Ping not working for normal user

Dai_trying · 2015-12-28 21:19

Hi, I have just installed mythtv-frontend to test it on q4os, and am having problems connecting to my backend, I noticed from the logs that :-

A CoreContext mythcontext.cpp:427 (FindDatabase) Cannot find (ping) database host 192.168.XXX.XXX on the network

So I went to console and tried to ping it and was given the error message

ping: icmp open socket: Operation not permitted

Is there a simple fix for this? I need it to work for all users.

Sorry I should have googled first, in case anyone else gets stuck with it the answer is to :-

sudo chmod u+s `which ping`

Something went probably wrong, as 'ping' is always available for ordinary users in Q4OS.

I thought it should have worked, the next time i do a reinstall I will check and see if it works, and if not maybe look into why...
Thanks

I have checked a fresh 1.4.6 installation and 2.0.2 and both are still suffering from this issue, would this be cleared in a future release?

It's only a problem as my memory isn't that good and all I could remember was mythtv had an issue but had to search here to find what it was when installing mythtv-frontend to another pc.

I know it's an easy cli fix here and probably needs quite a bit more work to get it fixed in the installation routines, but I for one would greatly appreciate it. Fingers crossed

We are not able to anyhow reproduce, 'ping' command for normal user goes well as expected.

Fresh Q4OS installation with IP address 10.0.0.5:
$ ping 10.0.0.101
64 bytes from 10.0.0.101: icmp_seq=1 ttl=64 time=0.273 ms
64 bytes from 10.0.0.101: icmp_seq=2 ttl=64 time=0.232 ms

$ ping 127.0.0.1
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.037 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.134 ms

$ sudo ifconfig eth0

We would need to specify exact steps to reproduce this issue to be able to fix it.
Which media did you install Q4OS from ? 'Live CD' or 'Install CD' ?

Reproduced. This glitch is related to Live CD installations, we will take a look and let findings here.

q4osteam · 2016-01-30 17:13

It will be fixed in the next Q4OS release. You can now fix it by this workaround:
$ sudo apt-get --reinstall install iputils-ping

Many thanks

Just done a fresh install with amd64 1.4.7 live-cd and this issue remains...

Dai

q4osteam · 2016-02-19 17:36

Sorry, in the Q4OS-1.4.8 should be finally fixed.
