想了解使用expect和cvs来给华为设备做配置比较的相关内容吗，在本文为您仔细讲解的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：使用expect和cvs来给华为设备做配置比较，下面大家一起来学习吧。
以前一只用rancid来对cisco的设备做配置比较，但显然rancid对华为不太友好，一直就不支持华为设备（包括h3）。因此呢，由于本人还有点小聪明，知道rancid是考expect和cvs来实现的，于是乎自己写了些比较笨的脚本来给华为的设备做配置比较。
1）去华为设备抓配置
#!/usr/local/bin/expect
spawn telnet x.x.x.x
expect "sername:"
send "xxxx\n"
expect "assword:"
send "xxxx\n"
expect ">"
send "su\n"
expect "assword:"
send "xxxx\n"
expect ">"
send "dis cu\n"
log_file /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
while (1) {
expect {
"More ----" {send " "}
"1>" {
send "quit\n"
exit
}
}
}
2）把配置中的换行符和敏感信息去掉
cd /tmp/rancid.tmp
rm /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
/home/rancid/huawei/d-cp-ne20-1.sh
cd /tmp/rancid.tmp/Distribution/configs
tr -d '\r' < /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/\ \ ----\ More.\{57\}//g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/d\ cipher.\{25\}/d\ cipher\ ******/g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/\ simple.*/\ simple\ ******/g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/local-user\ .*\ /\local-user ***** \ /g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
3）把配置加入rancid的cvs中
cvs add d-cp-ne20-1
cvs commit -m updates
4）把以下内容做成一个文件加入cron就ok了
cd /tmp/rancid.tmp
rm /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
/home/rancid/huawei/d-cp-ne20-1.sh
cd /tmp/rancid.tmp/Distribution/configs
tr -d '\r' < /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/\ \ ----\ More.\{57\}//g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/d\ cipher.\{25\}/d\ cipher\ ******/g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/\ simple.*/\ simple\ ******/g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
sed -e 's/local-user\ .*\ /\local-user ***** \ /g' /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1 > /tmp/rancid.tmp/d-cp-ne20-1.tmp
mv /tmp/rancid.tmp/d-cp-ne20-1.tmp /tmp/rancid.tmp/Distribution/configs/d-cp-ne20-1
cvs commit -m updates > /dev/null
btw：关于cvs在web上的显示，我使用的上viewvc，感觉比cvsweb要好哦。还有，不要说俺的脚本写的很烂，俺是学网络的，脚本这东西，现学现用，凑合了。
