Is there a way to see the update deadline times for updates in WSUS? In the Updates view I can only see if an update has a deadline or not, not the actual time.
This is the deadline time you can set for updates to force them to install by that time.
Is there a way to estimate how much space I would save by compressing a folder with NTFS compression without actually compressing the folder?
This is on a Windows 2008 R2 server in case that makes a difference.
We have a Dell Poweredge server running ESXi 4.1 U1 that was installed using Dell's customized ESXi ISO. Now we would like to upgrade to 4.1 U2 and upgrade any Dell specific bits that were installed.
I downloaded the 4.1 U2 Dell Customized ISO and tried to install over the existing installation but it doesn't look like I can do that non-destructively.
I tried upgrading using VMware's Update Manager, and that upgrades the ESXi installation, but I don't think it upgrades the Dell specific bits.
It sounds like Cicso's virtual tunnel interfaces let you run dynamic routing protocols over IPSEC tunnels without GRE (see here). I was wondering if there was an equivalent in Juniper's JUNOS. I didn't see anything in JUNOS' documentation but I'm hoping someone here has used it and knows the same of the feature.
What is the difference between active and passive FTP?
note: I think this would be useful as a community wiki question. Also, I'm hoping someone can come up with a clear concise answer like this question: How does IPv4 Subnetting Work?
We have a 3U Supermicro chassis with 16 bays on a SAS expander backplane. We have 15 of the bays occupied with hard drives at the moment. We would like to add two more drives to the backplane, but we only have 1 bay open.
Does anyone know if there is a way to “add” more SAS ports to our backplane?
EDIT: More details!
We have this motherboard which comes with an onboard SAS HBA: http://www.supermicro.com/products/motherboard/QPI/5500/X8DT6-F.cfm
inside this chassis: http://www.supermicro.com/products/chassis/3U/836/SC836E16-R1200.cfm
I'm pretty sure this server uses the same chassis: http://www.pogolinux.com/quotes/editsys?sys_id=163850
If you go through the configuration page for that server, you can add 16 HDs + 2 SAS SSDs. That means they're filling up all of the bays and connecting 2 SAS drives internally. The chassis comes with brackets to hold the SSDs but I don't know where they would plug into the motherboard or the backplane. The motherboard SAS connectors are both plugged into the backplane.
There's a lot of documentation out there on how to create an Exchange 2010 DAG, but not much on how to revert back to a single server. Has anyone ever done this successfully?
I've recently been in a situation where an Exchange email server went down and we weren't able to bring it back online after 48hrs, so some incoming emails bounced. Also, users weren't able to send or receive emails for a few days, which was a sore point and caused some early withdrawl symptoms.
In a post-mortum someone came up with the idea of setting up a quick and dirty webmail server to catch those emails during the outage so that at the very least people could receive and send emails. I've never done this, but it sounds like a good idea. Has anyone tried something like this before successfully?
We have a vSphere cluster of 4 ESXi servers licensed for Standard. We want to purchase some Advanced licenses so that we can use the Fault Tolerance feature in vSphere, but we don't want to upgrade the entire cluster to Advanced if we don't have to (it's ridiculously expensive).
Does anyone know if you can run Advanced features on just a few specific servers in a vSphere cluster without having to upgrade the entire cluster?
We currently host all of our clients in one datacenter. We would like to expand to two new datacenters by the end of the year. My job is to figure out how to extend our current network to those two locations.
I have some basic designs drawn up (site to site VPNs between the datacenters, OSPF for internal routing, round-robin DNS to distribute the load), but I could really use some advice from someone who has done this before. My major concern is making a design choice that will constrain us or require a redesign in the future. We already have some design choices that will hamper us in the future (e.g. every client gets their own 10.x.x.x/24 subnet with their own VLAN, which will work great right up until our 4093rd client).
Does anyone know some good resources on how to create a scalable network design?
EDIT: Our business resembles VPS hosting, so as you can imagine, there's all types of traffic. Most of it is web (80,443) and mail though, so throughput is the usual priority followed by latency.
The business reason we want to expand is so our clients can host their servers either on the East/West Coast US or South Pacific Asia. The IT reason is to give us a disaster recovery site in case of natural disaster.
EDIT 2: Just to be clear I'm looking for resources on how to design the network. The details on how to do it (VPNs, routing, DNS, etc.) I can do.
We have a new office that was punched down with Ethernet in every office and every cubicle. The electrician didn't mark the ports on the patch panel or the wall ports, so I don't know where say port 1 on the patch panel goes in the office.
I've heard of people using a tone generator to figure out where the cables are but I'm not sure what that entails. I was also thinking of looking up ARP entries on our switches to find out what port is getting what MAC address and then cross referencing it with a list of MAC addresses on all of the PCs in the office. This sounds unreliable though.
Is there a quick and easy way to label these ports?
I ordered some new PCs with Intel vPro enabled on them, but now that I have them I'm not sure how to use it.
I found some old websites about using Altiris and Microsoft SMS but those are expensive and really meant for large organizations. Does anyone know of a free or cheap way to use vPro?
Our company just switched to a new email domain and wants to keep the old domain around for a year as they notify everyone about the change. The old email domain was on Exchange 2007 and the new email domain is on Google Apps. Everyone is 100% on Google Apps, and the Exchange server just forwards on emails.
I would like to replace the Exchange server (it's underpowered and a waste of resources just forwarding emails) with something lightweight, based around Postfix or another email server. It needs to do the following:
- Forward emails sent to old_domain.com to new_domain.com
- Autoreply to the sender that everyone's email has changed to new_domain.com
Is this possible with Postfix, and does anyone have documentation on how to do it? I know just enough Linux to be dangerous, so I want to be sure before I suggest this.
Do I need the Backup Exec 2010 VMware Agent plus the Exchange Agent to backup an Exchange VM? Or will the VMware Agent take care of it (minus any granular recovery features; we're looking for disaster recovery options only at the moment)?
(It shouldn't be this hard to figure out an answer to this from Symantec's docs, but I can't get a straight answer)
We have a 2 node Exchange 2010 server setup with a DAG. I really didn't want to use Public Folders, but we need them for a legacy app. I created two public folder databases, one on each node because you can't make PF databases part of the DAG. They replicate to each other. Right now, I have one of the PF databases selected in the DAG as the default public folder database. It doesn't look like you can select a failover.
My question is: Is there any way to load balance across these two PF databases? Or if I can't do that, can I set them up to failover automatically if one goes down? It looks like right now I can only have one PF database on one node in use at a time, and if that node goes down, public folders go down as well.
We have a Windows 2008 server that we want to move offsite to the cloud (we're using Rackspace). It has to talk to our Active Directory domain constantly, so we need a stable site-to-site VPN between it and our datacenter. Rackspace doesn't offer a virtual VPN device, and a quick search shows that Cisco-Windows VPN tunnels don't work well, if it all. We do have a Windows 2008 server in our datacenter that the offsite server could connect to.
What is the best way to get these two Windows 2008 servers to connect to each other?
We are going to let one of our sysadmins go in a few weeks. He has access to our entire infrastructure, so we'll have to reset the passwords on everything. This is going to be really time consuming though, with the number of servers and devices out there we would have to reset. A few things are tied into Windows domains so that's easy enough, but problematic depending on whether any services run as that user.
Is there any way to easily revoke access to everything for that user? I guess I'm asking for cross platform single sign-on...maybe RADIUS can do this? Or is there a turnkey solution out there like RSA SecureID? What have you guys used?
We have a lot of servers (running Windows and Ubuntu) along with a mix of Cisco and Juniper routers with a side of HP Procurve switches. We have a few sysadmins who like to make changes to configs without telling anyone or documenting it anywhere. You can imagine how this can blow up in your face.
Is there any software out there that can log and audit configuration changes in Windows, Linux, and Cisco devices? Or if there's no software, maybe some policies that can effectively stop this sort of behavior?
We have a Windows 2008 VM running IIS and SQL Server Express (it's an all-in-one web application). We need to have another copy at our secondary datacenter site.
What is the best way to do this? It doesn't have to be running all the time but it has to have almost the latest copy of the current VM. I took a look at VMWare Fault Tolerance and after the heart attack at the price I starting looking for another solution.
If need be I wouldn't mind copying it over to a cloud VM provider, if I can find one that lets me copy my own VMs up and start them up without any conversion process.
We have two buildings that are across the street from each other. Each has their own separate network. We needed to connect them together using a fast connection because of the large number of files that are copied between the networks on a daily basis. We have a wireless bridge setup right now between the buildings that gives us about 20Mbps (it's two Aironet 1240AG in root/non-root configuration).
Unfortunately there's a lot of RF interference in the area (lots of residential buildings) and the Aironet's lose connectivity on a daily basis (which leads to a lot of disgruntled users). I'm thinking about upgrading to some Motorola PTP wireless bridges but I wanted to ask, am I going about this the right way? We went with the wireless bridges because it was cheaper than getting a hard line between the two buildings but I'm starting to regret that idea given how badly these AP's are working. Any suggestions?
Edit: The Aironet's are using the 5Ghz band and use 802.11a. The antennas are directional panel antennas.
