Tcpip

Socket manager

Syntax:

Socket [-d flag...] [-f] [-L] [-l num]
       [-m pool_num, pool_size] [-t num]
       [-v num] [hostname]

Options:

-d flag...

Set the specified flags, where flag can be:

forward

Enable gateway support. You should set this flag whenever a QNX host has more than one link interface defined and datagrams must be forwarded from one interface to another (e.g. a host with multiple Ethernet interfaces, or a combination of Ethernet and SLIP interfaces).

-f

Don't go automatically to the background.

-L

Register locally only.

-l num

Set the value of SOMAXCONN (minimum from <sys/socket.h>)

-m pool_num, pool_size

Specify the number and size of memory pools in shared memory. The default is 64,65536 i.e. it specifies a maximum of 64 pools where each pool is 65536 bytes. In most cases, you don't need to change this value.

-t num

Allocate the specified number of threads. The default is 48; in most cases, you don't need to change this value.

-v num

Specify number of virtual packet interfaces allowed (default is 0).

hostname

The name of the local host, as defined in the /etc/hosts file.

Description:

The Socket utility implements the following networking protocols used in TCP/IP for QNX:

• ARP
• ICMP
• IP
• NFS
• TCP
• UDP

Socket also provides an interface to the socket library; functions in this library can make use of the above protocols.

Files:

/etc/hosts file

Hostname database.
