OpenSSH for OpenBSD

Since OpenSSH is developed by the OpenBSD group, OpenSSH is included in the base operating system, starting at OpenBSD release 2.6. So there's nothing to install or add to your system. However, due to newer features or other patches, you may wish to upgrade.

The following versions of OpenSSH are available for putting on your OpenBSD machines:

OpenSSH 2.3.0: Nov 6, 2000
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openssh-2.3.0.tgz
OpenSSH 2.3.0 is included in OpenBSD 2.8.
To extract and install it on your OpenBSD 2.7 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-2.3.0.tgz
# cd ssh
comment 'CFLAGS+=-DHAVE_LOGIN_CAP' in sshd/Makefile, using a # character.
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
Note: This above source fails to build on earlier OpenBSD, because IPV6 support in libc was incomplete.
OpenSSH 2.2.0: Aug 31, 2000
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openssh-2.2.0.tgz
To extract and install it on your OpenBSD 2.7 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-2.2.0.tgz
# cd ssh
comment 'CFLAGS+=-DHAVE_LOGIN_CAP' in sshd/Makefile, using a # character.
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
Note: This above source fails to build on earlier OpenBSD, because IPV6 support in libc was incomplete.
If you are installing on OpenBSD 2.6, you also need the following patch:
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openbsd26_2.2.0.patch.
To extract and install it on your OpenBSD 2.6 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-2.2.0.tgz
# patch -p0 < openbsd26_2.2.0.patch
# cd ssh
uncomment 'CFLAGS+=-DHAVE_LOGIN_CAP' in sshd/Makefile
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
Note that using OpenSSH 2.2.0 on OpenBSD 2.6 will require one of the ssl27.tgz or sslUSA27.tgz packages instead of the 2.6 varients. This updates your ssl libraries to a newer version of OpenSSL, which contains new calls which OpenSSH requires. Also, if you want to use SSH2, and do not already have a DSA key, you need to create one using
```
# /usr/bin/ssh-keygen -d -f /etc/ssh_host_dsa_key -N ''
```
OpenSSH 2.1.1: June 8, 2000
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openssh-2.1.1.tgz
To extract and install it on your OpenBSD 2.7 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-2.1.1.tgz
# cd ssh
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
Note: This above source fails to build on earlier OpenBSD, because IPV6 support in libc was incomplete.
If you are installing on OpenBSD 2.6, you also need the following patch:
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openbsd26_2.1.1.patch.
To extract and install it on your OpenBSD 2.6 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-2.1.1.tgz
# patch -p0 < openbsd26_2.1.1.patch
# cd ssh
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
Note that using OpenSSH 2.1.1 on OpenBSD 2.6 will require one of the ssl27.tgz or sslUSA27.tgz packages instead of the 2.6 varients. This updates your ssl libraries to a newer version of OpenSSL, which contains new calls which OpenSSH requires. Also, if you want to use SSH2, and do not already have a DSA key, you need to create one using
```
# /usr/bin/ssh-keygen -d -f /etc/ssh_host_dsa_key -N ''
```
OpenSSH 2.1.0: May 8, 2000
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openssh-2.1.0.tgz
To extract and install it on your OpenBSD 2.7 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-2.1.0.tgz
# cd ssh
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
Note: This above source fails to build on earlier OpenBSD, because IPV6 support in libc was incomplete.
If you are installing on OpenBSD 2.6, you also need the following patch:
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openbsd26_2.1.0.patch.
To extract and install it on your OpenBSD 2.6 system:

OpenSSH 1.2.3: released March 6, 2000
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openssh-1.2.3.tgz
To extract and install it on your OpenBSD 2.7 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-1.2.3.tgz
# cd ssh

# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```

If you are installing on OpenBSD 2.6, you also need the following patch:
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/openbsd26_1.2.3.patch.
To extract and install it on your OpenBSD 2.6 system:
```
# cd /usr/src/usr.bin
# tar xvfz .../openssh-1.2.3.tgz
# cd ssh
# patch -p1 < openbsd26_1.2.3.patch
# make obj
# make cleandir
# make depend
# make
# make install
# cp ssh_config sshd_config /etc
```
