FPing Continuous 100% Packet Loss #109

Closed MHammett closed 3 years ago

MHammett commented 6 years ago

My graphs are showing 100% packet loss. I stopped the smokeping service and ran smokeping --debug and saw this:

FPingContinuous: Executing /usr/bin/fping -l -B1 -r1 -p 950 -b5000 -t1500 -p1500 -S50.31.0.191 -O0x20 XXX.XXX.XXX.XXX ZZZ.ZZZ.ZZZ.ZZZ YYY.YYY.YYY.YYY FPingContinuous: No data exists - returning undef

I run that command and I get data. root@smokeping:/usr/share/perl5/Smokeping/probes# /usr/bin/fping -l -B1 -r1 -p 950 -b5000 -t1500 -p1500 -S50.31.0.191 -O0x20 XXX.XXX.XXX.XXX ZZZ.ZZZ.ZZZ.ZZZ YYY.YYY.YYY.YYY XXX.XXX.XXX.XXX : [0], 4096 bytes, 2.69 ms (2.69 avg, 0% loss) ZZZ.ZZZ.ZZZ.ZZZ : [0], 4096 bytes, 2.91 ms (2.91 avg, 0% loss) YYY.YYY.YYY.YYY : [0], 4096 bytes, 14.5 ms (14.5 avg, 0% loss) XXX.XXX.XXX.XXX : [1], 4096 bytes, 2.49 ms (2.59 avg, 0% loss) ZZZ.ZZZ.ZZZ.ZZZ : [1], 4096 bytes, 2.69 ms (2.80 avg, 0% loss) YYY.YYY.YYY.YYY : [1], 4096 bytes, 12.9 ms (13.7 avg, 0% loss) XXX.XXX.XXX.XXX : [2], 4096 bytes, 2.44 ms (2.54 avg, 0% loss) ZZZ.ZZZ.ZZZ.ZZZ : [2], 4096 bytes, 2.61 ms (2.73 avg, 0% loss) YYY.YYY.YYY.YYY : [2], 4096 bytes, 12.7 ms (13.4 avg, 0% loss) XXX.XXX.XXX.XXX : [3], 4096 bytes, 2.23 ms (2.46 avg, 0% loss) ZZZ.ZZZ.ZZZ.ZZZ : [3], 4096 bytes, 2.70 ms (2.72 avg, 0% loss) YYY.YYY.YYY.YYY : [3], 4096 bytes, 11.1 ms (12.8 avg, 0% loss)

@MHammett which version of fping are you using? and under which distro/release?

if you run this, do you see the same output as me?

root@debian-9-amd64:~# getcap $(which fping)
/usr/bin/fping = cap_net_raw+ep

if not, try setcap cap_net_raw+ep /usr/bin/fping (e.g. as recommended in #112 for a different symptom)

I see the same. Additionally at the bottom of the --debug run I also see

FPingContinuous: Input pipe has been closed - exiting
lelutin commented 5 years ago

@s1shed I think the same questions that I asked @MHammett would also apply to your case:

which linux distribution are you using? which release of the distro? what versions of smokeping and fping are you using?

also, if you run getcap $(which fping) do you see that it has the cap_net_raw+ep capability?

Hello,

I'm having a similar issue.

Distro Debian 10.3.

getcap $(which fping) /usr/bin/fping = cap_net_raw+ep

I'm not sure why I ghosted the thread. I'm having the same problem again.
