    wat do u think of this??

    ----------------------------------------------------------------------

    GRC Port Authority Report created on UTC: 2003-11-15 at 22:54:38

    Results from scan of ports: 0, 21-23, 25, 79, 80, 110, 113,
    119, 135, 139, 143, 389, 443, 445,
    1002, 1024-1030, 1720, 5000

    5 Ports Open
    18 Ports Closed
    3 Ports Stealth
    ---------------------
    26 Ports Tested

    Ports found to be OPEN were: 22, 23, 25, 80, 443

    Ports found to be STEALTH were: 139, 389, 445

    Other than what is listed above, all ports are CLOSED.

    TruStealth: FAILED - NOT all tested ports were STEALTH,
    - NO unsolicited packets were received,
    - A PING REPLY (ICMP Echo) WAS RECEIVED.

    but my personal firewall isnt allowin any ICMP watsoever to come in or go out o_O i chked again....

    Well, that's different than the summary you posted above. :doubt: (Oh wait, the summary was just from the NetBIOS scan. Okay, that makes sense. That is blocked okay.)

    What is your network setup exactly?

    You said something about a broadband LAN? Do you have a router on your network?

    the server in the network runs LINUX server and gets connected thru a more secured ISP server
    i use cable internet.
    i hav been seeing the stealth test and they say port 135 is a cause for much havoc worldwide .... and its still open in my comp.
    i dinno a comp with all necessary security softwares still can b so vulnerable... anyway i hav got u guys and i trust and bliv u lot
    waitin eagerly for u all to temme my nxt step

    I'm sorry, I don't understand what you are saying here...

    The list of ports seen open by the above GRC scan is completely different from the ports your netstat results show open on your system, so it really looks like there is something "further out" on the network than your PC. The GRC scan is not going directly against your PC, it is going against some other system, router or firewall.

    What exactly is the layout of your network. What does your PC plug into? And then what does that thing plug into?

    It is open "locally" on your computer as it is for almost all Win2000 and XP systems. But, the GRC scan result shows 135 as closed (it is not in either the open or stealth port list, but it was scanned, so therefore it is closed.) That is still good. You are protected for that by something - LAN router? Server? External firewall? ISP blocking?

    Well, such a computer (one with all patches and updates) can still technically be vulnerable. However, your network configuration seems to be protecting your PC. What we need to figure out is the entire network setup you have there to figure out why those ports "show" open to the Internet even though they aren't open on your PC.

    first of all i must say this site rocks and u guys r awesome really... i appreciate the way u answered my queries thx a lot
    nou i am goin step by step i ran netstat again and chked these open ports
    135,445,1025,1031,2469,44334 (though 1 thing i must say here when i first ran netstat it also gave 4380-4406 and not again though they r comin back... )
    nxt bout the network i am havin is having LINUX server based server. whenever i am goin thru the stealth test the IP trace dun come at all to the network i am havin... but it stops to the ISP server from which my network server is gettin the bandwidth... i hope i was able to make u understand atleast something i hav firewalls and yes the ISP server is the last stop to be scanned in the stealth test as i said... even the IP the test shows isnt mine that i hav on network(which i think is my IP on internet is it??) even i am recognised as some other comp name by trace not by my real comp name
    i hope that my comp is.. i repeat i hope as wat i get frm wat u said and stealth reports.. that i hav my comp well configured NOW but thr mayb some in the network thoz r fallin prey to the casualties
    and ya... its never bad to learn MORE

    It does seem like you have a non-standard ISP connection of some sort... Not that that is a bad thing! In fact, in this case it appears to be protecting you external to your system, and that is a good thing. Since the ports open in the scan are completely different from your open ports in netstat, and because NetBIOS is stealthed and 135 is closed, I will state I think you are protected from some of the most common probes out there. That also is a good thing.

    From all I've read so far in your posts, I don't think your PC is vulnerable from any specific "open port" issue, nor does it look like you have any virus or trojan problems now. I think your system is okay. Until we see some specific problem (some "virus found" or some other exploit alerted), I'd have to guess you are okay.

    My recommendation... You are a new TDS user (at least you are evaluating it, right?), so continue using that for the rest of the period of the evaluation and see if it ever finds any actual trojan files. If you like TDS and want to buy after the eval period, then you ought to.

    Also, keep reading the reference threads people have posted for you. Keep trying to tighten your security and that will prevent you from getting any malware in the future.

    >> again first of all i must thank u...

    We're glad to help you learn and secure your system. :cool:

    >> Tiny Personal Firewall

    What version of Tiny are you running? And, if you know what modules are enabled? (I'm wondering if this is an old version of Tiny, before they added the sandbox to it, or if it is a recent or current version with the sandbox fully enabled. I run Tiny's sandbox-only along side ZAP 4.0)

    >> any free good AT u kno??

    No. There are no good and currently released free Anti-Trojan's. It is one type of product where there aren't good free options available.

    >> hey do i still need adaware?

    Ad-aware and Spybot are mostly interchangable, however, we generally recommend that people run both... The free product version of Ad-aware and Spybot are both excellent anti-spyware tools. They can both be installed and used to run periodic scans, say weekly, at the least. (Run them one after the other not literally at the same time.)

    I still don't understand what this is exactly...

    >> ...when i release the gate for a sec the TCP IP Kernel Driver comes in... and that forces me to format my comp...

    How do you know about this? What product warns you of it and what exactly does it say?

    >> i hav a old version tiny firewall i kno its already updated ... if i download the updated version wat wud happen if i go to install...

    What version is it that you have? It makes a difference to the recommendation. However, if it is an old, non-sandbox version then I don't understand why you'd want to keep it installed if you recently bought ZAP 4? (Tiny's a great firewall, but as I said above, it's not a good idea to run two software firewalls on the same system at the same time.)

    >> shud i download updated then unplug my LAN card and then configure as i did earlier??

    If you are going to upgrade, update deinstall or install a firewall, this is a very good and safe way to do it. Get the download. Unplug. Do what you gotta do deinstall or upgrade wise. Start the firewall. Plug back in.

    about TCP IP kerner driver... its a ICMP packet constantly circulating in our network. it causes real havoc once u let it enter the computer changing a lot in ur system. Tiny personal warns bout it and says that someone wants to send u Kernel Driver do u want it to enter or not... once it enters then u r gone u bcome the affected part of network also. actually i was suffering this till i configured b4 even allowing the LAN card to plug . i had to format 4 times b4 for this matter.
    the version is really old i think 2.0.15A but as its much effective in handling most of the evils and most importantly the kerner driver ICMP packet. i ofcourse can download the latest Tiny 5 version and can update my firewall unpluggin the LAN again..
    as u said u also hav 2 firewalls same as mine the TINY and ZA and i did told u the reasons y i am running the two... the two arent clashing wat u say??

    No, I don't have two firewalls. I have Tiny Trojan Trap and ZAP 4.0. Tiny Trojan Trap has no firewall components in it at all. It is a totally separate product from the Tiny Software people. (It is just a sandbox, and therefore does not conflict with the ZAP software firewall.)

    All I can do is make a recommendation, whether you decide to listen to it or not is your choice. The majority of people will advise you to not run or even install two software firewalls on a single system because of the possibility of conflicts (either seen or unseen).

    The old Tiny firewall is a fine packet filter, giving you good inbound protection and considering that you have some sort of network protection from your provider, you probably don't need any more firewall software anyway.

    Subratam TCP/IP Kernel Driver is part is of your TCP/IP stack, and it belongs there. It handles the icmp protocol, and icmp is not anywhere as dangerious as you think, your just being over paranoid, and its a part of normal internet protocols.

    FYI, there were vulnerablilities discovered in the old Tiny that were fixed in Kerio 2x, and you can still download Kerio 2x from this link. I don't suggest you even touch Kerio 4x at this time, and the most recent 2x version was 2.15
    http://www.kerio.com/dwn/kpf/

    Now your rules are the problem, and from your problems it would seem you need to fix more than icmp. This is a power-user program, and does require the user to have knowledge of tcp/ip protocols. Your just being an over paranoid user that doesn't understand what is going on.

    If you want help with your Tiny/Kerio 2x configuration that can be done, and you can post a screenshot of your rules for others to review. However you are in quite over your head, and maybe a application based firewall would be better for you?

    As far as icmp goes just make sure your not allowing icmp 8 inbound, and I've even attached a example of basic icmp rules.

    the ICMP that is relayed in my network corrupts my TCP/IP kernel driver and in return it infects my PC.. i hav been getting lot of helps from u guys... actually i am keeping TINY only for that it really gets u safe from harmful packets as i am seein its doin effectively... as for ZA i am keeping this coz it keeps me in stealth form once i configure that so that ICMP dun get to come in i will keep one firewall at one time
    i really feel bad Low as u thought that i am not takin ur recommendation... but i hav been listening everything and i will listen always as u all kno much more and i am learning...
    hou can i post the firewall rules log??

    "ts nice to kno nothin than knoin somethin wrong" Well besides your horrible spelling, your have fallen under "Knowing something wrong" when it comes to icmp.

    ICMP cannot infect your pc, there are no icmp connections like tcp as its a messaging protocol.

    If you want people to review you rules you have to take a screenshot of your rules, and make a new post in the Other Firewalls forum. Use alt+printscreen to capture the active window only instead of just pressing the printscreen button, and be sure to save it in a internet friendly format like .gif or .jpg for size. Crop the image where needed, and you might have to take multiple screenshots if you have a huge amount of rules.

    Right now by simply renaming one program on your system I could gain access to the internet with Tiny 2x, now do you want to upgrade to Kerio 2xo_O

    I'm going to quote myself highlighting a few words:
    "If you want people to review you rules you have to take a screenshot of your rules, and make a new post in the Other Firewalls forum"

    You can be helped better with your firewall configuration in the firewall forum than in this generic security forum.

    The rename issue is a bug in Tiny 2x where it can bypass your firewall configuration compeletly, otherwise it wouldn't let it out normally depending on your configuration.

    Kerio 2x was built with Tiny 2x code. Kerio became their own company when they separated from Tiny Software. Its 99.% the same, and will import Tiny 2x rules. The interface is the same with many fixes, and udpates to the program itself.

    Now your starting to listen more, others were being nice to you, but it wasn't getting through to you so that was a problem. I realized you were still learning from what I read, but I also realized that you already had ideas you believed for some reason that you were not changing after you were told they were wrong.

    BTW, stick to one firewall only. Running both will only cause problems.

    I'll be back after a while to respond to your posted ruleset, I usually have to write many paragraphs when reviewing others rules so it takes a while.

    Re-Read my last comment about Tiny 2x rules in to Kerio 2x
    "Kerio 2x was built with Tiny 2x code. Kerio became their own company when they separated from Tiny Software. Its 99.% the same, and will import Tiny 2x rules. The interface is the same with many fixes, and udpates to the program itself."

    Yes, you should make sure you won't connect to other machines, or auto-connect to the internet when you don't have a firewall running.

    I was going to do something, but since you say your networked that is another issue. That makes your configuration more complex, so how is your network setup, what ip ranges do you use for your network?

    Since your not completely reading what others are saying as I'm having to quote my last comments, I will ask that you read, and re-read this thread. Instead of using your exported rules I want you to start out with the standard rule set, and read the instructions completely. Its a starting template with some rules loose so they work, and you will have to restrict them later.
    http://www.broadbandreports.com/forum/remark,8023708~root=kerio~mode=flat#8023745

    So download the Kerio 2x, download that standard ruleset, use print preview to print out only the part of the page that contains the instructions, export your Tiny 2x rules, disconnect your machine from the internet/lan, proceed to uninstall Tiny, replace it with Kerio, import the standard ruleset, start customizing the rules, and reconnect to the internet/lan.

    --We will discuss your configuration problems in Other Firewalls forum in the thread you have already started.--
