no sudo?

Hi all,
Might be a noob question but.... I previously was able to use sudo to be able to edit files via ssh but no more!
I just get "-ash: sudo: not found"
It might also be related to why I can't assign static IPs anymore they just vanish.
What am I doing wrong?

There is no sudo as it is not required. The entire router runs as root (minus a few processes).
If you aren't able to add static assignments, that's a different issue that we can investigate.

OK but I cant save anything to anywhere. I use vi as my editor and if I try and save i get the message "Read-only file system"
Just then I had a thought that perhaps I am out of space so I tried to delete a large file but I received the message
rm: can't remove 'block.hosts': Read-only file system
There is how much space is left just in case that is the issue:
Code: Select all
root@Gargoyle:/etc# df
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 768 704 64 92% /
/dev/root 6144 6144 0 100% /rom
tmpfs 63040 108 62932 0% /tmp
/dev/mtdblock3 768 704 64 92% /overlay
overlayfs:/overlay 768 704 64 92% /
tmpfs 512 0 512 0% /dev

You're out of space. When the router runs out of space (or gets very close to it) it switches to read-only mode.
You'll need to failsafe reset or re-flash at this point.

I know how to reflash. What is a failsafe reset?

Boots your router into a recovery mode which bypasses any bad configuration. From there you can "firstboot -y" to reset your router to it's initial state post-flash.

OK looks like a reflash!
