install ssh openbsd

[darken]

Hello

I am novice under openbsd, how we install and configure shh

Thank you

[Nightweaver]

SSH server is already there. You just have to enable it in /etc/rc.conf to be started at boot. Configuration is done in /etc/ssh/sshd_config. For more details check: http://www.openssh.org/faq.html

Hello

install shh?

Thank

[Nightweaver]

Why would you install SSH when it's already there? Here are instructions for comiling and installing OpenSSH: http://www.openssh.org/openbsd.html

[jggimi]

The client program is ssh(1). The server program is sshd(8).

You may use the client program without any prior configuration. e.g.:

$ ssh user@server

The server program needs to be configured to start on boot. The installation script asks you if you want sshd started automatically. If you did not reply "y" then you will have to start it manually, or configure it yourself in /etc/rc.conf or /etc/rc.conf.local.

Hello

The command cd /usr/src/usr.bin

No such file or directory

[jggimi]

You do NOT need to compile or install OpenSSH. OpenSSH is already installed in OpenBSD. It comes with OpenBSD. It is included in OpenBSD. All you need to do is USE it.

To use the OpenSSH client, issue the "ssh" command, as shown above.

To manually start the OpenSSH server, from a root shell, issue:

# /usr/sbin/sshd

To have the OpenSSH server start automatically when OpenBSD is booted, from a root shell, add

sshd_flags=""

to /etc/rc.conf.local. If you do not know how to use an editor, you can type:

# echo sshd_flags=\"\" >> /etc/rc.conf.local

That's it. You do NOT need to download source, compile, or install OpenSSH. It is already in your OS.

If you wish to configure server or client settings, you must do that by editing /etc/ssh/sshd_config and /etc/ssh/ssh_config.

In addition to jggimi's comments, SSH could have been configured during installation. See Section 4.5.7 of the FAQ for more information:

By default, user accounts can use ssh(1) to connect to remote systems.

Allowing root access on a remote system can be configured on remote systems by setting PermitRootLogin in /etc/ssh_config. More information can be found in the ssh_config(5) manpage.

Root access is needed to start the server, sshd. Client use does not require root access.

How to create a new user

A discussion of the commands you need are in the afterboot(8) man page.

The e-mail awaiting root in the default install (the file /var/mail/root) should be helpful, too.

That's the client configuration file. I think you meant sshd_config(5) instead.

adduser(8). Creating user accounts is independent of SSH issues.

Correct. Thanks.

A discussion of adduser, vipw, and su are in the "Add new users" section of the afterboot man page.

Please, read it. A lot of people put in a great deal of effort to write the documentation, and it is far easier to read the information than it is to type up your questions.

Hello

When I connect Authentication failed,

When I type the command Adduser

Reading /etc/shells
Check /etc/master.passwd
Password file busy

Authentication can fail for many reasons. Here are several:

• You are using an invalid userid -- right now, your only valid userid is "root"
• The root password is blank
• root login is not permitted -- the default is to allow it
• Password Authentication is disabled -- the default is to allow it

Where are you connecting from? What userid are you using?

...Password file busy

Are you trying to run adduser from multiple consoles? Are you trying to use vipw at the same time as adduser?

Provide more information.

[darken]

the root command adduser
