NAME
netscript-compile - netscript ipfilter-defs compile back end. SYNOPSIS
netcript-compile [ -fhq ] [ -b max-backup-level ] DESCRIPTION
This manual page documents briefly the netscript-compile command from the netscript router/firewall network configuration package. This command is the back end to the netscript compile command documented in netscript(8) manpage. See ipfilter-defs(5) for the details on the definitions files in /etc/netscript/ipfilter-defs. By default it checks to see if the relevant files in the /etc/netscript/ipfilter-defs directory have been updated by comparing their modi- fication times to that of /etc/netscript/ipfilter-defs.conf, and if updating is needed, it recompiles and re-creates the file. Up to max- backup-levels of history are kept of previously compiled /etc/netscript/ipfilter-defs.conf files, with a numeric extention in order of increasing age. OPTIONS
-b max-backup-level Sets the maximum level of backups kept of previously compiled files. This defaults to 2 (see /etc/netscript/netscript-com- pile.conf), and it is also used by the netscript(8) compile command. -f Force compile even though compile file is up to date with definitions. The testing depends on the modification times of the defini- tion file inodes in the file system. -h Show a summary of options. -q Quiet compile. This option suppresses informational progress messages. FILES

NAME
netscript - netscript network configuration command SYNOPSIS
netscript start|stop|reload|restart netscript ifup|ifdown|ifqos|ifreload <interface-name>|all netscript compile [ -fhq ] [ -b max-backup-level ] netscript ipfilter load|clear|fairq|flush|reload|save netscript ipfilter usebackup [ backup-number ] netscript ipfilter exec <function-name1>|<function-name2> [chain p1 p2 ...] netscript ip6filter load|clear|fairq|flush|reload|save netscript ip6filter usebackup [ backup-number ] netscript ip6filter exec <function-name1>|<function-name2> [chain p1 p2 ...] DESCRIPTION
This manual page documents briefly the netscript command from the netscript router/firewall network configuration package. This command is used to configure/reconfigure the interface configuration, ipchains filter setup, and ip route service ( QoS ) setup that are configured in netscript's configuration files. It can manipulate individual interfaces, and reconfigure the iptables filter contents and firewall setup, or reconfigure the QoS setup. It is rather incomplete as it does not describe fully the finely tuned manipulations that happen due to netscript's design which enables a Linux box to serve as a high availability heavy-duty mission-critcial network router or firewall. COMPILE CONFIGURATION MODE
The rules can be compiled and automatically loaded on boot by setting the IPV4_CONFIGURE_SWITCH switch in network.conf(5) to the value of the function used to configure the kernel. Net-compile(8) creates this function as 'Configure'. If this switch is set, the netscript startup will run netscript-compile(8) to make sure everything is up to date and load the rules from /etc/netscript/ipfil- ter-defs.conf, and the relevant settings in network.conf(5) which are used to establish packet grooming and configure the built in ker- nel netfilter INPUT and FORWARD chains in the filter table. If compilation fails, the previous rule set is not replaced and it is used instead. A similar mode exists for IPv6, but it is not fully implemented yet. IPTABLES CONFIGURATION MODE
This configuration mode corresponds to the old method of doing it using iptables-save(8) and iptables-restore(8). This is the default for operation, and occurs if the IPV4_CONFIGURE_SWITCH is not set in network.conf(5). This is the metoh still used by IPv6 as well. OPTIONS
start Set up networking configruation by loading ipcahins filters, setting up bridge, configuring interfaces and running any configured lower layer protocol daemons or commands. For use from a startup script. stop Shut everything down. For use from a startup script. reload Refresh the setup of netscript except for iptables from the configuration files in /etc/netscript restart|force-reload Stop everthing and then start everything again. For use from a startup script. ifup <interface-name>|all Bring interfaces(s) up by starting any protocol daemons, and configuring interfaces. ifdown <interface-name>|all Shutdown said interface(s) by doing reverse of ifdown. ifqos <interface-name>|all Reload QoS configuration for interface(s). ifreload <interface-name>|all Refresh the interface setup and implement any configuration changes. ifreset <interface-name>|all Shutdown and then restart interface(s), reloading configuration from lower layer up to the network layer. compile [ -fhq ] [ -b max-backup-level ] Compile the new definitions in /etc/netscript/ipfilter-defs directory into a new set of functions in the /etc/netscript/ipfilter- defs-compiled.conf file. See the netscript-compile(8) and ipfilter-defs(5) manpages for details. ipfilter load|reload Load/reload the IPv4 iptables filters and reconfigure the firewalling, from that saved in /etc/netscript/iptables (via iptables- restore(8) ), and the QoS fair queuing setup, or by excuting the requisite configuration function from /etc/netscript/ipfilter-defs- compiled.conf if using ipfilter-defs(5) mode. ipfilter save Save the IPv4 iptables configuration to /etc/netscript/iptables via iptables-save(8) , after backing it up to /etc/netscript/ipta- bles.1 and cycling the previous backup files down through the configuration history. This does not work if the IPv6 side of netscript is operating in ipfilter-defs(5) mode. ipfilter usebackup [ backup-number ] Restore setup from the IPv4 iptables backup configuration from /etc/netscript/iptables.n ( default 1 ) via iptables-restore(8), or if the ipfilter-defs(5) backend is used, the requisite backup number from the /etc/netscript/ipfilter-defs.conf history files. ipfilter clear|flush Remove iptables and any firewall setup, and if IPV4_FWDING_KERNEL is set to FILTER_ON (see network.conf(5) ), disables all IPv4 packet forwarding on the router. Very useful for debugging protocol problems on a firewall by enabling a reasonably safe check to be made with the filtering down. ipfilter forward|fwd Turns on the IPv4 kernel forwarding switch manually. This is irrespective of the setting of IPV4_FWDING_KERNEL (see network.conf(5) ). Use with caution as it will allow traffic through the box. ipfilter noforward|nofwd Turns off the IPv4 kernel forwarding switch manually. This is irrespective of the setting of IPV4_FWDING_KERNEL (see net- work.conf(5) ). Use with caution as it will cut off reachability. ipfilter fairq Reload the IPv4 fairq chain that marks the packets for the QoS interface transmit queues. ip6filter load|reload Load/reload the IPv6 iptables filters and reconfigure the firewalling, from that saved in /etc/netscript/ip6tables (via ip6tables-restore(8) ), and the QoS fair queuing setup, or by excuting the requisite configuration function from /etc/netscript/ipfilter-defs-compiled.conf if using ipfilter-defs(5) mode. ip6filter save Save the IPv6 iptables configuration to /etc/netscript/iptables via ip6tables-save(8) , after backing it up to /etc/netscript/ip6tables.1 and cycling the previous backup files down through the configuration history. This does not work if the IPv6 side of netscript is operating in ipfilter-defs(5) mode. ip6filter usebackup [ backup-number ] Restore setup from the IPv6 iptables backup configuration from /etc/netscript/ip6tables.n ( default 1 ) via ip6tables-restore(8), or if the ipfilter-defs(5) backend is used, the requisite backup number from the /etc/netscript/ipfilter-defs.conf history files. ip6filter clear|flush Remove IPv6 iptables setup, and if IPV6_FWDING_KERNEL is set to FILTER_ON (see network.conf(5) ), disables all IPv6 packet forward- ing on the router. Very useful for debugging protocol problems on a firewall by enabling a reasonably safe check to be made with the filtering down. ip6filter forward|fwd Turns on the IPv6 kernel forwarding switch manually. This is irrespective of the setting of IPV6_FWDING_KERNEL (see network.conf(5) ). Use with caution as it will allow traffic through the box. ip6filter noforward|nofwd Turns off the IPv6 kernel forwarding switch manually. This is irrespective of the setting of IPV6_FWDING_KERNEL (see net- work.conf(5) ). Use with caution as it will affect reachability. ip6filter fairq Reload the IPv6 fairq chain that marks the packets for the QoS interface transmit queues. FILES
