comment How to check nginx open file limit on Ubuntu Server?
@BadrHari You're changing the limits set by PAM when the user logs in, but the user never logs in. So what you're doing doesn't make any sense. You need to look at how nginx is started on your platform and how nginx itself is configured.

comment Handling the potential risk of writing random bits to storage during power loss with RAID
This just expands the window in which we're vulnerable to a failure. Consider two writes where we're screwed if one is completed by not the other. With the extra seeks required, the window between when the first one finishes and when the second one starts will be longer. So we're worse off.

comment Is “Peering” in networking, always exchanged directly?
@HBruijn I think he meant settlement-free peering. Sure, it still makes sense to peer with asymmetric traffic with settlements. (Or in the rare case where asymmetric traffic exists without asymmetric cost, but that's very rare. Generally, outbound traffic is much cheaper than inbound traffic.)

@Semphie94 They can't peer with each other without a connection to peer over, and someone has to pay the costs of that connection.

How would a small, local ISP in Washington peer with a small, local ISP in Copenhagen? And if they found some way to do it, how could they possibly exchange enough traffic to justify the cost?

comment Ping don't resolve www.domain.gob.sv but it does resolve domain.gob.sv on server
If www.domain.com is a CNAME for domain.com, that means they have the same records. So if ns1.domain.com is a nameserver for domain.com, it must also be one for www.domain.com. But if you must setup a zone for www.domain.com if it's a CNAME for domain.com, what good does the CNAME do you? You could set up a zone without a CNAME. So if you need the CNAME, it's insufficient, and if you don't need it, why have it? Your configuration doesn't make any sense.

comment Can I use a server adapter card for GigE cameras on an industrial PC?
The whole point of GigE cameras is that it's easy to interface many of them because the interface bandwidth is much higher than the camera needs. Can you tell us the make and model camera you're talking about?

What SSDs do you plan to use? And how much of their space do you expect to use?

comment Can't Bind IP Address To Machine
@kasperd Yes, exactly. Those errors indicate he's trying to do something that's already been done. The only question he's asked is why he's getting those errors, so that's why I answered it.

It depends what there is. Read the man pages for commands like ip.

When it says "File exists", it's because the specific thing you are creating already exist. If you down all the interfaces and remove all the IPs and routes, you won't get those errors.

Changes to what? The only question you've asked references specific errors that I've already explained. We honestly don't know what you're asking because we've answered the only question you've asked.

@sugarisgood What problem? You still get precisely the same errors? Because that's the only problem you've mentioned.

Then I guess I don't know what your question is. You might want to edit the question so that people can find out exactly what you want explained or what help you need.

comment How can I access a URL through it's IP address?
David and Jeff may have the same phone number, but getting David on the phone and getting Jeff on the phone still result in you talking to a different person. You connect to the same phone endpoint, but what happens after you connect is different.
