Product Notes for HP-UX Systems

• No support for the NFS/AFS Translator

  AFS does not support use of HP-UX 11.0 machines as NFS/AFS Translator machines.

• Upgrade kernel extensions when upgrading the File Server

  The AFS 3.6 version of the File Server uses the native HP-UX threading package. When upgrading to the new File Server on a machine that previously ran File Server version 3.5 or earlier, you must also upgrade the AFS kernel extensions to the AFS 3.6 version. For instructions on upgrading server and client machines, see Upgrading Server and Client Machines to AFS 3.6.

• Possible lower limit on number of File Server threads

  On some machines, HP-UX reduces the number of threads available to the File Server to fewer than the AFS default of 128. To determine the maximum number of threads available to the File Server (or any single process) on an HP-UX machine, issue the following command:

  % getconf _SC_THREAD_THREADS_MAX

  As on other system types, the HP-UX File Server reserves seven threads for special uses, so the maximum effective value for the fileserver command's -p argument is seven less than the number reported by the getconf command.

• PAM can succeed inappropriately when pam_dial_auth module is optional

  For AFS authentication to work correctly for a service, all entries for the service in the HP-UX PAM configuration file (/etc/pam.conf by convention) must have the value optional in the third field, as specified in OpenAFS Quick Beginnings. However, when you make the login entry that invokes the pam_dial_auth module optional in this way, it can mean that PAM succeeds (the user can login) even when the user does not meet all of the pam_dial_auth module's requirements. This is not usually considered desirable. If you do not use dial-up authentication, comment out or remove the entry for the login service that invokes the pam_dial_auth module. If you do use dial-up authentication, you must develop a configuration that meets your needs; consult the HP-UX documentation for PAM and the pam_dial_auth module.

• HP patch PHCO_18572 enables PAM to change to home directory

  You must install Hewlett-Packard patch PHCO_18572 to enable HP-UX's standard PAM to change to a user's home directory during login. The patch is accessible for download via the UNIX File Transfer Protocol (ftp) at the following address: ftp://hpatlse.atl.hp.com/hp-ux_patches/s700_800/11.X/PHCO_18572 The patch is also available from HP Electronic Support Centers at the following URLs.
