kandi X-RAY | alcor Summary

alcor is a Java library typically used in Architecture, Microservice applications. alcor has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Cloud computing means scale and on-demand resource provisioning. As more enterprise customers migrate their on premise workloads to the cloud, the user base of a cloud provider could grow at a rate of 10X in just a few years. This will require a cloud virtual networking system with a more scalable and extensible design. As a part of the community effort, Alcor is an open-source cloud native platform that provides high availability, high performance, and large scale virtual networking control plane and management plane at a high resource provisioning rate. Alcor leverages the latest SDN and container technologies as well as an advanced distributed system design to support deployment, configuration and scale-out of millions of VM and containers. It is built based on a distributed micro-services architecture with a uniform way to secure, connect, and monitor control plane micro-services, and fine-grained control of service-to-service communication including load balancing, retries, failovers, and rate limits. Alcor also offers a way to unify VM and container networking management, and ensures ultra-low latency and high throughput due to its application aware fast path when provisioning containers and serverless applications. The following diagram illustrates the high-level architecture of Alcor control plane.

Dropdown Menu Table Call Requires Extra Click After Selection with JQuery DataTables

Asked 2020-Aug-12 at 13:26

I have a list of dropdown items, that when selected should bring up a table connected to the value. When using this jquery code to call the table, I select the first dropdown, then select the second dropdown (which is used for the value of the table id). However, once I select the second dropdown, the table does not coming up. In order for the table to show up, I have to click the second dropdown again, then click off, and then it will show. Any suggestions for what I'm doing wrong here?

Here are selection options

Actually, you can do it without jQuery DataTable, you can do it with a regular table.

Take a look at my example:

QUESTION

Error loading PKCS keystore with multiple card readers

Asked 2020-Mar-23 at 01:46

I am running into a weird problem when reading CAC card, in a multi terminal setup, from Nth (Except 1st) terminal.

Environment - JDK8_u211, Destop without any card reader, Internal card reader for laptop, USB card reader, CAC\PIV card

USE-CASE Tried

When the CAC card is plugged into internal slot of Laptop, everything works fine with and withou USB card terminal connected to laptop.
When the CAC card is plugged into the USB reader and connected to the Desktop, everything works fine.
When the CAC card is plugged into the USB reader and connected to the Laptop, the PKCS store instantiation fails, as the config uses slot=1
When the CAC card is plugged into the USB reader and connected to the Laptop, if I hard code slot=4 in the config, everything works fine.

Problem: Unable to determine the correct slot to use within the config file. Somehow number of terminals is not adding up to determine the slot at runtime.

By enabling JDK debug logs, i could verify that internally "C_GetSlotList" returns 0,4 where as I have only 2 terminals, hence using index 0 or 1.

Does anyone know how to determine the correlation between terminal vs slot or is there something really wrong in the way i am trying to read the card ?

Please advise.

You are getting confused between slot id and slot index. They are two different attributes.

The C_GetSlotList gives you an array of slot id's not slot indexes. In your case 0 and 4 are slot id's, not slot indexes. The slot index is the index of the slot id in the array.

In your getSmartCardTerminal() method where you are identifying the terminalIdx you are identifying the index, but in your registerProvider(Integer idx) method you are mapping the index as the id, here:

OPENSC_PKCS11_DLL + "\n slot = " + idx + " "

When you are using the slot index you should be using slotListIndex and when you are using the slot id, you should be using slot.

So to fix your problem change it to:

OPENSC_PKCS11_DLL + "\n slotListIndex = " + idx + " "

Invalid IP address in add-host: "" + Failed to program FILTER chain: iptables failed

Asked 2019-Feb-02 at 10:47

I am working with a scientific code which was packaged in Docker containers by another person. I am not very familiar with all the magic behind containers, images etc. And I was using it only by running some simple commands like docker-compose up or docker-compose up --build if I needed to add some dependencies in the code.
So everything was perfectly normal until last night. I was running a simulation that took a whole night, but I saw that results were not ok, so I just killed the processed by pressing ctrl + C 2 or 3 times. When I tried to launch simulation again by docker-compose up I got an error which, unfortunately, I can't recall right now. Also, strange thing - at that moment I couldn't connect to Internet. I rebooted, Internet worked fine again, I tried to run docker-compose up again and I got the following output:

How to add a device with VID/PID in Linux

Asked 2018-Nov-04 at 16:08

I am working on a smartcard project in Linux, and I am using Alcor 9563 smartcard reader, I use ccid/pcsc , but Linux doesn't identify the reader:

How can I add this device with vid/pid in Linux?

ANSWER

Answered 2018-Jul-25 at 18:42

https://ccid.apdu.fr/ is the homepage of libccid. It has a list of supported readers. I didn't find your reader. It also has detailed instruction how to test if a reader is supported and how to contact the developers.

The Vendor ID looks interesting, it is not the one usually used by Alcor, and it is not known to the USB ID repository https://usb-ids.gowdy.us/read/UD?restrict=2

Java Card returning 6F00 while installing applet

Asked 2018-May-17 at 08:02

I have a J3H081, SCP 02, T=1, GP 2.2.1, JC 3.0.4 java card and want to install applets onto it.

Unfortunately I get on every *.cap file I tryed error 6F00 (Command aborted - more exact diagnosis not possible (e.g., operating system error)).

I tried the pre-compiled *.cap from here: https://github.com/LedgerHQ/ledger-u2f-javacard, built it myself with JavaCard v3.0.3 SDK, from AppletPlayground I tried the OpenPGPApplet and YkneoOath. All result in an 6F00 error while installing.

The only applet I was able to install was the pre-compiled AlgTest_v1.7.4_jc222.

Because you probably don't have the features necessary for those applets and applet initialization throws an exception which is not handled. This specific case seems to be no support for ECC.
