Honesty admin

From ProgClub
Jump to: navigation, search

This page chronicles the administrative changes to honesty.progclub.net. If you make an administrative change you should document the change here. Changes are logged he in reverse chronological order with a time-stamp in the form YYYY-MM-DD hh:mm. You can use the time from whatever timezone you are in, or UTC if you're cool, but use 24 hour time. Don't worry if the changes you make have a time-stamp that is less than a time-stamp later in the page, put the latest changes at the top. Put a link to your wiki user account before the time-stamp so we know who's doing what. See the Administrative reference for other information.

Updating Kerberos integration with Apache2

This article was helpful.

Edited /etc/apache2/sites-available/default-ssl and updated the server-status stanza like this:

 <Location /server-status>
   SetHandler server-status
   Order allow,deny
   Allow from all
   AuthType Kerberos
   AuthName "ProgClub login"
   KrbServiceName HTTP/honesty.progclub.net@
   KrbAuthRealm PROGCLUB.ORG
   Krb5Keytab /etc/apache2/apache2.keytab
   Require valid-user
 </Location>

Note the new line that was inserted:

   KrbServiceName HTTP/honesty.progclub.net@

I ran klist on the keytab file, like this:

# klist -k /etc/apache2/apache2.keytab

Which reported:

Keytab name: WRFILE:apache2.keytab
KVNO Principal
---- --------------------------------------------------------------------------
  2 HTTP/honesty.progclub.net@PROGCLUB.ORG
  2 HTTP/honesty.progclub.net@PROGCLUB.ORG
  2 HTTP/honesty.progclub.net@PROGCLUB.ORG
  2 HTTP/honesty.progclub.net@PROGCLUB.ORG

But when I tried to use the full service name, i.e.:

HTTP/honesty.progclub.net@PROGCLUB.ORG

it didn't work. Similarly I tried specifying 'Any', but that didn't work either. Finally this service name worked:

HTTP/honesty.progclub.net@

Server is now authenticating via Kerberos! Happy Days! :)

Gitweb for Apache2

Following these instructions:

root@honesty:/# apt-get install gitweb
root@honesty:/# vim /home/apache/config/default-ssl 
Alias /gitweb /usr/share/gitweb
<Directory /usr/share/gitweb>
  Options +ExecCGI +FollowSymLinks +SymLinksIfOwnerMatch
  AllowOverride All
  order allow,deny
  Allow from all
  AddHandler cgi-script cgi
  DirectoryIndex index.cgi
</Directory>
root@honesty:/# vim /etc/gitweb.conf
# path to git projects (<project>.git)
#$projectroot = "/var/cache/git";
$projectroot = "/git";

# directory to use for temp files
$git_temp = "/tmp";

# target of the home link on top of all pages
#$home_link = $my_uri || "/";

# html text to include at home page
$home_text = "indextext.html";

# file with project list; by default, simply scan the projectroot dir.
$projects_list = $projectroot;

# stylesheet to use
$stylesheet = "/gitweb/gitweb.css";

# logo to use
$logo = "/gitweb/git-logo.png";

# the 'favicon'
$favicon = "/gitweb/git-favicon.png";
root@honesty:/# apache2ctl graceful

Git SSH and HTTPS support

root@honesty:/# apt-get install git-core

Follow these instructions to configure a git repository.

root@honesty:/# vim /home/apache/config/default-ssl 
SetEnv GIT_PROJECT_ROOT /git
SetEnv GIT_HTTP_EXPORT_ALL
SetEnv REMOTE_USER=$REDIRECT_REMOTE_USER
ScriptAlias /git/ /usr/lib/git-core/git-http-backend/
<LocationMatch "^/git/.*git-receive-pack.*">
  AuthType Basic
  AuthName "ProgClub git"
  AuthUserFile /home/apache/config/git.passwd
  Require valid-user
</LocationMatch>
<Directory /usr/lib/git-core/>
  AllowOverride None
  Options +ExecCGI -Includes
  Order allow,deny
  Allow from all
</Directory>

Fixing fstab NFS mount issue

There was a problem where fstab NFS mounts weren't working. To workaround the problem:

root@honesty:/# vim /etc/fstab

Comment out NFS mount:

#charity:/export/home /home     nfs4    rw,_netdev,auto 0 0
root@honesty:/# vim /etc/rc.local 

Add:

mount -t nfs charity:/export/home /home
service apache2 restart

Then reboot.

Configuring mod_status for Apache2

Edited the /home/apache/config/default-ssl file and added:

ExtendedStatus On

to the top of the file.

Added a /server-status location:

 <Location /server-status>
   SetHandler server-status
   Order allow,deny
   Allow from all
   AuthType Kerberos
   AuthName "ProgClub login"
   KrbAuthRealm PROGCLUB.ORG
   Krb5Keytab /etc/apache2/apache2.keytab
   Require valid-user
 </Location>

Configuring max connections for Apache2

Used:

root@honesty:/etc/apache2/mods-enabled# apache2 -V | grep MPM

To figure out which MPM setting was being used.

In the /etc/apache2/apache2.conf file dded:

ServerLimit         1000
MaxClients          1000

in the:

<IfModule mpm_prefork_module>

section.

Changed MaxKeepAliveRequests from 100 to 0:

#MaxKeepAliveRequests 100
MaxKeepAliveRequests 0

Restarted the server with:

# apache2ctl graceful

Then you need to patch syslog-summary to change the python2.5 env to python2:

#!/usr/bin/env python2

Installing and Configuring DNS for bkdns development

Install bind and dnsutils

tasaio@honesty:~$ sudo apt-get update && sudo apt-get install bind9
tasaio@honesty:~$ sudo apt-get install dnsutils

Generate a key

tasaio@honesty:~$ dnssec-keygen -a HMAC-MD5 -b 512 -n USER dev.progclub.biz.
tasaio@honesty:~$  cat Kdev.progclub.biz.+157+61713.key 
dev.progclub.biz. IN KEY 0 3 157 actualkeyremoved==

Add a zone to bind's config (let our key update it)

tasaio@honesty:~$ cat /etc/bind/named.conf.local
// ....
// Dynamic zone for testing the bkdns project
zone "progclub.biz" in {
        type master;
        file "progclub.biz.dns";
        allow-transfer { 172.19.1.28; };
        allow-update { key dev.progclub.biz.; };
        };

Set up the initial zone file

tasaio@honesty:~$ cat /var/cache/bind/dev.progclub.biz.dns 
;
; BIND data file for progclub.biz
;
$TTL    604800
@       IN      SOA     honesty.progclub.net. root.progclub.net. (

                              3         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      honesty.progclub.net.
@       IN      NS      hope.progclub.net.
@       IN      A       172.19.1.46

Add our key to bind's config

tasaio@honesty:/etc/bind$ cat named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the 
// structure of BIND configuration files in Debian, *BEFORE* you customize 
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local

include "/etc/bind/named.conf.options";
include "/etc/bind/named.conf.local";
include "/etc/bind/named.conf.default-zones";
include "/etc/bind/keys.conf";

tasaio@honesty:/etc/bind$ sudo cat keys.conf 
key dev.progclub.biz. {
        algorithm hmac-md5;
        secret "actualkeyremoved==";
        };

Restart Bind

tasaio@honesty:~$ sudo /etc/init.d/bind9 restart

This zone accepts dynamic updates. If you must update the zone file by hand, make sure you run

rndc freeze progclub.biz

before editing, and

rndc thaw progclub.biz

when finished.

Supporting /pcwiki URLs on Member Net

The way MediaWiki loads resources is to send a relative URL back to the server requesting the load of other resources. So basically we need to support /pcwiki URLs on Member Net as well as on the ProgClub web-site. To do that I added the following to /etc/apache2/sites-enabled/default-ssl:

RewriteEngine on
RewriteRule ^/pcwiki/(.*) https://www.progclub.org/pcwiki/$1 [NE]

Note that the [NE] was required at the end of the rewrite rule to avoid double-escaping.

Web-site goes HTTPS

Found this article which suggested the following in /etc/apache2/sites-enabled/www.progclub.net

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://www.progclub.net%{REQUEST_URI}

This has two benefits. One is that all web requests will be redirected to the secure site, and the second is that all HTTP requests will be redirected to the canonical domain.

Also had to run:

# a2enmod rewrite

# /etc/pam.d/common-password - password-related modules common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of modules that define the services to be
# used to change user passwords.  The default is pam_unix.

# Explanation of pam_unix options:
#
# The "sha512" option enables salted SHA512 passwords.  Without this option,
# the default is Unix crypt.  Prior releases used the option "md5".
#
# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
# login.defs.
#
# See the pam_unix manpage for other options.

# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules.  See
# pam-auth-update(8) for details.

# here are the per-package modules (the "Primary" block)
#password       requisite                       pam_krb5.so minimum_uid=1000
#password       [success=1 default=ignore]      pam_unix.so obscure use_authtok try_first_pass sha512
# here's the fallback if no module succeeds
#password       requisite                       pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
#password       required                        pam_permit.so
# and here are more per-package modules (the "Additional" block)
# end of pam-auth-update config
