kopt(8) System Manager's Manual kopt(8)NAME
kopt - Displays a menu of optional kernel components that can be selected to build into the kernel
SYNOPSIS
/usr/sbin/kopt
DESCRIPTION
When you invoke the kopt command, a menu of optional kernel components is displayed where you specify the kernel components you want to
build into the kernel. Individual selections are separated by a space. The kernel components shown on the menu depend upon the software
subsets that are installed on your system.
EXAMPLES
The following example selects two kernel components to build into the kernel # /usr/sbin/kopt
*** KERNEL OPTION SELECTION ***
Selection Kernel Option ---------------------------------------------------------------
1 Reserve Kernel Debug Space
2 Streams Socket Coexistence (DLPI & STRIFNET)
3 X/Open Transport Interface (XTISO)
4 ISO 9660 Compact Disc File System (CDFS)
5 All of the above
6 None of the above ---------------------------------------------------------------
Enter the selection number for each kernel option you want. For example, 1 3 : 2 4

pmerge - Builds a network bootable kernel.
SYNOPSIS
/usr/sys/bin/pmerge bootfile kernel.name new.kernel
DESCRIPTION
The kernel, vmunix, is not bootable over the network. The pmerge utility prepends the bootfile onto the kernel image (kernel.name) to cre-
ate a new operating system image (new.kernel) that is bootable over the network.
Instead of a booting a network loadable kernel, it is sometimes desired to bootstrap link a kernel over the network. In this case, (ker-
nel.name) is the name of the sysconfigtab file on the server containing the list of modules to be loaded to the client. These modules are
then linked to create a bootable kernel on the client.
The pmerge utility is used by doconfig(8) to create a bootable operating system for dataless management services (DMS) client systems to
boot over the network. The pmerge utility is automatically invoked by doconfig(8) during the kernel build process and should not be invoked
independently.
The pmerge utility is located in /var/adm/dms/dmsn.alpha/root/usr/sys/bin on the DMS server.

I want to set timout for a socket, but these do not work:

I create a program that need a timeout on both send() and recv() function, but I found that SO_SNDTIMEO doesn't work but SO_RCVTIMEO works!!

Please take a look on following code:
s = socket(PF_INET, SOCK_STREAM, 0); //socket
fcntl(s, F_SETFL, O_NONBLOCK); //set socket to nonblock
retry_conn:
ret = connect(s, (struct sockaddr *)&serv_addr, sizeof(struct sockaddr_in)); // try to connect, for sure... (7 Replies)
