 Posted: Thu Mar 12, 2025 9:46 pm Post subject: Open ports across the network. [tentatively resolved] |
 |
|
I'm running into an interesting problem.
I have a server setup with some daemons and nothing else. I set this up yesterday and have yet to move outside my private subnet.
Here is why.
when I nmap my ports from the machine it presents the list i would expect, but if i do it form any other machine on the net it presents a MUCH different view.
From Naru (the affected machine)
| Code: | Naru$ nmap 192.168.42.2
Starting Nmap 4.62 ( http://nmap.org ) at 2025-03-12 17:39 EDT
Interesting ports on Naru (192.168.42.2):
Not shown: 1705 closed ports
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
80/tcp open http
110/tcp open pop3
111/tcp open rpcbind
139/tcp open netbios-ssn
143/tcp open imap
445/tcp open microsoft-ds
2049/tcp open nfs
Nmap done: 1 IP address (1 host up) scanned in 0.254 seconds |
from Mizuho (one of my other linux machines)
| Code: | nmap 192.168.42.2
Starting Nmap 4.62 ( http://nmap.org ) at 2025-03-12 17:42 EDT

139/tcp filtered netbios-ssn
143/tcp open imap
445/tcp filtered microsoft-ds
593/tcp filtered http-rpc-epmap
2049/tcp open nfs
Nmap done: 1 IP address (1 host up) scanned in 5.474 seconds |
This is actually one of the smaller listings i've seen. I've had port listings from this machine with upwards of 2025 ports open.
Needless to say until I lick this problem I won't be bringing it out of quarantine. Does anyone have any ideas what I could to to figure this out?
I suppose I could just setup iptables to block all those unwanted ports, but i'd feel more comfortable knowing the underlying reason.

Scanned Archie -- ssh port hasn't been changed yet... gives me exactly what I thought it should.
| Code: |
[HOME SERVER-root@localhost ~]# nmap 192.168.2.8
Starting Nmap 4.76 ( http://nmap.org ) at 2025-03-13 01:05 CDT
Interesting ports on 192.168.2.8:

80/tcp open http
MAC Address: XXXXXXXXXXXXX (IBM)

I guess I'd want to know what distro your running. It almost looks like something is starting your services... unless they are just set to start at boot.

I don't mean to hijack the thread but here is what I have:
| Code: | [hako@shebiaruz ~]$ nmap shebiaruz
Starting Nmap 4.76 ( http://nmap.org ) at 2025-03-14 13:18 EDT
Interesting ports on shebiaruz (127.0.0.1):
Not shown: 993 closed ports
PORT STATE SERVICE
25/tcp open smtp
111/tcp open rpcbind
443/tcp open https
587/tcp open submission
631/tcp open ipp
3000/tcp open ppp
6000/tcp open X11
Nmap done: 1 IP address (1 host up) scanned in 0.61 seconds |
I am using Mandriva 2025.0. The port that is intentionally opened include 443 only. The rest of the ports listed by nmap do *not* match with shorewall settings either. Shorewall lists other ports being open for cups, bittorrent, etc. but not the ones listed by nmap. Curiously nmap does not report those as open.
For ports 25,111 and perhaps 631, 3000 (I don't even have a modem), 6000, I suspect picasa (google's picture sharing / uploading program) might be responsible. During the installation of picasa, sendmail had to be installed as a prerequisite, that is what makes me think this way, but I am not sure of course. Is there a way to find out what opens these ports?
Among those that are reported open by nmap, port 587 (submission) scares me most by its name.

| Port 587 is sometimes implemented as the replacement SMTP port; the old SMTP port used to be 25 if I remember right, and 110 was the POP port. I have seen port 631 used by webmin in the past, so that port might be used by a printer administration tool, possibly CUPS. Try shutting down a few of those ports and see if any functionality that you need stops. If you don't miss the ports open, leave them off. At least you will then find out if they are actively being used. You can turn them on when you need them and shut them off when you don't need them; nothing prevents you from doing that, other than your own time and your level of concern. |

You are right, I just failed to see that. I need it for cups.
| Quote: | | Try shutting down a few of those ports and see if any functionality that you need stops. |
When you say shutting down the port, do you mean blocking the port by the firewall? If not, I am not sure how to do it. If that was what you meant, I believe they should already be considered closed because shorewall settings do not indicate that these ports (25,111,587,3000,6000) are actually open.
[paranoid]Is it possible that shorewall is being tricked to not block these ports despite its configuration set to block them?[/paranoid]

| I do not see all that many ports open, and the ports listed are commonly used for real network activity. If your paranoia is that high, turn on a packet sniffer and watch everything that comes by. I do not think that you are being seriously compromised. In the past, when I have monitored network activity, I find software that is trying to access my system all the time - and not getting very far at all. Such processes usually give up when they realize that they are not getting anywhere. |

| Thanks for the expert opinion masinick. I actually don't have a high paranoia, whatever amount I have stems from my ignorance. Your insight was enough to calm it down.

I've identified the open ports in the listings i posted previously and they are all valid for the servers I have set up. I have configured iptables to block all other ports and have lost no functionality.
however I still periodically get the odd nmap readings. I'll get a huge jump in open ports (despite having iptables configured) that stay open for between 5 minutes and an hour before closing again. running a packet sniffer during this shows no activity on any of the questionable ports aside from the occasional icmp ping that is is not acknowledged (due to iptables probably). Below is a copy of the output from one of those scans.
I am running a vanilla install of debian lenny with no 3rd party debs/apps installed. It was installed via the official ISO (the same one that i used to install my laptop which does *NOT* show the same issue)
I'm not planning to use the box for any sensitive data, but I am worried that this issue might manifest on other machines on my network which will carry data that is sensitive. I'm not normally a paranoid man but I do worry when network ports are open for no apparent reason (a throwback to my windows days)
Thank your for your time and assistance.

| Wow, Lord.DragonFly.of.Dawn, that is a huge number of open ports! I don't knowingly ever open or leave open anywhere near that many ports! I would say that in your case you will want to look into closing 98% of those and leaving them closed unless you have a specific reason to do otherwise. |

| Wow. A quick paste onto a spreadsheet produced over 1070 open ports. No ideas, I'm network challenged.

IP Tables won't block the services from starting, but it should block the port scan.
With this many ports open, I would do some heavy duty digging into WHY everything is turned on, and if I couldn't figure it out, I know what I would do personally.
This is one of the things I really like about Arch Linux. Everything is by default, off/not installed. The only things that ever get started are what YOU tell it start by installing programs and turning on the dameons in the rc.conf file DAMEONS list. With that one line and I can tell you what services should be running, and one place to turn off anything I want to disable.
[root@VistaCrusher2 ~]# less /etc/rc.conf | grep DAEM
# DAEMONS
DAEMONS=(syslog-ng hal !dbus network netfs @openntpd @crond @sshd @kdm @cups @httpd)
on this particular system I have ports open for ntp, ssh,
I would definitely thing Gentoo is similar, but since I don't run it, I can't offer many good suggestions, other than if it were me, I'd be figuring this out ASAP.

try closing all the ports you dont need in /etc/inetd.conf |
That's the best suggestion I can think of other than scrapping the system and rebuilding it, which may not be a very helpful alternative. If, by some quirk, someone really has attacked this system and managed to put in a root kit or something like that, then clearing the system may be one of the few workable options. I'd try closing those ports first and see if that solves the problem, then monitor it. |
