I am training to be support on our solaris based network and was wondering why solaris seems to assign the same mac address to all NICs placed in the machine regardless of how many NICs are in there, when i do a ifconfig -a all nics have same MAC.
Presumably this is a feature and there is... (1 Reply)
I run openbsd with 3 NICs,
ep1 is dhcp, interface with internet ip addy
dc0 is 192.168.0.254/24
sis0 is 192.168.0.253/24
My system somehow lags, and some services do not work properly, i want to run a lot of local network services like samba, named, ftp, http, dhcpd, radiusd.

Hi friends,
I installed oracle 10g (10.2.0.2) RAC on 2 IBM p5 570 servers running AIX 5.3ML04 and HACMP5.2 (used Raw devices, not used GPFS). Each server has 4 x 1Gbps ethernet cards (NICs), en0 and en1 for boot address, en2 and en3 for oracle interconnect.
Now i want to merge 2 NICs (en2 and... (1 Reply)
FreeBSD 4.8, Apache 1.3.27 - two NICs, one with a real-world IP plugged into a switch outside the PIX firewall, the other with a private IP plugged into a switch inside the PIX firewall. Apache listens on both IPs. my domain is mydomain.org.
so in /etc/rc.conf i have something like this (these... (10 Replies)
Hi, is there a way in Solaris 8 to determine how many total NIC's say a Sun Sparc box has installed - plumbed or unplumbed - and find out its capable network speeds and MAC address?
I know ifconfig -a but that only shows the plumbed and used interfaces.
thx

I'm looking for a way in RHL 5.1 to use two NICs on one host with two physical IP addresses and map them under one virtual IP address, i.e. NIC 1 10.10.10.1 NIC2 10.10.10.2 VIP 192.168.10.1
Basically I want either one of the NICs to ARP for the VIP. No load balancing required just HA. (2 Replies)
I had the pleasure of having a gig nic given to me this week, which also appears on the hardware list of FreeBSD.
What I would LIKE to do is:
1). Set my 10/100 nick as the dedicated outside/internet connection with a lan ip of 192.168.1.100
2). Set the gig nick as the dedicated... (2 Replies)

ipfw
IPFW(4) BSD Kernel Interfaces Manual IPFW(4)NAME
ipfw -- IP packet filter and traffic accounting
SYNOPSIS
To compile ipfw into the kernel, place the following option in the kernel configuration file:
options IPFIREWALL
Other kernel options related to ipfw which may also be useful are:
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPFIREWALL_FORWARD
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100
To load ipfw as a module at boot time, add the following line into the loader.conf(5) file:
ipfw_load="YES"
DESCRIPTION
The ipfw system facility allows filtering, redirecting, and other operations on IP packets travelling through network interfaces.
The default behavior of ipfw is to block all incoming and outgoing traffic. This behavior can be modified, to allow all traffic through the
ipfw firewall by default, by enabling the IPFIREWALL_DEFAULT_TO_ACCEPT kernel option. This option may be useful when configuring ipfw for
the first time. If the default ipfw behavior is to allow everything, it is easier to cope with firewall-tuning mistakes which may acciden-
tally block all traffic.
To enable logging of packets passing through ipfw, enable the IPFIREWALL_VERBOSE kernel option. The IPFIREWALL_VERBOSE_LIMIT option will
prevent syslogd(8) from flooding system logs or causing local Denial of Service. This option may be set to the number of packets which will
be logged on a per-entry basis before the entry is rate-limited.
Policy routing and transparent forwarding features of ipfw can be enabled by IPFIREWALL_FORWARD kernel option.
The user interface for ipfw is implemented by the ipfw(8) utility, so please refer to the ipfw(8) manpage for a complete description of the
ipfw capabilities and how to use it.
