Ok, so I am new with linux. I just pick up a nas that is running some custom version. The first weird thing is that whenever i ssh in it always gives this error.
-bash: ulimit: open files: cannot modify limit: Operation not permitted
next, I cant do anything related to root. Even though I have the password and everything anything I try to do is denied. I cant even write to files!

Edit:
This is what happens when I try anything in root
[admin@******* etc]$ su root
su: must be suid to work properly

Nas is Terramaster t2-220


Please help me

There are a few hits looking up that error.

Solved in Arch Linux-

Sorry, I'm not on a server. HTH

What distribution are you running?

I am running their customize os "TOS" The company is terramaster.

Please post the make/model of your NAS.

Terramaster t2-220

I wasn't able to locate a t2-220 but I did find the TerraMaster F2-220.

I did not read the documentation but I would guess it would not help. Since this is specialized embedded version there probably isn't much we can help you except for contacting Terramaster.

You can reach them at:

Good Luck:-

Ya... I don't think they care, they didnt even finish translating all the the ui, some of it is still in Mandarin. Also I did mean the f2-220.

Had another idea then, I could run a normal distro of linux on it, but idk which one would be the best.

I thought that maybe you missed the f key as it's close to the t key.

Try CentOS it's the rebuild of Red Hat. OR maybe Scientific Linux.

Try running CentOS in a VM first to see if you like it or not.

thing is, It doesnt have video out so i have to install it blind

You can not install a "normal" desktop PC x86/64 distribution. It needs to be compiled for the NAS's architecture/hardware.
