Security :: Changing The Permission Denied Error Message?
Jul 9, 2009
Is it possible to change the general permission denied error. I have some rather young users on this system that think they can "hack the gibson" and I would love to change the general error message to something a little more rude/funnyex:# cd restricted area
-sh: cd: restricted area: Permission deniedI am curious if its possible to change the error message in general?ex:# cd restricted area-sh: cd: restricted area: (funny/rude message goes here)Quick info:This is a Gentoo 2008.0 system, I would also love to do this on my slacware and OpenBSD boxes as well just for kicks.
I am trying to use Wireshark and on startup the program pops up a window saying: Couldn't run /usr/sbin/dumpcap in child process: Permission denied Are you member of 'wireshark' group? Try running 'usermod -a -G wireshark <username>' as root.
I ran the usermod command to add my account in the group and checked it Code: less /etc/group wireshark:x:490:myaccount but the same error message pops up.
I have got centos 5.3 running on my system. I have installed vsftpd and created a separate folder to upload files (upload folder created in/var/ftp/pub). From my client end I can download ftp files but when I try to upload files from my client I get a error message 550: permission denied. The upload folder has full permission ie 777. Checked the ftp config file everything looks ok.
I did create an rsa certificate with ssh-keygen using my root account on a client: ssh-keygen -t rsa -b 2048 no passphrase I did copy the rsa pub_key from my client to the server scp id_rsa sampleuser@sampleserver:/home/sampleuser/.ssh/authorized_keys
I did change the ownership to the "sampleuser" of the pub key file on the server: I trayd to connect: ssh sampleuser@sapleserver
I get that: permission denied (public key)... I know I do smth wrong but I don't know what.
This is weird, today I updated my system and while trying to visudo from single user mode got
"cannot read /etc/shadow: Permission denied"
which kept me from doing anything until I switched to file permissions of 400 on shadow, then back. Is this being experienced by anyone else or just me? /etc/security/limits.conf doesn't seem like it wants to change in enforcing mode either and I can't find any alerts to provide clues on the situation.
nfs mounted directory which is mounted rw. I and everyone else are members of a common group. We all have write permissions in the tree: All files and directories in the tree are in the common group. All directories are set to 775 and all files are set to 664 or 775, as appropriate.If a file is owned by someone else, even though the file and the directory are group writable, I get permission denied when I try to chmod the file.
Here's the command synopsis: 997 > ls -l portparms.txt -rwxrw-r--. 1 bdaugher fc 4091 Sep 5 2003 portparms.txt
I have, say, 10 machines, connected via NFS and NIS. There's a server which exports the /home using NFS, and exports the user names using NIS. All machines are working fine. I am able to ssh to the machines remotely and get my work done.Recently though, one of the machines (say M, for easy reference) would not allow any other machine on the NFS network [or outside the NFS network] to ssh into it. Every time an ssh attempt is made, 3 IP addresses [including the machine from which an ssh attempt was being made] are added to the /etc/hosts.deny file on M, and the error message on the other machine shows 'permission denied' after the password is entered. I tried using various options that ssh provides, but I cannot figure it out. I also tried uninstalling and reinstalling openssh-client and openssh-server on M, but it didn't change anything.
Another point to note is this: another user made use of M before, for a while, by disabling ssh passwords - so he could access M without having to enter his ssh password. That individual can still log in to M. All others who require to enter a password cannot ssh into M.
I have recently bought a new laptop, installed my first linux OS on it (Ubuntu 9.10) and an external hard drive with 500GB on it for backup. For the first few days my external hard drive was working fine, but then eventually it wouldn't let me copy/move/delete stuff to and from it. So I kept trying to change the permissions but it wouldn't let me.
I figured this would be a very very common problem, so I looked up some forums to try out the methods but they didn't work. So I thought I would ask you guys for help because I am pleased with the support. I wouldn't think this would be a hard problem to solve.
I have an external hard drive that has all of my Apple Powerbook G4 files on it. I plugged in my "Journal Extended" external hard drive into my new HP laptop with Ubuntu 10.10 on it.
All of my files are on the hard drive still, however lots of them have a little X on the folders and when I try to open them it tells me I don't have permission? How can I force the permission for everything on my external? It's my own files and I can't even access them lol.
I have a CGI script that when called runs another script as a different user. Yet when the script does run I keep getting a permission denied in the logs and the script fails
In the sudoers file- Defaults env_reset www-data ALL=(charly) NOPASSWD=ALL
For the full question- When looking at /etc/sudoers there is the defaults line that you can add things to. When doing a sudo -L so that I can see what I can put on that defaults line. Can an individual user have specific defaults? Ones that don't effect the rest of the people in /etc/sudoers?
Whenever i copy ELF or BIN files from the filesystem of linux i must get permission denied. For this case i have gone through the linux security module but didn't get much help regarding the permission denied only in case of copy of ELF and BIN files from filesystem. how can i proceed in this. WORK DONE:
1. Downloaded linux-18.104.22.168
WORK NEEDS TO BE DONE:
1. compile the kernel with some modifications in linux security module to get the desired results but this time i am unaware of that.
I am trying to wade through the semanage jungle to get permissions for a tftp client. I followed the HowTos [URL] but I get the following at the client:
tftp> status Connected to 192.168.1.101. Mode: netascii Verbose: off Tracing: off Rexmt-interval: 5 seconds, Max-timeout: 25 seconds tftp> get hello.o4 tftp: hello.o4: Permission denied
I finally figured out that the firewall directives shown at the end of the HowTo refer to semanage although the options are stated incorrectly according to the man page for semanage. I did insure that the file hello.o4 in /tftpboot has read permission for everybody.
I have a shared directory on another machine but I can't get it to mount. The permission denied doesn't say where/which permission is denied. Is it on the remote on on the local machine? The remote has sharing enabled for the shareddocs directory and after I have mkdir'ed the local mount point I open it's permissions too.
The verbose response from mount.cfis looks like this:
mount.cifs kernel mount options: unc=//192.168.1.102shareddocs,domain=WORKGROUP,ver=1,rw ,username=clive,,,,,,,,,,,ip=192.168.1.102,pass=** ****** mount error(13): Permission denied Refer to the mount.cifs( manual page (e.g. man mount.cifs) The man page does not have a list of error codes.
When trying to mount samba share off of domain member server sysimage in Windows receive error "There are currently no logon servers available to service this logon request". When trying to mount.cifs from PDC to samba share on sysimage receive error "mount error(13): Permission denied".
PDC is ClearOS 5.2 named "dc0" Samba file server is CentOS 5.5 x86_64 named "sysimage" dc0 Samba version is samba - 3.5.5-1.1.v5.i386 sysimage Samba version is samba-3.0.33-3.29.el5_5.1.x86_64
dc0 is configured correctly to my knowledge, windows machines can join domain, domain users can log into windows machines, user directories are mapped properly, logon scripts run properly. sysimage ldap authentication is set up as shown in "Procedure 7.1.
I couldn't able to change file permission of files residing under /media/* Under /media all the NTFS partitions are mounted manually (gnome GUI) using root password. File properties of file under those NTFS partition shows SELinux context is "fusefs_t". I guess this is prevention from changing permission of file. How can I over come this?
I had Fedora 8 installed in few clients and a server (same server for NFS and NIS), and NIS and NFS configured, and was working fine. Yesterday, I upgraded few client computers to Fedora 15 (server is still same), and configured NFS and NIS client. NFS is working fine, I can see home directories.
For NIS: ypwhich, ypcat passwd gives me correct uutput, ypbind is running. The problem is, I can't login to NIS client. The error is: Permission denied, please try again. My nssswitch.conf is
I'm having a permissions problem with Ubuntu and apache. There are two users, I'll just call them A and B. All of the files belong to A and group root. I'm logged in as B and I have admin privileges. My website is working just fine but when I create a directory in the web root, change the owner to A on the directory and all files I still get a Permission Denied error when I try to access it from the web. I've also set permissions to rxwr-xr-x on the directory and all the files. So I don't understand what's going on. Why am I still getting a permission denied error?
I want to use SSH to connect to my desktop. I have used Ubuntu 10.10's encryption to encrypt my home folder (thus encrypting my .ssh folder). This means that the OpenSSH doesn't have access to my .ssh folder. When I try to log into SSH before logging in on the local machine I get the following error:
If I log onto the machine, then use SSH it works fine. I want to use key based login, One way to get around this error would be use a different authorized_keys file, but I don't know of a way to do this. This is the contents of my sshd_config file:
# Package generated configuration file # See the sshd_config(5) manpage for details # What ports, IPs and protocols we listen for
I am using Ubuntu server edition 10.04.1 running in Vmware server 2.02.I am connect via Putty so I can use copy and paste.My first goal is configuring a ftp server using PureFtpd using this guide.In section 10 I need to write this command
I'm trying to create a folder using the archive manager to install Resin (web server) in the usr/local folder but I get the error message 'error creating directory: Permission denied.' Is this the easiest way to install an app--by using the Archive Manager--and if so how do I establish the correct permissions.
I'm breaking my head on this.I want to create a development environment. This means that I want to be able to create/change files myself, but php should be able to do the same. I installed a lamp-stack using tasksel. Afterwards I installed phpmyadmin. So far so good. Going to http://localhost shows "it works".
Then I created a folder /home/hwc/www and created a new apache site called hwc, disabled default and enabled hwc that points to /home/hwc/www and has the directive AllowOveride All set. But when I go to http://localhost know I get a 403 Permission denied error. I've tried several trings like changing ownership of /home/hwc/www to www-data:www-data, to hwc:www-data, to hwc:hwc, but all to no avail. Even adding www-data to group hwc and hwc to group ww-data did not help. According to other posts at least on of these solutions should have worked, but it did not. I could probably fix it by letting apache run as hwc, but that doesn't seem right.
