  • Centralizzare i log mediante Elasticsearch, Logstash e Kibana – Mia mamma usa Linux! – Uno dei principali problemi che si rilevano in fase di debug delle anomalie relative ad applicazioni è la frammentazione delle informazioni. Tanti log, buona parte dei quali inutili, sono sparsi ovunque nelle macchine interessate all’erogazione di questo o quel servizio.
    Tipicamente quando si tratta di servizi ripartiti su più macchine è sempre necessario aprire diverse console all’interno delle quali, per ciascuna macchina, il (o i) file di log vengono aperti, filtrati stampati e via così, sino ad ottenere una situazione degna di Sherlock Holmes, in cui solo consumati ed abili detective riescono a trovare l’indizio che sfugge ai più.

    Esiste però una via migliore per gestire enormi quantità di log in una forma centralizzata, facilmente ricercabile e che usi un’interfaccia gradevole. Si tratta della combinazione di tre software: Elasticsearch, Logstash e Kibana.

  • using mod_auth_kerb and Windows 2000/2003/2008R2 as KDC – This tutorial contains my knowledge about using Apache/mod_auh_kerb and Windows 2000/2003/2008R2 as KDC.
  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

    On the Windows side, Windows XP and Windows 2007 have been tested against Windows 2008, and Windows XP against Windows 2003.

I've added paragraphs like this where necessary. Enjoy! :-)
