Hello, freelancers, I was changing some stuff on my AWS CentOS, just changing some folder permission in one of the websites. But for mistake I have ran this: chmod -R 755 / Yes: I have change system permission files to 755 permission. Now i cannot even connect to the machine to see what can be done. Putty do not even connect, it returns "Network error: Software caused connection abort". My SysAdmin is out, and I cannot fix it alone. And I need an experienced SysAdmin to help me ASAP on that. If you read untill now, please post "What a mess, brow", otherwise I will not take your bid in consideration. Thanks!

Hi There Here's how I will approach to solve the problem. 1. Create an EBS image of the existing EC2 2. Create a new EC2 instance and attach to this newly created EC2. 3. Mount this EBS Image as read mode only. 4. Then I will go through the kernel init logs and goes through stacktrace to find the fault and take appropriate measure to solve the same. Besides I'm an AWS expert and currently ranked no 1 in freelancer for AWS category. Checkout my previous AWS projects at https://www.freelancer.com/u/joystick220.html Thanks Joy

What a mess, brow It's because some system users lost write permission to some dev/system files since now only root can write places where other users are expected write access as well. You need entire OS Permissions restored, what centos version is it? We can get on it right away, 75/h will take between 1 to 3 hours depending on amount of data on the server.

What a mess, brow ==================== I am Shijo V Jose; a Linux server administrator having more than two years of experience. During my career as a server administrator I've worked in a hosting support company and hence I've worked with a number of hosting companies to provide support to their respective customers. I have better and keen experience in shared hosting, VPS hosting and dedicated hosting environments. Among the popular control panels, I have my expertise in cPanel and Plesk. To be a successful server administrator I believe both technical and customer handling skills is mandatory and I assure you both of these. And time zone is not a problem for a hard-working admin like me. During my present profile I face different kinds of issues and this makes me more powerful and experienced.

What a mess brow. Dear sir, I read your project description. I am sure I can do this for you, in a timely manner. Please take a look at my profile, here is my skillset as well as more informations about me. https://www.freelancer.com/u/thms00.html You are basically gutted. You need a sane CentOS (similar setup) system, dump permissions and then restore them all through rescuse system. I have all the commands ready.. just need a sane CentOS setup (should be easy since you are using amazon cloud) and then restore all perms for SSH to work again. This will be a starting point. Then we need to check perms on all files thare not on the fresh install once we gained SSH access and main OS functions back to work. Please come and have a PM chat with me, I am kind and helpful. I will also add you on Skype once the project is finished so if you have any problems I'll be there, I am a full time Freelancer. Willing to start right-away! Regards,

Hello, I believe this should be recoverable. I will need console access to the server through AWS, which will require access to your account. From there we can attempt logging on as if connected through hardware and look into attempting to restore permissions and allow remote connections again. If it's not possible to login via console, this could still be done by rebooting the instance into a live environment via an iso. The permissions could then be fixed from there. Thanks, Andrew DUQUETTE

hey .. seems like you have put urself in a stupid position .. "What a mess bro !" (wrote it just because u put that in there haha) but don't worry .. this is fixable.. You need to learn a few commands to reset the permission on all the files. so first of all you need to gain access to the server .. I am not sure how this would work .. but there would be a control panel where you can directly connect to the server. Now the learning part: you need to reset permissions on all the rpms installed within your system. now here is the command to do that sudo rpm --setperms {packagename} you need to run above command for all the packages installed in the system following command would list all the packages installed in centos rpm -qa --- happy hacking .. hope this helps .. let me know if you need my assistance in this further.
