3# runnable as it stands.

11# Old versions of this install document advised setting
12# NSS_NONLOCAL_IGNORE=1 anytime you're setting up anything, e.g. using
13# yum, warning that useradd will query LDAP in a stupid way that makes
14# it hang forever.  As of Fedora 13, this does not seem to be a problem,
15# so it's been removed from the instructions.  If an install is hanging,
16# though, try adding NSS_NONLOCAL_IGNORE.
17
18# This is actually just "pick an active scripts server".  It can't be
19# scripts.mit.edu because our networking config points that domain
20# at localhost, and if our server is not setup at that point things
21# will break.

63#     the keytab.  Do not use 'k5srvutil change' on the combined keytab
64#     or you'll break the other servers. (real servers only).  Be
65#     careful about writing out the keytab: if you write it to an
66#     existing file the keys will just get appended.  The correct
67#     credential list should look like:
68#       ktutil:  l

73#          3    2      host/scripts.mit.edu@ATHENA.MIT.EDU
74#   o Replace the ssh host keys with the ones common to all scripts servers (real servers only)
75    ls -l /etc/ssh/*key*
76#     You can do that with:
77scp root@$source_server:/etc/ssh/*key* .

87# NOTE: You will have just lost DNS resolution and the ability
88# to do password SSH in.  If you managed to botch this step without
89# having named setup, you can do a quick fix by frobbing /etc/resolv.conf
90# with a non 127.0.0.1 address for the DNS server.  Be sure to revert it once
91# you have named.
92
93# NOTE: You can get password SSH back by editing /etc/ssh/sshd_config (allow
94# password auth) and /etc/pam.d/sshd (comment out the first three auth
95# lines).  However, you should have the Kerberos credentials in place
96# so as soon as you install the full set of Scripts packages, you'll get
97# Kerberized logins.
98
99# Make sure network is working.  If this is a new server name, you'll
100# need to add it to /etc/hosts and
