SOLVED Linux: ping: socket: Operation not permitted

[NorbertK]

Hello all,
I run ums 10.19.0 under Linux as os-user 'ums' and get the above mentioned error ping: socket: Operation not permitted in the log.
Context is :

Code: Select all

Therefore I have the follwong questions:

• Is ist a good idea at all to run UMSD as a non-root user ?

• Is the error relevant at all ?

• How can the error be prevented ?

[NorbertK]

I found the solution:

Normal users are not allowed to ping..

to change this proceed as written here https://serverfault.com/a/1039895/826330
and amend /etc/sysctl.conf with the follwing line:

Code: Select all

net.ipv4.ping_group_range = 0 2147483647
