configuring a filtering condition in /etc/pf.d/IP/net0 for interface net0. It may be merged with any
existing filtering conditions. It also has to apply to all the IP network interfaces.
# Don't allow request and reply timestamp of ICMP

Additional Information About File Transfers

This section discusses file naming standard for cross-platform file transfers and how to create
various system files offline for downloading.

DOS and UNIX Filenames

The system's UNIXWARE operating system permits mixed case file names (all upper-case, all
lower-case, or a combination of cases). When transferring UNIXWARE files to a DOS computer
(using ftp or rcp) or exporting files, file names are forced to all upper-case letters. When you
restore these files using a LAN transfer, file names may be forced to lower-case or upper-case,
depending on the particular ftp or rcp software you use. Therefore, advise all personnel creating
files to use fully unique file names; vary the characters, not just the case. Thus, file names
"ACME," "Acme," "acme" are unacceptable, but "ACME1," "Acme2," "acme3" are fine, and
"acme1," "acme2," "acme3" are even better.
