Instead of having a bunch of VMs connect directly to an external SMTP server to send emails, I'd like to set up a local SMTP relay. So VMs will all connect to the relay and then the relay will connect to the external SMTP server.
What software should I be looking at? Postfix? It will run on linux of course.
People are not identical so they can't fit in the same chair - unless it can be adjusted to fit everyone. So any ergonomic chair with as many adjustments as possible would fit the bill. It will likely be expensive but good. I'm guessing the budget will dictate what you pick - more than your actual needs.

Microsoft of course knows they will sell more OS as more people will need to get new computers.
Isn't that the opposite? People don't pay for the OS, it's essentially a loss to MS on new hardware. And pissing people off at a time when a huge percentage of new computers aren't MS (Apple and Chromebooks are huge market shares on currently purchased machines) seems utterly foolish. Because triggering people to want to try out another ecosystem is a bad idea because trust me, no one uses Windows once they are comfortable with an alternative.
Forcing people to get new computers forces them to evaluate their OS choice instead of allowing them to just stay with it.
I mean Microsoft sell the OS to the PC manufacturers. So when people need new hardware they will get Windows because Dell, HP, etc put it there. The consumer is of course paying for it but indirectly.
And even if you install something else on it, Microsoft have already received their cut..
We're looking to organize our development projects and one option for us is Zoho Sprints.
Anybody here that have any experience with it or heard anything about it from actual users?
I've looked at it but would like to hear some opinions from users. Can't find much about it but maybe I'm looking in the wrong place.
Zoho have some good applications but also a couple that are so-so and just not worth the time.

Not impressed. Have to replace my CPU (Ryzen 5 1600) if I want to upgrade.
Yeah yeah, TPM blah blah blah. Still not happy about it. I've only had the CPU for 3 years.Granted I don't have to move until 2025 (WIN10 EOL) if I want to retain my hardware that long.
Just irritated that I can't upgrade straight away.These requirements may not seem too strict, but having a look at the list of supported processors, you’ll notice that the 1st Gen AMD Ryzen CPUs aren’t supported, and the 2nd Gen Zen+ processors are a bare minimum on AMD’s end and the 8th Gen Kaby Lake-R is the least supported on Intel’s end. Keep in mind that although the OS will run on systems using older processors, it’s “not recommended”. Microsoft’s list of supported processors doesn’t make sense as there’s little to no difference between the 1st and 2nd Gen Ryzen processors. Similarly, the Kaby Lake-R (8th Gen Intel Core lineup) is essentially a rebranding of the 7th Gen offerings.

It's called planned obsolescence. It's not done for any technical reason whatsoever, so looking for what makes "sense" doesn't make sense.
@voip_n00b said in Proxmox VE 7.0 Released:
It's our pleasure to announce the stable version 7.0 of Proxmox Virtual Environment. It's based on the great Debian 11 "Bullseye" and comes with a 5.11 kernel, QEMU 6.0, LXC 4.0, OpenZFS 2.0.4. and countless enhancements and bugfixes.
Here is a selection of the highlights
- Debian 11 "Bullseye", but using a newer Linux kernel 5.11
- LXC 4.0, QEMU 6.0, OpenZFS 2.0.4
- Ceph Pacific 16.2 as new default; Ceph Octopus 15.2 remains supported.
- Btrfs storage technology with subvolume snapshots, built-in RAID, and self-healing via checksumming for data and metadata.
- New ‘Repositories’ Panel for easy management of the package repositories with the GUI.
- Single Sign-On (SSO) with OpenID Connect
- QEMU 6.0 with ‘io_uring’, a clean-up option for un-referenced VM disks
- LXC 4.0 has full support for cgroups2
- Reworked Proxmox installer environment
- ACME standalone plugin with improved support for dual-stacked (IPv4 and IPv6) environments
- ifupdown2 as default for new installations
- chrony as the default NTP daemon
- and many more enhancements, bugfixes, etc.
As always, we have included countless bugfixes and improvements on many places; see the release notes for all details.
This is the kind of thing that prevents me from running Proxmox.
Debian 11, aka Bullseye, isn't the stable release of Debian. It's the testing distro for Debian. Later this year it's expected to become the new stable - when all serious bugs are ironed out.
Also Proxmox isn't running the Debian kernel. It's the Ubuntu kernel with patches. Why this Frankenstein mix of components? It doesn't inspire confidence.
@gjacobse said in Mobile interpreter station:
There has to be a better way to do this - better than what is in place now.
Components:
- iPad with application
- external BT Speaker
- Anker dual USB A for power
- Five wheel post stand
This is used when / as needed for the Interpreter(s) when someone comes in for those with little or no English skills.
The stand seems janky, and using an iPad with external Bluetooth speaker just seems like points of multiple failures. Not to mention there are power issues, you need a battery bank with pass through charging so that it will all work.
While this is a medical environment, no O2 is used that I have seen,....
There are plenty of medical rolling stands around. Even some that have dedicated tablet holders that are much more sturdy than what you have currently.
Otherwise, Android devices come in a lot of different form factors. Including those that have built in vesa mount, wired ethernet, PoE and management options. For instance Philips D-line or multi-touch series screens.
If you put that on a rolling stand you have better mounting options and can go bigger as well.
It also good to know that it is quite easy to have a custom bracket manufactured that you can mount your stuff to. Stainless steel would be best for your environment.

@pete-s how does any of this make my sense at all??? Did anyone even read any of this thread before posting???
You say he CANT use 16gb sticks which he has CLEARLY done already and have worked but instead of giving good answers you guys pressure people to move on because the people commenting on here either can’t read or don’t know enough already...
This is aggravating because every post about the T410 gets cut off with nonsense like this crp...
He used 16gb sticks so remove your comment, or don’t make one and move on if you didn’t have the answer to the question you just made the question more confusing
If you read more carefully next time, you might not become aggravated. What is supported and what works are two different things.
Reason to move on from old hardware is because for companies IT is a business, not a hobby. Spending time on something costs money, so the potential benefit has to outweigh the cost.

I'm not up to speed on HPs server options but 8-12 drives in a 2U server shouldn't be a problem.
He might need spindles for IOPs reasons.
But then, I'd look at SSD at RAID 5 (Scott has articles that explain the math on this and why it's safe) and you're crush your IOPs needs and likely be able to stay in a single chassis.
SSD cache is an option here too.
People tend to forget that high capacity drives are faster than lower capacity drives, due to their much higher data density.
@jim9500 said in 45TB-60TB / 45-60 mil file volume recommendations?:
Hope I'm not out of line to create two topics. I have DL360 G8 / 3 D2600s / 36 3TB HP MB3000FBUCN HDs / Raid 10ADM / Windows Server 2012 that hosts about 30 mil files used by 10-12 people daily. As jobs are processed, these files are moved off the server into cold storage.
I need to increase our storage to 45-60TB. My plan was to just migrate to Raid 10 instead of Raid 10 ADM (I haven't lost a 3TB drive since moving off of raid 60 to Raid 10ADM in 3 years). I'm a little alarmed after a recent file corruption issue described here - https://mangolassi.it/topic/23278/file-corruption-on-copy-issue
I've been a hardcore HP fanboy because I've had very very few problems with their stuff even buying used. Their continued aggressiveness at putting drivers behind paywalls + proprietary HD cost has me bent out of shape pretty hard. I'm looking at two possible solutions.
1 - Switch from Raid 10ADM -> Raid 10 / 30TB -> 45TB. Upgrade DL360 Gen8 to Windows Server 2019 (possible new Windows versions make NTFS volume of this size safer?)
2 - Switch to NAS / Exablox - StorageCraft type solution (I know this used to be shilled pretty hard - is it still top notch set & forget type solution? Will speed be comparable to 36 spindles on Raid 10?)
*I currently have a backup solution using VEEAM + DL380 w 12 drives + tapes for offline storage.
Option 3. New server hardware and no external SAS boxes. 8 x 16TB drives in RAID 10.
I'm not up to speed on HPs server options but 8-12 drives in a 2U server shouldn't be a problem.
This is the type of work that is easiest accomplish with a vector graphics design software.
A free open source solution easily available would be LibreOffice/OpenOffice Draw.
You could save the result in whatever format you want - pdf, tiff, png, jpeg etc.
@jimmy9008 said in Vagrant/DHCP problem:
Hi folks,
Long post...
So, we have a DevOps colleague who has setup automation with Vagrant to one of our Hyper-V hosts. I am not familiar Vagrant at all, but the allows his code to build VMs on one of our Hyper-V hosts. I am trying to rule out DHCP being the issue.
Most of the time the VMs are made successfully and get a DHCP address. Every once in a while, one of the automated VM fail to get a DHCP IP (well, they actually don't). (from being generated new)
We setup Wireshark to capture traffic for one of these failed events. When this fails I can see:
1 - the broadcast from the mac of the VM asking for any DHCP servers on the subnet
2 - the DHCP offer with the MAC of the client and the IP available
3 - the actual DHCP request from the client MAC with the IP which is available from step 2
4 - the DHCP Ack from the DHCP server confirming allocation completeI have checked the DHCP server and can see the record. Correct IP, MAC, and a machine name. Now, at this point I believe the entire flow has been successful. Now, this is where it goes wrong.
I connect to his VM in Hyper-V and login with the password he gave and type ipconfig /all
I get no IP, no subnet, but I do see DHCP = Yes, Gateway and DNS servers. I now type 'hostname', and the hostname is different to what is in DHCP!What I suspect:
- Vagrant makes the machine, it boots, gets an IP and is written to DHCP
- At some point, the code written gets the VM to change its host name and the VM reboots
- The VM (with its new name) asks DHCP server for the same IP
- DHCP server refuses as the hostname does not match the IP in its records
- Vagrant VM is left in a stage having no IP
Does this sound reasonable? I assumed if this were the case though that the DHCP server would send a NACK or something refusing the IP renewal/request, but do not see the traffic in Wireshark.
If I restart the VM or do ipconfig /renew, it does get the correct IP, and DHCP updates with the new name of the machine.
This once in a while happens to his Linux VM and his Windows Server VM which are made via Vagrant, leading me to believe the issue is Vagrant.The fact DHCP has a record of the IP, Name and MAC of the host before name change makes me think the issue is with Vagrant/his code rather than DHCP server.
Cheers
You might be confused by the hostname without it being a problem.
Normally it's the DHCP client that tells the server it's hostname in the DHCPREQUEST package.
So the hostname is set in the OS during installation and it's communicated to the DHCP server. The DHCP server stores this information in it's lease table. The hostname and IP can then be communicated from the DHCP server to DNS as well.
But it's also possible for the DHCP client to change the OS hostname based on a hostname the DHCP server sends - usually when having static DHCP reservations.
It's however not a requirement for the dhcp client to sends its hostname to the dhcp server and it's not a requirement that the dhcp client changes the hostname based on the hostname the DHCP server provided either. These are options that can be enabled or not.
Whatever the setup is, you can have the hostname inside the VM and the hostname on DHCP/DNS be different without anything being wrong.
I think you're on the right track using wireshark to figure out what is happening. I would have a close look on the MAC addresses to see what VM is doing what.
I don't know Vagrant but I don't see any reason for the DHCP server to supply a hostname to the VM when Vagrant is perfectly capable of setting the VMs hostname itself.
I would have a look at the DHCP server settings. Are you for instance using static reservations and are you setting hostnames from the DHCP server?

Sorry. I wrote a lot. The DHCP server is not controlling the hostname of the client VM in any way.
What I meant was vagrant creates a VM with a vNIC, and a hostname called say 'vagrant-123', it boots, gets DHCP successfully, talks to the vagrant server/control/source (I'm not sure how that works). That orchestration 'thing' rolls out whatever is needed to the VM, then changes its name to say 'DevEnv15'.
Changing its host name makes it reboot. At that point, it sometimes no longer has its DHCP address. DHCP lists the original name.Upon ipconfig renew, the VM gets its IP back.
Okay. Well, if you have a standard dhcp server and are not using static reservations, then the hostname has no influence on dhcp. It's the MAC address that determines what IP you are given.
If you want to check for the same VM doing several attempts at dhcp you should look for the same MAC address in wireshark. It highly unlikely that Vagrant changes the mac address after the VM has been created.

What ever happened to just sending a company wide "Thanks Karen" emails?
Why does a project like this even exist?
Kudos are a big part of many companies, and it's not hard to imagine why. Many companies will actually pay some bonuses or gift cards for kudos. A $50 visa gift card is an investment well spent when you have someone busting their ass. I have been on the kudos side and when you get a small token of thanks beyond a "Karen" email it means alot.
Sure, but sending out a Kudos through some specific application has nothing to do with the reward aspect that you're discussing, and wasn't at all a part of what I was discussing in my post that you opt'd to downvote.
This is specifically the delivery of an announcement, email has a very good delivery record. Why use something else for the announcement?
Someone from HR or wherever will still deliver the reward in person for that employee busting their ass.
The reason for kudos is because the companies are after enhancing employee engagement. They do it by instant gratification, recognition, awards, likes etc.
Think of it as a game. When you break the high score you'd want everyone to know.
That's why you see badges, awards and gamification in every kind of service nowadays. This is the same thing.
That's why just sending an email manually doesn't give you the maximum employee engagement. So that's a reason to look for something more elaborate.
@dashrender said in POTS EOL?:
uh - whats IP? VOIP is IP, does it really matter if you have an ATA in the picture?
Hell, yes it matters. Alarm systems may dial the central with DTMF tones but when they start communicating it's a totally different ballgame.
If voip could transfer all the analog audio signals exactly as they appear without any jitter or compression then it would work flawlessly. But that is not how voip works. To save bandwidth voip compresses the shit out of the audio signal. If the receiving modem can understand what the sender is saying then it work, but if it's too garbled the receiving end can't understand and it won't work. That's why it might work sometimes and sometimes not.
@dashrender said in POTS EOL?:
@jt1001001 said in POTS EOL?:
@pmoncho @Dashrender We are in the same boat with fax and alarm systems; in addition to having to support legacy PBX systems that can only be managed by dial-up. Several of our POTS have been moved to fiber delivered "voip" and off the carrier's copper plants but we have a few holdout ones that we have to pursue alternatives.
Like I just mentioned to @pmoncho you could look into SIP carrier like @Skyetel and ATA's to provide analog dialtone.
Only thing to keep in mind when doing this is that when you have no power, the alarm system goes on battery backup and it still has to still be able to dial out.
So you need to UPS the voip infrastructure so it will work for as many hours as the alarm system can.
I'm not an alarms guy but I think it's safe to say that best practice is to use GSM or IP and not analog->voip. It could be good to now that even the oldest alarm systems can be connected over GSM through something called a GSM communicator/speech dailer.
Also alarm systems can usually be upgraded by upgrading the control panel, which is the electronics that keep track of all the sensors. The sensors and wiring to them would be left intact.

@dave247 said in best way to map various combinations of mapped drives to AD users?:
Problem: we have about 10 different shared folders as mapped drives and a handful of simple bat scripts used as AD logon scripts for users...
I think it would make more sense to just have one mapped drive and use sub directories for each department. That's probably how the files are organized anyway - at least judging from the looks of it.
The users that have permissions to a particular directory can use it and the other can't. That way you don't have to mess with the different drive mappings because everyone get the same one drive.
This also also how I have seen organizations with many departments do it. They basically use one drive mapping per entire file server. Everyone has gets the same shared drive(s) but permissions determine what directories they can access. It's more flexible to do it like that.
Yes actually that's one plan I've had for a long time, just haven't gotten around to doing it mainly since it will disrupt everyone's workflow for a bit.
If you have the directory structure in place, you could do it by adding the new drive share for all departments. Give people a couple of weeks to start using it and then slowly start to remove the older shares one by one. That will force everyone to migrate to using the new share - but not everyone at the same time.

You could even go below $500 ea. Which would put you under $1000 for the entire array.
There are several enterprise drives in that price segment.

@beta said in RAID 6 in my backup VM host on spinning rust?:
@dustinb3403 Well I looked up Dell drives and the 3.84 SATA read-intensive drives are going for ~$1800 a piece (before any discounting).
Sounds about right. You pay 2x to 3x as much buying SSDs from Dell compared to the same drive from the manufacturer.
But you can get Dell drives from retailers as well for lower prices. Another option is to buy Dell refurbished drives with warranty.
@phlipelder said in RAID 6 in my backup VM host on spinning rust?:
Nah, in my mind KISS applies here.
Add the drives, expand the array, and call it a day.
Might not be so simple. Not every perc controller / version can grow a RAID10 array.
I believe the entire array needs to be restriped when doing that.
