Hello all,
I have the following question:
if you join a multicast group (with setsockopt() and IP_ADD_MEMBERSHIP) and specify INADDR_ANY as network interface to join on, the kernel is supposed to choose which interface to use (if there are multiple network interfaces, of course).

Double question here ... Running on Debian Etch and Apache 2.0
1) Using mod_proxy and/or mod_proxy_http in apache 2.0.
The basics of using mod_proxy are pretty simple so long as you're using a static config. I'm trying to figure out how to do it dynamically - that is, allow the entry of a... (4 Replies)

Hi all,
I encounter some problem with my e1000g interface running on sol 10. I can't permanently change the auto-nego to disable, if i use ndd commands, it will only stay until the next reboot.
But i can't change the link speed either is set to /etc/init.d/nddconfig or using ndd commands.

Hello,
I'm writing to you because I encountered the following problem. My program displayes all network interfaces that are available in the system, but I would like to add a functionality in which a user can enter a destination address IP (ex. the IP address of the Google search engine) and will...

Hi,
I am using the ce interface on my Solaris 9 server and there is significant packet loss when transmitting large packets. Does anyone have a fix for this?

RHEL 7.0, IPV6
Scenario:
I have routed specific network using network scripts.
1. "ip -6 route show" shows that route has been added. ( with metric 1024)
2. Ping of the specific IP through that route is successful.
3. Now after few days, for some reason, we see that cache route appears for... (3 Replies)

ifmcstat
IFMCSTAT(8) BSD System Manager's Manual IFMCSTAT(8)NAME
ifmcstat -- dump multicast group management statistics per interface
SYNOPSIS
ifmcstat [-i interface] [-f address-family] [-v] [-K] [-M core] [-N system]
DESCRIPTION
The ifmcstat command dumps multicast group information from the kernel.
The following options are supported:
-i interface
specifies the interface to be displayed.
-f address-family
specifies the address family to be displayed; inet, inet6 and link are supported.
-v specifies that link-layer memberships should be printed; they are suppressed by default. It may not be specified for -f link.
Source lists for each group will also be printed.
If specified twice, and kvm(3) is in use, the control plane timers for each interface and the source list counters for each group
will also be printed.
The following options are only available if ifmcstat has been built with support for kvm(3):
-K attempts to use kvm(3) to retrieve the multicast group information.
-M core extracts values associated with the name list from the specified core, instead of the default /dev/kmem.
-N system extracts the name list from the specified kernel instead of the default, which is the kernel image the system has booted from.
IMPLEMENTATION NOTES
ifmcstat will always print the embedded scope IDs of IPv6 multicast group memberships. This is because memberships are always scoped to an
interface.
When run with the -v option, ifmcstat may print multicast MAC addresses twice if they are referenced by a layer 3 protocol.
When run with kvm(3) support, the names of all interfaces configured in the system will be printed in the first column of output, even if no
multicast group memberships are present on those interfaces. The output may also be slightly different, as the kernel data structures are
being traversed with minimal post-processing of the output.
When built without kvm(3) support, the information displayed by ifmcstat is more limited. This support is recommended for debugging pur-
poses. It requires super-user privilege if used to inspect a running kernel.
