Script to email failed Ftp login attempts

Shell Script to search Failed Ftp Login Attempts

This Shell script will search the server logs on daily basis and will email you the Failed Ftp Login Attempts of the day. The ftp logs are saved in the /var/log/messages file as by default there is no separate log file for Ftp in Linux.

Create a file /home/script/failedftp.sh and paste the below code:

#!/bin/bash

#Retrieve the current date

CUR_DATE=`date | awk ‘{print $2? ” $3}’`

#Create a temporary file to store the logs
touch /tmp/out.txt

echo “Failed Login Attempts on “$CUR_DATE”" > /tmp/out.txt

#Search the failed attempts and save in the temporary file

/bin/grep “$CUR_DATE” /var/log/messages | grep pure-ftpd | grep failed >> /tmp/out.txt

#Email the contents of the file to your email address
/bin/mail -s “Failed Ftp Login Attempts on “$CUR_DATE” ” youremail@yourdomain.com < /tmp/out.txt

Save the file. You now have to schedule a cron to execute the file once in a day to search logs. Edit the cron file

crontab -e

and add the following cron job

59 23 * * * /bin/sh /home/script/failedftp.sh

Note: This script will work with Pure-Ftpd server. You will have to edit the search string a bit according to your Ftp server.

How to hide folders to avoid deletion via FTP

Hiding folders to avoid deletion via FTP

It is better to hide tmp/usr/lib/var folders via the conf file(when accessing ftp) so that these folders will not be accessed by the users.

If it is proftpd, find out the proftpd.conf

Add the following to the proftpd.conf file:

<Directory ~>
HideGroup wheel
</Directory>

<Directory ~>
HideNoAccess yes
</Directory>

Enter the directory path near to “<Directory >”, like “<Directory /var/www/vhosts/domainName/httpdocs/folder>”

After modification, restart the FTP.

Ftp error “553 Disk full - please upload later”

Problem: You get the ftp error “553 Disk full - please upload later”, even when the quota of the user has not

been exceeded and the disk partition in which all the user accounts reside (say /dev/sda5) is not full.

Cause: The value of the variable ‘MaxDiskUsage’ in the pure-ftpd configuration file (/etc/pure-ftpd.conf ) will

be equal to or less than the percent use of the partition.

——————————————–

root@ [~]# grep MaxDiskUsage /etc/pure-ftpd.conf

MaxDiskUsage 90

——————————————–

# df

Filesystem Size Used Avail Use% Mounted on

/dev/sda5 144G 59G 78G 90% /

Restrict users to their home directory in VSFTP

Sometimes you may want to restrict users to their home directory while doing FTP. You can achieve this in VSFTP with the

following steps.

1. Open the VSFTPD configuration file “/etc/vsftpd.conf” . Uncomment the following lines.

chroot_local_user=YES

chroot_list_file=/etc/vsftpd.chroot_list

2. Create the file “/etc/vsftpd.chroot_list” and place the user names (one per line) that you want to restrict in that file.

3. Restart VSFTPD to take effect.

# /etc/init.d/vsftpd restart

After this users listed in the file “/etc/vsftpd.chroot_list” will be locked up in their home directory

How to Setup the firewall for Passive FTP

Setting up the firewall for Passive FTP: (APF Firewall)

1.Open your APF configuration file with your favorite editor. This configuration file is usually located at: # /etc/apf/conf.apf

# vi /etc/apf/conf.apf

2. Select a port range to use for the passive FTP connection, and find the line that looks like this:

IG_TCP_CPORTS=”20, 21, 22, 25, 53, 80, 110, 143, 443, 465, 993, 995, 2082, 2083, 2086, 2087, 2095, 2096, 3306?

If this list of ports already includes a port range above 20000, then you can skip onto configuring your FTP Server, but remeber the range listed. (20000 to 30000 would be written as 20000_30000)

3. Add the port range to the end of the line and within the quotation marks(”). Remeber each port/port range is seperated by a comman(,), and a port range between 35000 to 36000 is written as 35000_36000 .

IG_TCP_CPORTS=”20, 21, 22, 25, 53, 80, 110, 143, 443, 465, 993, 995, 2082, 2083, 2086, 2087, 2095, 2096, 3306, 35000_36000?

3. Save and restart your firewall.

To restart your firewall:

/etc/init.d/apf restarts not.

What is FTP?

FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network, such as the Internet. You can use FTP to exchange files between computer accounts, to transfer files between an account and a desktop computer, or to access software archives on the Internet. Keep in mind, however, that many FTP sites are heavily used and require several attempts before connecting.

An FTP address looks a lot like an HTTP, or Website, address except it uses the prefix ftp:// instead of http://.

An FTP Client is software that is designed to transfer files back-and-forth between two computers over the Internet. It needs to be installed on your computer and can only be used with a live connection to the Internet.

How to Wget with FTP

Here are some useful commands to download data from an account which is exist on different server.

wget ftp://username:password@ftp.domainname.com * -r

eg : wget ftp://test:celita0201@ftp.domainname.com * -r

OR

wget ftp://ftp.domainname.com/* --ftp-user=username --ftp-pass=password -r

wget ftp://ftp.domainname.com/* --ftp-user=test@domainname.com --ftp-pass=neHGyxhjr -r

How to Change Your FTP Port

Lately FTP has been a problem for a lot of hosting providers. Especially since the recent influx of Gumblar-related attacks and FTP exploits, some hosting providers are now considering changing their FTP ports as an added measure of security. If you’re on a cPanel server you have a couple extra steps to go through, but it’s a rather easy change.

Pure-FTP

1) Edit /etc/pure-ftpd.conf and look for the following line:

Bind <addr> <port>

Where <addr> is a publically routable IP.  The default example, 127.0.0.1, will cause the socket to bind locally but then this connection won’t serve externally. <port> is the new port you wish to put the service on.

2) If necessary, add the new FTP port to your server’s firewall

3) Edit /etc/chkserv.d/ftpd and change the port, which is the first comma-separated entry to the right of ‘=’ on the line in the file, to match the port you put the service on.

Finally:

/etc/init.d/pure-ftpd restart
/etc/init.d/cpanel restart (restarts tailwatchd/chkservd)

ProFTP

Edit /etc/proftpd.conf and change:

Port 21

Then make sure to test to make sure FTP is working before notifying your users!

FTP error 530 Login incorrect

First of all check which FTP is using the Cpanel proftpd or pureftpd

If it is using the proftpd, do the folowing to fix the 530 error
1. First of all try the /scripts/ftpupdate
2. grep /etc/proftpd/passwd.vhosts (here is the domain username)
3. If it is not present there then grep /etc/proftpd/
4. Check details and cat >> /etc/proftpd/passwd.vhosts
5. Paste the main ftp account details in this file
6. /scripts/restartsrv_ftpserver

Note: please be careful in doing it. If you have specified cat > /etc/proftpd/passwd.vhosts, it w
ill overwrite the whole content.

If it is pureftpd:
Do the above 6 steps
7. Sometimes you need to rum "/usr/sbin/pure-uploadscript -B -r /usr/local/bin/ftpfilter" also
