I am using a Super Micro motherboard model X11SPW-TF, which has a BMC and an IPMI interface. Using 'ipmitool lan print', I can get all network information, except 'link status' of the IPMI LAN-port.
How can I get that ??
Super Micro offers SMCIPMItool and this has support for 'SMCIPMItool lan linkStatus', but it only runs via LAN and not via /dev/ipmi0
Best regards

More than a question this may be general information . I am using a VPN service and located in the Middle East. I've found most (if not all but one) IP geolocation webpages shows my location as New York which matches the VPN IP address. But the service whatismyipaddres_dot_com shows the correct IP address and my location in Kuwait. Clicking some links on the mentioned webpage it takes me to a page showing they use several services from which one is showing Kuwait and the other two New York. However,contary on the expected "majority vote", they pick the single one different which, in fact, is right. As you can see they do not mention the name, but I believe the provider is Maxmind (maxmind_dot_com).
Sorry, not allowed to post images!!
Does anyone knows what they may be using ( router MAC? Google account ?).I use VPN to access ESPN , etc , but if this method is used by all other geoloc services in the future ,it will render the VPN unusable !
The web site whatismyipaddress dot com is using a mixture of HTML5 geolocation and IP geolocation.
Most likely your MAC address are being used to geolocate the location using HTML5 than using IP address geolocation.

I know in airports, for example, I've connected to their AP, and it pops up a browser window to log in on my device. Is it possible to do so with NodeMCU in lua, or even with c firmware?
This can accomplished by setting the DNS server for a connecting client [via DHCP] to a sort of DNS proxy. It doesn't need to be a fully featured DNS server, it only needs to be able to either return a static DNS answer for any host name query or forward the request to a real DNS server, to resolve host names as usual.
The static answer effectively hijacks web requests at the DNS level, by forging the DNS answer, causing all host names to resolve to the IP address of a local web server. That local web server ignores any Uri details and serves a login prompt for every request. It must also maintain a list of client MAC addresses that have authenticated.
NodeMCU does have a built-in DHCP server, as part of it's built-in WiFi AP, but running both a web and a DNS proxy in ESP8266's limited memory would be a hell of a trick. I think that two of them working cooperatively, interfaced using the SPI bus might be workable... maybe even three of them, one dedicated to maintaining the list of authenticated MACs, expiring them, etc.
Note that the only part of this I have done on an ESP 8266 is some very simple web server functionality, so it's mostly theory. If you try it I'd be very interested in hearing about it. :-)
You might want to try out CaptiveIntraweb project (https://github.com/reischle/CaptiveIntraweb) which is based on NodeMCU.
There is also thread (http://www.esp8266.com/viewtopic.php?f=32&t=3618) on ESP8266 community forum that discusses the solution details.
So here is my issue, I have a website hosted from a virtual machine on my server and am using a dyndns service to point a url to my IP. My ISP recently set up a new modem which unfortunately has its own built in gateway and router. After fighting it to forward port 80 I tested it by trying to navigate to the site via the URL and it didn't work, then I tested it on my phone connected to cell data network and it worked! I am able to visit the site via the URL as long as I am not connected to my network. i find this very weird and cannot figure out why.
I am able to view the site on my network by typing in the local IP of the server.
Any suggestions why this might be occurring?
Yes, this is a pain. Usually your modem won't route traffic from inside that's destined for its public IP address.
When you come from outside, the traffic hits the modem from the external line, and the port forwarding rules get applied, and the traffic reaches your web server. But those port forwarding rules don't get applied to internal traffic. You're trying to browse the web server on the modem, rather than on your server.
I did once find a modem that allowed forwarding of internal traffic, but that was a long time ago, and I haven't see one like it since. What I do these days is to use the internal address when I'm on the internal network, and the external address when I'm not. For things that get scripted, I have a little function that determines whether I'm on my local network or not, and programmatically chooses the right way to address the server.
This is because your router does not support hairpinning (or does not have it set up).
From Cisco Support Community:-
The term hairpinning comes from the fact that the traffic comes from one source into a router or similar devices, makes a U-turn and goes back the same way it came.
Visualize this and you see something that looks like a hairpin.
Hairpin NAT is a useful technique for accessing an internal server using a public IP. Since you are using a public IP to attempt to access a server in your network, the traffic will attempt to go out to the internet. In order to reach the server, the traffic will need to be redirected to the correct location.
The problem is how you are doing your internal routing DNS.
You can do DNS Lookup and trace route to see where the Website name is not resolving and whether if you ping the domain e.g. ping something.com return the public IP.
I resolved ours by doing policy routing on website FQDN to go through a different WAN. It's working fine. This works for those with different WAN terminating at the site.
The other way is redo the DNS configuration in internal network.
I have installed Plastic SCM server in one of my PCs at home (Windows 7 - Home Prem). The server is accessible from the clients residing inside my home network. It is resolved using the home network PC name as the server address / visible name.
However, I would like to be able to have access to the server from outside the home network. Ideally, I would like to use the IP that has been assigned to the PC, by the ISP, where the server resides. I can deal with the intermittent IP address changes. The PC is just a regular, personal use PC (i.e. not configured as a server).
A couple of questions: Is this possible to access Plastic SCM server from outside the home network using the IP address that the ISP assigns to the PC where PSCM-Server resides?
Second, the server config tool automatically displays as the visible name of the PC, the name assigned in the home network. It does not allow me to enter an IP address. If the answer to the first question is yes, how can I enter the desired IP address?
Are there any configurations that must be in place on Windows 7 (Home Premium), perhaps?
Any suggestions would be appreciated.
Plastic SCM servers listens in two ports: a SSL one and an plain TCP one. I'd strongly recommend you to set up an SSL connection if you're going to open up the port on the internet.

In order to configure your PC:
As you pointed you'll need to redirect the traffic from your router to your PC
The "redirection" must go from a public port to the Plastic SCM port (the TCP or the SSL ones)
Your PC should have the firewall configured to allow incoming traffic to the Plastic SCM port
Regarding your question about "the server configuration": no, it just shows you the name, you can't set the IP since it simply takes the IP/name from your server. It wouldn't work otherwise, unless you mean you've a multi-IP machine. Is that the case? Do you have more than one network card in your PC? If that's the case, there's a way to specify where to listen, but let's confirm first your scenario.
I'm making the assumption that you are using Plastic 4.x (I don't know how similar the 3.x version is to this)
The answer to your first question is YES. I frequently connect to my home plastic server from my work machine to view or grab projects/tools that I need.
Your second question is not technically accurate - what you need is the CLIENT tool to access your server IP address - and that IS possible.
To answer your final question - how to do it: start the Client Configuration tool on this "external" PC.
On the third page of the CLIENT configuration tool, it asks for the Plasti SCM server selection - it gives you an entry for the server address, and an entry for the port.
You most likely have set up the username/password access type on the server, but you could also have used Local users - be sure to select the appropriate log-in type you configured your server for on the final page.
Your only other consideration is the Firewall on Win7 (and as pointed out by Pablo, your router config to 'point' to your server machine on the desired ports (8087/8088) need to be forwarded) must allow those ports to be accessed. (I believe 3.x used different ports)
I'm developing rails(2.3.8) application. I need to store actual client's remote IP address.
request.remote_ip returns only 127.0.0.1
but I need to store actual remote IP such as 93.43.56.77. Any ruby gems is available? or how do get that?
Try this:
request.env['REMOTE_ADDR']
If your request is coming from your development machine and the development machine is where your server is, probably you will get 127.0.0.1. But if the request is coming from another machine, this will be the IP the remote machine. However, under various conditions this may not be the real IP of the machine (machine behind proxy, using tor or other tool to hide it e.t.c.).
Your computer essentially has two network interfaces.
'93.43.56.77' which is for your network adapter which connects to the network via wireless or wire.
'127.0.0.1' which is a virtual adapter which is used when connecting to itself.
You will not get the application to show '93.43.56.77' unless the connection is running over that connection, which means it will need to be on a different computer.
If you are so concerned about it, you can easily push it up to Heroku where it should work as you expect.
