I was using hydra without any issues until I decided to update it. Right now when I'm trying to run hydra I'm getting this error: > hydra: symbol lookup error: /lib/x86_64-linux-gnu/libmongoc-1.0.so.0: > undefined symbol: mongocrypt_kms_ctx_get_kms_provider I tried reinstalling both hydra and libmongoc-1.0 and trying to find something in terms of symlinks but with no luck. What is exactly going and and how can I prevent it/handle in the future and mostly how to fix it right now?

Using this documentation : 1. I've pulled the vimagick/hydra docker image 2. Created docker-compose.yml file in ~/Soft/docker/ folder: hydra: image: vimagick/hydra command: sleep infinity volumes: - ./data:/data working_dir: /data restart: unless-stopped 3. Installed docker-compose 4. Executed: `docker-compose up -d Starting docker_hydra_1 ... done` 5. Executed: `docker-compose exec hydra bash Error response from daemon: Container ecf710f3f9526cf598c4a15a485fbfc3790a36e5f8b989820a157ba5453fc24f is restarting, wait until the container is running` docker ps gives: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ecf710f3f952 vimagick/hydra "bash sleep infinity" 20 hours ago Restarting (126) 20 seconds ago docker_hydra_1 93b5c43c6952 vulnerables/web-dvwa "/main.sh" 39 hours ago Up 23 minutes 0.0.0.0:80->80/tcp dvwatest $ docker exec -it ecf bash Error response from daemon: Container ecf710f3f9526cf598c4a15a485fbfc3790a36e5f8b989820a157ba5453fc24f is restarting, wait until the container is running I see that docker-compose.yml file contains restart: unless-stopped record. But why is it documented so and how to use this container when I could not connect to it? Thank you!

I`m using **Hydra** with **Cygwin**. Can anyone help me with this error? When I using -x option, this error is shown: [ERROR] -x option is not available as math.h was not found at compile time my Cygwin consists recommended packages and even more than that (125MBs)

I'm running a Hydra on Rasppberry PI. There were some problems with the program, but aside from these, there is a hidden memory leak in the program. The source is pretty big and really can't find the problem. Unfortunatelly, upon reaching memory limit, the program doesn't crash - instead it returns bunch of error messages. When I say bunch, I mean hundreds. So I thought the if I can't un-allocate the memory within the program, I might need to reset whole process. **So I need to:** 1. Guard the process resource usage 2. Stop the process **gracefully** (similar to Ctrl+C, the program says "*received signal 2*" then) 3. Start the process again I must do this until fix the program to die on errors - or not to produce them in the first place. ---- If you know hydra and you're curious about the errors I've found at least something in the code:

[ERROR] Fork for children failed: Cannot allocate memory
[ERROR] socketpair creation failed: Too many open files

The second part of the errors comes from perror C system function. It's sort of last error.

I have SSHD running on port 5800 on some machine. (It is a my machine at home.) If I run this manually in a terminal: # ssh someIP -p 5800 The connection is lost because I am disconnected after 3 consecutive mistakes. OK. Now I do a brute force with hydra on this port with ssh as specified service and password root. It seems to run and tries passwords, but now I wonder why I am not disconnected this way. Is this because hydra instantiates a new connection for every new password, closes it after trying the password, and opens a new connection again for the next password attempt?
