97: <LI>Unshadow passwords
98: <UL>
99: <PRE>You can do this by these 5 steps:
100: 1. enter the system command, as "root", pwunconv
101: 2. enter the system command, as "root", grpunconv
102: 3. Set the following to be the /etc/pam.d/login file on your system
103: #%PAM-1.0
104: auth required /lib/security/pam_securetty.so
105: auth required /lib/security/pam_pwdb.so shadow nullok
106: auth required /lib/security/pam_nologin.so
107: account required /lib/security/pam_pwdb.so
108: password required /lib/security/pam_cracklib.so
109: password required /lib/security/pam_pwdb.so nullok use_authtok
110: session required /lib/security/pam_pwdb.so
111: session optional /lib/security/pam_console.so
112: 4. Set the following to be the /etc/pam.d/passwd file on your system
113: #%PAM-1.0
114: auth required /lib/security/pam_pwdb.so shadow nullok
115: account required /lib/security/pam_pwdb.so
116: password required /lib/security/pam_cracklib.so retry=3
117: password required /lib/security/pam_pwdb.so use_authtok nullok
118: 5. Set/reset passwords. As "root" use 'passwd', and 'passwd www'
119: to change the important passwords. This creates crypt-processible
120: passwords in /etc/passwd.
121: </PRE>
122: </UL>
123: <LI>Run, as root, <TT>ln -s /etc/mime.types /etc/httpd/conf/mime.types</TT>
124: <LI>Run, as root, <TT>/etc/rc.d/init.d/httpd start</TT>.
125: <LI>Run, as root, <TT>/etc/rc.d/init.d/loncontrol start</TT>.
126: <LI>After 10 minutes, you should be able to check the file <TT>/home/httpd/html/lon-status/index.html</TT>
127: to see if your machine has been successfully set up.

132: <P>
133: In the future, LON-CAPA Installation will be distributed on a CD complete with a
134: customized interface. Many elements for doing this have been coded, and are in place, but
135: it awaits completion.
