Ubuntu10SSH2协议安装

SSH2是一套安全通讯协议框架(早期的SSH1由于存在安全漏洞,现在已经不用了),基于SSH2协议的产品目前主要有opensshputtySSH Secure Shell Client等。安装了SSH2后,我们就可以通过Secure CRT连接服务器了。ubuntu10默认安装openssl.

检查和安装ssh

dpkg --list|grep ssh

//如果有openssh-client openssh-server,就不再需要再安装了

//如果openssh-server没有安装,可输入以下命令:

sudo apt-get install ssl

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://cn.archive.ubuntu.com lucid-updates Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key

W: Failed to fetch http://cn.archive.ubuntu.com/ubuntu/dists/lucid-updates/Release

W: Some index files failed to download, they have been ignored, or old ones used instead.

报错了,GPG和源的问题.

//网上的解决办法,但是我的无效。

sudo aptitude -o Acquire::http::No-Cache=True -o Acquire::BrokenProxy=true update

//多方查找,在国外的网站上找到方法。

guangbo@guangbo-laptop:~$ sudo apt-get clean

guangbo@guangbo-laptop:~$ cd /var/lib/apt

guangbo@guangbo-laptop:/var/lib/apt$ sudo mv lists lists.old

guangbo@guangbo-laptop:/var/lib/apt$ sudo mkdir -p lists/partial

guangbo@guangbo-laptop:/var/lib/apt$ sudo apt-get clean

guangbo@guangbo-laptop:/var/lib/apt$ sudo apt-get update

//重新安装

sudo apt-get install ssl

//查看是否安装成功

dpkg --list|grep ssh

检测并启动ssh

ps -ef|grep openssl

//如果有openssl字眼,则表明已启动。

sudo /etc/init.d/ssh start

[sudo] password for guangbo:

其它修改

至于更新源,我其实先更新下面的文件。但是未生效,于是有上面的方法。如果上面的方法生效,下面的请直接无视。

I'm also have the same problem... after googled for sometimes, I have finally found the solution here
just edit

Quote:

/etc/resolv.conf

and put this at the top of it

Quote:

# google nameservers
nameserver 8.8.8.8
nameserver 8.8.4.4

Quote:

sudo apt-get update

hope it will help

SecureCRT连接测试

//请确保ubunto10已启动ssh2协议,端口22.

sudo /etc/init.d/ssh start

SecureCRT配置

连接成功
