Unhandled Exception:
System.NullReferenceException: Object reference not set to an instance of an object

What "the hell" i miss??

Problem that I mentioned post up is still not solved.

my server (install with php,mysql,etc.):

root@fragmiona:~/TT# mono hashtopus.exe
Hashtopus 0.8.5
Registering to server...Enter registration voucher:

--------------------------------------------------------------------------------
my client:
bash-4.2# mono hashtopus.exe

Both server & client are running Mono:

Server is Slackware 13.37, Client is Slackware 14.1.

md5sum hashtopus.exe at server:
912916fc01721eb4463a6342b3c7a79e

md5sum hashtopus.exe at client:
912916fc01721eb4463a6342b3c7a79e

It means the same binary file (hashtopus.exe) at server and client, same version of Mono, but on client it doesn't work correctly.

Is this a some kind of bug of hashtopus.exe, or am I forgot something to do???

Yes, I am from CZ.

As for your error, "at hashtopus.Program.diagnoseSystem () " means it's in the diagnoseSystem method. If you understand at least a little C-like languages, you could read through the agent source in this method. Obviously something can't be read on your system (it's listing GPUs from lspci, determining name of the machine and determining uuid for / partition - if not found, it will generate a random string)

I followed the manual, I don't understand what I'm doing wrong.

The exception should not happen. Please run the hashtopus.exe in a command prompt window so that the window doesn't close when the exception occurs. You can then send it here.

As for the error, you can clearly see ERROR: No hashes loaded.
This is a oclHashcat output and it's telling you that something is wrong with your hashlist
and that it couldn't find any hashes in it.

It's the same in a command prompt.

I uploaded a hash in hashtopus, why he can't find it?


RESOLVED, was a charset problem!

Hi curlyboi, I'm from SVK (your brother )). We can talk by private message later...

So, you right. My problem was that hashtopus.exe did not find correct uuid of my / partition.

blkid:
/dev/sda1: UUID="2c418eb4-ad6c-44ee-8085-79dc77559d7e" TYPE="swap"
/dev/sda5: UUID="199e1e41-6831-4b82-8fc3-8225c9d0d641" TYPE="ext4"
/dev/sda6: UUID="2770a48f-2794-443e-8198-59551f5db98c" TYPE="ext4"

/dev/sda5 is my "/" partition. In previous version of Slackware (13.37) blkid gave this reply:
/dev/root: UUID="30e0d5fb-6d6d-406a-813d-646b7844f728" TYPE="ext4"
/dev/sda1: UUID="1d076026-d562-4d3a-a29e-054005076545" TYPE="swap"

(I don't understand what is uuid (of "/" partition) good for hashtopus?)

Maybe you will update your hashtopus.exe to find the "/" uuid with /etc/blkid.tab or better use "blkid -o list" (thats got correct results)
Or is there any other solution to find uuid on linux systems?

Check file hashlist/1 in hashtopus directory. Does it look correct to you?

As for that error, it seems your HTTP server doesn't like something on the hashtopus request. Check server error log or try to capture that request with Wireshark to see whats happening.

The uuid server as unique agent identifier. Keeps dupes away of your agents.

Are you sure the blkid -o list is correct command to replace globaly? I dont have a linux box nearby. Can you explain what that command does?

Sorry I'm late...

From manual page:
blkid -> locate/print block device attributes
-o list -> print the devices in a user-friendly format


blkid -o list - I tried this on some kind of ditributions:
Slackware 13.37
Slackware 14.1
Fedora 14.0
Ubuntu 12.4
CentOS 6

These Linux distros gave me the same results:
root@bambusko:~# blkid -o list
device fs_type label mount point UUID
---------------------------------------------------------------------------------------------------------------------------
/dev/sda1 swap <swap> 2c418eb4-ad6c-44ee-8085-79dc77559d7e
/dev/sda5 ext4 / 199e1e41-6831-4b82-8fc3-8225c9d0d641
/dev/sda6 ext4 /home 2770a48f-2794-443e-8198-59551f5db98c

==============================================================
There is a one another solution how to correct this problem (my problem with hashtopus.exe 0.8.5 agent). Make link in /dev folder:
ln -s /dev/sda5 /dev/root (in my case)

Then blkid will give right results:
root@bambusko:~# blkid
/dev/sda1: UUID="2c418eb4-ad6c-44ee-8085-79dc77559d7e" TYPE="swap"
/dev/sda5: UUID="199e1e41-6831-4b82-8fc3-8225c9d0d641" TYPE="ext4"
/dev/sda6: UUID="2770a48f-2794-443e-8198-59551f5db98c" TYPE="ext4"
/dev/root: UUID="199e1e41-6831-4b82-8fc3-8225c9d0d641" TYPE="ext4"
