centos自带的ssh连接工具不怎么好用，在windows下习惯了securecrt，但是发现securecrt在linux下居然找不到破解版，只能试用方式使用，很不爽。终于找到了这个securecrt的替代软件pac manager。

下载地址：http://sourceforge.net/projects/pacmanager/files/pac-4.0/

我下载的是：pac-4.5.3.5-2.x86_64.rpm

执行命令安装：

rpm -ivh pac-4.5.3.5-2.x86_64.rpm

但是报出如下错误：

error: Failed dependencies:

说明缺了不少的信赖，依次安装。

首先安装 epel 源，这个因为先前我装其它软件的时候装过了，这里就不装了：

# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm<／pre>

安装依赖：

# yum install ftp perl-Crypt-Blowfish perl-Crypt-CBC perl-Crypt-Rijndael perl-Digest-SHA perl-Expect perl-Gtk2 perl-IO-Stty perl-Net-ARP perl-YAML perl-Cairo perl-Glib perl-IO-Tty perl-Pango uuid-perl

perl-Gnome2-GConf perl-Gtk2-Ex-Simple-List perl-Gtk2-GladeXML 这三个包不在源内，下载下来手工安装：

# wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/perl-Gnome2-GConf-1.044-1.el6.rf.x86_64.rpm
# wget http://li.nux.ro/download/nux/dextop/el6/i386/perl-Gtk2-Ex-Simple-List-0.50-13.el6.nux.noarch.rpm
# wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/perl-Gtk2-GladeXML-1.007-1.el6.rf.x86_64.rpm
# rpm -ivh perl-Gnome2-GConf-1.044-1.el6.rf.x86_64.rpm perl-Gtk2-Ex-Simple-List-0.50-13.el6.nux.noarch.rpm perl-Gtk2-GladeXML-1.007-1.el6.rf.x86_64.rpm

以上是网上说的一些信赖，但是我在实际安装的时候，发现还缺少下面的信赖：

perl(Socket6) is needed by pac-4.5.3.5-2.x86_64

perl(Time::HiRes) is needed by pac-4.5.3.5-2.x86_64

telnet is needed by pac-4.5.3.5-2.x86_64

继续安装：

yum install perl-Socket6
yum install perl-Time-HiRes
yum install telnet

安装完成，再继续执行命令：

rpm -ivh pac-4.5.3.5-2.x86_64.rpm

安装成功，可以使用了。

在实际的使用中，发现ssh连接很慢，而且要在connection的proxy中，勾选Never use any proxy for this connection，不然会连接不上，系统中并没有设置代理，原因不明。
