I try to deploy ICP-CE env on single centos 7.3 server, the installation and setup is successful, ansible script not throw any error or warning.
But when I open ICP UI on browser and login by default admin user, the UI throw error "You are unauthorized to view this page.":
Does anyone can tell me why this happend, or how to troubleshooting?
Thanks.

I am getting ElasticsearchStatusWarning saying that the cluster state is yellow. Upon running the health check API, I see below
curl -X GET http://localhost:9200/_cluster/health/
{"cluster_name":"my-elasticsearch","status":"yellow","timed_out":false,"number_of_nodes":8,"number_of_data_nodes":3,"active_primary_shards":220,"active_shards":438,"relocating_shards":0,"initializing_shards":2,"unassigned_shards":0,"delayed_unassigned_shards":0,"number_of_pending_tasks":0,"number_of_in_flight_fetch":0,"task_max_waiting_in_queue_millis":0,"active_shards_percent_as_number":99.54545454545455}
initializing_shards is 2. So, I further run the below call
curl -X GET

Thing is I was earlier getting alerted for Unassigned Shards due to the same exception as above - "CircuitBreakingException[[parent] Data too large, data for [<transport_request>] would be [4322682690/4gb], which is larger than the limit of [4005632409/3.7gb]"
But back then heap was only 2G. I increased it to 4G. And now I am seeing same error, but this time with respect to Initialising shards instead of Unallocated shards.
How can I remediate this?
Application is in C, to read only NFC card details(card number & date). Following the steps below
CardRead("1PAY.SYS.DDF01", "PSE1");
Ex:APDU - (0x00, 0xA4, 0x04, 0x00, PSE1,00) or
CardRead("2PAY.SYS.DDF01", "PSE2");
Ex:APDU - (0x00, 0xA4, 0x04, 0x00, PSE2,00)

Please let me know how to frame next command PDOL/ReadRecord from the above data to read track1/track2 data.
Download EMV Book 3, read section 10.2 Read Application Data. It has it all. Find below in case you cant get the document.
I have two files:
file 1:
a1 45 1/1 895
a1 65 0/1 478
a1 80 1/1 474
a2 45 0/1 145
a3 50 1/1 415
a3 32 0/1 547
file 2:
a1 45 1/1 784
a1 65 0/1 454
a1 89 1/1 354
a1 105 0/1 365
a2 45 0/1 478
a2 65 0/1 985
a3 32 0/1 658
a3 65 0/1 985
I want to compare both columns of file 1 with file 2 and only if both match, then I want to print the whole line in file 1.
output:
a1 45 1/1 895
a1 65 0/1 478
a2 45 0/1 145
a3 32 0/1 547
This is the solution I am thinking about in awk:
awk 'FNR==NR{a[$1$2];next} (($1$2 in a))' file1 file2
I was wondering whether there are other ways of doing this in bash.
Thanks!
If full line needs to be matched then grep -f is simpler option:
grep -Ff file1 file2
a1 45
a1 65
a2 45
a3 32
EDIT:
awk 'FNR==NR{a[$1,$2];next} (($1,$2) in a)' file1 file2
a1 45 1/1 784
a1 65 0/1 454
a2 45 0/1 478
a3 32 0/1 658
I am completely new to Ruby, and I am having issues installing it on my Mac running Mountain Lion OS... any help would be great!!!
I have followed a tutorial, and I have installed GIT, curl and RVM. Next step is installing Ruby, which I tried but i got the following error
$ rvm install 1.9.2

Any idea of what am I doing wrong?
Thanks!
First, you'll need to install the Apple Developers Toolkit (XCode) from the Mac App Store (it's free)
Once that's installed, you'll need to install the CLI command line utilities by running:
xcode-select --install
Then try your install again, and it should work for you.
Additionally, you may want to install the latest version of Ruby, which at the time of this writing is 2.1.0 (via rvm install 2.1.0)
Finally, if you haven't already, I would recommend installing homebrew as well, as this has the added benefit of checking your runtime environment for errors (via brew doctor). You can find instructions here: http://brew.sh/
Good luck!
I have come across to similar problem

I install Xcode Command-Line Tools

Requirements installation failed with status: 1.
decision:
sudo apt-get update
delete the falling packages, and then run it again
look at the available packages
rvm list known
if necessary there is no. update package list
rvm get master
install the desired ruby
rvm install "ruby-2.5.1"
I got the same error - for me it was a problem with Homebrew - the last lines of the command logs said:
++ printf %b 'Failed to update Homebrew, follow instructions here:
https://github.com/Homebrew/homebrew/wiki/Common-Issues
and make sure `brew update` works before continuing.\n'
So then I ran brew update which then gave me another error message with instructions on how to fix it. After I followed brew's instructions I was able to install Ruby.
I am getting a strange output when I try to connect my ISO 14443a card to an NFC reader.

You can see that the cards is woken up, performs the anti-collision, then sends its ATS when requested (it gets asked twice for some reason?).
After this, the reader sends a strange command (marked above) and the card responds with an 'Operation not supported' response.
The wake-up, anti-collision protocol then restarts, and this goes on and on.
My question is, what does the command (c2 e0 b4) sent from the reader mean?
Thanks in advance.
I do not know if you are still interested in the response, I will just save time for anyone else who might be looking for the solution(like I was).
This is nothing else but S(Deselect) block sent from the reader, consisting of Protcol Contol Byte(PCB) and 2 bytes of CRC_A
C2 E0 B4
The same applies for anyone who might be looking for this command coming from the reader:
B2 67 C7
It is R(NACK) block, consisting of Protcol Contol Byte(PCB) and 2 bytes of CRC_A
They both are a fundamental part of ISO-DEP protocol(Type 4A or Type 4B tags), so read description and how to properly handle them in the "NFC Digital Protocol" spec, chapter "13 ISO-DEP Protocol"
