I would like to know what you do with your BFD data?
when you receive an alert message with IP of who tried to hack your server:
- do you just ignore?
- do you send a message of it abuses for the responsible for IP?
I sent for a long time messages of it abuses, but never nobody answered...
is that normal? when will anybody make something against these people?

flood in FTP and brute force
all day i receved msgs of BFD someone trying acess server, how to stop it, exemple:
Executed ban command:
/etc/apf/apf -d 221.186.164.233 {bfd.pure-ftpd}
The following are event logs from 221.186.164.233 on service pure-ftpd (all time stamps are GMT -0500):

Today I woke up to a couple of emails from people in China and India trying to break into my server. Then as I went to login to WHM I get this message:
This account is currently locked out because a brute force attempt was detected. Please wait 10 minutes and try again. Attempting to login again will only increase this delay.
If you frequently experience this problem, we recommend having your username changed to something less generic.
Are there ways that I can prevent these attacks? I know that the IPs involved are getting banned, but are there any other methods I should be taking?
Over the last few weeks I've been getting emails from WHM stating "x login failures attempts to account root (system) -- too many attempts from this ip"
These emails have been coming in almost hourly and it seems as though somebody is trying to guess the password to the root account and random other accounts.
For now I reduced the amount of failed login attempts to 2 before cPanel blocks the IP.
Is there any other way I can completely stop this person from even attempting to guess my passwords?
For a company I'm working at, two nodes have been brute force attempted through SSH. I've got the logs from both servers in front of me, but could anyone enlighten me of who the ISP is?
ISP: host-80-241-179-30.deltanet.ge
I have a managed VPS and I haven't really ever paid too much attention to the logs until now.
I noticed that the APF logs indicate a 2-5 attacks on my server attempting to log in via ssh. My system allows 10 minutes of log in failure attacks before apf bans the ip.
To eliminate the method of attack, I see 2 ways. One way is to change the SSH port; the second is to only allow ssh via specified ip's.
What are the pro's and con's of both... also are there other ways to eliminate these attacks via ssh?
we're using a subdomain to point to one of our server's IP. (gaming purposes).
And people use this subdomain to connect to the game server.
However, We are going to move to a new server soon with a different IP.
I know, only thing I have to do is change the IP of the subdomain to point to the new server, however I know this will take like 1 to 48 hours to fully work.
Is there a way to force people who's still connecting to the OLD Ip to go to the new IP?
ive just installed bfd on a new server:
[url]
And im getting the following in an email every 10 minutes:
Code:
/usr/local/bfd/conf.bfd: line 26:

/usr/local/bfd/conf.bfd: line 38:

/usr/local/bfd/conf.bfd: line 76:
: command not found
/usr/local/bfd/conf.bfd: line 88:
: command not found
The email is being sent from:
Cron Daemon <root@hostname.com> (replaced hostname myself)
Now i know this isnt r-fx networks support but none of there support options seem to work so i figured id post here considering the amount of users that are likely to be using bfd (or you should be)
Ok, this is weird. What do you do when your VPS was submitted to a brute force attack from the U.S Department of Defense?
The IP Whois and Reverse DNS gives me "DoD Network Information Center", why in the world would they try to force access to a small (less than 20 clients) Canadian host?
And in case you're wondering, they don't seem to have any abuse email address.
How can I force sendmail to ignore it when a user sets the From: and Reply-to: headers for an email, such as a PHP script? I would like to force it so it always uses whatever email I set.
I cannot seem to find how to do this... sendmail config is quite difficult.
I have some windows 2k3 and 2k8 win servers and now i must to protect..

we are running a file sharing service and use lighttpd as a web server
the problem is that in Internet Explorer are some files i.e. .mpg, .pdf
and others opened directly in the browser
so is there a way to prevent this behavior(to force the browser to
download the file) by setting headers (or something else) in
lighttpd.conf?

My VPS support said I could try:
-alternate sshd port
-require key access
-selecting client ip access
-rate limit incoming sshd syn packets per src address
However, I need some help understanding the best way to address these so that these brute force attacks aren't successful.
how to force sending the e-mails of an Inbox to a outside e-mail like yahoo or hotmail?

cpanel :
Howdy,
This is occurring because your server is consistently hitting the maximum
allowed concurrent connection limit, defined by MaxClients in httpd.conf:
[root@part7 ~]# grep MaxClient /usr/local/apache/logs/error_log | tail -5
[Mon Oct 22 13:07:46 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 13:32:03 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 14:03:29 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 14:16:07 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 16:48:36 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[root@part7 ~]#
You will need to adjust this setting to a value which better accommodates your
server to prevent any further downtime.
over the last 2 days I've gotten 11 emails telling me about brute force detections on my server, the vast majority of them are for sshd from different IP's.the number of events ranges anywhere from 11 to 515.

Is there a "Best"
What do you guys recommend?
I have read about the CSF, is this any good?
my server is being brute force attacked at port 22.. It caused my server to be blocked by my ISP's upstream...
at first I follow the instruction on this forum showthread.php?t=456571 (can't post link)
but then I realized (from the upstream email, I don't have access to any log on their side) that it was UDP.. not TCP.. but it was said to be brute force attack on SSH port.
Now all I do is moved ssh port.. and then limit the max connection per minute to port 22/UDP like on the above tutorial page..
Is that enough? I can't use IPTables to permit specific IPs, I'm pretty much very mobile so my own IP is different each time.
Any ideas why UDP attack?
Is it possible that brute force attack turned out to be UDP protocol? cause if it's not, then I think my ISP/its upstream can't be trusted..
We are struggling to configure our Apache reverse proxy (on WIN 2008) server to force https.
We have the cert installed on the proxy server, and it seems to be working but we are unable to force connections to https: and the site is still available via http:
How do you enforce https on the site?
reading read about the .htaccess file, virtual hosts but still having a hell of a time putting it all together
Internet -> SSL -> Apache 2.2 -> HTTP -> web app
I get a lot of messages from CSF about Port Scanning and Bruteforce detection.. Is there a way to avoid all of these attacks ? Because it tries to figure out my clients ftp or pop3 user with several usernames, i.e. administrator, postgres, mysql, httpd, and many more..
I know a little about internet security.. Is it possible to make my public IP of shared hosting untraceable ? Like this one..
Just do a ping to ebay.com or paypal.com and then you will receive RTO message or Destination host unreachable, but actually the site is running well..
My issue is with my code I have it rewwrites my addon domains to the main domain. I have a addon domain exclusion line. But each time I add a domain I have to go in and edit the htaccess. I foresee lots of addon domains in my future.
View 2 Replies View RelatedI am getting a few hundred IIS 6.0 FTP login attempts a second on my windows 2003 x64 server.
We have a Sonicwall TZ180, a full IPS and Firewall in front of the server but I cannot determine a way to block these attacks. I simply have port 25 open to all ip addresses, as I do not know a range of valid ips.
Is there any way to prevent these attacks at the firewall/hardware level? I suspect not, because the firewall doesn’t know if a login attempt is valid or not.
I have enabled IPS on the firewall but doesn’t appear to be stopping these attacks. Is there any way to automatically ban ips that hit port 25 X number of times in a second?
I have apache installed on a box with 2 nics. I've seen how to force the listener to an IP, but the issue is that this box uses DHCP. Is it possible to lock the listener to a network/subnet or to a specific NIC?
View 2 Replies View RelatedI have some instructions written in the .htaccess of root directory for my website. So how to force those rules to apply to all sub directories even if those sub directories have .htaccess that overwrite the rules of the mother .htaccess on the root directory ? For example the root .htaccess deny access to all *.log files, so how to force that rule even if in some subdirectories there is some .htaccess files that allow access of *.log files.
