Hello and thanks for tutorial.
I've installed and configured vsftpd. It works in localhost, but when I try connect from another server, it just says "connection time out" I belive that my iptables are configured right, but if not, please tell what I have done wrong.
I would like to have also one user, that have access to all others dirs. And other just have their dirs. And dirs should be on RAID (md0)
VSFTPD config
IPTABLESCode:# 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. # Please see vsftpd.conf.5 for all compiled in defaults. # # READ THIS: This example file is NOT an exhaustive list of vsftpd options. # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's # capabilities. # # # Run standalone? vsftpd can run either from an inetd or as a standalone # daemon started from an initscript. listen=YES # # Run standalone with IPv6? # Like the listen parameter, except vsftpd will listen on an IPv6 socket # instead of an IPv4 one. This parameter and the listen parameter are mutually # exclusive. #listen_ipv6=YES # # Allow anonymous FTP? (Beware - allowed by default if you comment this out). anonymous_enable=NO # # Uncomment this to allow local users to log in. local_enable=YES # # Uncomment this to enable any form of FTP write command. write_enable=YES # # Default umask for local users is 077. You may wish to change this to 022, # if your users expect that (022 is used by most other ftpd's) #local_umask=022 # # Uncomment this to allow the anonymous FTP user to upload files. This only # has an effect if the above global write enable is activated. Also, you will # obviously need to create a directory writable by the FTP user. #anon_upload_enable=YES # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES # # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # # Activate logging of uploads/downloads. xferlog_enable=YES # # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES # # If you want, you can arrange for uploaded anonymous files to be owned by # a different user. Note! Using "root" for uploaded files is not # recommended! #chown_uploads=YES #chown_username=whoever # # You may override where the log file goes if you like. The default is shown # below. #xferlog_file=/var/log/vsftpd.log # # If you want, you can have your log file in standard ftpd xferlog format #xferlog_std_format=YES # # You may change the default value for timing out an idle session. #idle_session_timeout=600 # # You may change the default value for timing out a data connection. #data_connection_timeout=120 # # It is recommended that you define on your system a unique user which the # ftp server can use as a totally isolated and unprivileged user. #nopriv_user=ftpsecure # # Enable this and the server will recognise asynchronous ABOR requests. Not # recommended for security (the code is non-trivial). Not enabling it, # however, may confuse older FTP clients. #async_abor_enable=YES # # By default the server will pretend to allow ASCII mode but in fact ignore # the request. Turn on the below options to have the server actually do ASCII # mangling on files when in ASCII mode. # Beware that on some FTP servers, ASCII support allows a denial of service # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd # predicted this attack and has always been safe, reporting the size of the # raw file. # ASCII mangling is a horrible feature of the protocol. #ascii_upload_enable=YES #ascii_download_enable=YES # # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service. # # You may specify a file of disallowed anonymous e-mail addresses. Apparently # useful for combatting certain DoS attacks. #deny_email_enable=YES # (default follows) #banned_email_file=/etc/vsftpd.banned_emails # # You may restrict local users to their home directories. See the FAQ for # the possible risks in this before using chroot_local_user or # chroot_list_enable below. chroot_local_user=YES # # You may specify an explicit list of local users to chroot() to their home # directory. If chroot_local_user is YES, then this list becomes a list of # users to NOT chroot(). chroot_list_enable=YES # (default follows) #chroot_list_file=/etc/vsftpd.chroot_list # # You may activate the "-R" option to the builtin ls. This is disabled by # default to avoid remote users being able to cause excessive I/O on large # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume # the presence of the "-R" option, so there is a strong case for enabling it. #ls_recurse_enable=YES # # # Debian customization # # Some of vsftpd's settings don't fit the Debian filesystem layout by # default. These settings are more Debian-friendly. # # This option should be the name of a directory which is empty. Also, the # directory should not be writable by the ftp user. This directory is used # as a secure chroot() jail at times vsftpd does not require filesystem # access. secure_chroot_dir=/var/run/vsftpd # # This string is the name of the PAM service vsftpd will use. pam_service_name=vsftpd # # This option specifies the location of the RSA certificate to use for SSL # encrypted connections. rsa_cert_file=/etc/ssl/certs/vsftpd.pem # Added, not in default config: # To get stuff on RAID user_sub_token=$USER local_root=/I/don't/yet/know/where/I/should/mount/my/raid/$USER
Amn... It seems like fail2ban have left some rules from proftpd testing. Should clean them up. :PCode:# Generated by iptables-save v1.4.2 on Mon Jun 28 11:17:02 2010 *mangle :PREROUTING ACCEPT [316760:129808118] :INPUT ACCEPT [265205:125666820] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [129794:34322757] :POSTROUTING ACCEPT [135197:34641445] COMMIT # Completed on Mon Jun 28 11:17:02 2010 # Generated by iptables-save v1.4.2 on Mon Jun 28 11:17:02 2010 *filter :INPUT ACCEPT [10837:8458197] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [143979:35689269] :fail2ban-courierauth - [0:0] :fail2ban-couriersmtp - [0:0] :fail2ban-postfix - [0:0] :fail2ban-proftpd - [0:0] :fail2ban-sasl - [0:0] :fail2ban-ssh - [0:0] :fail2ban-ssh-ddos - [0:0] -A INPUT -p tcp -m multiport --dports 21,20,990,989 -j fail2ban-proftpd -A INPUT -p tcp -m multiport --dports 25,465,143,220,993,110,995 -j fail2ban-courierauth -A INPUT -p tcp -m multiport --dports 25,465,143,220,993,110,995 -j fail2ban-sasl -A INPUT -p tcp -m multiport --dports 25,465 -j fail2ban-postfix -A INPUT -p tcp -m multiport --dports 22 -j fail2ban-ssh -A INPUT -p tcp -m multiport --dports 25,465 -j fail2ban-couriersmtp -A INPUT -p tcp -m multiport --dports 22 -j fail2ban-ssh-ddos -A INPUT -s 192.168.101.0/24 -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 21 -j ACCEPT -A INPUT -i eth0 -j ACCEPT -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -p 21 -m conntrack --ctstate NEW -j ACCEPT -A INPUT -p tcp -m conntrack --ctstate NEW -m tcp --dport 21 -j ACCEPT -A INPUT -p tcp -m conntrack --ctstate NEW -m tcp --dport 22 -j ACCEPT -A fail2ban-courierauth -j RETURN -A fail2ban-couriersmtp -j RETURN -A fail2ban-postfix -j RETURN -A fail2ban-proftpd -j RETURN -A fail2ban-sasl -j RETURN -A fail2ban-ssh -j RETURN -A fail2ban-ssh-ddos -j RETURN COMMIT # Completed on Mon Jun 28 11:17:02 2010
