I CANNOT HANDLE BEING CALLED OUT ON MY DUMBASS OPINIONS ABOUT ANTI-VIRUS AND SECURITY. I REALLY LIKE TO THINK THAT I KNOW THINGS HERE

INSTEAD I AM GOING TO WHINE ABOUT IT IN OTHER THREADS SO MY OPINION CAN FEEL VALIDATED IN AN ECHO CHAMBER I LIKE

OK, so I've got a dumb question/situation.

I have a client that's part of a commercial office building. We upgraded his network w/ an 8-port switch from a 5-port switch. It's at that time that I noticed the building's network is just wide open. I used an unmanaged switch in part because I assumed that wouldn't be the case, and because I didn't know any better. Quickly learned the difference when I got home and researched.

So, I want to swap it for them here so that I can setup a more secure network. I only want the Internet connectivity incoming and to push whatever through that so that their devices wouldn't show up on the building's network at large.

I wouldn't be able to affect anything but this switch, so no other modifications to the network would be available to me.

Would this be possible?

So, what is the upstream device that your client's switch runs to?

What is handling DHCP?

What types of devices are on your client's network? (i.e. PCs/laptops, servers etc)

Something that can send emails without needing an open SMTP relay or can only authenticate in plain text to Exchange. It's time that these MFP vendors did their scan-to-email and scan-to-sharepoint via an Azure AD app integration.

Our new kyocera’s have sharepoint integration but it was pretty annoying to get set up.

I mean, there is literally no reason to have to use a server component to send scans to a document library.

1. Not sure, likely another switch but setup w/o restrictions. The office suite has the one ethernet port that runs to the in-office switch. I would expect that the building's switch is handling DHCP due to the range of IPs I saw. (192.168.33.xxx) Also, a printer that appears to have been auto-discovered but not in the office.

2. A few PC's and 2 printers. But the data on the PC's is fairly sensitive, both are setup w/ BitLocker encryption as part of their company's requirement, so I'm trying to be relatively pro-active/secure.

The volume is relatively low, so we are talking table top in most cases, we only have a few free standing bigger devices and those are leased.

I literally wouldn't. Make them walk to the big free standing one.

If you absolutely have to, a lot of leasing companies offer leases for the table top ones, too. I would lease that, as well.

Yeah, it just means, when it breaks - who fixes it? Who order toner? If you can swing it, try to keep it all under a contract. Bonus points for keeping those contracts so they co-terminate when the other leases are up, that way you have one time every X number of years to renegotiate and aren't just perpetually stuck with overlapping contracts.

If you use exactly the same big MFP printer everywhere, you never need to worry about what needs what toner, what needs what toner waste container, what model you're talking to someone about, what drivers you need installed, what printer should be your default printer, etc. The additional technical debt added by a single printer of a different kind than your other printers is loving huge.

We got rid of our desktop printers when we moved headquarters four years ago, and it was the smartest loving poo poo we ever did. I would guess it cut total ticket volume by close to 20-25%.

Managed switches usually top out at layer 2. You won't really be able to do anything with a managed switch other than turn specific ports on and off, set port speeds if available, and assign ports to VLANs, but none of those things will really help with security in this scenario. What you need is a router, placed between the switch and the outside network. Outside network -> Router WAN port. Then connect Router LAN port -> Switch port 1. Connect everything else in the office to your 7 remaining switch ports and there you go. You'll need something to act as your DHCP server within your new office network, and you'll need to make sure to set the router's LAN port IP address as your default gateway handed out by your DHCP.

At that point your small office network should be isolated from the building's network.

Dumb question: Could you link a model that you’re thinking of? I’m guessing a router is a router is a router, so even a wireless router w wireless disabled would be of benefit. Although if that works, maybe I just swap out the switch and the router, hide the Wifi network, and have his laptop connect that way when he brings it in.

Let me know if I’m wildly off base. I tried poking around for wired routers but they don’t exist in the form I remember them in from 2005ish.

What's the safest tool to reach for non-appliance storage? I'm working with a university research lab who is keeping data on a couple 12x10TB RAID 6 arrays and several 4x12TB RAID 5 arrays with hardware RAID controllers. I believe around 250TB usable right now. They've been hand-managing cross-mounting directories via nfs so all data is accessible from all servers, and don't have dedicated "storage" or "compute" machines.

They want to put a parallel filesystem (lustre or similar) on top of this instead, but I'm kind of terrified for them trying to do a parallel filesystem on hardware RAID on heterogenous hardware, including arrays with only 1 parity drive. The biggest argument in favor of this is that when everything is up, it would be fast as hell for their workloads and the group has previous positive experience with GPFS at a previous university, which was apparently also just running on top of hardware RAID controllers and never broke in ~8 years.

A dream solution would need:
  • Not lose data
  • Expose a POSIX filesystem
  • Large file read speed significantly higher than a single 4x12TB RAID 5
  • Large file write speed at least comparable to a single 4x12TB RAID 5
  • Easy to add more storage in single-machine 4-24 disk increments
  • 1/3 or less disk space parity overhead

Data loss would be a disaster. Hardware failures can cause outages, but should not lose data. Filesystem-level compression would be nice to have, but they can just run stuff through gzip as they've been doing instead. I think that they can get high availability and would appreciate it, even though they say they don't want HA. They've got tons of CPU available (Xeon Platinums), so stuff like erasure coding would have as much CPU as it can use available. Everything is on Ubuntu 18.04 right now.

The migration plan is to get enough additional storage in one batch to comfortably hold everything they have now, set up whatever storage solution they move forward with, put all the data on there, and then wipe and add all of the existing machines to the storage pool.

So: The least bad option that I see is Gluster or their original plan of "just throw lustre on there". Ceph sure has a lot more whiz-bang features, but looks object focused, block second, and filesystem as a 3rd class citizen. Other stuff exists like LizardFS and MooseFS, but I'd feel safer with one of the Red Hat funded big boys.

All in all, beats the hell out of the last time I janitored computers for them, which was trying to figure out why software wouldn't build on their old-rear end SUSE on Opteron machines.... in 2017. :zombie:

If you have an end of life (Windows 2008) server that you're using as a fileserver whats the best way to go on replacing it? Would upgrading it to 2012, then 2016 even work?

Build a new server, add it to your DFS domain, set it up as a replica target of the old server. Once everything is replicated, set the new server as the primary and nuke the old one.

That would come close to "just working," but you will have to share out folders and if you have any permissions on the share itself instead of NTFS you'll need to do that. DFS-N/DFS-R or DFS-N w/o Robocopy isn't a bad path. Microsoft also makes a tool to help these days - https://docs.microsoft.com/en-us/windows-server/storage/storage-migration-service/migrate-data

Now would be a good time to look into using Azure File Sync w/ cloud tiering if you use Azure and/or think you would ever want to go that route.

When Azure File Sync added support for NTFS permissions we greatly expanded it's use. We only have a little under 1TB of files synced right now, but it is working well.

We did this and it worked great. There’s a registry key you can export/import that has the share info as well.

In our case we went from 2003 to 2016 and had no issues with this method.

I'd trade it all for just a little more.

Not sure if this is the place for this, but the home networking thread didn't seem right either.

I got a weird request. Small office has 2 distinct networks, a 10. and a 192. For reasons that are probably silly, they don't want to change ip configs, but want to share a copier. I used an extra port on 10dots firewall to connect to the 192 network switch, setup the routing on 192's firewall to provide a route back to to the copier, and pinged it + hit its configuration webpage from both networks. All seemed good.(at this point, I just did an allow all on the firewalls for testing).

When printing, the job will error out on the pc, and get stuck in the printer's job log for 10 minutes or so before printing a pcl error page(or a generic error if using a non-pcl driver). Also disabled the firewall on the client pcs just in case they were being weird about talk back from an ip outside their subnet.

Any ideas?

Does the PC print successfully on the 10. network?
Is the port connecting the 10. firewall and 192. switch a routed port or a switch port?
Do you still have the Allow All rules in place on the network firewalls?
What port(s) are used to connect to the printer?

yeah 10. works fine.
10. is a routed port, other end(into the 192) is a switch port.

I have sort of a very unofficial marketing question for IT pros.

When you are researching new tech for your office (say...privilege management solutions), what is your process and - primarily- your engagement with videos on possible solution's websites (Bomgar, Thycotic, CyberArk, etc).

Are videos and animated explainers helpful? Do you send them to your boss to help with purchasing decisions?
