I’ve managed to get myself completely stuck on the last part of the Privilege Escalation in the HTB Academy.
All signs point towards getting hold of the users id_rsa, copy and chmod, and then ssh in with the copied credentials. However when I do this I’m asked for a password and that’s as far as I can get.
I did notice something though, when I was doing a very similar task on TryHackMe, I copied over the contents of the id_rsa, and pasted them into a blank document via the file manager. When I saved the file, the icon changed to a key (which says to me that linux has recognised it as an ssh key), but when I do the same procedure in the HTB instance, it stays as a generic text file, suggesting that it’s not recognised as a key, and that would be why the password is still asked for.
I have absolutely no idea how to get round this issue, so any help would be appreciated!
After banging my head against a wall for weeks, I was watching one of John Hammond’s videos, and he made a point of mentioning that when copying id_rsa keys, you need to make sure that there is a blank line at the bottom, underneath where it says “End of Key”.
Thank you for this post MetalMonkey667. I’ve spent days trying to get past this. I’ve copied the id_rsa file to both nano and vim, and added and extra line at the end. In each case, when I try to ssh to user2 using the file, I get the error:
Load key “id_rsa”: invalid format
If I do anything else (eg pre adding the extra line), I get asked for a password for user2, which of course I don’t have.
It sounds so straightforward, but is there a specific way to add the extra line in vim so I don’t get the format error please?
I get the error message Load key “id_rsa”: invalid format when trying to connect to root with ssh user@spawn -i id_rsa.
I have tried to copy the private key content on a new files in my local machine using both vim and nano and same results.
Is anyone have an idea of why I get that result?
Hello, after several hours trying the same thing I ended up giving up because despite the help on the forums I can not connect as root with the ssh key, I am always asked for a password that I am obviously not, I followed to the letter all the comments on the forums nothing works would someone be in the same case as me please? sorry for my English is Google Translate
