all ports on the switch are in the same vlan and these ports are working fine. when I try to deconnect hostA from switch and replace it by hostB on the same port, hostB can communicate with hostC (pings are working fine). so i think that the issue come from hostA network config.
I'm pinging IP address and not hostnames
Howto check if a ethernet interface is up?
It's impossible to determine via the ipaddress i have learned, or?
Can someone please give me a hint on howto do?

I need to install ethernet card drivers on intel machine. How can i know which Ethernet card interface (sfe,rh,rtls...) is it? How can i know the speed of that card? How can i know network traffic ? If network traffic is more with that interface what should i do?
Thanks in advance (2 Replies)
Hi All,
I want to configure network into my system.
i tried following in to configure the interface
to find the name of interface

Hi,
is there any method to check the interface collisions on ethernet NIC in AIX. I know that in Solaris it's netstat -i but I've written that in AIX it doesn't show this.

uuid_generate_random
UUID_GENERATE(3) Libuuid API UUID_GENERATE(3)NAME
uuid_generate, uuid_generate_random, uuid_generate_time - create a new unique UUID value
SYNOPSIS
#include <uuid/uuid.h>
void uuid_generate(uuid_t out);
void uuid_generate_random(uuid_t out);
void uuid_generate_time(uuid_t out);
DESCRIPTION
The uuid_generate function creates a new universally unique identifier (UUID). The uuid will be generated based on high-quality randomness
from /dev/urandom, if available. If it is not available, then uuid_generate will use an alternative algorithm which uses the current time,
the local ethernet MAC address (if available), and random data generated using a pseudo-random generator.
The uuid_generate_random function forces the use of the all-random UUID format, even if a high-quality random number generator (i.e.,
/dev/urandom) is not available, in which case a pseudo-random generator will be substituted. Note that the use of a pseudo-random genera-
tor may compromise the uniqueness of UUIDs generated in this fashion.
The uuid_generate_time function forces the use of the alternative algorithm which uses the current time and the local ethernet MAC address
(if available). This algorithm used to be the default one used to generate UUID, but because of the use of the ethernet MAC address, it
can leak information about when and where the UUID was generated. This can cause privacy problems in some applications, so the uuid_gener-
ate function only uses this algorithm if a high-quality source of randomness is not available.
The UUID is 16 bytes (128 bits) long, which gives approximately 3.4x10^38 unique values (there are approximately 10^80 elementary particles
in the universe according to Carl Sagan's Cosmos). The new UUID can reasonably be considered unique among all UUIDs created on the local
system, and among UUIDs created on other systems in the past and in the future.
RETURN VALUE
The newly created UUID is returned in the memory location pointed to by out.
