passwords.
Note that these passwords can be changed after the initial installation by
running the

CAUTION: Do not use operating system commands or utilities to change
these passwords. The
vcx-reconfigure

commands and utilities do not.
VCX File and
Directory Name
Guidelines
VCX systems adhere to file naming conventions based on Linux and UNIX
C shell usage. Files may be created on other platforms such as Microsoft
Windows and then transferred to a VCX system. A valid Windows file or
directory name may not be compatible with VCX Linux conventions. To
ensure that the names of any transferred files are compatible with the
VCX conventions, please use the following guidelines:
■
File and directory names composed of upper and lower case letters,
numbers, hyphens, and underscores are generally valid, but do not
begin a name with a hyphen.
■
File or directory names can range from 1 to 255 characters.
■
File or directory names must not begin with a hyphen or a period.
■
Do not use any of the characters listed in Table 6 in a file or directory
name:
