Recompiling SSHD in Centos. Using the same bind directory
I have shown little sample here with openssh 6.0p1 on centos 5.6 (tested).
Problems faced and solution :
root@ashishnepal ssh]# service sshd restart
Stopping sshd: [ OK ]
Starting sshd: /etc/ssh/sshd_config line 22: Unsupported option GSSAPIAuthentication
/etc/ssh/sshd_config line 23: Unsupported option GSSAPICleanupCredentials
/etc/ssh/sshd_config line 25: Unsupported option UsePAM
[ OK ]
SCRIPT
#!/bin/bash
yum -y install libgssapi pam-devel
SOURCEDWN="http://www.mirrorservice.org/sites/ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-6.0p1.tar.gz"
SOURCELOCATION=/usr/local/src
CONFIGLOCATION=/etc/ssh/
FILE=openssh-6.0p1.tar.gz
cd $SOURCELOCATION && wget $SOURCEDWN && tar -zxvf $SOURCELOCATION/$FILE ;
echo `mkdir $CONFIGLOCATION/old ;
mv $CONFIGLOCATION/ssh* $CONFIGLOCATION/moduli $CONFIGLOCATION/old/serv` ;
cd /usr/local/src/openssh-6.0p1 &&
./configure --sysconfdir=/etc/ssh --bindir=/usr/bin/ --sbindir=/usr/sbin --with-pam --with-kerberos5 && make && make install;
cd /etc/ssh/;
mv /etc/ssh/sshd_config /etc/ssh/sshd_config.bak && cat /etc/ssh/old/sshd_config | grep -v "^#" >> /etc/ssh/sshd_config;
echo `ssh -V`;
service sshd restart
Problem: However, script includes the below given problem if you skim through.
./configure --sysconfdir=/etc/ssh --bindir=/usr/bin/ --sbindir=/usr/sbin
make
make install
[root@ashishnepal ssh]# service sshd restart
Stopping sshd: [ OK ]
Starting sshd: /etc/ssh/sshd_config line 22: Unsupported option GSSAPIAuthentication
/etc/ssh/sshd_config line 23: Unsupported option GSSAPICleanupCredentials
/etc/ssh/sshd_config line 25: Unsupported option UsePAM
[ OK ]
if you need UsePAM yes and GSSAPIAuthentication Yes you should also config with pam and kerberos5 as given above.
inorder to make it usable you might need “yum install libgssapi pam-devel”
Solution: After installing libgssapi and pam-devel
./configure --sysconfdir=/etc/ssh --bindir=/usr/bin/ --sbindir=/usr/sbin --with-pam --with-kerberos5
