These types of issues are generally caused by PATH (shell environmental) and file permission issues.

You did not yet provide any user information for either running the script manually or in a crontab; and nor did you provide the environmental variables for the respective users. It matters (the user and the environmental variables).

When you provide that information, the root cause of any issue should start to be more clear.

But please also address gull's line of questioning as well.

Thanks,.

ramond

ramond(8)						      System Manager's Manual							 ramond(8)

NAME

       ramond - IPv6 Router Advertisement MONitor Daemon

SYNOPSIS

       ramond [ -c configfile ] [ -d ]

       ramond -h

DESCRIPTION

       This manual page documents briefly the ramond command.

       ramond is a daemon program monitoring IPv6 router advertisement packets.  When an advert is reveived, a configurable action occurs.

       ramond was designed to "clear" (by sending spoofed zero lifetime adverts) rogue routes sent by users running 6to4 gateways on a campus net-
       work.  Actions are scriptable.  Almost all the available information is passed to a script via environmental variables (see the ENVIRONMENT
       section for details).

OPTIONS

       The program follows the usual GNU command line syntax, without long options.  A summary of options is included below.

       -c configfile
	      Sets the path to the ramond configuration file.  Default is /etc/ramond.conf

       -d     Do not daemonize.

       -h     Show summary of options.

FILES

       /etc/ramond.conf
	      The system-wide configuration file to control the behaviour of ramond. See ramond.conf(5) for further details.

ENVIONMENT

       This section details the environment variables set by ramond when it runs a user-configured script.

       PREFIX The advertised prefix, or null

       PREFIX_LEN
	      The length of the advertised prefix, or null

       SOURCE_ADDR
	      The IPv6 source address of the packet

       SOURCE_MAC
	      The MAC source address of the packet

       INTERFACE
	      The interface which the packet was received on

       ramond.conf(5)
