Introduction

The PIX Firewall delivers unprecedented levels of security, performance, and reliability, including robust, enterprise-class security services such as the following:

•Stateful inspection security, based on state-of-the-art Adaptive Security Algorithm (ASA)

•Over 100 predefined applications, services, and protocols for flexible access control

•Virtual Private Networking (VPN) for secure remote network access using IKE/IPSec standards

•Intrusion protection from over 55 different network-based attacks

•URL filtering of outbound web traffic through third-party server support

•Network Address Translation (NAT) and Port Address Translation Support (PAT)

Additionally, PIX Firewall Version 6.3 software supports Cisco PIX Device Manager (PDM) Version 3.0 and adds enhancements to features introduced in earlier releases.

System Requirements

The sections that follow list the system requirements for operating a PIX Firewall with Version 6.3 software.

Memory Requirements

The PIX 501 has 16 MB of RAM and will operate correctly with Version 6.1(1) and higher, while all other
PIX Firewall platforms continue to require at least 32 MB of RAM (and therefore are also compatible with version 6.1(1) and higher).

In addition, all units except the PIX 501 and PIX 506E require 16 MB of Flash memory to boot. (The PIX 501 and PIX 506E have 8 MB of Flash memory, which works correctly with Version 6.1(1) and higher.)

Table 1 lists Flash memory requirements for this release.

Software Requirements

Version 6.3 requires the following:

1. The PIX Firewall image no longer fits on a diskette. If you are using a PIX Firewall unit with a diskette drive, you need to download the Boothelper file from Cisco Connection Online (CCO) to let you download the PIX Firewall image with TFTP.

2. If you are upgrading from Version 4 or earlier and want to use the Auto Update, IPSec, SSH, PDM, or VPN features or commands, you must have a new 56-bit DES activation key. Before getting a new activation key, write down your old key in case you want to retrograde to Version 4. You can have a new 56-bit DES activation key sent to you by completing the form at the following website:

3. If you are upgrading from a previous PIX Firewall version, save your configuration and write down your activation key and serial number. Refer to 'Upgrading to a New Software Release' for new installation requirements.

Maximum Recommended Configuration File Size

For the PIX 525 and PIX 535, the maximum configuration file size limit is increased to 2 MB for PIX Firewall software Versions 5.3(2) and later. For other PIX Firewall platforms, the maximum configuration file size limit is 1 MB. Earlier versions of the PIX 501 are limited to a 256 KB configuration file size. If you are using PIX Device Manager (PDM), we recommend no more than a 100 KB configuration file because larger configuration files can interfere with the performance of PDM on your workstation.

While configuration files up to 2 MB are now supported on the PIX 525 and PIX 535, be aware that such large configuration files can reduce system performance. For example, a large configuration file is likely to noticeably slow execution times in the following situations:

•While executing commands such as write term and show conf

•Failover (the configuration synchronization time)

•During a system reload

The optimal configuration file size for use with PDM is less than 100 KB (which is approximately 1500 lines). Please take these considerations into account when planning and implementing your configuration.

Important Notes in Release 6.3

This section describes important notes for Version 6.3.

Simultaneous PPTP Connection Limitation

There is a hardware limitation of 128 concurrent sessions in PIX 6.x. If you subtract one for the PPTP listening socket, the maximum number of simultaneous PPTP connections is127.

Attempts to connect more than 127 connections with PIX 6.x generates the following error message:

That is how we can generate SSH key in Windows using putty.

ACL Source Address Change When an Alias is Configured

When the alias command is used for destination address translation, an inbound message originating from the foreign_ip source address is translated to the dnat_ip address. If you configure an inbound ACL with an address defined by the alias command, you must use the foreign_ip address as the ACL source address instead of the dnat_ip address, as was used in Release 6.2. The ACL check is now done before the translation occurs, which is consistent with the way the firewall treats other NATed addresses in ACLs.

Interface Settings on the PIX 501 and PIX 506E

With the PIX Firewall Version 6.3, the settings for the following interfaces have been updated as follows:

•PIX 501 outside interface (port 0) - 10/100 Mbps half or full duplex

•PIX 501 inside interface - 10/100 Mbps half or full duplex

•PIX 506E inside interface - 10/100 Mbps half or full duplex

•PIX 506E outside interface - 10/100 Mbps half or full duplex

Note When upgrading the PIX 501 to Version 6.3, the inside interface is automatically upgraded to 100 Mbps full duplex. During the upgrade process the system displays the message 'ethernet1 interface can only be set to 100full.'

Upgrading the PIX 506 and the PIX 515

When upgrading a classic PIX 506 or PIX 515 (the non 'E' versions) to PIX Firewall OS Version 6.3, the following message(s) might appear when rebooting the PIX Firewall for the first time after the upgrade:

ethernet0 was not idle during boot.

ethernet1 was not idle during boot.

These messages (possibly one per interface) will be followed by a reboot. This is a one-time event and is a normal part of the upgrade on these platforms.

Easy VPN Remote and Easy VPN Server

The PIX 501 and PIX 506/506E are both Easy VPN Remote and Easy VPN Server devices. The PIX 515/515E, PIX 525, and PIX 535 act as Easy VPN Servers only.

The PIX 501 and PIX 506/506E can act as Easy VPN Remote devices or Easy VPN Servers so that they can be used either as a client device or VPN headend in a remote office installation. The PIX 515/515E, PIX 525, and PIX 535 act as Easy VPN Servers only because the capacity of these devices makes them appropriate VPN headends for higher-traffic environments.

PIX 535 Interfaces

These practices must be followed to achieve the best possible system performance on the PIX 535:

•PIX-1GE-66 interface cards should be installed first in the 64-bit/66 MHz buses before they are installed in the 32-bit/33 MHz bus. If more than four PIX-1GE-66 cards are needed, they may be installed in the 32-bit/33 MHz bus but with limited potential throughput.

•PIX-VACPLUS should be installed in a 64-bit/66 MHz bus to avoid degraded throughput.

•PIX-1GE and PIX-1FE cards should be installed first in the 32-bit/33 MHz bus before they are installed in the 64-bit/66 MHz buses. If more than five PIX-1GE and/or PIX-1FE cards are needed, they may be installed in a 64-bit/66 MHz bus but doing so will lower that bus speed and limit the potential throughput of any PIX-1GE-66 card installed in that bus.

The PIX-1GE Gigabit Ethernet adaptor is supported in the PIX 535; however, its use is strongly discouraged because maximum system performance with the PIX-1GE card is much slower than that with the PIX-1GE-66 card. The software displays a warning at boot time if a PIX-1GE is detected.

Table 2 summarizes the performance considerations of the different interface card combinations.

The SSH Host key is used to distinguish monitored hosts, there should not be duplicate SSH keys. A key can be duplicated if a server is cloned. This section describes how to change the SSH host key for a particular host, eliminating the events and alarms generated when duplicate hosts are detected.

The following steps must be performed:

• Generate a new SSH key for the monitored host.

• Edit the monitoring agent's configuration.

• Edit the hostid in the MySQL Enterprise Service Manager repository.

On UNIX, Linux and Mac OS platforms, use the ssh-keygen utility. On Microsoft Windows platforms, there are several tools, but this example uses puttygen.

Generate Ssh Key Github

To generate a new SSH key for the monitored host, do the following:

Cisco Pix 6.3 Generate Ssh Key Login

1. On the monitored host, generate an SSH key. For example:

   If using puttygen, click Generate and follow the instructions on-screen.

   The key can be generated using RSA (SSH1 or SSH2), DSA, or ECDSA. All are supported by MySQL Enterprise Monitor.

2. Retrieve the key fingerprint.

   The fingerprint is an alphanumeric string similar to the following:

   On UNIX-based platforms, retrive this value with the following command:

   On Windows platforms, using puttygen, this value is in the Key Fingerprint field.

3. Stop the monitoring agent.

4. Open the monitoring agent's bootstrap.properties configuration file, and add, or edit, the following value:

   For example, using the fingerprint listed above:

5. On the MySQL Enterprise Service Manager machine, edit the hostid value in the repository:

6. Restart the monitoring agent.
