I use vsftpd, i disabled anonymous users. sometimes i look at the log-files. and there are much entries from bots. they try to connect to the ftp with users like apache or tomcat. they try it 10, 20, 30 or more times. can i block them with vsftpd after 5 failed logins for 1 hour or something like this?

View 1 Replies View RelatedI'm running vsftpd on a Ubuntu 10.4 server and noticed that my ftp server is getting brute force attacked. I usually check for the IP address and manually add it to my Smoothwall firewall but I was wondering if there is a way for vsftpd to automatically block denied access after certain number of attempts. Let's say 5.

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.
Here 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 am getting "530 Login incorrect" error message when trying to connect vsftpd server through ftp.
I have vsftp executable and configuration file recieved from windriver. earlier i was not able to run this executable, but after few changes in vsftpd.conf now i am able to run vsftpd server. But when I try to connect to this server from another system I am getting above error.
When ever i try to login to my ftp server(linux, fedora) through filezilla or cuteftp then its giving error even if login details are correct. Its are working fine locally but remotelly its giving error when ever i try to connect to it using external ipaddres or domainname. the error is as follows Status:
Connected with [URL]. Waiting for welcome message...
Status:Connecting to host1.domain.com ...
Response:220 (vsFTPd 2.0.5)
Command:USER test
But if i try to connect to ftp server via brower(internet explorer or mozilla). ITs working fine.I dont know what is the reson behind this. few days back it was working fine through filezilla or cuteftp. proxy setting are also fine. its the same which i was using few days back.

ie,
USER NAME : LAST LOGIN TIME
I followed instructions from here: [url]
Everything seems to be ok but if I try to login it says following:
I have tried with numerous clients and accounts but still nothing, I cant get past the login. What may be wrong?
Here is the log from account creation, could the last line be causing the problems?
I had some hassle with the last two iptables lines but once I took away RH-Firewall-1 from those lines iptables gave no error anymore.
I changed this: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT
To this: -A INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT
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'm trying to configure vsftpd to just allow my local users to login and be confined to their home directory (and its sub-directories).
Here is my vsftpd.conf:
listen=YES
anonymous_enable=NO
local_enable=YES
[Code].....
I've tried multiple configurations to no avail. I always end up with this same end result.
I'm using VSFTPD on my office LAN for one simple task: to receive-and send - installation images created with Ghost4Linux. Until recently, my main LAN server ran on CentOS, but I decided to migrate it to Slackware (nicer release policy ).
What I usually do is create an 'install' user who can login to FTP, but not on the system. Here's an example of what I used to do on my CentOS setup:
Code:
# mkdir -p -m 0700 /home/ftp/install
# groupadd install
# useradd -d /home/ftp/install -g install -s /sbin/nologin install
# chown -R install:install /home/ftp/install
# passwd install
The relevant bits in vsftpd.conf looked like this on the CentOS server:
Code:
...
anonymous_enable=NO
...
userlist_enable=YES
userlist_deny=NO
userlist_file=/etc/vsftpd/user_list
...
Then I only had to create the /etc/vsftpd/user_list file and put a single line in it to allow the newly created user:
Code:
install Now I've tried to get the same behaviour on Slackware, and I succeeded more or less, except for one thing. There's no way my 'install' user can login to FTP when his default shell is set to '/sbin/nologin' (or '/bin/false'). Only when I change the 'install' users' default shell to a "real" shell like '/bin/bash', he's able to login.
Here's a little practical demonstration of what's happening:
Code:
$ lftp localhost
lftp localhost:~> user install

View 5 Replies View RelatedI'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.

I am running a ubuntu server 10.10 with SSH, and OpenVPN. I use it mainly for the VPN, but I have seen log in attempts such as:

Is it possible to make it so when some one has tried logging in 5 times with an invalid user/pass that the ip is banned for 10 minutes? I have password auth set to no and am using keys.
Is there an ssh or sshd parameter that can be set to block out a user after a set number of attempts tp login ?

About a month and a half ago I purchased two new 500GB serial ATA hard drives from Best Buy to replace my other, very old 186GB SATA hard drive. Since then I've had issues with Linux. Sometimes when it's booting it gives a bunch of error messages, such as "failed to set xfermode," and then it boots. Other times, after INIT has started, I get ext3 errors about failing to read an inode block, then "cannot start /sbin/agetty" and "ID c5 respawning too fast," and at this point booting fails altogether. These errors seem to happen randomly. However, once the system has booted, everything seems to work fine, and there are no further issues.
I know it's not a faulty hard drive or filesystem because I've tried Linux on both hard drives numerous times, and I've reformatted many times, one time I even tried erasing one of the hard drives byte for byte and then formatting it, and still had issues.
I've tried Arch Linux, Gentoo, VectorLinux, and openSUSE, and all of them have given me these problems. The live CD's for Ubuntu 10.04, Clonezilla, and GParted all have trouble partitioning/cloning/installing to these hard drives. At this point, it's obvious to me that there is a universal problem with this particular model.
GRUB and Syslinux both work fine, and Windows XP works fine too. It's only Linux that's giving me issues.
I would rather not buy a new hard drive if I can help it, seeing as these two are almost brand new. Is there some BIOS setting that could be causing these problems? Is it some unsupported feature in the hard drives? Is it a bug in the Linux kernel?
The hard drive model is WD5000AADS. Both hard drives are this same model. My motherboard is an NForce 680i SLI.
EDIT: I've tried ext2/3, ReiserFS, and XFS, and all of them do this, so I don't think it's a filesystem issue.
I woke up this morning to the horror that the ext3 partition on my 1TB drive (the only partition on this drive), in an external USB drive case, was not readable. I did some poking around on Google for related issues, and found that what worked for many was to have fsck check, and possibly fix, some errors that have occurred on the partition. This I did with the following command:
Code:
root@naglfar:/# fsck -y -C -V /dev/sdc1
fsck 1.41.4 (27-Jan-2009)
[/sbin/fsck.ext3 (1) -- /dev/sdc1] fsck.ext3 -y -C0 /dev/sdc1

I found a problem where I least expected it. I cannot use skype on my ubuntu hardy. I install it without a problem, but when I try to login it says: login failed, multiple instances may exist.
After some googleing and several different installations I am still no closer to finding out what is wrong.
If there is anyone with the solution please let me know, and if you need any extra info or command output I will send them asap.
