt/sda3/Porteus.swap 2>/dev/null" >> /etc/rc.d/rc.local

Ed_P, Please write the exact error message.

oops, I forgot.

Code: Select all

swapon: /mnt/sda3/Porteus.swap: insecure permissions 0777, 0600 suggested.

I think this was more a warning rather than the show stopper. And I still get it booting but the swap file is working.

Thank you again for your help.

[dZ0TFR]

This is warning, yes. Don't worry

You cut and paste well kitasia. (Interesting that your Posts count shows as 0. )

How do I add permissions to it? It's on the hard drive which is NTFS format.
