修改登陸畫面
對本機:先修改文件/etc/issue,改為你要顯示的內(nèi)容.再修改文件/etc/rc.d/rc.local(RedHat)或/etc/rc.d/rc.S(Slackware),把下面幾句注釋掉:
#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 $(uname -m)">>/etc/issue
cp -f /etc/issue /etc/issue.net
echo >>/etc/issue
不然每次重新啟動,/etc/issue都會被更改
對telnet的遠(yuǎn)程機器:先把文件/etc/usr/sbin/in.telnetd改名,如改為in.telnetd.exe,再編一個名為in.telnetd的shell腳本,在顯示完你想顯示的內(nèi)容后再調(diào)用in.telnetd.exe
以上是我在一篇文章中看到的.
分析/etc/rc.d/rc.local的內(nèi)容很容易看出,每次BOOT執(zhí)行rc.local,其實就是把一些ECHO的內(nèi)容重定向到/etc/issue,再看看那段E文注釋就知道,其實最直接的方法是修改rc.local,象這樣:
echo "">/etc/issue
echo "Red Hat Linux$R">>/etc/issue #愿意你就留著
echo "Kernel $(uname -r)on $a $(uname -m)">>/etc/issue #愿意你就留著
echo "你想顯示的內(nèi)容">/etc/issue
cp -f /etc/issue /etc/issue.net
echo >>/etc/issue
這樣連issue.net都改了,豈不省事.
另外,/etc/motd(即message of today)在使用者進入SHELL前顯示,通常存放系統(tǒng)的最新通知,也可以利用哦.
