Install SSH on RedHat

1. Download openssl-0.9.8e.tar.gzand openssh-4.6p1.tar.gz. The former is the SSL protocol, and the latter is the shell.

2. Install OpenSSL 2.2

 

# Cd/usr/local/src

# Tar zxvf openssl-0.9.8e.tar.gz

# Cd openssl-0.9.8e

#./Config shared zlib

# Make

# Make Test

# Make install

MV/usr/bin/OpenSSL. Off

MV/usr/include/OpenSSL. Off

Ln-S/usr/local/SSL/bin/OpenSSL/usr/bin/OpenSSL

Ln-S/usr/local/SSL/include/OpenSSL/usr/include/OpenSSL

 

2.3 configure the library file search path

 

# Echo "/usr/local/SSL/lib">/etc/lD. So. conf

# Ldconfig-V

 

2.4 check the OpenSSL version to verify whether the installation is correct.

 

# OpenSSL version-

Openssldir: "/usr/local/SSL"

 

3. download and install the latest OpenSSH

 

3.1 download the software package to the/usr/local/src directory.

 

Ftp://openbsd.nsysu.edu.tw/BSD/OpenBSD/OpenSSH/portable/openssh-4.6p1.tar.gz

 

3.2 Installation

 

# Cd/usr/local/src

# Tar zxvf openssh-4.6p1.tar.gz

# Cd openssh-4.6p1

#. /Configure -- prefix =/usr -- sysconfdir =/etc/ssh -- With-pam -- With-zlib -- With-SSL-Dir =/usr/local/SSL -- with-md5-passwords -- Mandir = /usr/share/man

# Make

# Make install

 

3.3 check the OpenSSH version number and verify the installation result

 

# Ssh-V

Openssh_4.6p1, OpenSSL 0.9.8e 11 Apr 2007

Usage: SSH [-1246 aacfgkmnnqsttvvxxy] [-B bind_address] [-C cipher_spec]

[-D [bind_address:] Port] [-e escape_char] [-F configfile]

[-I identity_file] [-L [bind_address:] Port: Host: hostport]

4. Start and verify the Service Activation status

 

4.1 debug and start sshd properly.

 

#/Usr/sbin/sshd-d

Debug1: sshd version openssh_4.6p1

Debug1: Private host key: #0 Type 0 rsa1

Debug1: Read PEM Private Key done: Type RSA

Debug1: Private host key: #1 Type 1 RSA

Debug1: Read PEM Private Key done: Type DSA

Debug1: Private host key: #2 type 2 DSA

Debug1: rexec_argv [0] = '/usr/sbin/sshd'

Debug1: rexec_argv [1] = '-d'

Socket: address family not supported by Protocol

Debug1: bind to port 22 on 0.0.0.0.

Server listening on 0.0.0.0 port 22.

Generating 768 bit RSA key.

RSA key generation complete.

 

4.2 start the service

 

#/Usr/sbin/sshd

 

4.3 check whether there are 22 listening ports

 

# Netstat-tnlp | grep: 22

TCP 0 0 0.0.0.0: 22 0.0.0.0: * Listen 21018/sshd

 

4.4 try to log on from the local machine through SSH

 

# SSH root @ localhost

The authenticity of host 'localhost (127.0.0.1) 'can't be established.

RSA key fingerprint is 03: EB: 80: Fe: 07: D9: 9d: 00: 1c: 15: 37: 93: D1: D3: 8e: 6d.

Are you sure you want to continue connecting (Yes/No )? Yes

Warning: Permanently added 'localhost' (RSA) to the list of known hosts.

Root @ localhost's password:

Last login: Wed Apr 11 11:29:04 2007 from localhost. localdomain
