How to change the ndd parameters wrt SOCKET

[Singaravel_1]

Hi All,

If any one can provide information about how to chek and change the following ndd parameters, and also please let me know if changing any SOCKET related parameter will impact the system operations ?

The output presented here is a excerpt from "# ndd -h supt" command

SOCKET:
socket_buf_max - Sets maximum socket buffer size for AF_UNIX sockets.
socket_caching_tcp - Controls socket caching for TCP sockets.
socket_qlimit_max - Sets maximum number of connection requests for non-AF_INET sockets.
socket_udp_rcvbuf_default - Sets the default receive buffer size for UDP sockets.
socket_udp_sndbuf_default - Sets the default send buffer size for UDP sockets.


Please help in solving the issue.

Thanks in Advance,
Singaravel

You will have to set up the /etc/rc.config.d/nddconf

Hi,

in order to check those ndd parameters

ndd -get /dev/sockets socket_buf_max

and so on....

In order to set them

ndd -set /dev/sockets socket_buf_max

This will change the ndd parameter socket_buf_max.

Then insert the new value into /etc/rc.config.d/nddconf like the following:

TRANSPORT_NAME[0]=sockets
NDD_NAME[0]=socket_buf_max
NDD_VALUE[0]=

0 is just a progressive index.

HTH.

Best regards,
Fabio
