In Ubuntu, if you do not like all the information that comes when you do a remote login, then you just need to do this:
duff – description:
Description : Duff is a command-line utility for quickly finding d
uplicates in a
given set of files
and now time to execute :
find . -type f -print0|duff -e0|xargs -0
This will print a list of duplicate files. If you directly want to delete them then you can use them in a rm command directly like ::
rm $(find . -type f -print0|duff -e0)
Now, couple of days back , I setup dnsmasq in NetworkManager but was astonished to see that there was no dnsmasq running. I checked with dig and saw that there was no response from localhost for dns queries. Checked “ps -eaf|grep dns” and found that there was no dnsmasq running. I knew that once you mention “dns=dnsmasq” in the NetworkManager then it should start up but that was not happening. And then I checked audit log, found that some permissions were denied by SELinux.
First check if dnsmasq is indeed having issues because of SELinux:
grep -C 5 sealert /var/log/messages
If you do see something then time to fix it.
grep dnsmasq /var/log/audit/audit.log audit2allow -M mypol && semodule -i mypol.pp systemctl restart NetworkManager
And with this, you should be done, though you might have to repeat this multiple times.
