I started to use linux (CentOS 5) 1 week ago. And I took lot of imformation from this forum. Is it possible to install two program at same time?
Total download size: 67 M
Is this ok [y/N]: y
Downloading Packages:
jdk-6u24-linux-i586.rpm 19% [========-] 6.0 kB/s | 13 MB 153:51 ETA
It is so boring to wait and I have to wait there is nothing to do something else just centOs text.
I am changing the password of a truecrypt file container. This takes around 1 minute. Why?
time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null"
If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password:
open("/dev/urandom", O_RDONLY) = 6
read(6, "36&{35121221234320234313242312I326235245224300354O)270Q200 201J227224311_212367"..., 640) = 640
close(6) = 0

the Date and time are changing all the time...
Meanwhile, I'm set the clock every day, But I must find a solution ... Do you have a solution?
I created a folder structure as root and now need to transfer ownership to an ordinary user.
This question is linked to this one - [URL]
I have a folder /srv/app-share that needs to be visible/writeable to user1
I tried (as root):
root@server [/]# chown -R user1:user1 /srv/
But that did not work.
Possibly related to this previous question, I would like to be able to run a task for a specified amount of time, then stop/kill it, then start it again. Specifically, I run the Folding@Home application on my Linux workstation. Periodically, it will have trouble logging-in to the home server, and will sit idle for a long time, but not release memory/resources it has claimed (yes, I realize this is likely a bug in the tool, but I can't fix that currently). Typically just the act of killing and starting the tool will allow it to check-in again. So, I would like to be able to run something like:
run_for <time> ./fah6
Does such a tool exist, or should I write a wrapper than nukes the fah6 client after, say, a week and restart it?
I'm rather new to linux, and I have a dedi server. I know how to browse, install, remove etc, all the basics needed to use it. I've installed flvtool2, memcoder and ffmpeg, and at the moment im converting avi files in to flv. Im then passing metadata using yamdi.
However, this process is very timely as im converting loads of avi files at a time.Im looking for a script, or a way where I can execute one command/script and which will convert all files in the directory I specify, then run those converted files through yamdi.Im guessing it would be some sort of loop, and then changing for each file?
I use the system command route from a process (using the system() call). For security reasons the process does not have root privilege and for some reason I cannot use ioctl() either. I tried to set the capabilities of the process to NET_ADMIN and SYS_ADMIN but the route command still failed due to insufficient permissions.
What are the capabilities that I need to set for route to be successful?
I have a really strange problem. I have a few files in a large directory that I want to make readable by everyone. So I try this:
sudo find readme* -not -perm -o+r -exec chmod +r {} ;
and get this:
sudo: unable to execute /usr/bin/find: Success
I don't know why it says Success, because the permissions were not changed. I verified by typing this:
find readme* -not -perm -o+r -exec ls -l {} ;
and get something like
-rw------- 1 root root 536871076 Nov 22 14:06 readme_20101122200429
-rw------- 1 root root 536871892 Nov 22 14:08 readme_20101122200642
-rw------- 1 root root 293458128 Nov 22 14:10 readme_20101122200859
as a last resort, I tried:
sudo chmod +r *
and got:
sudo: unable to execute /bin/chmod: Success
and again Success really means fail. So, I gave up and logged in as root and tried:
find readme* -not -perm -o+r -exec chmod +r {} ;
This time it worked. Why?
EDIT: /etc/sudoers looks like:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
##Me
user1 ALL=(ALL) ALL
i have inherited a mixed bag of sorts: several xp users updating an access mdb with the BE on a lamp stack shared via samba. i have a backup device which gets mounted at: /media/disk... each client record (has) a folder by the companyname on the samba share, and all relative documents are placed there. when the backup script runs, it just copies newer or missing files.
someone has been renaming folders, and not matching the folder name to the related companyname from the mdb. so...the backup script captures and duplicates the data in the renamed folders. some client records also have periods in the name (not required from a data pov), such as 'Company Ltd.' instead of 'Company Ltd'. i can produce a list of company names as the folders should be found easily enough, but get a little stuck with the linux scripting.
i can easily remove and further prevent any unwanted punctuation in the company name on the client record, and create the correct folder name on the samba share with vba, but would also like to:
-for each 'client activity' folder on the backup device
-rename the folder by removing punctuation marks
or
-delete the folder if is a dupe
i tried: ls -al | grep '&' - it properly returns only those lines with an ampersand in the folder name, but returns all folders when i try that with a '.'.
what would be the easiest method to do the renaming? i thought if there was a way to change ownership of the mounted device, then the vba code (easy to write) would be simple.
OK - i just ran chown -R on the external device, changing ownership to (me) instead of root. didn't want to because it took too long, but can now use the MoveFolder method of the filesystemobject from my app to do the renaming instead of some sort of bash script (which i was dreading).
I am trying to set the umask for a process(orkaudio) which is running as the root user.This program creates dir and files and I need the umask to be 022. I have edited my /etc/bashrc -- and when i type in umask i get 0022 --- Not sure how to go about getting this resolved...
View 1 Replies View RelatedI am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.

View 9 Replies View RelatedI need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid()
2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process
3. Setting UID = 0, using setuid(0)
4. Calling the prctl(), function to keep capabilities
5.Switching the UID from root to User_ID of the process
6. What we have now is a process with root capabilities as a non root user
7. On printing Permitted, Effective, Inheritable capabilities, I get the following
--> Permitted = 0xfffffeff = Effective
Inheritable = 0x0; with UID = 1001;
8. I then try and set the system time with --> system("date -s 10:00");
9. I get an error: date: cannot set date: Operation not permitted
10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.
I'd like to change a files modification date "only" without changing the time. I'm aware of the 'touch' command but is seems like it only allows changing both the date and time, and not one of them. Any ideas on an easy way to change a file's modification date without also changing its time? (I have a long list of files and thus would like to run one to command to change them all)Example: Change a file's (month) timestamp from "2010-09-23 11:59:23" to "2010-10-23 11:59:23"Background: I accidentally set the wrong month on my camera and ended up with all photos having a modification timestamp with the wrong month.

If I set W7's time to the correct time and then reboot to Fedora, Fedora's time is then 7 hours early. For some reason I can't get both OS's to agree it's the same time.
