The message: unauthorized attempt to change login information from 18.xx.xx.xxx probably means that you had invalid Kerberos tickets when your location or login status was being updated on one of the Zephyr servers. Since your Kerberos authentication tickets were not valid, your identity could not be proven and thus the Zephyr server logs the attempt as 'unauthorized'. To refresh your Kerberos tickets, type: renew and type your password when prompted. Then, type: zctl load to reload your zephyr subscriptions. last updated: 7/16/96
