Getting syntax error from interfaces.sh for *nix app

Path Finder

Ubuntu 10.10 / Splunk 4.2.1 / App: *nix 4.2

Yesterday we upgraded to the newest version of Splunk (4.2.1) and upgraded *nix app (4.2). Splunkd is now reporting the following errors:

  • message from "/opt/splunk/etc/apps/unix/bin/interfaces.sh" awk: line 1: syntax error at or near }
  • message from "/opt/splunk/etc/apps/unix/bin/interfaces.sh" awk: line 1: syntax error at or near else
  • message from "/opt/splunk/etc/apps/unix/bin/interfaces.sh" awk: line 1: syntax error at or near ,

I'm unable to identify what the syntax problem is. I've compared the interfaces.sh file on our server to what is posted on the web and they are the same. Is anyone else experiencing this problem?

cyndiback, I don't have a specific fix at this time, but this is a known issue logged as (SOLN-1032). Please submit your own case to support@splunk.com for tracking.

UPDATE: this issue later became SPL-41361, and should be fixed in the next maintenance release of the app. In the meantime, the glorious Vainstein has provided a patch for ifconfig.sh (sorry about the lines wrapping):

# diff interfaces.sh interfaces-mod.sh

<       SPEED=`dmesg | awk '/[Ll]ink( is | )[Uu]p/ && /'$iface'/ {for (i=1; i<=NF; ++i) {if (match($i, /([0-9]+)([Mm]bps)/, array)) {print array[1] "Mb/s"} else { if (match($i,/[Mm]bps/)) {print $(i-1) "Mb/s"} } } }' | sed '$!d'`
<       DUPLEX=`dmesg | awk '/[Ll]ink( is | )[Uu]p/ && /'$iface'/ {for (i=1; i<=NF; ++i) {if (match($i, /([\-\_a-zA-Z0-9]+)([Dd]uplex)/, array)) {print array[1]} else { if (match($i, /[Dd]uplex/)) {print $(i-1)} } } }' | sed 's/[-_]//g; $!d'`

Engager

On debian :
- install gawk
- modify interfaces.sh :
-replace awk by gawk
- modify the line : CMD='ifconfig'. by removing the dot at the end of this line

it works for me after that

we are still having this issue even after upgrading the *nix app to the latest version. anyone?

This is caused by mawk. Debian installs mawk instead of gawk by default. Install gawk instead and the error will go away.

Tried resetting to gawk and rebooted machine...This did not fix the error.

This is working fine on my linux host, and on Solaris for me. 4.2.1 as well.
