dropbear介绍:

    Dropbear是一个相对较小的SSH服务器和客户端。

编译安装dropbear

[root@centos6 ~]# tar xf dropbear-2013.58.tar.bz2 [root@centos6 ~]# cd dropbear-2013.58[root@centos6 dropbear-2013.58]# cat INSTALL[root@centos6 dropbear-2013.58]# ./configure --prefix=/usr/local/shiyan/ --sysconfdir=/etc/dropbear.conf //报错如下

猜想我们可以没有安装zlib包[root@centos6 dropbear-2013.58]# rpm -q zlibzlib-1.2.3-29.el6.x86_64 //包存在我们可以猜想,由于是源码安装所以可以缺少的是开发包zlib-devel[root@centos6 dropbear-2013.58]# yum list all | grep "zlib-devel"zlib-devel.x86_64    1.2.3-29.el6     base  //存在该包且我们没有安装安装zlib-devel[root@centos6 dropbear-2013.58]# yum -y install zlib-devel.x86_64[root@centos6 dropbear-2013.58]# ./configure --prefix=/usr/local/shiyan/ --sysconfdir=/etc/dropbear.conf[root@centos6 dropbear-2013.58]# make PROGRAMS="dropbear dbclient dropbearkey dropbearconvert scp"[root@centos6 dropbear-2013.58]# make PROGRAMS="dropbear dbclient dropbearkey dropbearconvert scp" install// 根据源码包中INSTALL中定义的[root@centos6 dropbear-2013.58]# ls /usr/local/shiyan/bin  sbin[root@centos6 dropbear-2013.58]# vim /etc/profile.d/dropbear.sh[root@centos6 dropbear-2013.58]# . /etc/profile.d/dropbear.sh[root@centos6 dropbear-2013.58]# cat README

由此可见运行服务需要生成服务器钥匙

[root@centos6 dropbear-2013.58]# dropbearkey -t dss -f /tmp/dropbear_dss_host_key[root@centos6 dropbear-2013.58]# dropbearkey -t rsa -f /tmp/dropbear_rsa_host_key[root@centos6 dropbear-2013.58]# cd /usr/local/shiyan/[root@centos6 shiyan]# lsbin  sbin

测试启动

[root@centos6 ~]#  dropbear -h[root@centos6 ~]# dropbear -d /tmp/dropbear_dss_host_key -r /tmp/dropbear_rsa_host_key -p :12345

测试连接：

[root@centos6 ~]# dbclient -p 12345 root@127.0.0.1
