I am trying to install OpenCPU inside a docker container. After some steps, this message appears:
I am quite new to Linux because I am a Windows user. I found nothing on my research so I am asking this question.
Can I just choose some random mail here? Thanks in advance.

I stuck in a problem, I want to shutdown the Linux PC using system command but my machine is asking to enter the password.
here is the scenario: I'm using 2 systems one is windows and another one is Linux. I'll send the command to Linux for shutdown, this Linux PC application made it as Service file, once I receive the command for shutdown, My Linux PC run the system function which is written like this system("shutdown -P now"); if I run this command my machine won't execute the command.
Kindly help me out in this!
Thanks & Regards
thank you Some programmer dude for your valuable feedback. Posting your suggestion as answer to help other community members.
The shutdown command needs super-user privileges. You can use some
additional commands to elevate the privileges along with the command
you are currently using.
could anybody help to understand me how is it possible verify and validate server's hardware configuration that I'm going to install into datacenter? The problem is that the customer bought noname server and we need validate that configuration of it correspond to spec (validate) and make sure that all components into it are working (verify).
This is first problem. The second is that servers will be hundreds...
Sorry for the question, but I'm novice into this area so I'll be thankful for any help.
A little more details: all servers are x86-base, into the future the customer will install Linux on its.
You can use hwinfo utility for linux system for machine hardware information.
I am new to linux OS. According to the requirement of my project I have to install extensible Hypervisor Framework( XMHF) and then build the required hypapp over it. Grub is supposed to load the XMHF at boot time and then the ubuntu OS has to laod over it, But when i am trying to boot the system according to the steps mentioned to install XMHF the system stops at the Starting up.... state at the time of booting. I dont know where i have done mistake. I have checked it many times but nothing useful. Can anyone please help me with this?? "Installing XMHF" manual can be found at http://xmhf.sourceforge.net/doc/xmhf/doc/installing-xmhf.md.html
My grub entry for XMHF is
title XMHF
rootnoverify (hd0,0) // as i have no primary partition for the hard drive
kernel /boot/init-x86.bin
module /boot/hypervisor.bin.gz
modulenounzip (hd0)+1
I had the exact same problem.
I had to properly configure serial output, either physically or serial-over-lan, to see XMHF's output. In my case, I missed a Intel VT related switch in BIOS.
How to configure serial console can be found here: https://www.cyberciti.biz/faq/linux-serial-console-howto/
go through this http://xmhf.sourceforge.net/doc/xmhf/doc/installing-xmhf.md.html this will be helpful :D
I have Ubuntu 10.04, 10.10, and 11.10 in virtual machines on oracles virtual box that I am testing products on. The licenses for the software to run is on my machine which is assigned a static IP.
SO what I have done for all the other Linux distributions I have done testing with is assign the .bashrc file a line in the end like this: export LICENCE=27065#192.168.1.45 causing it to look in the network for my machine to check out and check in its licenses. I have done the same with Ubuntu but cant get it to work at all! So far Ubuntu seems to be the only one with this problem.
SO i figured that maybe it was a connectivity issue. perhaps some behind the scenes security factor that i didn't know about. Well turns out I can ping my machine on the network just fine which makes me a little more lost.
Any info on this or even some more troubleshooting tips would be greatly appreciated.
Is this a FlexLM license? It looks like it because of the port#hostname string.
LICENCE looks wrong, these products usually use LM_LICENSE_FILE or *$PRODUCTNAME*_LICENSE_FILE, see eg. http://opendtect.org/lic/endusermanual/chap12.htm
Check with telnet if this host/port is available: telnet 192.168.1.45 27065. It's possible that ping works but connecting to this specific port doesn't.
Depending on how you start the shell in, .bashrc is not used, do you see it when you echo the variable? If not, stick it in .bash_profile instead
Try setting FLEXLM_DIAGNOSTICS=3 as described in the link above.
I have an old computer with formatted drive lying around collecting dust, now I want to instal a linux like OS (any suggestions?) on it and install a web server, preferrably Lighttpd. I want to set up a server so that I have an environment to practice web development in PHP or Java. My problem is I dont want to hook up another set of keyboard/mouse/monitor to that old computer, and if possible I want to remote boot/shutdown the server from this computer that I use to type this question.
I did some google search, but the results are never comprehensive or suitable for my circumstance. Any input would be appreciated, book recommendation or link to a good resource are fine too.
Thanks
Qin
P.S. I did some search on stackoverflow before asking this question, if there is another similiar question being asked, let me know.
You actually needs an unattended (silent) linux installation, which may trigger beeps to tell you when the installation is done. Hope this can help you refine your search on google.
You'll definitely need at least a monitor or KVM and a keyboard if you want to install any OS on it.
For server OS, you could try going for CentOS / Ubuntu. However, if your requirement is just to practice your PHP and Java, you could even use your existing laptop / PC and, assuming windows, you can just install wamp or xampp, to install your apache/php/mysql with just clicks.
