Server Administration - Science topic

I have been trying to download some Landsat 8 images for the past year. however whenever I add the mad to my cart and start the download, I always get this error

The server encountered an internal error or misconfiguration and could not complete your request.

Please contact the server administrator at edcweb@usgs.gov to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

may I kindly have a work around for this?

I try to run an overnight simulation but the job kept getting aborted due to error "session has been idle longer than 3600 seconds, disconnecting from Abaqus License Manager". How do i increase the idle time out so i can run an overnight job simulation without the job getting aborted?

How can I show that a Server can receive a ticket containing attributes of a user needed to release some services to the user, decrypts the ticket, then maliciously shares the attributes but the other servers receiving these attributes would not be able to use the received attributes again (i.e the attributes are useless.or invalid)?

Some time ago I used the Wolfram Lightweight Grid Manager to set up Mathematica for parallel computing in my local network. All the computers had installed Mathematica which have been configured to use the license server. This environment worked properly.

I have question if it is possible to configure Mathematica (which  possesses the site licence) to work similar to the previously described (but without the Wolfram Lightweight Grid Manager and the license sever). I think about the following situation. One computer is the master and the other (which working together in LAN) share their computing kernels.

Recently, I am using the Forcite module implemented in Materials Studio, but every time I run with the remote server, it fails immediately.

The remote server is CentOS7.0 with Intel E5 v3 2697. I have installed MS in the server, and I run from the Windows in my workstation.

But if I run that by using the worksstation, it goes well and succeeds.

Once run in parallel in remote linux server, the job fails.

I have checked the file 'std.err', it said this:

      "sh: error while loading shared libraries: libdl.so.2: cannot open shared          object file: No such file or directory"

So I locate the libdl.so.2 in CentOS7, it exist in /usr/lib:

     /usr/lib/libdl.so.2

     /usr/lib64/libdl.so.2

and

             lrwxrwxrwx. 1 root root 13 May 8 2015 libdl.so.2 -> libdl-2.17.so

I have googled this error, still don‘t know how to fix this bug.

I hope someone can give me a hand here.

We are using Jenkins as our CI system. Currently there is only one master server , with slaves provisioned from open-stack using puppet and foreman for configuration management. If for some reason our Jenkins master goes down , or gets deleted , or something like that , we need to provision a new machine and pull Jenkins master configuration from puppet ( plus copying Jenkins home directory from backup ) , the whole process needs more than one hour.  Is there any high availability setup for Jenkins master , active/active or active/passive? so that if one master goes down , the second one will automatically takeover without disturbing any build jobs.?

Dear All,

I have several Servers and I have downloaded all files from all servers.

sometimes, one of servers doesn't work properly and the ETL is unable to download files from the faulty server. So, ETL stops and it must be run manually again.

I would like to add intelligence to it so that it skips the faulty server without crashing. Do you have any idea How can I set my ETL to check the server's status. If I know the server status, I can skip it if faulty. For example, if server 3 has a problem, my ETL will be able to jump from 2 to 4 for download files instead of crashing at server 3.

Can anybody help me that how to catch errors and exceptions and show meaningful messages.Thanks

In MVC application, to prevent cross-site request forgery attack AntiForgeryToken is used. On each page refresh, new token is generated. But interesting thing is, if we duplicate the same web page in multiple tab in same browser(i.e each page will have same token value inside the form) and submit the form from all opened tab one by one, all the HTTP POST will be successful. This mean, the server is still validating the HTTP POST request even after the token value is already consumed.

How can I perform server consolidation using bin packing?

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. null null

I read many blogs and tried everything like

checking server name port number

changing my.ini file

changing timeouts

but nothing is working .

I need to get access to TFS build properties so that I can use it in my automated deploy build project.

Hello guys

I want to create my own SIP Server which will interact with "Open IMS Bench"  as a traffic generator in order to test a registration protocol.

Can you suggest me what is the best tool to create a such a SIP Server? If any ne suggest an other better generator ; it is really very welcome

N.B: My SIP Server should interact with a database (My SQL)

Many thanks!

Suppose we have a set of API hosted on a local server. I only want legal remote programs to invoke those APIs. If the remote program is, let's say the original program that I uploaded to the remote machine, then I allow the invoke. If the remote program is a version tampered by the attacker, then I disallow it. How can I bind the program's identity to the function invocation to determine whether the remote program is not tampered?

Is this possible with Libvirt or there exists some other means?

NOTE: This can be done within the Guests themselves but the interest here is to get the stat externally at the host. I have seen an approach for KVM but haven't seen anything for XEN servers.

I have little knowledge about the server consolidation tools but I am not very skilled so I need to know the open source tools available.
