Gpg4win (GNU Privacy Guard for Windows) is an encryption software for files and emails.
What is Gpg4win?
Gpg4win enables users to securely transport emails and files with the help of encryption and digital signatures. Encryption protects the contents against an unwanted party reading it. Digital signatures make sure that it was not modified and comes from a specific sender.
Sometimes you need to encrypt some files or messages to prevent accessing them by unathorized persons. There are several standards and software for this purpose, but the most popular standard that adopted on the...
Sometimes you need to combine two or more LDAP directories with same suffixes to one directory or you just need to have a proxy. My first attempts to combine two OpenLDAP directories was to make replication from two different sources. This solution however has some disadvantages. First of all: to have syncprov replication your environment must be uniform, this means all source servers and proxy needs to be OpenLDAP. Second: I observed that this is not so stable, because of mentioned earlier issues with OpenLDAP replication.
Sometimes you need to set some attributes as unique, for example: if LDAP contains system users, then uid attribute shouldn’t repeat in whole system. OpenDJ is equipped with proper plugin, but it’s not enabled...
This is a description of upgrade Sony Ericsson Xperia X10 Mini Pro to newest available for now version of Cyanogen Froyo system developed by XDA Developers.
I will perform update from CM 5.0 Final Release, because I have already done upgrade to CM 5.0 from the factory supplied X10 Mini Pro Android v 2.1. The fact is that the first update conferred the most trouble, because you need to ‘root’ your smartphone, install xRecovery software, and then go for upgrade. However, for now I describe the process of upgrading from 5.0 to 6.01.
(Polski) Ostatnim razem pisałem o uwierzytelnianiu użytkowników w katalogu LDAP aby umożliwiać im odbieranie i nadawanie poczty. Teraz nadszedł czas aby skonfigurować Postfixa aby dostarczał pocztę do właściwych skrzynek.
Jeśli sam kompilujesz Postfixa musisz pamiętać o dodaniu do niego wsparcia dla LDAP. Mój opis tym razem bazuje na Ubuntu, więc trzeba tylko zainstalować odpowiedni pakiet postfix-ldap:
$ sudo -i
# apt-get install postfix-ldap
To załatwi sprawę wsparcia map
ldap: w Postfixie.
Teraz idziemy do konfiguracji Postfixa:
During switching LDAP directory to new environment with newer version of OpenLDAP (2.4.25) and new BerkeleyDB (5.1.25), I received following error message:
Program version 5.1 doesn't match environment version 4.7 database ... cannot be opened, err -30969. Restore from backup! bdb(...): txn_checkpoint interface requires an environment configured for the transaction subsystem bdb_db_close: database "...": txn_checkpoint failed: Invalid argument (22). backend_startup_one (type=hdb, suffix="..."): bi_db_open failed! (-30969) bdb_db_close: database "...": alock_close failed
This means that you need to upgrade BerkeleyDB. Because this is not OpenLDAP specific, but rather BerkeleyDB specific, I decided to describe how to fix this issue. First of all let’s make a backup:
