Oh yes it is integrated on the mainboard. Same things apply. If you know the motherboard model then again go to the manufacturers site. (Many have downloadable manuals that *should* have the chipset specs. Also most BIOS allow you disable on-board devices such as ethernet controllers. A...

If you have a look at the card you should see a model number from the manufacturer. Failing that look for the biggest chip and you might see a brand like RealTek or SMC or somesuch. This might be look like RTL8129. Type it in google and you might have luck in being able to download the driver...

Almost all ISPs will get these. All these show are that you are part of the internet. If your check the source address for these packets, you will find they come from all over the world. (On my ISP in Australia I get ICMPs and attempted TCP port 135 connections from lots of US based DSL ISPs and...

You want the MIB-II table ip.ipNetToMediaTable I have used perl SNMP module in the past, but you may find things easier if you use the NET-SNMP utilities (formerly UCD-SNMP). These are available for most platforms from http://www.net-snmp.org/ If you backtick the command `snmptable -Cf '|'...

Certainly host level security is important, whether data or voice. I am not saying that this should not be addressed, it's just that it is not a reason for not deploying VoIP. The fact that most of the exploits mentioned indicate that you already have a problem at the network boundary. If they...

SNMP is purely a means of remotely monitoring or controlling a agent. Normally this agent will have access to the "real" variables that are measured by or are used by the device. This real aspect could be anything, from the normal port level statistics on network switch, through to the...

As said, to implement VoIP you need to look at all the issues of cost savings, bandwidth/quality of service requirements, management etc. As far as the security issues, both the papers mentioned by pansophic appear to me to be scaremongering. All enterprise VoIP implementation run over...

Even better there are a lot of details on how to do this at http://net-snmp.sourceforge.net/tutorial/agent/index.html --------------------------------------- I'm just trying to help, and am not a spokesman for HP

Any private MIBS should be under the IANA managed tree at http://www.iana.org/assignments/enterprise-numbers To find the individial MIB from the vendor you will need to contact the vendor.

Linux uses "snmpd" as the agent. It makes available the standard MIB-II interface stats, etc. I would have a look at the code for this agent and work out how to push your real-world data into mib-variables. I believe a very common mechnanism is to use /proc to hold the data. How...

Unfortunately "channels" could mean a lot of things. Do you mean channels for PRI ISDN being used for Remote Access, or channels used for voice calls on Voice Trunk. You need to narrow down the particular subsystem you want to look at. I then do a "grep" of the MIBs...

SparkByte has some incorrect information here --> 1."On a network switch (not a Hub/Repeater) packets are not passed from one port to another "unless" that traffic is sent to a known network or device on that port.". In fact, if a switch (or a bridge) receives a frame with...

According to http://uwsg.iu.edu/hypermail/linux/net/0002.1/0047.html try changing /proc/sys/net/ipv4/ip_default_ttl

(If you have the "binary" config I found that using an editor and searching for the string "rwa" I found the password straight after it in plain-text. Else, here is a note from Nortel: Passport 1000 Password Recovery There is no known backdoor password for the...

Try using a "sniffer" and setup a capture filter for the source MAC address. (Try http://www.ethereal.com for a good Open Source one). You should see at least broadcasts from it. (If the machine is on the other side of a router you won't see it. But then MAC address are irrelevant if...

To specify the traffic that this policy is applied to you need to create also a class-map. This can use an access-list or an input interface as a classification criteria (among many others) Without any other options the applying this policy as &quot;service-policy output <name>&quot; it will...
