CentOS 5 Server :: Vsftpd Not Being Recognized By Sftp
May 20, 2010
I set up my vsftpd server, but when using "sftp servername" it's not using vsftpd but another (what seems like) built-in sftp server. Even when I stop the vsftpd service I am still able to get a prompt to log in. I haven't installed any other ftp servers.
I just installed Wordpress and i am delighted of it, nice peace of software. Even so I have to get running a FTP or SFTP server on my localhost machine. I did installed in my Ubuntu 10.10 the VSFTPD server and generated a RSA certificate file (vsftpd.pem). Strange it is that there is no vsftpd folder under /etc, instead vsftpd.conf file is directly into /etc ... so I have generated also my .pem file into /etc. Anyway I have a lot of trouble adding new users to access this server. I use Filezilla as SFTP client. Please let me know if you encountered such an issue, and what is the solution for it. Downwards is my vsftpd.conf file.
# Example config file /etc/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable.
I need to establish an FTP server- one with VSFTPD & one with sFTP having at least 300 users in both. My question is what minimum hardware configuration should I go for both to have excellent performance.
As a Windows user, I generated a pair of DSA keys from CoreFTP Lite and sent it to a third party that runs an SFTP server. They told me that a valid DSA key needs to have ssh-dsa at the start and the username@systemname at the end. CoreFTP generated neither the ssh-dsa header nor the username@systemname footer. I tried with WinSCP and it didn't generate them either. Is there a difference between how SFTP works between Windows and Linux? If I put a useraccount@systemname at the end of the text will it work? How would the Linux system validate that my system is called "systemname"? If it can't validate, what is the purpose of adding it?
I installed vsftpd server in one of my servers using "yum install vsftpd" command. NFS server is running in the other server and mounted as "/data" in this FTP server. root in FTP server has also root authority in NFS server. All the files and sub-folders under "/data" in FTP server have 755 or 766 mode. Even I modified vsftpd setting to allow root login.
When I login as root to FTP server with FileZilla client, I can see all the file list in root home directory and move to /data directory. I can download any file in a local HDD but I can not download any file in /data directory.
I open "man vsftpd.conf", it says syslog_enable If enabled, then any log output which would have gone o /var/log/vsftpd.log goes to the system log instead. Logging is done under the FTPD facility. Default: NO So I add "syslog_enable=YES" to the /etc/vsftpd.conf, and add "ftpd.* /var/log/ftplog" into /etc/syslog.conf. But there is no log infomation in the ftplog file.
I'm still learning my way around CentOS and linux in general... Using CentOS 5.4
BUT, I used the scripts from HowTo/Chroot Vsftpd and it did not work with the non-TLS script config, but the with TSL worked great. I wasn't sure where to put the vsftpd_virtualuser_config.tpl file but I copied it over when the script failed to find it... to where it was looking.
So I think it's working but my question is, TLS doesn't use port 21 but the script defaults to that port. I'm using FileZilla from an XP machine at work and I'm forwarding all the ports given in the HowTo. So I'm forcing the client to use TLS on port 21 but it hangs on the connection. If I use non TLS I get in but it tells me it requires TSL. I've had no luck with vsftpd in the past and this is my next attempt.
I've only recently encountered this problem with vsftpd when I was creating new ftp accounts. I keep on getting:
550 Access Denied.
on every action I try to do on ftp, no matter what. I've been trying to solve this myself however my attempts have been futile.
The permissions, and ownership have been checked and rechecked tens of times now, so thats not the issue. I've reinstalled the OS of my server twice now, and the problem is still persisting. Heres my config file, this isnt for anon by the way.
Code: # Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # Please see vsftpd.conf.5 for all compiled in defaults. #
I already have this setup working in a debian server but I would like to setup the same in CentOS 5.3. I just copied all the configuration files to the CentOS server but I'm getting the following errors in messages:
vsftpd: nss_ldap: reconnecting to LDAP server (sleeping 64 seconds)... vsftpd: nss_ldap: reconnecting to LDAP server (sleeping 64 seconds)... crond: nss_ldap: reconnecting to LDAP server (sleeping 4 seconds)... crond: nss_ldap: reconnecting to LDAP server (sleeping 8 seconds)... crond: nss_ldap: reconnecting to LDAP server (sleeping 16 seconds)... crond: nss_ldap: reconnecting to LDAP server (sleeping 32 seconds)...
I'm able to connect to ftp as a virtual user. It was also difficult as nowhere mentioned, that it should be done with SSL. Anyway I found the answer and got connection. But now I can't connect to ftp server as system user. It gives me "530 Permission denied", or if I delete the user from the file denied_users, - "530 Login incorrect".
1. Still I can't understand, how I can log in to FTP server with a system user.Also some other questions regarding this matter:
2. My httpd server Apache has a virtual hosts located in "/home" directory.The scripts create users in "/var/ftp virtual_users". Will it cause any problem if I will change them to "/home"? All I need to do with this is ability to have several virtual hosts in one server with separate access to each of them via FTP. And 1 account with access to all files in "/home".
3. In my ftp client I can see the owner of virtual host "ftp" instead of username.
Trying to set up VSFTPD on the CentOS 5 box at work, which is an internal web development server. I'm leaving soon, and all knowledge of or desire to learn SSH is going with me so the other employees will need to be able to access the web root using FTP clients.
Essentially there is no need for special user accounts or privileges, it's an internal server in a tiny company. I've got the LocalRoot set to /var/www/ which I can log in to and read all files via FTP, however despite setting everything to 777 in /var/www/ and below, I still can't get any write privileges on the FTP server.
I am attempting to connect to VSFTPD via Filezilla from a windows machine, but regardless of which user name I use I get a "530 Login incorrect" error. I have tried turning off the firewalls on both the CentOS and Windows side of things with no result. I disabled the SSL/TLS commands in the config file, also with no change. I tried a couple of different FTP clients, but got similar results regardless of which client I used. I have been going over man pages and documentation for a couple of days now, but cannot come up with an answer. I suspect it lies in my configuration, but I got the same results when I reverted my config file back to the original. what else I can do? One other note is that I am attempting to connect via a LAN, at this point I don't care if it works across the WAN as I only intend to use it to upload files to my web server.
I am running FTP server using vsftpd 2.0.5-12 on Centos 5.3 64bit with default settings, annonymous access enabled. Each night new files are created and moved into a FTP subdirectory (/var/ftp/spectra) by a script. The files are owned by a local user/group, not root, and the same holds for the /var/ftp/spectra subdirectory. The new files are not visible via FTP. Only visible are files that were created the same day when I made the directory /var/ftp/spectra. Also files that are created "in place", e.g. by vi, are visible until I change their owner/group. This is the situation when vsftpd is runned as a system service (/etc/init.d/vsftpd start).
When I start the vsftpd directly using the command /usr/sbin/vsftpd (both without or with the configuration file specified), all files are visible and normally accessible via FTP.
I have never had the packaged vsftpd start with the ssl_enable option set to YES. The mysql on those servers works just fine with SSL enabled. After reading there seems to be a different package available on rh5 repo. This server shows up to date with 2.0.5-12.el5_3.1. The rh5 list shows 2.0.5-16_el5 per this:[URL].. My question is, is there a set lead time till adoption of current RH packages or is just random? I have to have SSL_ftp running and didn't want to step out of the repo lists if possible.
How do I turn winbind authentication off or vsftpd. I keep getting these error messages in the /var/log/ secure:vsftpd: pam_winbind(vsftpd:auth): request failed: No such user, PAM error was User not known to the underlying authentication module (10), NT error was NT_STATUS_NO_SUCH_USER.I already tried remarking out different things in the config files. Is it safe to remark out the winbind stuff in /etc/pam.d/system-auth if we are using the smbclient to connect to a Windows share?Why would you want to to use AD to authenticate users for something simple like FTP is beyond me.I merely want it to authenticate against local system users.
Using THIS I was able to get virtual users working via standard ftp. After wrestling with selinux and such I'm able to log in as a user defined in the virtual-users file.
At the bottom is the vsftpd.conf. I can start the server no problem. I've been making edits to it so I'm not sure what's right/wrong at this point in it. I have a snapshot I keep reverting to where ftp works with virtual users and then I start monkeying with it again.
First problem I have is I'm not exactly sure how to test it. If I use WinSCP, I try SFTP and in the vsftpd.log I see:
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 am attempting to configure vsftpd to allow anonymous users to PUT files into a shared incoming directory. This would be like a dropbox for my customers. Ideally, the incoming directory's contents would not be viewable by the users.
I believe that refused connection is due to the PAM configuration for vsftpd.

I have a centos server installation running, and have installed and configured vsftpd. FileZilla works great. I am able to connect and transfer files both ways. I used this just for testing purposes.
What I need to do is get Fling File Transfer working. I can connect to vsftpd with Fling, but that is as far as it goes.Sep 20 11:18:44 ftp vsftpd: warning: can't get client address: Socket operation on non-socketSep 20 11:31:03 ftp avahi-daemon:
I have configured rssh 2.3 with openssh 5.8 on RHEL 5.6 64 bit to restrict the users to scp and sftp. When i try to sftp or scp it gives error connection closed. After long googling tried different solutions like add missing libraries, setuid to rssh_helper. I had full copy of /lib to /chroot/lib and /chroot/lib64 but no success. conf and log files are below for reference.
I've setup vsftpd correctly and it's running fine with local users (in the same LAN). However, when remote users wanna login to the server, it takes more than 1 minute to get in. Users do can login from remote. It just took too long. (It prompted for the username and password very fast.) Since the server is behind a router, I did configure the port forwarding for TCP 20-21. The centos version is 5.3. The vsftpd is v2.0.5.
