Install OpenSSH 5.2 on CentOS 5

Filed under: Centos 5 — Tags: — admin @ 2:56 pm

Centos 5 yum doesn’t seem to support latest OpenSSH 5.2 which support many features. (it’s like 4.2)

Make sure you have development tools:

# yum install gcc
# yum install openssl-devel
# yum install pam-devel
# yum install rpm-build

And then download openssh 5.2p1

# wget ftp://mirror.planetunix.net/pub/OpenBSD/OpenSSH/portable/openssh-5.2p1.tar.gz

Now, we’re going to build RPM based on tar.gz file:

# tar xvfz openssh-5.2p1.tar.gz
# cp ./openssh-5.2p1/contrib/redhat/openssh.spec /usr/src/redhat/SPECS/
# cp  ./openssh-5.2p1.tar.gz /usr/src/redhat/SOURCES/
# cd /usr/src/redhat/SPECS/
# perl -i.bak -pe 's/^(%define no_(gnome|x11)_askpass)\s+0$/$1 1/' openssh.spec
# rpmbuild -bb openssh.spec
# cd /usr/src/redhat/RPMS/`uname -i`
# ls -l

-rw-r--r-- 1 root root 271758 Jun 30 12:39 openssh-5.2p1-1.i386.rpm
-rw-r--r-- 1 root root 429852 Jun 30 12:39 openssh-clients-5.2p1-1.i386.rpm
-rw-r--r-- 1 root root 268302 Jun 30 12:39 openssh-server-5.2p1-1.i386.rpm

# rpm -Uvh openssh*rpm
Preparing... ################################
1: openssh ####
2: openssh-clients ####
3: openssh-server ####
# service sshd restart

Then, RPM version of SSH installs.  After restarting, it may say initlog is obsolete, but, you can ignore as that option is deprecated.
