Solaris7 交流 -- 重新配置系统核心and write, but not executable permissions. Most programs, but not all, will function correctly, if the default stack permissions exclude executable rights. Attempts to execute code on the stack will kill the process with a SIGSEGV signal and log a message in kern:notice. Program which rely on an executable stack must use the mprotect(2) function to explicitly mark executable memory areas. Refer to the System Administration Guide for more information on this topic. Admins which don't want the report about executable stack can set the noexec_user_stack_log variable explicitly to 0. Also note that the 64 bit V9 ABI defaults to stacks without execute permissions. TCP/IP参数设置 TCP/IP参数可以由ndd工具来设置, Ndd命令能容易的在不重新配置系统内核和重起系统的情况下,修改核心和TCP/IP的设备 的一些参数。使用如下命令可看到相应的帮助。 #ndd /dev/arp \? ?
