Is it possible to somehow setup a secondary group of log files that log every action taken on the server where your average user wouldn't know that they're being logged. Perhaps if a hacker got in and messed around or something you'd be able to see what they did, but they wouldn't have permission to modify the file.

I have a ftponly user "rom" in my box. This is used by our vendor to send files through ftp. When they send files the ownership of files are all the same as user name group created in this machine.But our application engineers use another user name "deb" to process these file. But as the owner of these file are "rom", they cannot process with their user. Manually they modify the user name and group and then they able to process.The group ID of the two users are different and its application dependent.how should the ownership will be modified automatically or is there any workaround or script to modify the ownership of these file for application user's?

I have a drive that originally was used with a Linksys Network Storage Link (NSLU2), then stopped working with it. Now I'm trying to get the files off the drive. When I USB connect the drive to Ubuntu, I can see the files, but I'm unable to open them or copy them. The error message is: "Error Opening File: Permission Denied". I did have permissions set on the NSLU2. So far I'm not able to find a way to get around the permissions issue in Ubuntu.
I have used apps like EASEUS Data Recovery and Recover My Files. It appears that they are finding the files and are able to access them, so I know it can be done. I don't mind spending some $, but these apps are taking a *long* time to run. If I could properly access the files in Ubuntu long enough to copy the files, I think I'd be all set.
look at this : Uploaded with ImageShack.us how can set permissions in linux like this? I want one user can delete files but can't modify them and ... in linux i have 3 group to assign read write and execute them. is ntfs flexible than linux file system?
View 4 Replies View RelatedI completely switched to Ubuntu 6 months ago. I kept my secondary sata hd as ntfs for a while but started having permission problems. I switched it to ext4 and that worked for a while but then it started having permission problems again. Specifically, I can't execute anything on that hd drive. I converted it to ext2 and it still didn't help. I have 2 executable modules that I moved up to the root directory to make this simple and they look like this:

I am having difficulties assigning permission for wordpress to write files. I am having problems with the permalink within wordpress and I think it might be because of the level of permission wordpress has. Currently on my system I need to set permission to 777 in order for wordpress to write to the .htaccess file.
I am running my website on a Ubuntu machine. Version 10.10 Apache2 2.2.4
However, when I leave the permission level set to 777 I still cannot get the permalink to point to the corrent page......See my discussion on this here. [URL]
I think what I need to do is change wordpress to use a user permission or a group permission and not "everyone". I would rather have wordpress setup to login as a specific user before it can write over a file.

I have a bash script that will unencrypt a file, use the unencrypted file for a very short time and then delete the unencrypted file. The problem is that my password is in clear text
[code]...
Obviously this isn't so secure, but I need the script to be non-interactive. How do I hash, encrypt or otherwise make secure the password for the openssl command? I know that the openssl can protect passwords, e.g.:
openssl passwd -crypt "password"
But can I use this protected password in my script?

View 8 Replies View RelatedI have this project for my operating systems class and I have put together the basic flow chart to aid me in writing the program. I know how to use pipes as a buffer to hold info. I know how to create a binary semaphore. But what I dont know is this:
How to "use a delay adjustment parameter K in the critical section to adjust the speed of the display process to show that without semaphore protection the displayed contents of the buffer are randomly interleaved."
First off, I am definitely not asking anyone to give me the solution. But I do need some guidance. So I figure there will be an if statement with two options:
1. If true, use semaphore protection to enter/exit critical section
2. If false, no semaphore protection -- this is where the contents of the buffer should be interleaved.
Now does that mean that as each child process enters the non-protected critical section, it should "sleep" for a randomized time? I mean, will this allow my output to be interleaved?
So lets say my command line looks like this:
what happens to the 100? Is it randomized using rand and srand and passed as a parameter to sleep() inside the critcal section?

View 1 Replies View RelatedI recently set up a machine with Ubuntu 10.4 LTS to help to replace an aging VAX mailserver that was the DMZ mailserver for the company I work for. I set up a default install of postfix (via apt-get) to function as a DMZ border device that routes between two internal mailservers based on subdomain aliasing via internal DNS.
The problem is that although I have installed no anti-spam or anti-virus options, mail sent to this machine from any outside source containing a password-protected zip file is being rejected with error:
552 Password protected zip file found inside of the email
At first I'd thought that possibly it was the sending mailserver issuing this error, but after further testing I found that no matter the source, any password protected zip file is immediately rejected. Being as we're in a HIPAA-sensitive environment, this has been relied upon as a backup for people to do one time encrypted file sends via email. The file in question is relatively small, and I do not have any quotas on, and the same test file sent two ways (one encrypted zip and one non-encrypted zip) caused the encrypted zip only to fail.
As stated before, I do not use any type of antivirus or antispam measures, no header or body checks have been put in place, and in the course of trying to troubleshoot this problem, have probably opened my server up more than is strictly wise. I really need to enable this feature as being unable to take encrypted zips puts the entire migration at risk.
My system is setup like this: 1 250 gb HDD, with a 20 gig partition for /, 200 gigs for /home and the rest is a swap file. I also have a 1 TB (ext3) and 1.5TB (ext4) hard drive that are also installed, mounted to /Shared_1TB and /Shared_15TBI just installed Ubuntu 9.10 and everything seemed to be fine. I installed all the updates, install the Nvidia proprietary drivers and got my HDMI audio working. I went to try and play a video to see what would happen.... there are no files in /Shared_1TB. It is totally blank. I tried making myself the owner, and while this worked it didn't help anything. I tried unmounting and remounted, however it kept saying it was busy and wouldn't remount it. At this point I was a little panicked, so I threw in a LiveCD and low and behold once I mount it in the LiveCD all my files are there.

I use Ubuntu 9.04 exclusively on my own machines, but I have a couple of flash drives that got infected by some corrupt windows executable (*.exe) files, probably by somebody's trojan (they are Cruzer 4GB so came with installed fancy programs that I dont need but didnt remove and Windows keeps installing unwanted ini files and other trash every time I use them in somebody elses machine or in an internet cafe). I deleted quite a few files, but some are stubborn.
$ sudo chmod +w-X doesnt seem to work. How do I unprotect and remove them? The filesystem is vFAT.
I suspect the files were created by some kind of a trojan as my work requires my flash to be pretty promiscuous.
When I 've backed up all the good files I need, I'd be happy to reformat the flash drives as straight vanilla data storage and retrieval, provided I can still use them on a variety of machines running MS windows as well as on my Linux machines. Any guidance on reformatting?

View 6 Replies View RelatedI've been running various releases of Suse Linux on my home PC for about 6 years (currently running Suse 11.2). The old hard disk in that machine is starting to experience read errors, so I bought a new disk to put into the PC which otherwise works fine.
So I figure now is a good time to give Ubuntu a try. I plan to install the KDE version of ubuntu on the new drive, but once that's finished I will want to mount the old disk and copy as much as I can off of it onto the new disk (JPEGs, old documents, stuff under my home directory.
The old disk uses Reiser. I have read various threads concerning problems with mounting Reiser FS disks under ubuntu, but many of them are old so it's not clear to me what the current status of support for Reiser in ubuntu is.
I am planning to do the following:
1) Remove the old disk from the PC, put the new disk in its place.
2) Install kubuntu on the new disk.
3) Put the old disk back into the machine along with the new one with the old one being the slave/secondary disk so that when I power up the machine, it will be running ubuntu off of the new disk.
At this point I will want to mount the old disk so I can then start copying files off of it.
What do I need to do to mount the old disk, keeping in mind it uses the Reiser file system?
I'm using xarchive and I have unrar-3.7.8.pet installed. Normal rar files open without problem. Tried opening a password-encrypted rar file and it hangs everytime.
