How to install ssh on Solaris 8 or below

This document describes how to replace traditional remote access service rsh by ssh on various platforms.

 

is a free version of the SSH suite of network connectivity tools that increasing numbers of people on the Internet are coming to rely on. telnet, rlogin, ftp, and

the traditional remote access services

The following tasks are discussed:

 

·         How to use ssh to replace telnet, rsh and rlogin.

·         How to use scp to replace rcp.

·         How to use sftp to replace ftp for file transfer.

·         How to access server by ssh on Windows.

·         How to transfer file by sftp on Windows.

 

To access a server from on *nix machine, you can use ssh directly.  The usage is:

 

ssh hostname

 

To access the server as special account, you can also use:

 

ssh user@hostname

 

or

 

ssh hostname -l user

 

For example:

 

[root@node1 tmp]# ssh allenzhang@node2

allenzhang@node2's password:

Last login: Tue May 23 01:05:08 2006 from node1

[allenzhang@node2 ~]$

 

[root@node1 tmp]# ssh node2 -l allenzhang

allenzhang@node2's password:

[allenzhang@node2 ~]$

 

 

The usage of scp is much like rcp, and it can make more perfect. The -p option and -r option play the same roles as rcp as scp.  You can set the ownership of remote server.

 

     -p      Preserves modification times, access times, and modes from the original file.

     -r      Recursively copy entire directories.

 

To use scp:

 

scp source_file hostname:destination folder/file_name

 

For example:

 

[root@node1 tmp]# scp ic_env.pbd allenzhang@node2:/home/allenzhang

allenzhang@node2's password:

ic_env.pbd                                                          100%    0     0.0KB/s   00:00

[root@node1 allenzhang]# ls -l ic_env.pbd

-rw-r--r--  1 allenzhang allenzhang 0 May 23 01:09 ic_env.pbd

    There is another useful option in scp to set the used bandwidth

     -l limit Limits the used bandwidth, specified in Kbit/s.

 

 

sftp is much like ftp.  Commands of ftp are supported in sftp. You need not to set transfer mode to binary or ACSII in sftp.  In sftp or scp all transfers are all in binary.

 

For example:

 

[root@node1 tmp]# sftp allenzhang@node2

Connecting to node2...

allenzhang@node2's password:

There are lots of free ssh client software on Windows platform. There are two recommendations: putty and SSH Tectia^TM Client.

 

putty is free ssh client, it is green software as well. You can download it to your PC and use it directly. You can save the server configuration in putty and you need not input the IP address of server everytime.  After double-clicking the putty executable icon, it should show as below.

 

 

Double click the saved record, unix_server in this case, then you will connect to server directly.

 

 

You can get download the pscp.exe and psftp.exe to enable scp and sftp functions on your PC. you can save your putty tools to a special folder then set it as part of PATH in your environment.  Then you can use them everywhere on your pc.

 

 

set PATH=C:\path\to\putty\directory;%PATH%
