Accenture MDR Quick Start Guide for Unix® OS

This quick start guide will help Accenture MDR customers configure Unix® Servers to send logs to the Log collection Platform (LCP).

This document includes the following topics:

Supported Versions

A list of supported versions is available in the Accenture MDR Supported Products List document (Accenture_MDR_Supported_Products_List.xlsx) which can be found in Accenture MDR Portal.

Port Requirements

Table 1-1: Port requirements for LCP communication.

 Configuring Unix OS

You can configure Unix OS devices using different syslog daemons to send event logs to the LCP.

• For syslogd configuration, see Configuring Syslog Message Forwarding Using syslogd

• For rsyslogd configuration, see Configuring Syslog Message Forwarding Using rsyslogd

• For syslog-ng configuration, see Configuring Syslog Message Forwarding Using syslog-ng

• For Nokia IPSO syslog configuration, see Configuring Syslog Message Forwarding for Nokia IPSO

In addition, we recommend configuring iptables and auditd logging.

• To configure iptables, see Configuring Logging for Linux iptables

• To configure auditd logging, see Configuring Syslog Plugin for auditd

 Note: Additional configuration is required for IBM AIX and SUSE Linux 12.

• To configure FTP to log FTP sessions and debug information for IBM AIX, see Configuring FTP to Log FTP Sessions and Debug Information for IBM AIX

• To configure event date format for SUSE Linux 12, see Configuring Event Date Format for SUSE Linux

Configuring Syslog Message Forwarding Using syslogd

To configure syslog message forwarding using syslogd:

1. From a Unix server, login with root privileges.

2. To stop syslogd, at the command prompt, type the following command as required:

1. Use a text editor, such as vi, to open and edit the

/etc/syslog.conf file.

Add the following line in the syslog.conf file: *.info  @IP_address_of_the_LCP

For example: *.info @192.0.2.1, where 192.0.2.1 is the IP address of the LCP.

2. Save and close the syslog.conf file.

3. To start or restart syslogd, type the following command as required:

​

Configuring Syslog Message Forwarding Using rsyslogd (RHEL/Huawei EulerOS)

To configure syslog message forwarding using rsyslogd:

1. From a Unix server, login with root privileges.

2. To stop rsyslogd, at a command prompt, type the following command:

•  For SUSE Linux and Ubuntu Linux: service rsyslog stop

•  For other Linux distributions: /etc/init.d/rsyslog stop

Use a text editor, such as vi, to open and edit the following file:

• For Ubuntu Linux: /etc/rsyslog.d/50-default.conf 

• For other Linux distributions: /etc/rsyslog.conf

Add one of the following lines at the end of the rsyslog.conf file:

• For UDP forwarding, add *.info     @IP_address_of_the_LCP

• For TCP forwarding, add *.info     @@IP_address_of_the_LCP

Examples:

For UDP forwarding: *.info    @192.0.2.1, where 192.0.2.1 is the IP address of the LCP.

For TCP forwarding: *.info    @@192.0.2.1, where 192.0.2.1 is the IP address of the LCP.

1. Save and close the rsyslog.conf file.

2. To restart rsyslogd, at a command prompt, type the following command:

•  For SUSE Linux and Ubuntu Linux: service rsyslog restart

•  For other Linux distributions: /etc/init.d/rsyslog restart

Configuring Syslog Message Forwarding Using syslog-ng

To configure syslog message forwarding using syslog-ng:

1. From a Unix server, login with root privileges.

2. Use a text editor, such as vi, to open and edit the following file: /etc/syslog-ng/syslog-ng.conf

3. Add the following lines in the syslog-ng.conf file:

destination d_label_for_lcp { udp(lcp_ip_address port(preferred_port_number)); };

filter f_label_that_identifies_the_filter { facility(info..emerg) and not facility (mail,cron); };

log { source(src); filter(f_label_that_identifies_the_filter); destination(d_label_for_lcp); };

For example:

destination d_lcp { udp(192.0.2.1 port(514)); }; filter f_lcpfilter { facility(info..emerg) and not facility (mail,cron); }; log { source(src); filter(f_lcpfilter); destination(d_lcp); };

Where:

• udp - Protocol configured.

• 192.0.2.1 - IP address of the LCP.

• 514 - Default port on which the LCP is configured to listen (preferred).

• source (src) - default syslog-ng, "source src" should already be defined in the syslog-ng.conf file.

• The filter parameter is optional.

 Note: To configure TCP protocol, follow steps 1-3 and use "tcp" instead of "udp". Also use "601" instead of "514", where 601 is the default TCP port. 

1. Save and close the syslog-ng.conf file.

2. To restart syslog-ng, at a command prompt, type the following command: service syslog restart

Configuring Logging for Linux iptables

 Linux iptables use the following options to set the logging format for events: 

• -- log-level

• -- log-prefix

• -- log-tcp-sequence

• -- log-tcp-options

• -- log-ip-options

Sample iptables Rule

iptables -A INPUT -i eth0 -p tcp -s 192.0.2.1--dport 22 -j LOG --log-prefix "IPT: SSH DENY "--log-level info --log-tcp-sequence --log-tcp-options--log-ip-options

Configuring Syslog Plugin for auditd

 Note: If syslog plugin for auditd is not installed on the server, refer to the vendor repository for installation.

 To configure syslog plugin for auditd:

1. From a Unix server, login with root privileges.

2. To stop the audit process, at a command prompt, type the following command: /etc/init.d/auditd stop

3. Use a text editor, such as vi, to open and edit the following file: /etc/audisp/plugins.d/syslog.conf

4. Add the following line to the /etc/audisp/plugins.d/syslog.conf file: active = yes

5. Save and close the /etc/audisp/plugins.d/syslog.conf file.

6. To restart the audit process, at a command prompt, type the following command: /etc/init.d/auditd start

Configuring FTP to Log FTP Sessions and Debug Information for IBM AIX

 To configure FTP to log FTP sessions and debug information for IBM AIX:

1. On an AIX server, at the Unix prompt, login with root privileges.

2. Use an editor, such as vi, to open and edit the following file: /etc/inetd.conf

3. Configure the FTP daemon with -l and -d parameters. A sample configuration is as follows: ftp stream tcp nowait root /usr/sbin/ftpd -l -d

4. Save and close the inetd.conf file.

5. Stop and restart the FTP subserver by typing the following commands:

• stopsrc -t ftp

• startsrc -t ftp

Configuring Syslog Message Forwarding for Nokia IPSO

To configure syslog message forwarding for Nokia IPSO:

1. Login to the Nokia Network Voyager Web console with root privileges.

2. Click System Configuration > System Logging.

3. Under Remote system logging, in the Add new remote IP address to log to field, enter the IP address of the LCP.

4. Click Apply. The IP address of the LCP should appear in the list.

5. From the Log at or above severity list, select Info.

6. Click Apply and then Save.

Configuring Event Date Format for SUSE Linux

To configure event date format for SUSE Linux:

1. From a SUSE Linux server, login with root privileges.

2. To stop rsyslogd, at a command prompt, type the command: service rsyslog stop-

3. Use a text editor, such as vi, to open and edit the following file: /etc/rsyslog.conf

4. Add the following line to the /etc/rsyslog.conf file: $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

5. Save and close the /etc/rsyslog.conf file.

6. To restart rsyslog, at a command prompt, type the command: service rsyslog start
