Ubuntu Installation :: WYSIWUG HTML Editor - Ignores Used Fonts Unless Re-edit And Ignores Css On Links
Aug 17, 2011However - is there such a thing as a decent HTML editor like dreamweaver? Komposer is buggy as hell - useless! Bluegriffon, well umm - screen fonts are bizarre, especially in viewing source code - brake down, multicoloured obviously a bug - no deb either, looks like a windows program install (?). This does look really good, but is unusable as I cant see in souce code view without getting a headache! Also, ignores css on links.
Seamonkey - you have to open browser then editor, then open your file. Ignores css totally. Amaya - ignores used fonts unless you re-edit - and ignores css on links. Weird way to select things as well, such as images. There must be at least one decent editor?
Security :: Setting File Permissions For File /var/log/Xorg.0.log?
Jul 7, 2009i am trying to set the file permissions for the log files "/var/log/Xorg.0.log" and "/var/log/gdm/:0.log". These files seem to be created when a user logs into a whokstation (my guess so far). I am trying to comply with a security mandate that all log files in the directory /var/log are set to 0640. The two mentioned files always seem to have the permissions 0644, does anyone know where and when these filea are created and how I might set the permissions when the files are created

Mar 3, 2010I am setting up a new ubuntu server, and I am quite new to linux. This server will be used as code repository for a project I am going to be working on. I plan to setup 3 groups for users: dev, test, doc
- for various developers, testers and documentation users.
I would like to setup the following permissions on the main code repository directory:
dev - write permission
test - execute permission
doc - read permission
public (anyone outside these groups) - deny all access
I am unsure what chmod setting to use, or if this is even possible in ubuntu.
Ubuntu Security :: File Permissions With Apache
Jul 6, 2011I know how to assign file permissions and other tasks like user to group, but I'm stuck with a situation in how I should set up my system.So I have a LAMP server set up. I'm not the only developer so I created a group called "developers" for my other users "Mike," "Alex," and "Cindy," which are developers (I'm Mike by the way). I know that "www-data" is the user and group Apache uses.This is good because only I have permission to update the production site, but for the dev site, it's a different story.

Jan 25, 2011Is anyone aware of a detailed "flow chart" -- arrows and decision diamonds, etc -- that describes the file access and permissions processing? I would love to see that diagram. Years ago on a platform far away (Digitial VAX/VMS) their manuals had such a flow chart that covered not only the user-group-owner and read-write-execute permissions decision making but also include "access control list" processing at a superficial level. If someone has access to the VAX/VMS flow chart, that might be a start toward sorting what linux does.

Feb 24, 2011However, configured a website on a dedicated server using WHM/cPanel. The site was uploaded using the master account for the website.
The security issue is public users are able to upload files on to my server via the website. They could even access the root and execute whatever they want on the server.
I have consulted with 2-3 Linux experts. According to them, the PHP user has rights to execute anything on the server or upload & store files in whichever folder they want.
Can I protect my folders to avoid file uploads via the website. The application has security vulnerabilites. However, I want to prevent hackers to enter my site until the vulnerabilities are fixed.

Security :: Debian Shows File Permissions Change When Copied To A Windows Partition?
Dec 10, 2010Some time back using this computer a SucKit rootkit was found. Having dd urandomed the drive, flattened CMOS battery, flashed BIOS, run Knoppix live CD 6.1,using no flat pack battery (laptop), and memtested the RAM, I am still having problems with what I suspect is a javascript file that tries to reload the rootkit from? firmware. I suspect the firmware as everything else should have eradicated it??
Also it or a hacker via a backdoor then corrupts the drivers so devices malfunction. Windows security programs and rootkit detectors don't seem to pick it up. Fresh install of Windows or linux after the above still show this problem, though internet not used. The person who admitted rootkitting this machine is capable of writing java programs or using javascripts to do all this.
When viewed using Ubuntu 8.4 files and dates on a Windows partition appear normal both in file manager and terminal. However booting using Knoppix CD these files are all green, and I cannot change their permissions, even as root. ie: everything is green including text files etc. If I copy them to a linux partition, I can change their permissions and make them nonexecutable and nonwritable. Also on the Windows FAT32 partition the . directory has the date 1 Jan 1970.
If I disable any green files, I can shutdown and reboot cleanly. If I don't I start having problems shutting down [/usr/sbin/init ?] And always these follow a pattern:
Can't remember details as I have now corralled the beast but error messages relating to:
nfs-server
inet.d/statd
are the start of these.
Ubuntu :: Nautilus Ignores File Associations?
Apr 19, 2011I have my default text files (also source codes etc.) associated with gedit (checked with ubuntu tweak).However, nautilus tries it to open with some "notepad" - dunno what it is I don't even have such a program. Files are OK, opening them directly from gedit or vim is fine.Some weird things:- nautilus correctly displays gedit icon- I have dualboot system with windows 7 and notepad command looks like it came from "there"- when I click on open with -> gedit, file is correctly open. However this option is not remembered by nautilus (even though I checked it as always open with ...)- nautilus (after clicking on open with) also suggest to use some "iexplore" command, I totally don't have idea where that came from Any suggestions? I really don't feel like using another file manager, but opening text files is pretty elementeray action and should work properly

Ubuntu Security :: How To Truly Replace All Permissions For Mac HD
Apr 7, 2010I am not putting lnux on my mac, so I don't think it goes in the Apple section and Security is the closest I could find regarding file permissions, so excuse me if I am in the wrong area for this question. I need to back up my macbook (OSX) data. I do not have another mac nor do my friendsw.. I do have a PC running ubuntu 9 though. So I hook it up and can see it, but all the document are locked and I dont have permissions.... now with windows I know how to take over permissions, I have looked online and the closest I found is using the temporary root user command to view all locked files but that gets me to about 25% my data.

May 17, 2010I have upgraded to Lucid, but was having the same issues on Karmic. I made a 2nd user acct we'll call X and we'll call the original acct Y. All of these issues only happened after creating X.
On X I have: sound Things wrong with X: I don't have the ability to modify any folders (even ones that are made from X's acct), I can't change the password or even access the Users and Groups, I can't modify any browser settings in Firefox but can on Chromium, the option for wireless is completely gone
On Y I have: the ability to access users and groups, the ability to modify all folders on either acct, the ability to change any settings on anything Things wrong with Y: no sound (doesn't even show the driver, but the driver is there on X's acct), wireless is completely gone (just like X's acct), even though I can access Users and Groups I cannot modify anything about X's acct
My first thought was to completely delete X since that's when all the problems began, but I'm afraid that since X seems to have "stolen" my sound card, that will be lost forever. I am also afraid that since neither account has wireless deleting X might hinder ever getting it back.

Ubuntu Security :: How To Change Permissions To Allow EXE And JAR Files
Apr 4, 2011I've been using Ubuntu for a few years and I am having issues trying to load .jar files and .exe files in Wine. I keep getting an error message that says my computer doesn't have permission to load these files. I've done some research and found people saying to enable the file as executable in the files properties, to enable executable in the permissions folder, and to allow source code on the Ubuntu Software screen, but whenever I try to check these boxes, they immediately revert to having a line through them instead. I remember when I was running Ubuntu a few years ago I was able to completely disable this restriction in terminal, but I can't remember what I did.

May 24, 2010I may not be a code worrior, yet I have been a Ubuntu convert from Apple for about 3yrs now. Since 1984-2006 now hackers or viruses. And Until now Ubuntu has been clean, well I have been good with repos, etc.
1. Recently I found "Odd" behavior with my Amarok 1.4 player, ffmpeg, winff.
2. During a Synaptic upgrade there were some "unauthorized changes". I have seen this before due to some of my software, so I ignored it. . .
To my bewilderment, "It" erased Amarok 1.4 player, ffmpeg, winff, all image kernels, claimed domain over my system permissions, and external HD. B4 I shutdown, downloaded LUCID 10.4. . . restarted, then copied over all info possible to minimize a complete delete of my system. Upon restart, indeed all kernel images were gone, Only live CD allowed me access to repartition my HD.
NOW. I have Lucid running, and have been denied access to my external HD and partitioned (internal HD). I used Nautilus to copy over files to my internal laptop HD, yet permissions continue to be an issue. The INFECTED FOLDERS are owned by "User 999-user#999. I must micro manage every folder and file to gain "partial permission". The dialog box stutters and never allows me to go down to "Root"
Ubuntu Security :: Understanding Unix Style Permissions
Jul 20, 2010On Windows, you can go to a file's permissions and it's clearly stated who can do what. You can choose between individual users or groups such as 'everyone' or certain types of users such as 'domain users'. You could create a clear cut list of every single user/group on the system and what their permissions for a file are and have it neatly displayed in a list.On Unix, we have octal permissions and sticky bits. I understand the whole concept of rwxrwxrwx (777). The first three are what the file owner can do, the second is what the main group the user belongs to can do, and the third is what other users can do.
But, when you view a file's permissions you are only getting the permissions as they apply to the user that owns the file. For example, as I understand it, if I viewed a file that only the root user had rwx permissions on and everyone else could only read. The permissions would show up as rwxr--r-- (744). But, those same permissions would show up to any user as 744 as well. Since the last 3 characters are what applies to "other users" (pretty vague). How would someone know what users in particular those permissions apply to? There could be one "other user" that can rwx that file and another "other user" that can't.Also, why just stop with the main group? What about other groups? A the user Foo's main group he belongs to might be Foo. But he could also belong to the groups Boo and Zoo, which belong to other users and would give him full rwx permissions over Boo and Zoo's files just as if he were Boo or Zoo.
Then you have the whole sticky bit thing that makes it so that files can be owned by the same person and at the same time be made use of (to varying degrees) by other users. To chmod the UID you'd chmod 2777 or for GID 4777 (just an an example). I did this for a file and it allowed a standard user account who was previously unable to run the command to be able to run it. But, how can that work when I didn't anywhere specify what particular user (or groups of users) that sticky bit applies to?
I'm confused about this whole thing to the point that I'm not even sure exactly what questions I should be asking or even if my examples are even 100% correct. I just sort of ranted about some specific things that floated to the top of my head. Permissions are easy to understand when your running a Unix-like system on a single user desktop. Because the only users/groups you have are root, the single user, and various system users/groups that you don't really need to worry about. So a file with rwxr--r-- means that only the Root user (not even members of his group) can edit the file and you can't unless you use sudo. Because the "other user" in the last 3 characters always just means you. But, things seem to get a whole lot more complicated when you start adding in multiple users. Can someone explain this or link to a "for dummies" article that can explain all of this to me in a way that someone who's used to Windows style permissions can make a connection between the two OS families and their way of handling these things?
