Solaris7 交流 -- 重新配置系统核心# routed. These packets define the path the packet should take instead # of allowing network routers to define the path. # The default value is 1 (True). # IP_FORWARD_SRC_ROUTED=0 # # ip_ignore_redirect # # This option determines whether to ignore Internet Control Message # Protocol (ICMP) packets that define new routes. If the system is # acting as a router, an attacker may send redirect messages to alter # routing tables as part of sophisticated attack (man in the middle # attack) or a simple denial of service. # The default value is 0 (False). # IP_IGNORE_REDIRECT=1 # # ip_ire_flush_interval # # This option determines the period of time at which a specific route # will be kept, even if currently in use. ARP attacks may be effective # with the default interval. Shortening the time interval may reduce # the effectiveness of attacks. # The default interval is 1200000 milliseconds (20 minutes). # IP_IRE_FLUSH_INTERVAL=60000 # # ip_respond_to_address_mask_broadcast # # This options determines whether to respond to ICMP netmask requests # which are typically sent by diskless clients when booting. An # attacker may use the netmask information for determining network # topology or the broadcast address for the subnet. # The default value is 0 (False). # IP_RESPOND_TO_ADDRESS_MASK_BROADCAST=0 # # ip_respond_to_echo_broadcast # # This option determines whether to respond to ICMP broadcast echo # requests (ping). An attacker may try to create a denial of service # attack on subnets by sending many broadcast echo requests to which all # systems will respond. This also provides information on systems that # are available on the network. # The default value is 1 (True). # IP_RESPOND_TO_ECHO_BROADCAST=0 # # ip_respond_to_timestamp # # This option determines whether to respond to ICMP timestamp requests # which some systems use to discover the time on a remote system. An # attacker may use the time information to schedule an attack at a # period of time when the system may run a cron job (or other time- # based event) or otherwise be busy. It may also be possible predict # ID or sequence numbers that are based on the time of day for spoofing # services. # The default value is 1 (True). # IP_RESPOND_TO_TIMESTAMP=0 # # ip_respond_to_timestamp_broadcast 上一篇:Sun Solaris 用户手册 -- 三.系统安装 下一篇:Solaris7 交流 --- 进程管理、进程控制及cron处理 更多相关文章
