Network Requirements

# useradd -g ttaserv -s /bin/sh -d /home/ttaserv -m ttaserv

# passwd -l ttasys

# passwd -l ttaserv

To check whether the ttasys and ttaserv user accounts are correctly set up on your system, use the

following commands.

# su ttasys -c "/usr/bin/id -a"

# su ttaserv -c "/usr/bin/id -a"

If your system is set up correctly, the command output should be similar to the following examples.

uid=1002(ttaserv) gid=1000(ttaserv) groups=1000(ttaserv)

uid=1003(ttasys) gid=1000(ttaserv) groups=1000(ttaserv)

2.1.6. Network Requirements

You must configure your network for use with SGD. The following are the main requirements:

• Hosts must have Domain Name System (DNS) entries that can be resolved by all clients.

• DNS lookups and reverse lookups for a host must always succeed.

• All client devices must use DNS.

• When you install SGD, you are asked for the DNS name to use for the SGD server. The DNS name

must meet the following requirements:

• In a network containing a firewall, use the DNS name that the SGD host is known as inside the

firewall.

• Always use fully-qualified DNS names for the SGD host. For example, boston.example.com.

The Oracle Secure Global Desktop Administration Guide for Release 4.7 has detailed information about

all the ports used by SGD and how to use SGD with firewalls. The following information lists the common

ports used.

Client devices must be able to make Transmission Control Protocol/Internet Protocol (TCP/IP) connections

to SGD on the following TCP ports:

• 80 - For HTTP connections between client devices and the SGD web server. The port number can vary

depending on the port selected on installation.

• 443 - For HTTP over Secure Sockets Layer (HTTPS) connections between client devices and the SGD

web server.

• 3144 - For standard (unencrypted) connections between the SGD Client and the SGD server.

• 5307 - For secure connections between the SGD Client and the SGD server. Secure connections use

Secure Sockets Layer (SSL).

Note

For a default installation in secure mode, where you enable SGD security services

and use HTTPS, only ports 443 and 5307 must be open in the firewall.

For an installation in standard mode, where connections are not secured, ports 80,

3144, and 5307 must be open in the firewall. This is because the SGD Client initially
