- Unix-Systems |
| 4 |
o learn howto move/maintain /etc of servers at cvs !! |
| 5 |
Debian: |
| 6 |
x search if new packages available, do 'apt-get --dry-run upgrade'! |
| 7 |
x build small systool script 'apt-get_remote.pl' which do a cronly 'apt-get --dry-run upgrade' and send output via mail |
| 8 |
o review 'apt-get_remote.pl' |
| 9 |
o what's about parsing some response for comand like installing some marked packages |
| 10 |
|
| 11 |
|
| 12 |
- QoS (Quality of Services) |
| 13 |
o check it out ! |
| 14 |
|
| 15 |
- Apache/php: |
| 16 |
- apache aliases - redirect '/' to index.php (used for url catching/rewriting) |
| 17 |
|
| 18 |
- PHP: |
| 19 |
x search for php widget lib |
| 20 |
x APL (http://apl.sourceforge.net) |
| 21 |
- huge lib in pure C |
| 22 |
x phphtmllib (http://phphtmllib.newsblob.com) |
| 23 |
a mainly widget/render lib, written in php, complete OO-based |
| 24 |
and with nice DataList rendering (abstract source API) |
| 25 |
x integrated with flib |
| 26 |
x wrote some classes to browse data-objects via class DataList (new classes flibRPCDataSource, ObjectList, TsBackend) |
| 27 |
o rename flibRPCDataSource (maybe rework to get more abstract) |
| 28 |
o review ObjectList amd move it to phphhtmllib |
| 29 |
x semi-integraded with class FormBuilder from binarycloud via interface class FormElementsInterface |
| 30 |
x new class DataItem, which render one data object for viewing/editing |
| 31 |
x integrated new FormProcessing classes from phphtmllib (released one day after interface to binaryclouds Formbuilder was written ;) |
| 32 |
x refactored DataItem to use now phphtmllib form processing instead of interface to binarycload |
| 33 |
o review code and move to phphtmllib |
| 34 |
o XOOPS (http://xoops.org) |
| 35 |
XOOPS is a dynamic OO (Object Oriented) based open source portal script written in PHP. |
| 36 |
It is the ideal tool for developing small to large dynamic community websites, intra company portals, |
| 37 |
corporate portals, weblogs and much more. |
| 38 |
o binarycloud (http://binarycloud.com) |
| 39 |
binarycloud is an enterprise class web application platform. binarycloud shares many of the capabilities of products |
| 40 |
like Oracle 9i AS (Application Server) and IBM's WebSphere: |
| 41 |
Proper definition of a framework: "A framework supplies the infrastructure and mechanisms that execute a policy for |
| 42 |
interaction between abstract components with open implementations" |
| 43 |
- benefits: |
| 44 |
x much code done yet! |
| 45 |
- drawbacks: |
| 46 |
o not-really 100% clean code |
| 47 |
o complex app which gives you only limited possibilities to use only some classes, so not very modular |
| 48 |
|
| 49 |
|
| 50 |
- OpenLDAP: |
| 51 |
- Contacts: |
| 52 |
o Evolution: modify/create schema (map Attribute) so the field 'Note' and others can be used |
| 53 |
|
| 54 |
- PAM + SASL |
| 55 |
o seems pam will only works(will only be activated) if plain passwords are used |
| 56 |
o read more about PAM special in co-operate with SASL !! |
| 57 |
|
| 58 |
- Kerberos V |
| 59 |
x use GQ LdapBrowser with SASL to authenticate against ldap |
| 60 |
- this requires a 'kinit <username>' at the shell to get the kerberos ticket |
| 61 |
- ldap will check your ticket pricipial against its acl's ! |
| 62 |
o 'libpam-ldap' from Turbo is bad, don't use it !! (remember at 'apt-get upgrade' !!) |
| 63 |
o write this down in some (existing e.g. sendmail?) howto |
| 64 |
|
| 65 |
- Sendmail |
| 66 |
o research some about sendmail-cluster, 2 mx records, howto to set up second mx/cluster? |
| 67 |
x backup mx: |
| 68 |
- set up second mx at dns |
| 69 |
- add at backup mx place some like this at /etx/mail/mailtertable: |
| 70 |
domain.com esmtp:[123.123.123.123] |
| 71 |
where the ip points to the system the real user accounts |
| 72 |
and add every domain to /etc/mail/relay-domains: |
| 73 |
domain.com |
| 74 |
o whats about these *open* relaying rules(security ?!?) |
| 75 |
x simple load balancing: |
| 76 |
- set up two(or more) mx records with same priority at dns |
| 77 |
- add at every mx place some like this at /etx/mail/mailtertable: |
| 78 |
domain.com esmtp:[123.123.123.123] |
| 79 |
where the ip points to the system the real user accounts are |
| 80 |
note: this will do load balancing between eg 2 mail server, but if one fails, |
| 81 |
there is only a 50% chance that sent messages would arrive |
| 82 |
o change '/etc/init.d/amavisd' to '/etc/init.d/amavis-milter' in howto |
| 83 |
o migrationtools: |
| 84 |
o patch migrationtools for sendmail aliases support (/usr/share/migrationtools/migrate_aliases.pl) |
| 85 |
o create, or search web for, migrationtool for sendmail virtusertable (/usr/share/migrationtools/migrate_virtuser.pl) |
| 86 |
o review patched kerberosV support at /usr/share/migrationtools/migrate_user.pl? |
| 87 |
|
| 88 |
|
| 89 |
- MySQL: |
| 90 |
o move this to mysql-common-tasks howto |
| 91 |
- Create Database |
| 92 |
:# mysqladmin create <database> |
| 93 |
- Set Privileges on databases(creates user too, if not exists...): |
| 94 |
mysql>grant all on {database}.* to {user} identified by "{pass}"; |
| 95 |
mysql>grant all on {database}.* to {user}@{domain} identified by "{pass}"; |
| 96 |
|
| 97 |
|
| 98 |
- Document saving: |
| 99 |
o remember *.doc is a non-standard, bloated Mircosoft format, use HTML instead !! |
| 100 |
see http://www.fsf.org/philosophy/no-word-attachments.html |
| 101 |
|
| 102 |
- my documents: |
| 103 |
o convert all howto's to SDF format ( look at 'nfo/doc/computing/sysadmin/linux/example_sdf_howto.sdf' ) |
| 104 |
o learn more about Lyx/LaTex |
| 105 |
o convert all howto's to LaTex format ( look at 'nfo/doc/computing/sysadmin/linux/example_latex_howto.lyx' ) |
| 106 |
|
| 107 |
|
| 108 |
- news.netfrag.org: |
| 109 |
o create remote functions to implement e.g.: |
| 110 |
o a mozilla button for creating new newsgroups |
| 111 |
|
| 112 |
|
| 113 |
|
| 114 |
|
| 115 |
future: |
| 116 |
o build 'black box' to trace for 'spys' at a isdn/internet connection ;) |
| 117 |
