Hi Michael!!, How are you?. El dom, 27-09-2009 a las 15:51 +0200, M. Boelen escribió: > Hi Francisco, > > I tried to test this issue with my Ubuntu setup. By default /bin/sh is > linked to /bin/dash. However, no issues under Ubuntu.
In Ubuntu /bin/sh is linked to /bin/dash, so if you execute:
ubu...@ubuntu:~$ sh
$ echo -e "Hello"
-e Hello
$
But, If you execute:
ubu...@ubuntu:~$ sh
$ /bin/echo -e "Hello"
Hello
$
This way Lynis works fine in Ubuntu, but it fails in Debian because the
Display function in include/functions execute:
case ${OS} in
"MacOS") ECHOCMD="echo" ;;
"Solaris") ECHOCMD="echo" ;;
"Linux")
case ${LINUX_VERSION} in
"Ubuntu") ECHOCMD="/bin/echo -e" ;;
*) ECHOCMD="echo -e" ;;
esac
....
The problem will be fixed changing 'ECHOCMD="echo -e" ;;' by
'ECHOCMD="/bin/echo -e" ;;'.
Or apply the bit complex patch attached in diff file (probably
unneeded).
Or maybe just removing the LINUX_VERSION check (beware with other
distributions).
Please, patch it as you prefer in the next lynis release, or
I could patch it provisionally in Debian.
Thank you for your work.
Best regards,
Francisco.
