修改登陆画面
对本机:先修改文件/etc/issue,改为你要显示的内容.再修改文件/etc/rc.d/rc.local(RedHat)或/etc/rc.d/rc.S(Slackware),把下面几句注释掉:
#This will overwrite /etc/issue at every boot. So, make any change you
#want to make to /etc/iuuse here or you will lose them when you reboot.
echo "">/etc/issue
echo "Red Hat Linux$R">>/etc/issue
echo "Kernel $(uname -r)on $a $(uname -m)">>/etc/issue
cp -f /etc/issue /etc/issue.net
echo >>/etc/issue
不然每次重新启动,/etc/issue都会被更改
对telnet的远程机器:先把文件/etc/usr/sbin/in.telnetd改名,如改为in.telnetd.exe,再编一个名为in.telnetd的shell脚本,在显示完你想显示的内容后再调用in.telnetd.exe
以上是我在一篇文章中看到的.
分析/etc/rc.d/rc.local的内容很容易看出,每次BOOT执行rc.local,其实就是把一些ECHO的内容重定向到/etc/issue,再看看那段E文注释就知道,其实最直接的方法是修改rc.local,象这样:
echo "">/etc/issue
echo "Red Hat Linux$R">>/etc/issue #愿意你就留着
echo "Kernel $(uname -r)on $a $(uname -m)">>/etc/issue #愿意你就留着
echo "你想显示的内容">/etc/issue
cp -f /etc/issue /etc/issue.net
echo >>/etc/issue
这样连issue.net都改了,岂不省事.
另外,/etc/motd(即message of today)在使用者进入SHELL前显示,通常存放系统的最新通知,也可以利用哦.
