'tiptop' requires root to run

#1 Post by bariumbitmap »

When I run "tiptop", I get this error:

Code: Select all

syscall: Operation not permitted
Could not perform syscall.
Don't know why...
Works fine when run as root. I'm running Jessie on a 64-bit laptop.

Code: Select all

$ uname -a
Linux thinkpad 4.8.0-0.bpo.2-amd64 #1 SMP Debian 4.8.15-2~bpo8+2 (2017-01-17) x86_64 GNU/Linux
I can't reproduce on a 32-bit box, but I can in a 64-bit virtual machine. Should I report a bug?

Code: Select all

tiptop:
  Installed: 2.2-2
  Candidate: 2.2-2
  Version table:
 *** 2.2-2 0

        100 /var/lib/dpkg/status

There is no bug. Looking at the package details (https://packages.debian.org/jessie/utils/tiptop), there are 32bit and 64bit versions of tiptop.

Go ask google before you ask on these boards.

I just checked in a 32-bit virtual machine and got the same thing.

I do not get the error when running as root, but the homepage for tiptop lists "No root privilege needed" as one of the features.

i tried it yesterday, it did not require root privileges (albeit on archlinux, not debian).
but i must say this: i didn't see anything that the normal 'top' utility (or maybe even 'htop') couldn't offer.
or maybe a cli conky.

Problem solved. Workaround for posterity:

Code: Select all

echo 2 | sudo tee /proc/sys/kernel/perf_event_paranoid
