Full Discussion: UNIX - AIX - Syslog messages

AIX has at least 3 logging facilities and 1 auditing facility.

Logging facilities are:
- syslog
- errlog
- alog

All 3 facilities make a little different things. Through alog you can see e.g. boot-time or console messages. Errlog logs mostly hardware-related messages. Syslog is a standard UNIX logging mechanism.

If you do a security assessment, the usual question is - what must be logged in your branch and in your country? There are a lot of different regulations for different branches (financial, healthcare, stock exchanges, human resources, and so on) and in different countries - rules for an US-based company are not the same as rules for an European- or a Chinese company.

All logging and auditing facilities must be configured according to your local requirements. It is not where a sysadmin has right to say something. It is your local authorities who say the word.

After you have your requirements it is easier to decide what should be written in a configuration file to receive the information you require on the central logging server. If you can't analyze the received information, because you've never seen UNIX logs, you have to hire some experienced guy or can try to post example log entries (if they are not tooo sensitive for your organization) here and forum members will try to explain the logs to you.

NAME
Net::Server::Log::Sys::Syslog - log via Syslog SYNOPSIS
use base qw(Net::Server::PreFork); __PACKAGE__->run( log_file => 'Sys::Syslog', syslog_ident => 'myapp', ); DESCRIPTION
This module provides Sys::Syslog logging to the Net::Server system. CONFIGURATION
log_file To begin using Sys::Syslog logging, simply set the Net::Server log_file configuration parameter to "Sys::Syslog". If the magic name "Sys::Syslog" is used, all logging will take place via the Sys::Syslog module. If syslog is used the parameters "syslog_logsock", "syslog_ident", and "syslog_logopt",and "syslog_facility" may also be defined. syslog_logsock Only available if "log_file" is equal to "Sys::Syslog". May be either unix, inet, native, console, stream, udp, or tcp, or an arrayref of the types to try. Default is "unix" if the version of Sys::Syslog < 0.15 - otherwise the default is to not call setlogsock. See Sys::Syslog. syslog_ident Only available if "log_file" is equal to "Sys::Syslog". Id to prepend on syslog entries. Default is "net_server". See Sys::Syslog. syslog_logopt Only available if "log_file" is equal to "Sys::Syslog". May be either zero or more of "pid","cons","ndelay","nowait". Default is "pid". See Sys::Syslog. syslog_facility Only available if "log_file" is equal to "Sys::Syslog". See Sys::Syslog and syslog. Default is "daemon". DEFAULT ARGUMENTS FOR Net::Server The following arguments are available in the default "Net::Server" or "Net::Server::Single" modules. (Other personalities may use additional parameters and may optionally not use parameters from the base class.) Key Value Default ## syslog parameters (if log_file eq Sys::Syslog) syslog_logsock (native|unix|inet|udp |tcp|stream|console) unix (on Sys::Syslog < 0.15) syslog_ident "identity" "net_server" syslog_logopt (cons|ndelay|nowait|pid) pid syslog_facility w+ daemon METHODS
"initialize" This method is called during the initilize_logging method of Net::Server. It returns a single code ref that will be stored under the log_function property of the Net::Server object. That code ref takes log_level and message as arguments and calls the initialized log4perl system. "handle_log_error" This method is called if the log_function fails for some reason. It is passed the Net::Server object, the error that occurred while logging and an arrayref containing the log level and the message. In turn, this calls the legacy Net::Server::handle_syslog_error method. LICENCE
