ktupd - A kerberos ticket update daemon
ktupd [ days ]
Ktupd reads a password and then becomes a daemon that updates your ker- beros ticket cache by running kinit once every 3 hours. Ktupd also monitors the ticket cache and detects when it is deleted. If so it recreates the ticket cache. By default ktupd exits after 7 days. With the optional argument it can run up to a maximum of 30 days.
/tmp/krb5cc_UID_XXXXXXXXX The kerberos ticket cache, it is identified by the KRB5CCNAME environment variable. /tmp/krb5cc_UID_XXXXXXXXX.ktupd_output A log of what ktupd is doing. The first lines tells you when it was started and when it will terminate. Then there will be one entry for each time kinit was run. It is removed if ktupd ter- minates normally (by running out of time). /tmp/krb5cc_UID_XXXXXXXXX.ktupd_lockfile A locckfile to prevent more than one ktupd updating the same file.
