Chapter 4: Configuring the High-Level Network

4-120

To set connection limits on services

Use the following syntax to set the maximum number of concurrent

connections allowed on a service. Note that you can configure this setting

for one or more services.

b service <service> [...<service>] limit <max conn>

To turn off a connection limit for one or more services, use the same

command, setting the <max conn> parameter to 0 (zero) like this:

b service <service> [...<service>] limit 0

To enable or disable TCP for services

You can enable or disable TCP for specific services. The default setting for

all services is enabled. Use the following syntax to disable TCP for one or

more services:

b service <service> [...<service>] tcp disable

To re-enable TCP, use this syntax:

b service <service> [...<service>] tcp enable

To enable or disable UDP for services

You can enable or disable UDP for specific services. The default setting for

all services is disabled. Use the following syntax to enable UDP for one or

more services:

b service <service> [...<service>] udp enable

To disable UDP, use this syntax:

b service <service> [...<service>] udp disable

To set the idle connection timeout for TCP traffic

To set the TCP timeout on one or more services, where the <seconds>

parameter is the number of seconds before an idle connection is dropped,

use the following syntax:

b service <service> [<service>...] timeout tcp <seconds>

For example, the following command sets the TCP timeout to 300 seconds

for port 53:

b service 53 timeout tcp 300

To turn off TCP timeout for a service, use the above command, setting the

<seconds> parameter to zero:

b service 53 timeout tcp 0

To set the idle connection timeout for UDP traffic

To set the UDP timeout on one or more services, where the <seconds>

parameter is the number of seconds before an idle connection is dropped,

use the following syntax:

b service <service> [<service>...] timeout udp <seconds>
