Hi Depti, You can use the openssl command to see how long certificates are valid:
$ openssl x509 -text -in /etc/grid-security/hostcert.pem $ openssl x509 -text -in /etc/depti/globus/usercert.pem $ openssl x509 -text -in /tmp/x509up_u502 I'm not sure but host and user certificates are probably valid for 1 year by default. A proxy credential is valid for 1 day. After one day you have to generate a new proxy credential from your user certificate. After one year you have to generate a new host certificate and a new user certificate. More information about how it works and GSI at all you can find at http://www.globus.org/security/overview.html.
