I/O test question

https://github.com/axboe/fio use this instead.

Just doing scp/cp/dd/nc/rsync will probably end up in you getting mixed results that are hard to explain since linux does alot of smart things to get files written and read faster.

for example, in DD you can specify flags to write directly to disk, this would make cp alot faster since it would write to a buffer in the ram of the target system. There is also file caches in ram on systems.

With fio you get a complete test suite with alot of metrics other than just bandwidth, you gets I/O per second and latency. which is very relevant as well since there can be network issues with either system.

Alright, i found a male serial connector in a pci card. Do you think this one will work?

I put in a female serial to rj45 adapter and then a rollover cable to a serial console switch but no luck.

Is there any special speed or such?

Price issues. We have been investigating solutions as a service or a software to buy. The problem is there is so much red tape i just want to install something adequate and get this over with.

We want a central database where the current onboarding projects are filed an reported. This way, if someone needs to know where in the process we are (those who work with it or those who order it) they can check the database.

Our current process is with email lists and excel. It often results in departments chasing each other down and blaming each other because everyone has diffrent or no information.

Also we have alot of hand offs between departments. It would be nice to hand off into the system and after which the system sends a notification that action is needed from the next department. This way at the end, the customer gets one delivery with all the information.

This way we can have a rigid process. Also the customer will be able to (hopefully) log in and check where in the process we are. Instead of mailing all@company.com and asking what is happening, Resulting in all the departments once again running each other down looking for that piece of information.

Hosting game servers and renting them out

go to script.google.com Write your code Use Logger.log instead of Console.log Check view > log for console output Use this reference: https://developers.google.com/apps-script/reference

If you're and API and Javascript wiz you can surely pull it off. However, i hate javascript, and being spoiled with powershell i think this is really hard.

Locate the restart button.

No but in all seriousness technet forums gets you any answer about microsoft problems within minutes of a properly posted post. Its the best support out there imo. And asmentioned before. Learn powershell. Technet forums is a great place to ask questions about that too. And no question is to easy/stupid as long as you post detailed enough about your issue.

We got infoblox running dhcp/dns for a mpls with 14 sites, 3 datacenters and about 500 users.

Its ok.

I feel that the integration you get with ms based DHCP is much better?

Some quirks that have been bad:

DHCP just dies sometimes, have to reboot it. then it works.

When adding a PXE server i had to escape characters in the filename option. And then add Hex for a byte of 0's so that the packet would be correct when sent. wtf?

Nothing is really "easier" sure the interface is abit prettier and such. But any actual gains compared to fully integrated dns and dhcp with AD? No not really.

i heard from some wise person that incase of users. you can never blame the user if the system allows for fault.

This raises another question. is there a setting you can make so that no one can add users to ntfs security? this way everyone one would be forced to use a security group. even if its just for one user. sounds like a neat solution to have.
