I`ve been given a project to design a program that will interface with a hardware device through the parallel port.And so far it`s not going go. I managed to write the programe an compiled it, but when runing it the compiler says: 'changing ownership of'and then the file name then it continues to say, 'operation not permitted'.
I wrote this because i was able to use openmpi to run mpirun on my 12-core workstation rather happily since day 1 I setup the system a few months ago. Yesterday when I tried to run a big job under mpirun, the job crashed rather quickly, the error message was something like mpirun process exited blah blah with signal 11 (Segmentation fault). Interestingly (or annoyingly) a job required less memory ran okay.
Since I never had this problem before, I thought it was the hardware failure. I called my IT guy to explain the problem and he is kind enough to suggest to put a line
ulimit -s 40960
in my .bashrc. And it works! But I have no clue why mpirun misbehaves out of a sudden, and that ulimit setting solves the problem completely. I would like to learn from this incident.
I am having a problem when I try to login as su.I type the command SU and then the password as normal and I get su: cannot set groups: Operation not permitted I am not sure what could of caused this error and how to fix it.
I just setup a server using ubuntu server edition also installed apache, php, mysql and phpmyadmin.. when i try to setup FTP permission via winscp i get the error /var/www/phpinfo.php: Operation not permitted. ans so on for other files present there..
I'm trying to setup ACL (access control lists) on my /var/www folder so myself and my roommate can work on a site together. I've installed ACL and added the acl option to fstab for the root (/), but whenever I try to setfacl, I still get
setfacl: /var/www: Operation not permitted
I can however share folders in my /home directory so I guess it has to be that /var isn't getting the ACL option. Here is my fstab file:
I couldn't install everything during setup of my debian server, so I installed post setup through the Add/Remove Programs. My guess is there is so much installed that either DHCP is not setup properly or there is a firewall installed. My computer found an IP address from my router but cannot connect to the DNS service or ping my router. I type: ping 192.168.1.1 computer resp: "ping: sendmsg: Operation not permitted"
I'm setting up a network backup on a workstation here using Webmin. I'm backing up to a local FTP server. I set everything correctly (FTP credentials, directories, etc) but I get an error saying "Could not create file" and another saying "Cannot write: Operation not permitted"
After upgrading to Debian 8, I'm having a bit of trouble with systemd, since I'm not used to it (seeing as it was all init when I started). I tried to use a tutorial to create a new service and one step in it was to run
Code: Select allsystemctl enable xxx.service
Unfortunately, every time I run systemctl - even without parameters - I get this error:
Code: Select allFailed to get D-Bus connection: Operation not permitted
Below is the oneliner that I am using to exclude all of "." hidden directories within the same directory.
Code: cd find . -depth ( -wholename ./.* ) -prune -o -print | cpio -oav > /media/caca/extract/full$date.cpio it works fine but when I extract the files from the full$date.cpio archive it appears to have worked but gives me permission errors:
Code: cd /media/caca/extract cpio -ivd < full061411.cpio cpio: Selection_001.png: Cannot change mode to rw-r--r--: Operation not permitted Selection_001.png cpio: Selection_002.png: Cannot change mode to rw-r--r--: Operation not permitted Selection_002.png
i have written one backup script in linux workstation.The backup script will do zipping files and moved to the backup directory(i,e /net/ts-bcn/sb_backup/sand). while moving zipped files to the backup directory i am getting some error like this #error:mv:failed to preserve ownership /net/ts-bcn/sb_backup/sand operation not permitted. i am getting the file owner and group owner as nfsnobody for the zipped files.
I was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??
I am running Ubuntu 9.10 Karmic Koala, and I am having problems with GDB. When I attempt to debug a C program in kdbg or codeblocks, the output terminal will display this message: "warning: GDB: Failed to set controlling terminal: Operation not permitted" I have searched quite a bit and I have not found a fix that works.
I am running the latest stable versions of all my software supplied by the ubuntu repositories My system meets all the dependencies for KDBG and Codeblocks
I am running gnome, but the KDE files installed by Synaptic are version 3.5.10 I have KDBG version 2.1.1 I have GDB version 7.0-0ubuntu1 I have CodeBlocks 8.02-0ubuntu4
If anybody needs any more information in order to give ideas or knowledge on how to fix this just let me know
I run a small site and today I've discovered that my site is down. I found that cPanel has flagged the account suspended even though I haven't got any quotas on the account. I don't know what went wrong. I've tried to unsuspend the account in WHM but a certain part of the function failed.
safe_userchgid: chown: /home/crocbits/public_html: Operation not permitted at /scripts/cPScript/SafetyBits.pm line 93.
After searching the internet someone mentioned that the problem might lie in the permissions of the public_html folder. I had a look at the permissions and the folder had no permissions d----- When I try to chmod the folder I get this error:
chmod: changing permissions of `public_html': Operation not permitted
I have no idea what to do next. All the files in the directory are locked too. I tried to move them but this command isn't allowed either. I ran these commands under the 'root' user in SSH.
I am running Oracle Enterprise Linux x64 5.5 on an HP Proliant DL380 G6 attached to various SAN's via fibre channel. I have setup multipath, edited multipath.conf, lvm.conf, and after some trial and error, everything behaves and looks as it should in regard to multipath. However, when I try to resize a multipath ext3 lvm filesystem, The operation runs for a while, but then dies and I get the above error. I then see this error in /var/log/messages:
-I am only using the /dev/mapper/ paths to the filesystem (ie, resize2fs /dev/mapper/testvol-lvol1 128G) -if I unmount the filesystem, resize2fs works fine -Have tried removing and re-adding journal file via tune2fs with no luck -The VG has plenty of room in it and is composed of a 100GB and 200GB partition. -Inode resize is on in the filesystem
I am wondering if online resize2fs is only for small filesystems or not recommended as a best practice or just not generally done??? As I mentioned, the operation works fine offline if I unmount the filesystem, but this won't be an option once system is in production.
I have 2 directories in my home folder that I would like to set a size limit on. The directories are ~/backup and ~/temp. Is there an easy way to limit the size of a directory without having to make partitions?
LDAP authentication problem on debian squeeze? To my knowledge, I have everything setup properly to do ldap authentication + local authentication on a host. I can login as a local user. I can login as an LDAP user.
When I log in as an LDAP user, my primary group is set properly. It is an LDAP group. I can change the group ownership of files to LDAP groups using chgrp. So far so good. This all works as expected. The commands getent passwd and getent group work wondefully, and generate the expected results. I can newgrp to any *local* group, but if I try to newgrp to an ldap group, I get the following error:
setgid: Operation not permitted. I've tried googling and asked on #debian on irc.debian.org. No luck.
I updated my lucid alpha testing (64 bit)install after which I am unable to boot into any of my Ubuntu installs(sda11 has a dedicated Burg partition and sda10 has the stable karmic (32 bit)install and sda9 has the testing lucid install) Now I am trying to recover (rewrite Burg or at least grub2 on the MBR) my installs
This is what happens custom@custom:~$ sudo mount /dev/sda10 /mnt custom@custom:~$ sudo mount -o bind /dev /mnt/dev custom@custom:~$ chroot/mnt
i tried a slightly different code with little success
custom@custom:~$ sudo mount /dev/sda10 /mnt mount: /dev/sda10 already mounted or /mnt busy mount: according to mtab, /dev/sda10 is already mounted on /mnt
I also ran a whereis for bash and it also is there
I have a WD MyBook World NAS share mounted with the following options (I tried also other options):Code:cifs nouser,atime,auto,rw,nodev,noexec,nosuid,nodfs,nounix,guest,uid=0,gid=0,file_mode=0777,dir_mode=0777The cp -a, touch, etc. commands can change the file time if the root is executing the command (means NAS supports time setting), but as an user I can't change the file time - with an exception of changing the time to the current time. For an illustration see below:
I have a large file (deflated size: 602191947)that is not saved in my Ubuntu One account. On sync'ing the file is being uploaded, and eventually reaches 602191947 - and then nothing more happens to this file - but sync'ing the following files in the queue goes on with success. I have tried manual upload with the same result. The file is still being marked as 'uploading' even after several tries and log ins/log outs, and reboots. So I was just wondering whether there is a file size limit - can't seem to find information regarding this.
a possibly preposterous question. I am aware that you can designate a swap file or swap partition on your hard drive that linux uses as "memory". Suggested sizes for the swap file that I've seen range up to about 1024MB. Is there a limit to the swap file size that you can set?Basically I am running a perl script that processes a massive B) file (DNA sequence data), etc, and requires around 48 GB of memory to run, maybe a bit less. So, would it be possible to set a swap file to a massive, ridiculous size (~60GB oratever) and successfully run such a script on a desktop?Yes, I am aware that it would massively ow down the process. The thing is, if the perl script normally completes in about half an hour, and I can get it working on a desktop, I don't mind if it takes days or weeks to complete. I really don't. That's because it takes days or weeks to get access to a computer with the required grunt to do it.So, is this a stupid idea? Is it even possible? If so, given a perl script that normally completes in a half hour on a 48G system, if you do this, would it take days? weeks? decades
I've noticed that for files longer than about 8000 lines that gedit has problems opening the file. Was gedit not designed for long files or is there another problem? The same thing also happens on complicated html files. So I hope there is a way to fix this.
I have a self-made application running on a small embedded Linux device (which should not matter) using syslog to output some error, warning or debug logs.There is a "better" syslog daemon installed, called syslog-ng, which have some more features,t I miss a very important one:How to limit the size of the logfiles to some dedicated megabytes. I was able to create rotating logfiles with the configuration in syslog-ng.conf:
I use a wired Dlink Adsl Router GLB502T with its inbuilt dialer configured. Problem is it will not connect while computer is running.When I try to ping the local ip of the modem this is what I get "ping: sendmsg: Operation not permitted" and "/etc/init.d/networking restart" has no effect either.I need to restart my computer every time i want to connect to the Internet.I switch on the modem when the grub bootloader appears and the modem connects without any problem.This problem appeared when i installed Ubuntu 9.04.There was no problem with Ubuntu 8.04.
