|
||||
You must install Shorewall and at least one of the compiler packages
|
||||
(you may install them both).
|
||||
|
||||
Problems corrected in 3.9.5.
|
||||
Problems corrected in 3.9.6.
|
||||
|
||||
1) Setting DYNAMIC_ZONES=Yes produced lots of Perl run-time errors in
|
||||
some configurations.
|
||||
1) Placing 'ipp2p' in the PROTOCOL column of configuration files now
|
||||
works.
|
||||
|
||||
2) Invalid rules were generated by LOGALLNEW.
|
||||
2) Previously, '!' in the TEST column of the tcrules file was not
|
||||
handled correctly.
|
||||
|
||||
3) Setting MACLIST_LOG_LEVEL="" and MACLIST_DISPOSITION=ACCEPT or
|
||||
MACLIST_DISPOSITION=REJECT resulted in Perl run-time errors.
|
||||
3) The code generated for copying routing tables from provider file
|
||||
entries was previously incorrect, resulting in run-time errors.
|
||||
|
||||
4) Many more .... (I gave up trying to document them all; check the
|
||||
SVN history if you are interested).
|
||||
4) Previously, using an ipset in a rule would generate invalid
|
||||
iptables-restore input.
|
||||
|
||||
Other changes in Shorewall 3.9.5
|
||||
5) Previously, use of CONTINUE in the tcrules file would cause
|
||||
generation of invalid iptables-restore input.
|
||||
|
||||
1) The Shorewall-perl compiler now validates all log levels. It also
|
||||
validates all protocol names against /etc/protocols and all service
|
||||
names against /etc/services.
|
||||
Other changes in Shorewall 3.9.6.
|
||||
|
||||
In all cases, the iptables-restore input will include the numeric
|
||||
values associated with log level, protocols and services so that
|
||||
iptables-restore doesn't have to convert these names.
|
||||
1) Eariler generations of Shorewall Lite required that remote root
|
||||
login via ssh be enabled in order to use the 'load' and 'reload'
|
||||
commands.
|
||||
|
||||
Beginning with this release, you may define an alternative means
|
||||
for accessing the remote firewall system.
|
||||
|
||||
Two new options have been added to shorewall.conf:
|
||||
|
||||
RSH_COMMAND
|
||||
RCP_COMMAND
|
||||
|
||||
The default values for these are as follows:
|
||||
|
||||
RSH_COMMAND: ssh ${root}@${system} ${command}
|
||||
RCP_COMMAND: scp ${files} ${root}@${system}:${destination}
|
||||
|
||||
Shell variables that will be set when the commands are envoked are
|
||||
as follows:
|
||||
|
||||
root - root user. Normally 'root' but may be overridden using
|
||||
the '-r' option.
|
||||
|
||||
system - The name/IP address of the remote firewall system.
|
||||
|
||||
command - For RSH_COMMAND, the command to be executed on the
|
||||
firewall system.
|
||||
|
||||
files - For RCP_COMMAND, a space-separated list of files to
|
||||
be copied to the remote firewall system.
|
||||
|
||||
destination - The directory on the remote system that the files
|
||||
are to be copied into.
