Ubuntu Servers :: Vsftpd Chroot, Creates 550 Error On CHMOD Command?
Jul 14, 2010
I've been searching the web, without finding any sollution to my problem.vsFTPd is acting really weird. I've never seen this problem before, and I've been using vsftpd for some years nowWell.. The thing is, I've made a user that chroots to the folder /var/www on my server. And when I then try to chmod the file /var/www/htdocs/testsite/index.html through my ftp-client, I only get the error "550 SITE CHMOD command failed.", and when I then check in my /var/log/vsftpd.log it says
Code:
FAIL CHMOD: Client "192.168.50.58", "/htdocs/testsite/index.html 777"
Which I think would mean that it tries to chmod the file "/htdocs/testsite/index.html" instead of chmod the

I have a problem with uploading any file to my Suse 11.1 with vsftpd. The active (not commented out) settings in my /etc/vsftpd.conf are:
dirmessage_enable=YES
chroot_local_user=YES
local_enable=YES
anonymous_enable=NO
syslog_enable=YES
connect_from_port_20=YES
pasv_enable=YES
listen=YES
ssl_enable=NO
And I added umask 022 to the user login script problem I have: I login with user and password that exists as a local user on my suse machine. I can read and download from my homedirectory, but I cannot upload with filezilla. Then I get the error: 550 permission denied critical file transfer error

recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.
II Software selection :
1. MTA - Postfix
2. POP - dovecot

I am new on ubuntu and I really don't have any background on making a server. To be frank is I am still a student learning ubuntu server, how to make and configure them.
My problem is that whenever I type the command:
/etc/vsftpd.conf
an error message says that:
-bash /etc/vsftpd.conf: Permission Denied
I am still discovering what are the commands on the vsftpd server. By the way I am using the server on VMware.

In a script that I'm still writing, I'm trying to build a package from source within a chroot'ed environment. 1) I could chroot and then cd to /usr/src and then manually install the package. 2) I could chroot and then run the installation script from the proper directory. 3) What I want to do and what's giving me issues, is to issue a command similar to this:
Code:
chroot /root/me/here cd /usr/src
...and have it do the installation after changing to /usr/src.

I'm such a newbie when it comes to Ubuntu, or any Linux varient, period. I was trying to install a driver for an HP All-in-One Printer and was trying all kinds of commands from different Google searches... still unsuccessful in the installation. I downloaded the file to my desktop, but after using a Chmod command someone mentioned, I now have a folder on my desktop named:
hplip-3.9.12
i right-click
select
properties
Basic Tab
Type:folder (inode/directory
Contents:unreadable
Location:/home/mesk/Desktop
Permissions Tab
Owner:root
Group:root
"You are not the owner so you cannot change these permissions". The folder's icon on my desktop has a red box with white circle on the middle right side and a lock symbol above that. I'm the only user so I don't get why the permissions are protected from me, how do i undo this?

set up incremental backups with crontab. I just discovered that tar is not actually incrementing the tar files. I first created the tar files, then in crontab I have:
Code:
cd /; tar -cpf --incremental --exclude-from=/root/ExcludeFromTar.txt mnt/PATRIOT/bkp/home.tar home
I only just discovered that this creates a file whose filename is "/--incremental". I also tried using tar's -G switch instead of --incremental:

I have booted up into Ubuntu 10.04 LTS disc live.
When I type 'chroot /media/(UUID)', I get:
chroot: cannot run command '/bin/bash': no such file or directory.
'/bin/bash' does exist.
Why is this error occurring?

I have spent the last 2 hours trying to get this to work and it is driving me crazy, I have a 11.04 box and have setup some zfs filesystems for data storage, I have 2 users and have created a group called media and added both of the users to the group. I have changed the group of the directory to media and have set chmod g+s
root@saturn:/tank/data# ls -l
total 8

I'm trying to change the root directory to /tmp/somedir using chroot, but even using sudo or su-ing to root I get the message:
Code:
cannot run command `/bin/bash': No such file or directory
I tried copying /bin/bash to /tmp/somedir/, but the same error occurs. What's wrong with my chroot?

I installed Ubuntu Netbook Edition 10.10 on my Eee PC 901 (the one that has 2 SSD's). It all went fine, and I ran the update manager straight after install and config. It installed the updates (all 198 of them!) without error. I was prompted to restart, so I did. I got the error "udevadm trigger is not permitted while udev is unconfigured". I found out that this error is well documented, and I followed the guide at [url](apparently it affects all variants, not just UNE).
It went O.K., until I tried the command "sudo chroot /media/newroot". I got the error that "cannot run command '/bind/bash': no such file or directory". What should I do?
I cannot boot into and earlier kernel (problem/current one is 2.6.35-23-generic) I can only fix it via live USB stick.

How can I give execute permission to chmod command from run level 3.Because in GUI mode we have the execute option in the properties of file. E.g. I gave following command
chmod -x chomod
After that I want to give the execute permission (x) to chmod command again but how from command prompt?

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:

I'm attempting to give a few buddies encrypted storage space through sftp using truecrypt.I have it worked out to the point where the truecrypt volume is automatically mounted when the user logs on, and dismounted when they log off.I would like to restrict each person to their individual home folders. This way, I can control exactly how much space each user is able to use (through the size of the truecrypt volume), while maintaining security through the network due to using SFTP.
I've been looking around, and the only thing I can see is restricting a large group of users to a single directory, this won't work, I need each person to be locked down to their personal home directory.My end goal is to have these volumes "mountable" in Windows through the use of Windows network drives (on a wide network, not through samba on local), or by using expandrive or a similar program. how I can lock these users to their respective home folders?

I'm wanting to setup SFTP in a chroot, which is simply enough to do and I already have it working; however I also want it so that when they connect via SFTP it goes directly to their home directory. Currently I have the following in "/etc/ssh/sshd_config":
Code:
Subsystem sftp internal-sftp
Match Group sftp-users
ChrootDirectory /home
AllowTCPForwarding no
ForceCommand internal-sftp
Which works perfectly fine, however when they connect there are shown the contents of the "/home" directory which they then have to "cd username" to get to their home directory. This I do not like, and it confuses our clients who connect saying they can see "random folders that aren't mine", or some that think they've "hacked" the server. I really need it so upon connection they go to "username" directory. I can do this by using:
Code:
usermod -d /username username
Which changes the users home directory to "/username", and then upon connection it works just fine, they are taken directory to their home directory. However, I really really do not like the fact that "/etc/passwd" shows a different home directory to their real home directory, i.e it states "/username" when actually it is "/home/username".I've spent the entire day looking a different ways of doing it, and I can't come up with anything.

I don't know how to fix this command:
Code:
sudo chmod 700 *
when in the folder some files have the space character in the name. I have this error (sorry, italian version):
Code:
chmod: opzione non valida -- " "
translated is 'invalid option'. I have to chmod any single file with "", but it takes too much time...

I've got some trouble while trying to install some applications on my linux system. It is said that the files in my /var/www/html/xxx directory, where I put them, is not writeable. The command chmod 777 xxx has been tried to make it work, but the error remains when I opened the applications again.
To be specific, I want to install phpFreeChat on my system, so I put those files in the /var/www/html/freechat directory, cd there and typed chmod 777 data/private, chmod 777 data/public on bash. Here's the result of list -al data:
drwxr-xr-x. 4 root root 4096 Jun 17 15:07 .
drwxr-xr-x. 13 root root 4096 Jun 17 15:22 ..
drwxrwxrwx. 2 root root 4096 Jun 17 15:07 private
drwxrwxrwx. 3 root root 4096 Jun 17 15:07 public
These all seemed all right to me, until I typed http://localhost/freechat in my browser. Here's the result:
phpFreeChat cannot be initialized,
please correct these errors:
/var/www/html/freechat/src/../data/private
is not writeable

I've just tried to create my first own live-cd using the instructions here: [URL] With the minimal kickstart I get a weird problem though:
...
Installing: libselinux ##################### [ 81/114]
Installing: psmisc ##################### [ 82/114]
Installing: MAKEDEV ##################### [ 83/114]
[code]....
Notice that "chmod" and "touch" are part of the package coreutils which gets installed only after these commands are used. I'm seeing a similar problem with selinux being referenced before the libselinux package is installed. I can boot the resulting image but after the kernel boots it panics because it cannot find /dev/root which might or might not have something to do with the errors above.

I have set up a home server with ubuntu desktop since im new to this and need the gui. I have no problems with the lamp package or setting that up. My question is, can you setup a ftp server and then connect to it from a windows pc on the same network with a client like core ftp? I want to do this to add files and make chmod a little easier if possible.
