Nothing work for me, on Ubuntu 12.04.5 LTS !

[s4miii]

Hey bro,
first of all thank you so much because of your great job,
actually I installed it on Ubuntu/Linaro 4.6.3-1ubuntu5, the progress done without any error, even my Apache and SSH service restarted , but nothing work, like I do nothing !?

Am I miss something ? I do as your wizard, any idea?
and is there any video or youtube link for the installation ? maybe I done something wrong ?
thanks a lot.

ld.so.preload either truly does not exist, or a deeper kernel space hook is intercepting open()

Actually I want to connect to my server remotely, how is it possible ? because ssh won't work and even I tried via netcat too, for example this is your ssh script :
./ssh.sh my-user 127.0.0.1 5342

the output is :

my-user @127.0.0.1's password: 
Permission denied, please try again.
my-user @127.0.0.1's password: 
Permission denied, please try again.
my-user @127.0.0.1's password: 

nothing work actually !

Are you able to connect to the server via ssh as a regular user? Or is permission denied all round?
In reference to the output you posted, nothing there relates to why you can't log in. I should remove those arrays on the repo though...
Ubuntu 12.04.5 LTS also provided some security changes from previous releases... The Ubuntu documentation for 12.04.5 LTS is... minimal. (lol)
Execute the following commands and post the output as a reply please. Replace 'CHANGE_ME' with the name of the environment variable created/used during the vlany installation script. Make sure you're also root before executing this, since if vlany is installed, the environment variable does nothing until you're root.
Alter ls/grep below if you changed the default installation settings.
CHANGE_ME=1 sh -c 'cat /proc/self/maps; ls /lib/ | grep "libc"'
If vlany is actually installed, the library path and address space should show up in /proc/self/maps, but of course it would usually be hidden. Not to forget that libcrypt (and libssl if ssl was enabled) will also show up. Please show me full output.

Thanks for your reply, yes I always connect to this Server via SSH, but with vlany, just showing Permission denied, and also I'm root !

Maybe if you remove the line about homo...., Your script will be work 😅

alright, the output as you want is :

Doesn't seem like vlany is installed, properly.
Try echo /lib/libc.so.sysinfo.25/full_name_of_lib.so.x86_64 > /etc/ld.so.preload and see if you can log into the backdoor user via ssh.
Also start a new bash shell and show PAYUCFCZOALI=1 sh -c 'cat /proc/self/maps; ls /lib/ | grep "libc"' output again after echoing the lib path into ld.so.preload.

[s4miii]

when I done this :
echo /lib/libc.so.sysinfo.25/full_name_of_lib.so.x86_64 > /etc/ld.so.preload
And opened new bash shell, it shows me :

After that I again tiring to connect via ssh and it won't work :

Permission denied, please try again.

and the out of this command :

[mempodippy]

Using the environment variable, look in /lib/libc.so.sysinfo.25/ for the full name of the library, and put that where 'full_name_of_lib' is. It's always randomized, so I don't know what yours will be.

[s4miii]

YtBG48AqRvST.so.x86_64
YtBG48AqRvST.so.i686

[mempodippy]

Yes. Put that into ld.so.preload, and show me the results. Try connecting to the ssh backdoor user.

[s4miii]

won't work, it's shows again
Permission denied, please try again.

so I removed the /lib/libc.so.sysinfo.25 via chattr, and re-install vlany, in this time SSH shows this :

groups: cannot find name for group ID 239939463
ls: reading directory /etc/bash_completion.d: Operation not permitted
su: Cannot determine your user name.

[s4miii]

for uninstall the previous version, removing /lib/libc.so.sysinfo.25 is enough ?
and would you please give me an example about the connection via netcat ?
because it's won't work either :(

[s4miii]

Hi, any idea about this error ?

groups: cannot find name for group ID 239939463
ls: reading directory /etc/bash_completion.d: Operation not permitted
su: Cannot determine your user name.

when I wanna connect via SSH it shows me this error

[mempodippy]

Do not remove the installation directory. Ever. Shit will go down. This will cause the dynamic linker to throw a fit, and in more real scenarios, the dynamic linker isn't going to be using /etc/ld.so.preload, so you'd have to hunt for what file the dynamic linker now uses. Recompiling vlany is enough to reinstall, but I've not released anything to automatize the process of uninstalling (properly)/installing new versions. So this needs to be done manually.
The accept backdoor is deprecated. Look at the netcat help output.
Additionally, that's a common error. The severity of it varies though.

[s4miii]

Alright, thank you for your reply, actually I tested vlany on the other server, and again it shows this :

ls: reading directory /etc/bash_completion.d: Operation not permitted
su: Cannot determine your user name.
Connection to x.x.x.x closed.

normally I connect to via SSH, but with vlany I can't.

This Server is :

Distributor ID:	Debian
Description:	Debian GNU/Linux 6.0.10 (squeeze)
Release:	6.0.10
Codename:	squeeze

any idea?

[s4miii]

Sometimes there isn't any /boot/grub/grub.cfg or /etc/grub.conf or any type of grub.conf is there anyway to fix this issue ?
thnx
