It started as a very simple idea: have internet access available in all rooms of the apartment. As simple as that. OK, I wanted to have both wired and wireless internet access (just in case – having wires instead of thin air carrying over data  seems still more convincing for me).

Seriously, although it’s very easy to set up wireless network access, it still has some limitations like low(er) speed and (higher) latency. Of course, nowadays you can get wi-fi routers with more bandwidth than 54 mbit/s but I want to stay within my (low) budget and since I got my DSL modem for free from my ISP and it has built-in wi-fi , it makes no sense to buy a whole new device just to get more wi-fi speed. So I had to settle with what I got for free…On the other hand, the DSL modem I got is quite a nice gadget with a rich functionality – a Fritz!box 7240 produced by a German company called AVM. Among others it also act as a DECT phone base station, supports dynamic DNS and allows some fancy phone features including using your cheap VOIP account with your regular phone handset without having your computer running.

Fractional replication could be useful if you want to expose only a small set of the attributes to the wider audience. Apart from that it can significantly cut down the size of the database which makes it easier to fit in the memory of the 32-bit systems.

This article uses the existing supplier-consumer setup as a basis and converts it to the fractional replication mode. In the article which describes the supplier-consumer setup you would find the detailed explanation for the replication agreement attribute values to which we refer in this article under signs < and >.

Although I have published an article with a very similar content it does not cover another common use-case. Namely, I have wrote how to setup a multi-master replication but now I will describe another case which is single-master replication (one supplier and one consumer). This case is very similar to the MMR but simpler.

Kompanija peta, zemlja treca

Kraj ove price se zavrsava novom emigracijom i pocetkom nekog novog zivota, po treci put. Iako nemam sta da napisem o pocetku, ovo je prica o kraju koja ce se nastaviti za par meseci.

Kompanija druga, zemlja prva

Da je samo stres ono sta je nestalo, opet bi bio veliki korak napred. No pored stresa, nestalo je i rigidno radno vreme, (neplaceno) prekovremeno, a uz sve to sam bio okruzen prijatnom ekipom i korektnim sefom.

Ovaj clanak pisem kao podsetnik sebi zasto sam tu gde sam kako u profesionalnom pogledu tako i zivotnom s obzirom da su mi profesionalne odluke najvise uticale na promene u zivotu. U proteklih 7 godina promenio sam dve drzave i cetiri firme, sada se nalazim u trecoj zemlji i petoj firmi. Svaka od tih promena je pocinjala uzbudjenjem i zavrsavala se razocarenjem. Razocarenje je nekad dolazilo pre, nekad kasnije, ali je uvek predstavljalo uvod u novi korak u zivotu i nove promene.

In case you are to perform an upgrade, a useful thing to have is a CLI way to disable and enable a replication agreement. Here’s how to do it:

• create a LDIF file named disableAgreement.ldif which would modify the replication agreement:

dn: cn=AGREEMENT_NAME, cn=replica, cn=SUFFIX, cn=mapping tree, cn=config
changetype: modify
add: ds5AgreementEnable
ds5AgreementEnable: off

• import the file:

ldapmodify -h HOST -p PORT -D rootDN -w password -f disableAgreement.ldif

To enable it:

• create a new file, enableAgreement.ldif with the following contents:

dn: cn=AGREEMENT_NAME, cn=replica, cn=SUFFIX, cn=mapping tree, cn=config
changetype: modify
replace: ds5AgreementEnable
ds5AgreementEnable: on

• import the file

ldapmodify -h HOST -p PORT -D rootDN -w password -f disableAgreement.ldif

Robotiku kao hobi sam otkrio smišljajući efikasan način da učim programiranje. Učiti neki programski jezik iz knjige nije toliko teško i daje privid da se razume gradivo, međutim problem nastaje kada poželite to znanje da stavite u pogon i napravite nešto korisno, a nemate ideju šta bi to moglo da bude. Koji god da je vaš razlog, jednog je sigurno – slede vam sati zabave i učenja, ali pitanje je odakle i kako početi? Pročitaj više…

Two years ago I have started a series of articles regarding manipulating Sun Java System Directory Server 5.2 from the command line. This article continues the series and describes the process of adding a new suffix and database to the installation via LDIF. Pročitaj više…

IT sertifikati su često meta kritike i hvale, nekada sa razlogom, a nekada bez. U moru diskusija za i protiv teško je dobro odmeriti koliko je to dobro za vas, a u krajnjoj liniji ono šta vama služi svrsi ne mora da bude dovoljno dobar razlog nekom drugom i obrnuto. Zato mi je cilj da u ovom članku prenesem moja iskustva i ukažem na neke specifičnosti koje bi ljudima sa našeg podneblja bile prednost. Pročitaj više…
