* Work around Solaris' /bin/sh not being POSIX. If /usr/xpg4/bin/sh is present, we are (definitely?) on Solaris or a derivative, and /bin/sh cannot be trusted to support POSIX, but /usr/xpg4/bin/sh can be. Exec it right away. * Work around Solaris 'which' command oddity. Solaris' (at least) 'which' command outputs not-found errors to STDOUT instead of STDERR. This makes "did we get any output from which" checks insufficient; piping to grep -v the "no foo in ..." message should work. Note that this patch set includes all such uses of which that I could find, including ones that should never be reached on Solaris (i.e. only executed on some other OS) just for consistency. * Improved alternate-sh exec to avoid looping. * Solaris' /usr/ucb/echo supports -n. * Check for the best hash type that openssl supports. When using openssl to generate hashes, do not assume it supports sha256; try that, then sha1, then give up and use md5. * Solaris does not support sed -i; use a tempfile. * Use the full path for modinfo. When running as non-root, /usr/sbin/ might not be in PATH. include/tests_accounting already calls modinfo by full path, but include/tests_kernel did not. * Solaris find does not support -maxdepth. This mirrors the logic already in tests_homedirs. * Use PSBINARY instead of ps. * Work around Solaris' date not supporting +%s. Printing nawk's srand value is a bizarre but apparently once popular workaround for there being no normal userland command to print UNIX epoch seconds. A perl one-liner is the other common approach, but nawk may be more reliably present on Solaris than perl. * Revert to using sha1 for HOSTID. * Whitespace cleanup for openssl hash tests.

######################################################################
|
|
#
|
|
# Options:
|
|
# ---------
|
|
# 1) lynis update info - Show version information (external)
|
|
# 2) lynis update release - Check and install new release (internal)
|
|
#
|
|
# How to use:
|
|
# ------------
|
|
# Run option 1 to know about current and latest release information.
|
|
# Run option 2 to query internal server for possible upgrade of Lynis.
|
|
#
|
|
# Steps for updating to new release:
|
|
# 1) Run Lynis with: lynis update release
|
|
# 2) Lynis will use this helper and check the profile
|
|
# 3) The configured web server will be queried (lynis-latest-version)
|
|
# 4) The contents of this file will be compared with a local file
|
|
# 5) If there is a difference, download package
|
|
# 6) Check paths and extract files
|
|
# 7) Quit program
|
