Perhaps these are two obvious questions: 1) How does one tell which protocol is being used by a particular NFS client? 2) How does one ensure an NFS server is using the TCP rather than UDP protocol? I ask this because we periodically see unrepeatable MD5 checksum errors on our ISO materials, which (when one follows the trail) are located on an NFS "appliance" server. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 *************************************************************************** The information contained in this communication is confidential, is intended only for the use of the recipient named above, and may be legally privileged.
