I have simple script:

Current Server Version: 0.11.0
Current Client Version: see below
Hashcat Version: 5.1.0

I would like to build the client for the arm architecture.

Following instructions on the Frequent Problems page, I cloned the source from github.
I  list my difficulties and questions below.

1. "you need to download the sources, build it with make"
The source has no Makefile, so how am I supposed to build it?
Edit: I have built it with build.sh  , but the resulting zip still gives me the same Exec format error.
Same  architecture mis-match resulted.

2. "add it to the hashcat 7z archive"
Please, explain what this archive is and how I may add to it.

3. "This archive should then be hosted somewhere for the clients to download and this url must be configured for the cracker binary."
Must it be hosted somewhere? If so, why?
Why must the url be configured for the cracker binary?
Please, explain what "configured for the cracker binary" means,

I am eager to apply hashtopolis to my arm computers. I would be most grateful for your assistance.

I presume not by sorcery.

But seriously. What is the mechanism by which the agent software stirs  hashcat to life and keeps it running?

Am I supposed to start hashcat somehow and it stays alive?

I do not understand my role, if any, with hashcat once the agent software is in effect.

Please, explain.

May Superhashlists be processed as one hashlist?

How do they relate to Tasks?

My objective, aside from a better understanding of hashtopolis, is to process a superhashlist as if it were one hashlist.

Is this possible?

Edit:
Upon re-reading the server manual, I see under Tasks,
"Hashlist Name of the (super)hashlist the task is cracking."

But,  when I try to create a new task, all I see in the pull-down menu are the original hashes.
How may I use my superhashlist to create a new task?

Hashtopolis has generated several vouchers, yet all of them it rejects as invalid.

No token found! Please enter a voucher to register your agent:

What do I need to do to allow hashtopolis to recognize its own vouchers?

I did not realize that vouchers were not in the box, but to the left, with the word Vouchers.

Sorry 'bout that.

I am using the latest, cloned hashtopolis server.

I have uploaded both rules and a hashlist.

As a test, I uploaded a small file as a wordlist, but I need this large, ~100MB one.

Hashtopolis seems to comply with my request to upload it, but in the end, the wordlist is not uploaded.

1. What may I try to remedy this issue.

2. Also, it would be more convenient for me to sftp the wordlist to the server. Is there any way to do so and tell hashtopolis that the wordlist is indeed a wordlist?

After typing this post, I realized that the problem had to be with apache. That triggered a memory that I had something in my notes (drawn from  your wiki). I copy it below.

You may want to increase these PHP parameters to accommodate your intended usage.

Ubuntu server-x86_64-16.10 > client Ubuntu 16.04 LTS

I tried extracting the python client in Client/home directory, import a new agent, & run all commands from there without "sudo". I tried giving the cracker binaries the https://hashcat.net/files/hashcat-5.0.0.7z download link with confirmed internet access (http"s" is OK, right ?). I tried an example from this forum where the cracker binary is suggested to be copied to eg: /home/user or maybe /var/www/hashtopolis/files & also */import. I also tried the files/import function to ensure it got to the right directory, each time confirming & changing cracker binary download url (eg; http://<server-ip-address>/home/user. Where applicable I set the binaries to "not locked" & allowed the client access to "locked or secure" files. Rebooted.
Still no hashcat download, extract & run.
Still having issues at this point, so did a new install, & allowed all privileges on hashtopolis server config as in an older video, hit the "go" button & confirmed settings were saved. I confirmed the suggested changes from server-prerequisites wiki were made & saved correctly. I set the /etc/apache2/apache2.conf <Directory /var/www> line to "AllowOverride All" I notice that there are some .htaccess files in directories that might be critical, that are still set to "Deny:all" on the 2nd line.
Am I supposed to change these manually ? & in which directories ? syntax as in apache2.conf ?
I guessed the allowoverride was supposed to do that, but the apache2 docs I found online seem to suggest that .htaccess overrides apache2.conf settings. Confused.

### STUCK HERE over 5 mins multiple times ###

used this :
"action":"getTask","response":"SUCCESS","taskId":2,"attackcmd":"-a3 #HL# ?l?l?l?l?s?l?l?l?l?d?d?d hash-test123"

& "taskId":1 without "hash-test123" included in command line.
I tried 2 ways, both times confirming the actual hashlist was part of the Task further down the page > "files":["hash-test123".
Also with the md5 hashlist added to command line from files/other as shown above.
Incorrect I think, but gettiing desperate.
Is this a hardware issue ? eg; only works on a proper server MoBo etc ?
Running server from an lga775 socket MoBo.

Thanks for support so far.
Any help appreciated.

Do administrators have nginx build tutorials
Do not know how to configure.htaccess

Ngnix .htaccess How to configure 
Is there any Ngnix build tutorial

Will you consider adding custom mask lengths later?
--increment --increment-min=1 --increment-max=9
Adding strings to New Preconfigured Tasks is a long task
