Initial Setup of External Firewalls and Load Balancers

#	sec.name	source	community
com2sec	local	localhost	public
com2sec	mynetwork	0.0.0.0	public

Note

Setting to 0.0.0.0 allows all IPs to poll the NetScaler server.

b. Map the security names into group names:

#group.name sec.model sec.name

group	MyRWGroup	v1	local
group	MyRWGroup	v2c	local
group	MyROGroup	v1	mynetwork
group	MyROGroup	v2c	mynetwork

c.Create a view to allow the groups to have the permission to:

incl/excl subtree mask view all included .1

d. Grant access with different write permissions to the two groups to the view you created.

# context	sec.model		sec.level	prefix	read	write	notif
access	MyROGroup ""		any noauth	exact	all	none	none
access	MyRWGroup	""	any noauth	exact	all	all	all

3. Unblock SNMP in iptables.

iptables -A INPUT -p udp --dport 161 -j ACCEPT

4. Start the SNMP service:

service snmpd start

5. Ensure that the SNMP service is started automatically during the system startup:

chkconfig snmpd on

16.7.3. Initial Setup of External Firewalls and Load Balancers

When the first VM is created for a new account, CloudPlatform programs the external firewall and load balancer to work with the VM. The following objects are created on the firewall:

•A new logical interface to connect to the account's private VLAN. The interface IP is always the first IP of the account's private subnet (e.g. 10.1.1.1).

•A source NAT rule that forwards all outgoing traffic from the account's private VLAN to the public Internet, using the account's public IP address as the source address

•A firewall filter counter that measures the number of bytes of outgoing traffic for the account

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
