The Question is:
I need to find a way to change my password in a Unix machine remotely from an
OpenVMS machine without telnet'ing to the Unix machine.
Though unix allows password change only from a telnet session, I could do
something like this from one unix machine to another unix machine by using a
shell script which starts a telnet session in the background to send/receive
the commands and prompts (a
n example in http://tlc.perlarchive.com/articles/perl/ls0001.shtml).
I could install such a script in the targert unix machine and run it with an
rsh command from
VMS. I do not want to do this either.
Thank you very much for any suggestions.
The Answer is :
OpenVMS V7.3 and later provide Kerberos, which could be used as a
basis for this particular distributed authentication task. OpenVMS
V7.1 and later can be configured with LAN Manager authentication,
and the OpenVMS Wizard would expect that at least some UNIX systems
could participate in this -- PATHWORKS, Advanced Server or SAMBA would
likely be involved on OpenVMS, as probably would SAMBA on the UNIX
platform. Other options could include the use of a CGI script on the
target UNIX platform -- preferably accessed via an encrypted http link,
for what should be obvious reasons -- and the use of an http client on
OpenVMS (such as Lynx). OpenVMS can also be configured to participate
in a DCE cell, which may meet your requirements.
For commands and suggestions specific to UNIX authentication and UNIX
distributed authentication options, please contact a UNIX Wizard.
