Closing open ports

Hi,
$ uname -a
SunOS kite 5.10 s10_72 i86pc i386 i86pc
I installed Solaris 10 on an spare Dell box recently. I'm not well versed in Solaris and I wanted a little more exposure to it. Over the past couple of days I've managed to shut down just about every service I don't use/need, but I'm left with a few nagging open ports that I can't seem to close. The only port I want to have open is 22 for ssh.
Here's a list of currently open ports (as reported by nmap):
PORT STATE SERVICE VERSION
22/tcp open ssh SunSSH 1.1 (protocol 2.0)
111/tcp open rpcbind 2-4 (rpc #100000)
898/tcp open http Solaris management console server (SunOS 5.10 x86; Java 1.4.2_06; Tomcat 2.1)
6000/tcp open X11 (access denied)
Port 111: Stopping bind (hence closing port 111) prevents X from starting upon reboot. The boot process won't start the dtlogin screen, and I end up having to use console mode. Is there a way around this?
Port 898: This port is opened by the wbem service. If I disable wbem, the Solaris Managment Console won't work anymore. Is there a configuration option for the SMC that allows me to shutdown the listening port but still allows me to use the SMC from the localhost?
Port 6000: I have no idea how to close this port. I did manage to close port 177 (XDMCP) from the Xconfig file, but I don't know how to close 6000. I don't need any remote X connectivity at all. Any ideas?
Thanks.

Thanks for the reply, Bob.
But you can control wbem (port 898) by changing the
file /etc/rc2.d/S90wbem to /etc/rc2.d/s90wbem. So on
reboot it won't start. To turn it off now just enter
from the root prompt "/etc/rc2.d/S90wbem stop" (w/o
o the quotes). I'm not sure about rpcbind.Yeah, I was able to stop the wbem service permanently by toying inside rc2.d, but without wbem, the Solaris Mgt Console doesn't work anymore. I kinda like the Console, but in my opinion it shouldn't be listening for remote connections; there should be an option to allow its use only on the localhost.

I am looking around at how Solaris 10 handles these
services. If you enter the command "svccfg" you'll
be dropped a "svc:>" prompt. From here you can enter
"list" to get a listing of the servcies you can
manage through this tool. Of course you will want to
look at the man pages, svccfg(1M). Two other tools
to look at are svcadm(1M) and smf(5).Let me know if you figure out how to use the svc tools to point to a new daemon. For example, I installed OpenSSH 3.9.p1 at /usr/local/sbin/sshd but couldn't find a way to coax svcadm into starting the new daemon instead of the Sun SSH daemon. I ended up adding an rc2.d script to start OpenSSH, and executing svcadm disable ssh to permanently stop the Sun version. There's gotta be another way...

Closing open ports - using firewall

Have everything set at the most strict settings at my mac book pro, however, came across this link and they suggested several ports where still open. Can or should they be closed? How?
http://www.whatsmyip.org/ports/security/

The OS X firewall that Apple provides is very basic. If you want the very best Unix IPFW firewall to block most all of ports then use the very powerful IPFW GUI application NoobProof. This application use the built-in IPFW Unix firewall in OS X that is stronger than anything you can buy.

Listing and closing open TCP ports

Hi,
For security reasons I would like to have as few open TCP ports as possible on my iMac, leaving open only those that I feel are worthwhile having enabled. How can I go about to
a) identify which TCP ports are currently open on the system
b) identify the processes that have opened the ports and understand the origin and purpose of those process
c) disable the processes that have ports open, if I feel that there is no good reason for having them open
I'm running OS X 10.9.4.
Thanks!
Fredrik

You can run "netstat" in the Terminal or maybe Network Utility to see open ports. However, all you should really do is make sure you don't have any sharing services enabled. Otherwise that is all you can do. Macs are not meant to be used as servers or in secure environments. They are strictly consumer machines. Apple has engineered them to be highly secure, but not configurable by the user. It is highly unlikely that any modifications that an end-user can make would do anything other than reduce security.

Open ports in zones

I am encountering a strange behavior in new zones created using zonemgr 2.0.6 (this is the only way I create zones, so I do not know if the issue is more general). When I create a new zone, two strange things are happening:
1. Immediately after the zone is created, no services are running, not even ssh
2. About 10 minutes later, a whole bunch of services are running. Most of these are not running on the global zone.
For reference, nmap output on the global zone is the following:

The Leopard OS X firewall is application based and not port based. Honestly, I haven't played with it enough to know for certain how to answer your question.
But... when you do connection sharing, you're essentially doing a port based NAT for the systems on the other side of your Mac. This pretty much keeps you from initiating anything to the other system even without a local firewall unless you were to configure port forwarding.
As for blocking packets, you would need to use the 'ipfw' command to do things at the port level.

Help open port on ASA5510 (version 8.3)

Hi all,
I configured ASA to open port 21, 3389, 5900 (outside access in) but when i check port just success : 21 and 3389, Error: 5900
If i configured with only one port 5900 or 3389, is't ok, i don't undesrtand what 's the problem?

Open port issues with Direct Print functionality

Hi, I have been fighting with HP call support about the Photosmart 7525 printer.
Originally I setup and had performed all the functions to enable both web support and WIFI.
Within an hour the printer would not respond to wireless communication, though it had its wireless indecator showing it was connected.
I was told by HP support that the issue will be resolved in March, as there will be a firmware update to fix the issue.
Now that I had the printer install the new firmware I still get the issue.
Though I found through some sniffing, that there are a number of ports enabled and open that are over and beyond print requirements.
Funny thing I can send my printer into instant lockup with all lights flashing with a simple UDP ping sniff. I would think I can do this with other new HP printers using Eprint functions. I will find HP web based printers that are open for public printing and test my theory that HP Eprinters are open to hacking and denyal of service attempts. My Hp print app on andriod list three in my area, and one is at my local Walmart. This would be cool to find this, as I am usually not the first to point such matters out.
I assume some are for Apple devices to print.
Here is my sniffing report:

OK now I am able to run a full scan on TCP ports without causing a lock up of the printer.
I found that having the printer connect to a router that has been setup to use channel 5, 6 or 7 will cause port scanning issues with the printer.
It is obvious that there are 18 ports that are seen as open, whether they are used or not. Two of which are active but have no service connected to them. Some are just dead like port 25, but over half are active enough to recieve data and lock network connectivity within the printer.
As the firmware states some other laser jets may be affected depending on how the configuration can be set.
I moved my routers channel to channel 1 as it is the only other option I have in a highly congested location. It is not as good as channel 6, but the printer seems to have channel 6 locked in for direct printing.
Here is the latest full scan with UDP enabled, it is the furthest and most complete scan I am able to complete, with UDP ports enabled. The TCP port scan has a bit more and I have placed a simple list below the information given here:

Firewall in 10.5, how to open ports and how to manage?

I am pulling my hair out with the new firewall in 10.5. In 10.4 I could just set ports as I liked in the control panel, in 10.5 there is no such thing.
I need to for example open port 49999 to allow PageSender to function in my network.
I need to open port 5901 to work with JollyFast VNC, as port 5900 is used by Apple Remote Desktop and the conflict if they both use the same port.
Some of these ports I need permanent open like 59999 and others for one session and than close again, like 5901. Again in 10.4 I made the rule in the pref pane, ticked the box and Bob was your uncle. Now?
I would like to be able to see what ports are open and active on the machine. I have no idea as to where I could see this.
And at the same time I would like to keep the firewall as closed as possible as I am often on line in hotels etc.
So I need help, is there a manual somewhere someone is aware of? Or do you have any answers?

The new Application Firewall does not work in the same way as IPFW (the main firewall in 10.4).
Instead of managing ports, it simply controls the access of applications to any port. Thus, if you want PageSender to receive connections, you simply need to switch the firewall to "Set access for specific services and applications", and then add PageSender to the list, with "Allow incoming connections". When you do this, PageSender will be able to receive connections on any port that it needs to.
If you don't like this method of controlling connections, you can still use IPFW. Apple has removed the GUI, but you can download a GUI application like [NoobProof|http://www.hanynet.com/noobproof> or [WaterRoof|http://www.hanynet.com/waterroof/index.html], and you can then set access for specific ports.
There are no problems with using both IPFW and Application Firewall.
Cheers,
Rodney

Open port 916/udp not closeable

A nmap scan from the Internet (WAN) against a Cisco RV120W shows an open port 916/udp. This port remains open even if one writes an explicit access rule for the firewall.
A quick googling shows that this port is probably used to access the firmware of the router from the outside as well as it has been involved in security problems some years ago. See http://osvdb.org/show/osvdb/34520
How can this port be closed?
Michael

Dear Michael,
Thank you for reaching the Small Business Support Community.
I would first suggest you to upgrade to the latest firmware release version 1.0.4.10;
http://software.cisco.com/download/release.html?mdfid=282981372&softwareid=282487380&release=1.0.4.10
If nmap still shows the port opened, I then suggest you to disable the remote management to determine if this is the root of the problem, then contact the Small Business Support Center to have a TAC engineer figure this out;
https://www.cisco.com/en/US/support/tsd_cisco_small_business_support_center_contacts.html
Please do not hesitate to reach me back if there is anything I may assist you with.
Kind regards,

Default LaunchDaemons and open ports?

I recently have written a port scanner for a project at my university and after running it, I discovered that a large portion of my Macbooks' well known ports was open.
These were 21 (ftp), 22 (ssh), 23 (telnet), 53 (domain), 79 (finger)!!, 88 (kerberos), 512 (exec)!!, 513 (login), and a bunch of others (see picture below for open ports - afterwards entered @ grc.com).
I checked, if they are reachable from the internet (see picture below). They were not, but that does not say a lot(?), because if someone wanted to make a bot out of my Mac or collect data from it, this person could contact a C&C server from my machine and start communicating without opening any port of the NAT router, as the router allows bidirectional communication if started by the client(?).
I checked, if these ports are reachable from within a local network, by requesting the services behind them from another computer running Linux. And they are! Everyone within the Non-VPN networks of my university was and is able to fetch personal information from me over fingerd! To prevent further leakage, I will block any incoming connections from now on.
> finger user@{Macbook's IP}
same output as when running locally
> finger user@localhost

No Mail.
No Plan.
I am able to login to the Mac via telnet over the LAN, etc.
I checked the configuration of my firewall. It is/was activated. Signed software is allowed to accept incoming connections. Cloaking is not activated and I am not blocking every incoming connection. There are five services in the list below, they are all from Apple. I can not remove them. The minus button is grayed out.
When I ticked 'Block all incoming connections', the services behind the ports were no longer detectable/reachable from the LAN, but the daemons are still running on the Mac!
So my question is, why are these daemons running?! Why on earth is the fingerd running or exec?! This seems not normal. Who has started them (software or person)? I strongly limit access to my computer. I always lock it, when leaving it unattended. I use NoScript in Firefox. Never do I open attachments from mails.
I checked the Mac of a friend with my PortScanner (in his LAN and on his Mac) and his has none of the ports open mine has.
I have not checked my ports/firewall for a long time, so I can't remember if those ports were closed at any time before.
Meanwhile I will read something about launchd, to gather more information.

I'm not an expert on this, but I'm not certain what you are concerned about. All messaging in unix systems is done through ports, and so a variety of ports need to be open for normal system operations. OS X out-of-the-box probably strikes a balance between convenience and paranoia - ports that might be more secure closed left open by default so that novice users aren't driven out of their wits - but I can't imagine that it leaves open anything that constitutes a true vulnerability. Or if it does, you should file a bug report.
I'm told every med student suffers from hypochondria at one point or another, and I know that every comp sci student will sooner or later have a short freak-out over security. So take a deep breath...

Can't open port 80

I just can't open port 80 on my AEBS n 1st G. I want to use this port to enable access from the internet to my Mini server's wiki pages.
I've added port 80 in the "Port Mapping" tab of Airport utility under "personal web sharing", but when I check the port with the network utility, it remains closed.
What am I doing wrong. Please help.
This is the data of the mapping tab in Airport utility:
Public TCP port: 80
private IP address:10.0.1.201
Private TCP port: 80
rest empty.

Sorry for not replying sooner, I was out of town.
I did the setup as you showed it, tested it and it still doesn't work.
I also contacted my ISP with some questions about the port 80 being open or not. Their answer is that port 80 is always open as that's the port used to access the internet (made me feel like my question was reeeaaaally stupid...). I explained I had found some info on the internet that said the Zyxel modems very often come with the port 80 closed, and that nearly made them laugh... :-(
So I once again did a scan of my public port and get this:
Port Scanning host: 200.124.48.xxx
Open TCP Port: 21     ftp
Open TCP Port: 53     domain
Open TCP Port: 554    rtsp
Open TCP Port: 3900   udt_os
Open TCP Port: 5009   winfs
No port 80 in view.
I also did a traceroute of the Dyndn'ssed domain I want to access on my server and get this:

Just so you know: GTD is my ISP.
I can access the same domain locally with miniserver.local/groups/essai/calendar/ very well.
don't know what else to try.

Why does port scan show an open port for application I've never had?

I don't currently and never have used Bacula to backup my Macbook, but for some reason when I do a portscan it often shows a Bacula file daemon being open on port 9102. It also comes up in Netstat as listening, even with my firewall blocking all unnecessary connections, sharing turned off (all), and an Airport ex in front of it also secured. I also cannot find any related files etc. on my machine after a thorough search. Despite my best google and support searches, I couldn't find anyone with the same problem. Is this reason for concern? Either way why would it be there despite it not being ever used on my Mac? I am not well versed in networking, only know enough to get myself in trouble, so thanks in advance for any help.

Ok, I ran a port scan on 9102 and it show it's not responding, but assigned to (bacula-fd)
So what it appears to be is Bacula ( a legitimate program) uses this port, much like Screen Sharing uses port 5900, not necessarily that it's installed on your machine.
It's not uncommong to have open ports, it's so if you ever install the program or use a service it can gain access through the Firewall. You can change that of course to close up everything except certain ports for certain programs.
Now that the firewall is App based, if you don't have the app listed, how do you deny it access?
Well if the program isn't installed on the machine, it can't respond if the port is open or closed.
Simply enable your Firewall and allow the programs you do have and want to access your machine to connect in the Advanced settings.
There is also NoobProof and WaterRoof if you need a GUI/simplicity to enact more complex features of the command line firewall. Block IP addresses and everything. However read up before you mess around, Apple has everythign set up nicely and there are very few successful attacks on Mac's.
If you don't know what your doing, you can actually do more harm opeing up your machine to poential attack.
If your more paranoid, then install LittleSnitch, it's a outgoing firewall and notification software with pop-up window to allow/deny on a per program or request basis. You'll be quite shocked how much is going out in the background without your knowledge.

Mac OS X Leopard Firewall/default open ports rpcbind?

Hi,
I'm looking into hardening/securing mac os x leopard and noticed that port 111 rpcbind is open. Is rpcbind open by default? What are leopards default open ports on a fresh install?
Also is there any way to run openbsd/freebsd PF firewall?
Thanks!

This is what nmap reports:
Starting Nmap 4.76 ( http://nmap.org ) at 2009-03-02 12:28 EST

Not too sure what netvenuechat is and I have no idea why NFS is open/running. I'm not connecting to any NFS shares. How do I lock everything down?
Any suggested IPFW rules?
Here is what 'ipfw show' returns:
3300 36 2160 deny icmp from any to me in icmptypes 8
65535 866558 351141790 allow ip from any to any

Opening port 51325 on firewall

Hello,
In order to get a fast response when the print properties are asked in Office, port 51325 has to be opened on the firewall. After some research on the web I still can't find any reason why...
Anyone knows what this port is used for? Are there any security issues?
Thanks in advance!

Thanks in advance!
Can you provide information, links, etc., where you got this information that Office requires this specific port number? Also, is the port# you're referring to a TCP or UDP port?
FYI, TCP & UDP 51325 is part of the dynamic port ranges known as the Service Response Ports, or also known as the Ephemeral Ports. They are ports that are randomly selected (Windows Vista, Windows 2008 and newer operating systems) between
TCP & UDP 49152 - 65535. In Windows 2000, 2003 and XP, they were 1024-5000. Windows NT used the whole range.
The initial port may be an attempt for Office or any other app, that needs access to something else, such as a mapped drive, or sending something to a printer. The initial port may more than likely be an RPC call on TCP 135, but the response from the destination
host will be a randomly generated ephemeral port. And once the session is closed, the port is dissolved.
Here are more specifics on ports in an AD environment:

Couldn't open port com

HI,
I am using LabVIEW 8.6 to
control an pump through USB (computer) to RS-232 adaptor (pump side) using
COM 4. The first time the VI runs fine. But After I quit the VI, and
restart the VI. The pump does not respond to the initialize command. Another program (from the manufacturer of the pump) reported that it 'couldn't open port COM 4'. Did I miss anything in
closing the com port or in the initiation the com port. My VI is
attached. Thanks.

Open up MAX (measurement and automation explorer) and look under 'Devices and Interfaces'.
You might want to check that the equipment is still assigned to COM 4. If so, it should say:
COM4 ASRL4 (blah blah blah) Settings
It may have been assigned to a new com port if you unplugged and replugged in the equipment.
If it is still COM4, please post the code for the subVI you mentioned earlier so I can take a look at what is going on in there.
