New Sguil VM with Client

Hot on the heels of last week's news about the first Sguil VM, I am pleased to announce the release of a new Sguil VM. This new image is a complete self-contained Sguil deployment, with sensor, server, database, and client. The screenshot above shows the Sguil client and Ethereal. Again, you need something like VMware Player or better, and a program to unzip the archive.

The new file is being shared on the Sourceforge mirrors as I noticed this OSDN mirror already has it. The new .zip is 218 MB, and it expands to about 700 MB. The VM disk is 1280 MB (1.25 GB) and it is built with 128 MB RAM.

The new VM is nearly identical to the previous VM. Use the same user accounts, network settings, etc., as previously described. There are two exceptions:

  1. I have added of the Sguil client components. This means you can either connect to the server using your own Sguil client, or log into the new VM as user analyst, run 'startx', and find yourself in a graphical Fluxbox environment.

  2. I have added tools used in my Network Security Operations class, mentioned in this post.

I built the VM using my new installation script described here.

For those who wish to build their own VM, I made the following additions beyond what the script does.

When I first boot the machine, I enter single user mode and create a /boot/loader.conf file with the line 'hint.apic.0.disabled=1'. I still seem to have troubles with time in the VM, although this post seems to indicate the latest VMware combined with 6-STABLE might improve the situation.

I next install Vmware Tools for FreeBSD. This allows a large display at 1024x768. Inside VMware, I follow VM -> Install VMware Tools -> Install. Next, on a local console as root:

mount /cdrom
cd /tmp
tar -xzvfp /cdrom/vmware-freebsd-tools.tar.gz
cd vmware-tools-distrib

If I need to re-run the configuration, I can try /usr/local/bin/

I also edit /etc/motd so the users see the following at login.

Welcome to the Sguil Virtual Machine!

Richard Bejtlich ( created this VM to
help those new to Sguil ( become familiar with
Sguil components and operation.

To start Sguil server components, do the following.

As user sguil, execute these scripts:


As user root, execute these scripts:

/usr/local/bin/ restart

To start the Sguil client, do the following.

Log in as user analyst. Run startx to launch Fluxbox.
Launch a xterm, then run /home/analyst/

Note: Thanks to transltr for pointing out that the motd as installed in the VM says to run /root/ and /root/ That will be fixed in the next release.

The VM as provided uses space as follows:

$ df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s1a 124M 56M 58M 49% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/ad0s1g 62M 76K 57M 0% /home
/dev/ad0s1f 124M 16M 98M 14% /nsm
/dev/ad0s1h 61M 17M 40M 30% /tmp
/dev/ad0s1d 496M 441M 15M 97% /usr
/dev/ad0s1e 124M 24M 90M 21% /var
/dev/acd0 6.9M 6.9M 0B 100% /cdrom

Notice /usr is pretty tight. /nsm is small too. This is a demonstration VM, not a production version. Following my scripts you can easily create your own VM though,

This is VERY cool.

I would like to see some canned data in the db for the true standalone, can't connect to the net demo.
Tcpreplay is on the box. Try retrieving the packet captures from The Tao. Start all the Sguil components, and then run Tcpreplay on the Sguil VM like this as root:

tcpreplay -i lnc1 sf0.lpc

I don't have a ID and password for any ID. I must of miss something. Any ideas what they are?
Do you mean a Sguil client user id? The default is sguil with password sguil.

wow, dunno what i did, but image kept rebooting in vmware 5.5. So went to single user mode, fsck'd everything, ran login, logged in as root, reinstalled vmware tools, started x and saved a snapshot...turns out reboots the image...dunno why I'm not a bsd or sguil guy just thought I'd try it out.
This is

ifconfig $INTERFACE -arp up
# As a daemon
sancp -D -d /nsm/$SENSOR/sancp/ -i $INTERFACE -u sguil -g sguil -c /usr/local/etc/nsm/sancp.conf > /var/log/sancp.log
# In foreground
#sancp -d /nsm/$SENSOR/sancp/ -i $INTERFACE -u sguil -g sguil -c /usr/local/etc/nsm/sancp.conf > /var/log/sancp.log

I've never heard anything like what you posted. What do you mean, the image keeps rebooting? And why do you blame

An MD5 sum for the release being offered would be really nice.

Good idea -- I just posted hashes on the Sguil VM page.

I was doing pretty well for a FreeBSD newbie I think. (figured out that I had to remove the proxy server line from the script and uninstalled an old version of the mysql client because it was conflicting). Then I get the error saying the mysqltcl extension does not appear to be installed on this system. Download it at I downloaded it, but am stuck there. Does anyone have any recommendations about how to install it. I really want to try sguil but just when I think I've got it licked something gets in the way. For any who bother to read this (and heaven forbid, reply), thanks.

Join us in #snort-gui on and ask there, or post to the Sguil users mailing list.

I have been looking for a build such as this. I have not yet downloaded it and have one question. Is the virtual disk built as SCSI or IDE? I would like to run it on ESX but ESX does not support IDE.
It's IDE.

It's easy to build the VM though if you use my script, described here.

I get "Unable to connect to localhost on port 7734" using sguil:sguil to login (SSL not selected) Any ideas on what I could do?
Drop in to #snort-gui on I can't troubleshoot your problem with that little amount of detail.

This image seems to work fine in the workstation environment, at least it started, I haven't played with it enough to figure everything out.

But If I try to bring it up in the ESX environment it won't boot because it needs SCSI drives instead of IDE, or am I missing something simple?

Apparently ESX won't run images built on virtual IDE drives? If so, try building your own image -- that's the answer I gave an earlier poster. It's not difficult.

In the workstation, you can create/add an extra (new) scsi-based vmdk file and then ghost the ide vmdk disk to scsi vmdk and then put/export that scsi vmdk disk to esx server.

One of the other problems is that FreeBSD 6.0 wont install on ESX. The latest official version of FreeBSD that ESX supports is 4.10. I am not sure if Richard's script will function on this old of a version.

Hi Ruy,

SANCP has no concept of alerts. It is not tied to Snort in any way.

I recommend posting this question to the snort-users mailing list:

John Curry, SANCP's author, reads that list.

Dear Richard,

First of all thanks for the work.

When I run the new vmware version on vmware server 1.0.3 build 44356, I get mounting errors.

/dev/ad0s1g: can't check file system.

The same message for /dev/ad0s1f

For /dev/ad0s1d I get:

Then I am dropped to single mode shell.

I hope someone can help.

I am using the KnoppixNSM hdd install which seems to work and is extremely easy to get up and running. However, the one continuous problem that I have is using the tk client (win or uni) because the tcp 7734 socket becomes unavailable.

Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0* LISTEN 4882/mysqld
tcp 0 0* LISTEN 4480/sshd
tcp 0 0* LISTEN 7667/tclsh
tcp 0 0 ESTABLISHED7667/tclsh
tcp 0 0 ESTABLISHED7691/barnyard
tcp 0 0 ESTABLISHED6822/sshd: tmessner
tcp6 0 0 :::3000 :::* LISTEN 7739/ntop
tcp6 0 0 :::443 :::* LISTEN 3535/apache2
udp 0 0 ESTABLISHED3985/tcpdump
udp 0 0 ESTABLISHED4010/tcpdump

I can restart the 'd' server and sometimes it comes back within 10-30min but this is not guaranteed. Often it never comes back resulting the inabilty to monitor events with the client.

This problem is very consistent so I was wondering if anyone else has had similar problems, and if so how were they fixed?
