Question DHCP - for me, the user, what benefits?

Just exactly what do I (the desktop user) get out of it?

As above, you get to plug your computer into a network port and have it pick up all of it's network settings automagically rather than messing about filling in all the details yourself.

If you're talking about an office situation with static PC's you won't see much benefit as an end user, but if you're talking about your Broadband connection it makes the whole thing easier with less configuration for you to worry about.

Besides, things like this aren't to benefit the end user, they're to make my job easier

I really love it because my Xbox and my 360 both need static Ip's because of firewall rules. so I have to used DHCP then reserve a static ip on the router

I feel sorry for peeps who arn't into computers trying to setup home networks it really isn't all that easy at times

Sorry, this is from an office perspective....

.. where we have port security enabled, so you can't use your bloody laptop anywhere but at your own desk...

.. I can't see any benefit to me, infact the opposite, as I now have to look my IP everyday (they won't give me a static IP for some reason!?) so I can use eXceed...

Pah...

I think port security is to stop MAC address flooding/ hacker attacks.
Maybe your company has had a previous problem !!

Exactly... albeit a minor PITA, it's still a PITA!

Still keeps our Wintel/comms guys in a job I s'pose - wonder what it'll be next year...

Do you have to use the IP address for the DISPLAY thingey? Can't you just use your hostname/DNS name instead?

depends if the remote machine can lookup your desktop's 'name' .

Easier to tunnel it all through ssh tbh , spot of X forwarding and it's gravy , can get a little slow when you are getting a window back from machine X when you've tunnelled through A > B > C > X to get there though

Nope... doesn't appear to be defined in DNS.

Steve - yeah, just looking at SSH tunnelling now - not used it before.

Hey Alex, what you trying to break this time?

Port security is normally set on the switches and is locked down to mac addresses. Whatever ip you get is not affected by this, unless they go as far as ip based acl's

Exceed, bah, I use a NC900 XTerminal booting from a nfs share...

LOL - me.. nah.. nothing

Yeah I know the MAC address is what port security is based around - my point was that they've have this enabled, so I can't use a.n.other desk on a.n.other site - so 'what has DHCP ever done for me!'

NC900 eh.. nice

DHCP has given you an ip address so you can work

If you really, really, really, really want to work at another site, get the mac address for that port and spoof it Not sure if your internal IT would like that though

Have they never heard of hotdesks?

you just need to have control over the sshd_config on the remote box(es) , shouldn't be a problem for a man of your means

Very useful for installing & patching stuff like websphere and oracle , where the command line installers are flaky/non-existent.

Ah, we use VMPS so wherever you plug in your laptop, you'll get the same settings (and restrictions ) as if you were sat at your own desk. Equally, I could plug my laptop into your port and view pr0n without having to go through the proxy/web filter

BTW, that won't be DHCP restricting you, that'll be your Network Admin doing port security on the switches.

Yes - I know.. the same people that have forced us down the DHCP route..

I just find it amazing that something so flexible is implemented in such a useless manner... all it has done is made our network peeps life easier... well so they think...

Set your laptop IP to the same as one of your core servers, plug it into the right vlan, and keep doing that until they sort you out

**** that.. Spoof the MAC of the default gateway / core switches

What you need is a really really good reason of why you cant do part of your job with a dhcp assigned address then they have no choice

sounds like b!llsh!t to cover the fact they don't now how to - reservation is designed to account for those users that require a static ip but the company has a desire to implement DHCP - For security reasons I have a reserved IP for my mac address on the network card, so that if I connect wirelessly I do not get that IP, but I get one from the pool. Means I can only access certain places when I am hardwired - which is exactly what I wanted.

Unless you work at my place. Different sites, different subnets... We've pretty much run out of private ip's. Imagine the DHCP/DNS system

using just the 10.n.n.n rage provides 16581375 unique addresses , so that would be impressive....................
