I am based just outside Nottingham in the East Midlands and can readily provide on-site Linux training courses in Nottingham, Beeston, Castle Donnington, Chesterfield, Derby, East Leak, Grantham, Leicester, Lincoln, Loughborough, Mansfield, Market Harborough, Newark, Sheffield, Stoke on Trent and Sutton Ashfield. Off site training and public linux classes can be arranged in Nottingham and elsewhere in the East Midlands.

City LinUX sample scripts - vn-connect

NAME

vn-connect - start a virtual network connection to remote host.

SYNOPSIS

vn-connect [ -c <config_file> ] [ -d ] [ -v ] <hostid>

AVAILABILITY

vn-connect is a Bourne/Bash shell script which should work equally well on all versions of UNIX and Linux.

DESCRIPTION

The script is designed to be used in support of other utilities such as .IR rhost. The < hostid > is used as the key to look up the connection method and other parameters in the configuration file which are used to make the necessary vn-connection (usually a VPN) either directly to the target host or to a nominated gateway.

OPTIONS

-c <configuration_file> Use the named configuration file in preference to the default " /usr/local/etc/vn-connect.cf ".

-d Set debug mode on. Debug mode uses the -x mode to echo each command to standard error before it is executed.

-v Sets verbose mode. Significant actions are reported to standard error .

EXAMPLES

vn-connect la1

Look up "la1" in the configuration file. If found and a VPN is required use the other parameters found in the "la1" stanza to start a virtual network connection the host or the indicated gateway. Set the route if required.

FILES

vn-connect.cf.

BUGS

The script has very little input error checking.

I started my career in computing in the days of CPM and C/CPM, building network operating systems and correcting bespoke software written to manage community transport booking and accounting systems.

I fist came across UNIX when called upon to migrate database systems from Mercator BBS to Thoroughbred Basic. Excited by the power and flexibility of UNIX in 1989/90 I studied the OS at City University night classes while developing my practical skills in a SCO Xenix environment during the working day.

In 1994 I was introduced to Linux by students in the School of Mathematics and Computing at North London University. Although initially sceptical of the ability of the fledgling OS to meet the requirements of large scale mission critical systems, I rapidly became a convert to Linux in a corporate environment.

I have now worked professionally as a systems manager and systems administrator with Xenix, AIX, HPUX, SunOS, Solaris and Linux in the City, Antwerp, McLean Virginia, Cairo, Birmingham and Nottingham for over 25 years
