ntp-server.sh does not perform version check correctly

[aekinskjaldi]

ntpd --version from Centos 7 repo gives output to stderr instead of stdout, and thus variable VER remains empty even if version is exactly as mentioned in condition, i.e. 4.2.6p5, and instead of ntpdc command script tries to execute ntpq
Moreover, ntpdc does not resolve localhost correctly and gives error

ntpdc: write to localhost failed: Operation not permitted

I rewrote condition this way to make it work

VER=$($BIN_NTPD --version 2>&1 | head -n 1)
if [[ "$VER" == *"4.2.6p5"* ]]; then
  USECMD=$(echo "$BIN_NTPDC" -c iostats 127.0.0.1)
else
  USECMD=$(echo "$BIN_NTPQ" -c iostats 127.0.0.1)
fi

Looks like it is working properly here for grabbing that version on CentOS 7 under either bash or sh(but both of those working the same is hardly surprising).

[root@elk0]0|/root>sh
sh-4.2# VER=$(ntpd --version 2>&1 | head -n 1)
sh-4.2# echo $VER
ntpd 4.2.6p5
sh-4.2# exit
[root@elk0]0|/root>bash
[root@elk0 ~]# VER=$(ntpd --version 2>&1 | head -n 1)
[root@elk0 ~]# echo $VER
ntpd 4.2.6p5
[root@elk0 ~]# ntpd --version > /dev/null 
ntpd 4.2.6p5
[root@elk0 ~]#

Derp. Sorry. Disregard what I said. I see what you mean now.

Thanks. And aye, you are correct.

Tested and looks good. Thanks!

Made all POSIX happy and merged. Thanks!
