Tämä ohje on tarkoitettu Ubuntu 8.04.1-versiolla. Ohje perustuu asennukseen, joka tehtiin Valamossa LTSP5-työpajassa tammikuussa 2009. Asennuksen teki Mikael Lammentausta.

----
@ Mikael: teen vielä tämän päivän (22.1) näitä siirroksia asetustiedostoista, lisäksi käytän kummankin koneen bash_history-tiedostoja, joista yritän nähdä mitä kulloinkin teit, sieltä saan myös komentorivikäskyjä, joita käytit. Laita huomenna (23.1) omat kommenttisi ja korjauksesi tänne sekaan. Kun saamme tämän jotenkin kasaan, niin yritän tämän pohjalta tehdä vielä puhtaan openLDAP-asennusken LTSP5:n jatkoksi. Kiitos, Asmo.
----

 /!\ Tämä ohje ei ole leikkaa-liimaa-tyyppinen, vaan pikemminkin mahdollisimman tarkka kuvaus yhdestä toimivasta LTSP5-openLDAP-palvelinyhdistelmästä.

 {i} Toivomme, että lähtien liikkeelle tästä peruskuvauksesta saamme luoduksi monipuolisen ohjeen koskien openLDAP-käyttöä LTSP5-ympäristössä.

Tässä ohjeessa edellytetään, että käytössä on kaksi palvelinkonetta, jossa ensimmäiseen on ensin asennettu täysin toimiva LTSP5-ympäristö. Toiseen koneeseen riittää pelkkä Ubuntu 8.04.1-asennus. Näissä kahdessa palvelinkoneessa on yksi verkkokortti kummassakin. Perusasennuksen jälkeen tässä ohjeessa on käytössä seuraavanlaista lähiverkkoa. LTSP5-perusasennuksesta, tosin kahdella verkkokortilla, löytyy oma ohjeensa: http://wiki.ubuntu-fi.org/LTSP5_Perusasennus.

ADSL-modeemi jakaa LAN-reitittimelle/kytkimelle ip-osoitteen (192.168.0.100). Lähiverkkoon päin LAN-reititin/kytkin näkyy ip-osoitteessa '''192.168.1.1'''. Tämä LAN-reititin/kytkin tarjoaa myös nimipalvelut.

Palvelin, jossa on LTSP5-ympäristö, on '''192.168.1.101'''.

Palvelin, jossa on openLDAP, on '''192.168.1.102'''.

Pääte, jolle on annettu kiinteä ip-osoite MAC-osoitteen perusteella, on '''192.168.1.200'''. Pääte myös kirjautuu automaattisesti.

== Lähiverkon perusasetukset ==

Tässä ohjeessa on käytetty seuraavanlaisia asetustiedostoja.

LTSP5 - openLDAP

Tämä ohje on tarkoitettu Ubuntu 8.04.1-versiolla. Ohje perustuu asennukseen, joka tehtiin Valamossa LTSP5-työpajassa tammikuussa 2009. Asennuksen teki Mikael Lammentausta.

@ Mikael: teen vielä tämän päivän (22.1) näitä siirroksia asetustiedostoista, lisäksi käytän kummankin koneen bash_history-tiedostoja, joista yritän nähdä mitä kulloinkin teit, sieltä saan myös komentorivikäskyjä, joita käytit. Laita huomenna (23.1) omat kommenttisi ja korjauksesi tänne sekaan. Kun saamme tämän jotenkin kasaan, niin yritän tämän pohjalta tehdä vielä puhtaan openLDAP-asennusken LTSP5:n jatkoksi. Kiitos, Asmo.

  • Tämä ohje ei ole leikkaa-liimaa-tyyppinen, vaan pikemminkin mahdollisimman tarkka kuvaus yhdestä toimivasta LTSP5-openLDAP-palvelinyhdistelmästä.

    Toivomme, että lähtien liikkeelle tästä peruskuvauksesta saamme luoduksi monipuolisen ohjeen koskien openLDAP-käyttöä LTSP5-ympäristössä.

Tässä ohjeessa edellytetään, että käytössä on kaksi palvelinkonetta, jossa ensimmäiseen on ensin asennettu täysin toimiva LTSP5-ympäristö. Toiseen koneeseen riittää pelkkä Ubuntu 8.04.1-asennus. Näissä kahdessa palvelinkoneessa on yksi verkkokortti kummassakin. Perusasennuksen jälkeen tässä ohjeessa on käytössä seuraavanlaista lähiverkkoa. LTSP5-perusasennuksesta, tosin kahdella verkkokortilla, löytyy oma ohjeensa: http://wiki.ubuntu-fi.org/LTSP5_Perusasennus.

ADSL-modeemi jakaa LAN-reitittimelle/kytkimelle ip-osoitteen (192.168.0.100). Lähiverkkoon päin LAN-reititin/kytkin näkyy ip-osoitteessa 192.168.1.1. Tämä LAN-reititin/kytkin tarjoaa myös nimipalvelut.

Palvelin, jossa on LTSP5-ympäristö, on 192.168.1.101.

Palvelin, jossa on openLDAP, on 192.168.1.102.

Pääte, jolle on annettu kiinteä ip-osoite MAC-osoitteen perusteella, on 192.168.1.200. Pääte myös kirjautuu automaattisesti.

Tässä ohjeessa on käytetty seuraavanlaisia asetustiedostoja.
