CentOS 7 nprobe start script error

Hello,

Trying to start /etc/init.d/nprobe, i get:

[root@nprobe ~]# /etc/init.d/nprobe start
Starting nProbe ens2f0
/etc/init.d/nprobe: line 26: [.: -gt: unary operator expected

The line in question is the IF statement:

CORE_OFFSET=$(cat /etc/nprobe/nprobe-${INTERFACE_NAME}.conf | grep
"\--cpu-affinity=#ID\+" | cut -d '+' -f 2)
if [ $CORE_OFFSET -gt 0 ]; then

​As i don't have the --cpu-affinity flag on the config, shouldn't it just
proceed ?
I tried adding the --cpu-affinity=0 but the error persists...

Anyone running this successfully in CentOS 7 ?

​Thank you,
Marco

Marco
it works for us but might be that your config file breaks the init script.

Can you please file an issue on https://github.com/ntop/nProbe/issues
and paste the nprobe versione as well the config file?

It's done. I also found some typos on the nprobe manual. Should those be
reported on github also ?
