After the reboot it is strongly advise that the Microsoft Baseline Security Analyzer MBSA be used to identify and correct common security miss configurations. Each issue should be resolved prior to starting this tutorial. This procedure will determine which Index number Snort is attached too, so write it down as it will be needed several times for testing and final configuration!
The following is a partial example of what might be listed as valid Network Interface Cards. Snort needs to know which Index number is attached to the NIC that is monitoring the network traffic. Note: In the interface switch above -i x , the x will be substituted for the Index number of the monitoring NIC. There should now be multiple packets passing through he CMD window example packet below.
If there is no traffic passing through, then open a web browser and generate some web traffic. Do not proceed until network traffic is being displayed in the CMD window.
Use the Find option in Notepad2 to locate and change the variables below. If all the tests are passed, the following is a confirmation that the Snort configuration file and rules have tested good.
Snort successfully validated the configuration! Snort exiting. Do not proceed until 'Snort successfully validated the configuration!
Now to test a rule. Scrolling up through the output from the Snort configuration test in the CMD window should show 1 Snort rules read as shown in the example below. Once Snort has started with the above command, go to another computer or open another CMD window and ping the interface that Snort is listening on. Output similar to the below should appear in the CMD window if the ping was successful.

Labels: Snort scholarship , Snort Scholarship BASE will not pull any of the sensors like many other people here , but I feel like my problem may be on the snort side. But if I run "snort -v" it starts up just fine. I have a feeling there is some piece of the puzzle i'm missing, but i'm not sure what diagnostics I can do to find it. You mentioned: P ossibilities are : 1. I'm reasonably sure mysql is setup correctly due to the amount of time I spent quintuple checking everything.
I tried clearing the db in BASE and restarting it, but it still did not find a sensor. Number three is possible and I'm not entirely sure how to test that.
I copied over your script and did not make any changes the default eth0 is fine and I didn't bother with a whitelist until i can at least get it up and running , but still cannot get it to launch.
Anybody have any ideas? If you need any more info please just let me know. From your post I am guessing snort is not properly configured. How did you install snort? So if you installed snort from source you can not use that init script to start snort. If that fails, post the error message. I installed word for word from the guide at the beginning of this thread with one exception.
I installed snort It finally dawned on me that installing a different version probably made that script invalid. I did however try and start it manually as you recommended.
I know some other people mentioned they were using 2. Edit: I am actually running this on two different networks one at work and one at home. I'm doing this mostly just so I can really learn it, but it is providing a good practice in action consistency. They are both acting in the same manner. So I'm stuck on setting this up, and not sure what I am doing wrong When I get to the part below, this is where I get hung up Write a script to start snort : The only "problem" with installing snort from source is that we now need a script to start snort.
Please let me know what I need to post or where I should be looking for specific errors. Maybe its unable to use the rules file when its starting? You need to post at least your snort error. The command to start snort would help as well. The error I get is just snort failed to start. Sorry, I'm a little slow this morning, haven't had enough coffee. Perhaps this may have something to do with it. Are you referring to the. I have this line in the. Open a terminal.
Initializing Preprocessors! Initializing Plug-ins! I finished installing base. Only turn this off if the system is not accessible to the public or the network at large. This must be set for BASE to function! Do not include a trailing slash! But also put the preceding slash. Let me first say thank you for the great tutorial. I am hoping some one can help me with a problem I am having installing the ossec wui.
Any suggestions would be deeply appreciated to this ubuntu newbie. Merci Sounds like you do not have apache installed. Try this. Thank you I am missing apache, now when i'm having trouble installing that. Before I get told that google is my friend I've tried: sudo apt-get install apache2 and I get Reading package lists Done Building dependency tree Reading state information Done E: Couldn't find package apache2 Once again all help is deeply appreciated.
Hopefully third time is the charm. Is your version of apache trying to download php instead of running it as a script? What version of base? Not sure what you are referring to initially, or what to check. I'm using base Or does it display a page with an error message?
If the browser can not write the file, that is a permissions problem. Change the ownership and permissions of the base directory so www-data can rw the files. Back on the previous page This is what I am seeing in access.
You asked me to do this previously The directory and files in it should be owned by www-data The directory itself needs permissions of and files in the directory permissions of I don't think file permissions are the issue.
I suspect if the permissions are correct I will still get the below error I reported earlier So I'm starting over and have a dumb question. I've gone through the removed a lot of things and am wondering, at what point is snort installed, now that I have started over? I'm at that point where I am supposed to cp the. I'm also kinda confused on copying the. I uninstalled snort and a lot of other things when starting over It depends on how you install snort. If you install snort form source there is no init.
If you install snort from the Ubuntu repositories an init script is included and there is some additiona automation as well. You can not use the snort init script from the repositories with snort installed from source. Is it obvious where I went wrong? I installed from source and followed the howto. I managed to get this part right the first time. Don't know what I missed the second time around.
So something new occurred. I don't know for sure what got me to this point, but my syslog blew up the other day with mysl errors see below. Obviously I'm in over my head, and I think having a better understanding of how logging works in general, how I can tweak it, etc. I've been toying with iptables logging, where things go, adding an entry to syslog.
So I guess I will see where I ended up. Hi, I'd like to add in a few things. What is wrong? Hello there, i have problem in this command. So I've been playing around with this, and have no issues, until again, I get to the snort script, making it bootable, and then restarting I'm still getting this.
Just a shot in the dark here, but have you tried moving 'then' to another line and removing the ';'? Semicolons act as a terminator, thus the if statement ends after the conditions. I'll play around some more with the code. I had went through it when I posted here. Like I said, I'll go through it again and post my results. I just get this Thanx buddy, Very lucid explanation of the steps to secure with snort.
This is a great tutorial. I'm going to have to install this tomorrow on one of my VM's. I work with Snort on a daily basis and just learning to write snort rules now. It's kinda fun and pretty simple once you get past the fear of doing it. Snort is an amazing IDS tool. I have an issue. I'm running Ubuntu 9. I initially didn't set a password when I did the install of mysql, so I thought that was the reason.
Are you by chance, cutting and pasting? The question mark in the error message may be indicating there is a hidden control character sneaking into the command: use near '? Otherwise, the syntax is correct The question mark in the error message may be indicating there is a hidden control character sneaking into the command: Perhaps try typing the command manually.
That's what I thought too, but I'm not cutting pasting. I'm figuring it has something to do with the fact that it's a VM in Citrix and I'm using the Citrix console.
Here's a screenshot of my screen. I got it. It dawned on me to open up openoffice write and try the ' in that. It works by only hitting it once. So, it's something to do with my terminal not taking the ' on the first time. I have to hit it twice for some reason. Now I'm having another issue. Seems to be the user doesn't have permissions.
Didn't I just grant him all the permissions? If I use the user of root instead of -u snort, it works and says 0 rows affected. Change usr to user. But I still get the access denied for user 'snort' 'localhost'. Okay, you have a snort user on localhost, and it has a password. I'm guessing the saved password is not the intended password. Perhaps an invisible control character slipped in there too? Try typing grant all privileges on snort. Maybe it is just my superstition, but I think gedit is more of a plain text editor, while openoffice is more of a "fancy" text editor.
When you copy and paste into the gnome-terminal, make sure your quotation marks look like the one circled in green, rather than the one in red. That's actually what I did this time. But, I "think" I may have gotten it. I just used a different user instead of snort. So, wherever else it says snort, I used the other user name.
I've got snort running according to ps and am logged into Base. Now it's time to test. So, I have snort running somewhat. When I do a "ps -wef grep 'snort' " I get the snort process, but it increments every second, like it's starting and immediately dying and restarting.
Am I looking in the wrong spot? Excuse me for interrupting, but I have just been having issues with. To this I have made the blunder to report it as a bug in the make project.
Now I've just running make again and it seems to have run smoothly. I've been having great use of this thread! Thanks a lot to the author. Warning: There may be issues in compiling snort! When I punch these two commands in installing Ossec-Hids versions 2. Also with this tutorial, for Ossec the command to add an agent is missing, so when you start Ossec the first time, it tries to start the 80 ip address which doesn't work.
So I found additional instructions on the Ossec-Hids website which I can't get to work either. I'm using this tutorial but I'm installing Snort 2. Newer snort versions use dynamic engines and dynamic preprocessors. So, this is what I've done so far that I think might want to be updated in the tut. I'm going to start testing it now with 2.
But, I have to get back to my real job of testing Snort 2. Hi, I'm new to this. I am confused on where you download this base file to. The error is telling you the exact problem. You need to put the path to where the file is located. Hi abrrymnvette, I see. I have apache installed. Is there anything I am missing? Thanks running 8. I learned a lot about running Snort on Ubuntu.
Your directions throughout this thread helped me with clearing my final hurdles. Awesome , glad it worked for you. Hey Bodhi Ok i am not the best cow in the paddock but I could not get this working on KK Ubuntu I am not that fluent and I was following the instructions.. So instead of going moo I decided to remove it and wait for someone with better knowledge to get me step by step guide Cheers Bodhi Sorry 8it did not work out for you.
Sounds as if you were unable to set up mysql. This guide is a great reference, thanks. I did not read though all 23 pages of posts to this thread, so I'm not sure if my question has been addressed.
