Help with parsing regex in tripwire
We have regex that we use to parse compliance policies in tripwire. can you please help to correct the regex :

policy is "Verify That Exported File Systems Specify the ro (read-only) Option"

the regex is

Code:
^[#].*-o[\ \t]+(?!ro[\ \t]+|ro[=,]\S+|\S+,ro[=,]\S+|\S+,ro[\ \t]+).*$

this does not work. how do we fix it ?

the dfstab looks like this :

Code:
# cat /etc/dfs/dfstab

#       Place share(1M) commands here for automatic execution
#       on entering init state 3.
#
#       Issue the command 'svcadm enable network/nfs/server' to
#       run the NFS daemon processes and the share commands, after adding
#       the very first entry to this file.
#
#       share [-F fstype] [ -o options] [-d "<text>"] <pathname> [resource]
#       .e.g,
#       share  -F nfs  -o rw=engineering  -d "home dirs"  /export/home2

share

share(1M)																 share(1M)

NAME

       share - make local resource available for mounting by remote systems

SYNOPSIS

       share [-F FSType] [-o specific_options] [-d description] [pathname]

       The share command exports, or makes a resource available for mounting, through a remote file system of type FSType. If the option -F FSType
       is omitted, the first file system type listed in /etc/dfs/fstypes is used as default. For  a  description  of  NFS  specific  options,  see
       share_nfs(1M).  pathname is the pathname of the directory to be shared. When invoked with no arguments, share displays all shared file sys-
       tems.

       -F FSType

	   Specify the filesystem type.

       -o specific_options

	   The specific_options are used to control access of the shared resource. (See share_nfs(1M) for the NFS specific options.) They  may	be
	   any of the following:

	   rw

	       pathname is shared read/write to all clients. This is also the default behavior.

	   rw=client[:client]...

	       pathname is shared read/write only to the listed clients. No other systems can access pathname.

	   ro

	       pathname is shared read-only to all clients.

	   ro=client[:client]...

	       pathname is shared read-only only to the listed clients. No other systems can access pathname.

	   Separate multiple options with commas. Separate multiple operands for an option with colons. See .

       -d description

	   The -d flag may be used to provide a description of the resource being shared.

       Example 1: Sharing a Read-Only Filesystem

       This line will share the /disk file system read-only at boot time.

       share -F nfs -o ro /disk

       Example 2: Invoking Multiple Options

       The  following  command shares the filesystem /export/manuals, with members of the netgroup having read-only access and users on the speci-
       fied host having read-write access.

       share -F nfs -o ro=netgroup_name,rw=host1:host2:host3 /export/manuals

       /etc/dfs/dfstab

	   list of share commands to be executed at boot time

       /etc/dfs/fstypes

	   list of file system types, NFS by default

       /etc/dfs/sharetab

	   system record of shared file systems

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

       mountd(1M), nfsd(1M), share_nfs(1M), shareall(1M), unshare(1M), attributes(5)

       Export (old terminology): file system sharing used to be called exporting on SunOS 4.x,	so  the  share	command  used  to  be  invoked	as
       exportfs(1B) or /usr/sbin/exportfs.

       If  share commands are invoked multiple times on the same filesystem, the last share invocation supersedes the previous--the options set by
       the last share command replace the old options. For example, if read-write permission was given to usera on /somefs,  then  to  give  read-
       write permission also to userb on /somefs:

	      example% share -F nfs -o rw=usera:userb /somefs

       This behavior is not limited to sharing the root filesystem, but applies to all filesystems.
