====== Slackware Application ======

Running applications (@software) on Slackware... most are applicable to all distributions.

===== 'Hidden' Application =====

There are a couple (a few?)of applications that I thought  have great features but relatively unknown (I only knew about them after looking for specific solution). Here they are:  

  * xfig - nice app to create figures for use with latex
  * xpaint - can do screen capture (''xpaint -snapshot'')

===== Apache (web server) Setup =====

Modify httpd config file:
  * change document root to a folder my main user have full access
    * also create a link to it from my user account
  * allow php to be indexed => add to directory index in dir_module
  * enable php (towards the end of the file) => include mod_php.conf
  * enable mod_rewrite (API server?) => LoadModule ... mod_rewrite.so
  * optional: set serveradmin email and servername
  * optional: to only serve locally, set listen localhost:80 ???

More modifications for https:
  * enable loadmodule mod_ssl.so
  * enable loadmodule mod_socache_shmcb.so

  * generate private key:
    * <code>openssl genrsa -out privkey.pem 2048</code>
    * rsa private key with 2048-bit long modulus written to file
  * generate cert:
    * <code>openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095</code>

  * include httpd-ssl.conf
    * modify httpd-ssl.conf accordingly...

===== mariadb/mysql Setup =====

  * run <code>mysql_install_db</code>
  * make sure permision given to user //mysql// <code>chown -R mysql:mysql /var/lib/mysql</code>
  * start daemon ''rc.mysqld''
  * run <code>/usr/bin/mysql_secure_installation</code>

  * create specific database for specific app <code>create database app_db;</code>
  * create specific user for specific app and grant all access <code>grant all privileges on app_db.* to 'user_app'@'localhost' identified by 'pass_app';</code>
  * just formality, run <code>flush privileges;</code>
  * to additionally create specific user for specific app <code>create user 'user_app'@'localhost' identified by 'pass_app';</code>

  * recover root password: 
  * stop daemon ''rc.mysqld''
  * run <code>
# mysqld_safe --skip-grant-tables &
# mysql -u root
$ mysql -uroot -p
mysql> use mysql;
mysql> update user set password=PASSWORD('<newpass>') where User='root';
mysql> flush privileges;
mysql> exit
</code>

Backup a DB:<code>mysqldump -p -u user userdb > userapp-$(date +%Y%m%d%H%M%S).sql</code>

===== TeXLive Install/Setup =====

The default tetex is usable, but it is no longer maintained and some new packages are not available.

===== rsync server =====

  * create ''rsyncd.conf'' in etc <file text rsync.conf>
max connections = 2
log file = /var/log/rsync.log
timeout = 300

[share]
comment = Shared Stuff
path = /home/share
read only = yes
list = yes 
hosts allow = 192.168.3.0/24
uid = nobody
gid = nobody
#auth users = pub
#secrets file = etc/rsyncd.secrets
</file>
    * modify subnet mask address for host allow accordingly
  * in ''inetd.conf'' (etc), insert <code>rsync	stream	tcp	nowait	root	/usr/bin/rsync	rsync --daemon</code>
  * in ''services'' (etc), insert <code>rsync	873/tcp</code>
  * create ''rsyncd.secrets'' in etc <file text rsyncd.secrets>
pub:pub
</file>
  * start rsync daemon<code>/usr/bin/rsync --daemon --config=etc/rsyncd.conf</code>

===== Steam on Slack64 (in chroot32) =====

on an x86_64 machine,
  * install libtxc_dxtn package from slackbuilds.org (64-bit)
  * use 'slackroot' to create 32-bit chroot environment (chroot32)
    * target for desktop
  * ssh into localhost to enter chroot32 as normal user
    * remember to run 'preproot' (as root) prior to that
    * ... and 'preproot --release' when done
  * install packages
    * install alien_bob's steamclient package
    * install libtxc_dxtn package from slackbuilds.org (32-bit)
  * run 'linux32' to create an official 32-bit environment
  * run 'steam -tcp'
