Install nTOP for Untangle 8.0

The following instructions work on Untangle 8.0 (x86 and 64 bit) and will provide a working nTOP traffic monitoring environment with the current nTOP 3:3.3-11+b2 package included with Debian 5.0.6 release (Untangle 8.0 Final).

WARNING: If you have no experience with *nix command line environments please do not attempt this guide. Cutting and pasting commands from a 'how to' without a full understanding of the syntax and implications is bound to cause you problems.

Install Process:

1. Backup the original sources.list in case of problems during the install -

Code:

---

cp /etc/apt/sources.list /etc/apt/sources.list.orig

---

2. Add the Debian 5.x Repositories to your server:

Code:

---

echo "deb http://http.us.debian.org/debian/ lenny main contrib non-free" >>/etc/apt/sources.list
echo "deb-src http://http.us.debian.org/debian/ lenny main" >>/etc/apt/sources.list

---

3. Update packages and install the current nTOP build:

Code:

---

apt-get update

apt-get install ntop

---

4. Set nTOP's default administrative password:

Code:

---

ntop -A

---

5. Configure the nTOP monitoring interface:

NOTE: If your inside interface is not eth1, change accordingly.

Code:

---

cd /var/lib/ntop

sed 's/INTERFACES="eth0"/INTERFACES="eth1"/g' init.cfg> init.cfg.tmp

cp init.cfg.tmp init.cfg

rm init.cfg.tmp

---

6. Configure nTOP to use TCP port 4000 for remote connections.

Code:

---

echo 'GETOPT="-w 4000"' >>/etc/default/ntop

---

7. Restore the original APT sources list:

Code:

---

cp /etc/apt/sources.list.orig /etc/apt/sources.list
rm /etc/apt/sources.list.orig

---

8. Start nTOP

Code:

---

/etc/init.d/ntop start

---

9. Configure a packet filter for nTOP.

Note: I'm not going to provide a description on how to do this. Please refer to my original post here.

10. Secure nTOP access from outside the UTM.

a. Browse your UTM at http://ip-address:4000

b. Click "Admin" then "Configure" then "Protect URL's"

c. Enter username "admin" and your password (set in step 5 above) when prompted.

e. Click "Add URL" then "Add URL" again.

NOTE: This will require a username and password to access http://your-ip-ddress:4000

11. If you require internal DNS resolution (in the case of a UTM router environment) be sure to set Untangle to handle DNS resolution using your internal DNS servers rather than your external.

If you experience problems please post.

Any chance we could get the 4.x version?

after step 7 i would advice you add "apt-get update".

I've followed this to the T, however, I still can't access nTop from anywhere but the browser built into my Untangle box directly.

This freaking rocks!!!! Thank you, thank you, thank you!!!! :worship::worship::worship: I have wanted to do this for a while and this makes it quick and easy.

@criccio I suspect you forgot the packet filter rule. You have to do this or nothing but the UT box itself will be able to access the NTOP stats.

P.S. Will NTOP autostart when the system is rebooted? Cause I don't see the command to do that though I'm not as familiar with Debian commands as I am with Redhat ones. I know on Redhat you have to do a chkconfig on type thing to set it to auto-start.

That means you goofed or skipped step 9.

Also, I'll reiterate once more nTop has been known to cause strange issues with Untangle, and it will likely break on upgrade.

Then again, you are in the hacks forum, so that should be understood.

I can be seen that:
In a box where it is installed, started to grow disproportionately disk usage, conclusion: making from scratch , no more hack for me in production box :cool:

nTop is not working fine in versions after 6, so please don't make your box unussable!, it causes segmentation faults, and a lot of services fallen!

About step 2, can we directly give a path to repository ntop.

P.S. Good topic, nice work.
