Unix Study-AIX installation and configuration of SSH

System environment: AIX 6100-09 (SP3)

The default AIX system does not install ssh, which requires another custom installation. Ssh consists of two software packages (openssl and openssh), which can be unzipped and installed through smit.

First, install ssh

[root@aix209 ssh] # ls

OpenSSH_5.8.0.6102.tar.Z openssl-0.9.8.1802.tar.Z

Ssh.txt

[root@aix209 ssh] # uncompress OpenSSH_5.8.0.6102.tar.

1) decompression

[root@aix209 ssh] # uncompress openssl-0.9.8.1802.tar.Z

[root@aix209 ssh] # ls

OpenSSH_5.8.0.6102.tar

Openssl-0.9.8.1802.tar

Ssh.txt

2) install via smit

[root@aix209 ssh] # smit installp

3) View ssh service

[root@aix209 ssh] # lumped cards c-a | grep ssh

Sshd ssh 6029368 active

2. Configure to establish a trust relationship between hosts through ssh (Cluster)

One node:

1) establish the key

[grid@aix209 grid] $ssh-keygen-t rsa

Generating public/private rsa key pair.Enter file in which to save the key (/ home/grid/.ssh/id_rsa): Created directory'/ home/grid/.ssh'.Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in / home/grid/.ssh/id_rsa.Your public key has been saved in / home/grid/.ssh/id_rsa.pub.The key fingerprint is:46:8c:ac:aa:82:62:b1:5e:e2:ba: Ed:d5:02:5e:f5:62 grid@aix209The key's randomart p_w_picpath is:+-- [RSA 2048]-+ |. O | | + o | | o | |. O E S | | o + o | |.. = .o. | | = = o.. | | Xfolo | +-+ |

[grid@aix209 grid] $ssh-keygen-t dsa

Generating public/private dsa key pair.Enter file in which to save the key (/ home/grid/.ssh/id_dsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in / home/grid/.ssh/id_dsa.Your public key has been saved in / home/grid/.ssh/id_dsa.pub.The key fingerprint is:4a:6d:60:35:ee:1c:fe:7d:62:54:f6:31:5c:7b:4a:54 grid @ aix209The key's randomart p_w_picpath is:+-- [DSA 1024]-+ | o.. E | | o. .. O | | o + =. | |. *. + o+ | |. S. . . | |. O. O | |. . +. | |. O | +-+

2) configure key pairs

[grid@aix209 ~] $cd .ssh

[grid@aix209 .ssh] $ls

Id_dsa id_dsa.pub id_rsa id_rsa.pub

[grid@aix209 .ssh] $cd..

[grid@aix209 ~] $cat .ssh / id_rsa.pub > > .ssh/authorized_keys

[grid@aix209 ~] $cat .ssh / id_dsa.pub > > .ssh/authorized_keys

[grid@aix209 ~] $ssh aix210 cat .ssh / id_rsa.pub > > .ssh/authorized_keys

The authenticity of host 'aix210 (192.168.8.210)' can't be established.

RSA key fingerprint is 65:25:9b:46:05:a4:84:73:76:d2:ba:d2:c8:a2:91:0e.

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

Warning: Permanently added 'aix210192.168.8.210' (RSA) to the list of known hosts.

Grid@aix210's password:

[grid@aix209 ~] $ssh aix210 cat .ssh / id_dsa.pub > > .ssh/authorized_keys

Grid@aix210's password:

3) Test the trust relationship

[grid@aix209 ~] $ssh aix210-priv date

The authenticity of host 'aix210-priv (10.10.10.210)' can't be established.

RSA key fingerprint is 65:25:9b:46:05:a4:84:73:76:d2:ba:d2:c8:a2:91:0e.

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

Mon Jan 5 22:24:27 CST 1970

[grid@aix209 ~] $ssh aix209-priv date

The authenticity of host 'aix209-priv (10.10.10.209)' can't be established.

RSA key fingerprint is 8f:54:98:0e:1b:c1:81:10:36:88:62:e2:20:61:16:91.

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

[grid@aix209 ~] $ssh aix209 date

The authenticity of host 'aix209 (192.168.8.209)' can't be setablished.
