Hi mack_guy911 :)
They write:
« Is this a security improvement? No! In fact disabling ICMP can only cause problems. There is no known bug in implementation of ICMP handling on current versions of major operating systems including Microsoft Windows. There is no sensitive information provided by standard ICMP handlers and thus it has no security impact to leave your machine response to ICMP correctly. »
Totally stupid. >:(
The purpose of the ICMP is to inform network administrator of some events in the network: Local network AND Internet ...
Let's talk about Internet since it's not a safe place compare to a home LAN (I'm not discussing corporate LAN here.)
One of the best protection against malicious attemps against your computer is to keep it stealth. Stealth means that your computer never give any feed-back to unsollicited packets of any kind and this included ICMP Types/Codes.
With a stealth computer the IP address corresponding to this computer is "mute" : is this an IP used by a PC or not? There is no possibility to have an answer ... No feed-back answer to unsollicited TCP, UDP. IGMP, ICMP. Period.
A PC responding to an unsollicitated ICMP actually provided to the source of this packet a sensitive information: somebody is there: this IP addr. is related to an active computer.
No bug in ICMP implemetation? Wrong! Here an example: http://kerneltrap.org/node/5382
No impact leaving ICMP respond "correctly" ? What is a "correct" answer please? Any answer to unsollicitated ICMP packets ? Totally absurd!
Heres the correct way to implement ICMP over Internet in your firewall:
Authorise Type 8 code 0 outgoing only (echo)
Authorise Type 0 code 0 incoming only (echo respond)
Authorise Type 11 code 0 incoming only (timeout) used by trace route
Block incoming and outgoing all the other type/code of the ICMP.
PERIOD.
I challenge anybody to prove here that this setup for ICMP cause any problem to a PC connected to Internet. I'm waiting ! :shifty:
Is it true that Matousec is related in some way to Comodo, now a firewall provider and formally a spyware provider... Is it true also that Comodo phone home ?
Don't only focus to leak test: check with packet sniffer what this FW send over the internet. (May be not only ICMP packets...)
I confess I have a very bad feeling about this Comodo / Matousec bunch...
May be I'm wrong but... I'm an "Old Monkey".
When it's too good to be true.. hmmm hmmm... :o

-{ Quote: "Stealth status adds nothing to security, IMO." }-
I agree, on closed ports, no. But when a port is opened (a process/service listening) it may be a good idea to have it stealthted, as it will give a small degree of better protection. But basically you are right, stealthed port with listening process aren't really "invisible". ;)

The fans argument, of course, how could i forget.. My time here is coming to an end.
Why is the fans argument ridiculous: you're saying the firewall i use on XP phones home, not only that, that they used to make spyware !! , and provide no proof. Nothing to do with fans, but with FUD about my firewall installed right now.

Climenole, I have one quick question. If you are such an advocate of "stealth", then why do you suggest allowing some forms of ICMP? Wouldn't that eradicate the argument that if you don't respond there is no pc there? I don't think the non-existence of a computer is quite the point of "stealth" (or shall we use "filtered" or "dropped" since that is a much better and more accurate term).
By the way, I am not a proponent of stealth, and I prefer to return a port closed message instead of merely dropping the packets. However, each approach has pros and cons, and since I am not really worried with any huge DDoS being mounted against my personal computer, I am not going to worry about saturation of my upload bringing down my internet connection. But for those with this problem, then there is an advantage to just dropping the packets, with hope that your CPU and downstream can keep up as well :P .
Cheers,

I´have read your posts about networking and I respect your knowledge and try to follow your advices when you talk about Look´n´stop (the firewall that I use), but "having doubts" and "bad feelings" about comodo doesnt say anything. Others have also said that comodo must be doing something bad because they offer a decent firewall for free, but no one have yet put their money where their mouth is.
Wouldnt it be a breeze for you, with all your knowledge about networking, to find the evil stuff that comodo "must" do? "feelings" and "doubts" doesnt prove anything, every one has them. I have my "feelings" and "doubts" about Norton and FBI, but no one wont believe me because all I have is some internet pages. I would just look like silly conspiracy theorist if I kept on nagging about Nortons connections without any proof.
Please do some sniffing on comodo traffic and report back what you find. When you find it, Comodo will be out of business and you will be famous. No doubt many will start looking at Look´n´stop instead.

There's advantages and disadvantages to blocking different ICMP packets, to what extent depends on some things, Workstation or Server? Networking? Software used?
Matousec boldly mentions "Attacking software is usually implemented to attack services on their TCP and UDP ports directly without checking whether the host is alive using pings.", this is accurate statement, but for instances, LAN attacks, regardless the machines count, PINGs followed by attacks are fairly common from my observations.
ICMP can be taking advantage of, one example is the ICMP Tunneling http://www.phrack.org/issues.html?issue=49&id=6&mode=txt ...
And what about the old +++ATH0 exploit? http://www.securityspace.com/smysecure/catid.html?id=10020
And more ways of being misused, ICMP: Smurf DoS https://services.netscreen.com/restricted/sigupdates/nsm-updates/HTML/ICMP:EXPLOIT:LAN-SMURF.html
And Climenole have already posted URL for others...
Regarding invisibility, I rather have invisibility then visibility, I seen many cases where visibility lead to more curiosity, invisibility however indicates protected / firewalled user, meaning to most, usually a complete waste of time and resources unless user specifically targeted, then more dedication and time can very well be spent regardless.
As for Comodo PF and it's reputation, I have followed back in 2006 the topic 'Is Trusttoolbar Spyware?' on the COMODO forum (follow the the link in Pedro post #21), and I have to say, I'm one of many who believes what's being said by Melih. Melih has to much to loose, and everyone knows, and this is why COMODO being examined on a daily-bases by skilled folks in hopes of bringing COMODO down. If COMODO has ANY unusual activity, we here be among the first to know, and surely by now!!

On the original thread subject, blocking ICMP, I prefer to block everything that's not necessary for normal operation. With some ISPs, echo reply is necessary to keep from being disconnected, primarily dialup and some others that dynamically assign IPs. With these internet services, systems that don't reply to a ping are assumed to be offline and the IP gets reassigned. None of the dialup or DSL services I've used did this, but some do.
There are advantages to not acknowleging your presence on the net. A potential attacker has to determine which of these is true:
1, the IP is unused,
2, the IP is assigned to a system that's shut down or not connected,
3, the IP is in use by a system that doesn't respond.
With the first 2, there's nothing to attack. The time a potential attacker spends trying to verify your existence is that much less time he spent trying to attack it. If you begin with the assumption that no firewall is 100% impenetrable, making it more difficult to determine the status of your system makes sense.
With all that said, ICMP is only one of many ways to determine if a given system is online. Port scans are another. With high speed and static IPs becoming the norm, stealth is not the advantage it used to be. When dialup and floating IPs were the norm, finding a stealthed system was half the battle. With a static IP, you become a stationary target. Being stealthed still serves to hide whether your system is running and/or connected, but your existence is easier to determine. Being stealthed isn't as big of an advantage as some make it out to be but every little bit helps.

1) Yes, I believed it's better for a PC connected to Internet as a "client" to be stealth.
This is possible only with this condition: the PC is a "client" only.
If you have a server installed and runing like a p2p program, stealthing is impossible. This is normal: a server must answer to unsollicitated packets ... (if they are legal/normal TCP packets, in the format required by the kind of server, with the required data format...)
2) The ICMP setup I'm talking about looks in contradiction with a stealthed state.
Your PC is allowed to ping other machines over Internet and received the answer to this ping. This is a sollicited packet. And the PC is still stealth (for the ICMP)...

Those icmp settings are similarly setup as default in my firewall (Outpost), with the exception of Destination Unreachable: in/out allowed and Router Solicitation: in/out allowed. My feeling is that in certain situations such as mine, disabling ping responses is harmless, but maybe it could cause problems on a LAN. Im not sure.

Did Melih FW protect against this Toolbar threat or this leak is not important for him?

IMO, It's better to stealth all the ports as opposed to just the open ones. If an attacker scans a set of ports and all but one or two reply "closed", it's the ones that didn't reply that will draw their attention. That kind of configuration suggests that they're open, with just a software firewall in the way. The mixed results not only draw attention to the open ports, the unique pattern can serve as an easy way to identify your system, almost like a signature.

I still have the same bad opinion about Comodo and their strange mix of spyware and security products.
I was sorry for the user mack_guy911 NOT FOR YOU OR MELIH or any Comodo believer.
"Drive Consumers to your website" ...
"When a customer conducts a search using the TrustToolbar Search Box, you have the opportunity to drive that customer to your website by registering Elite Keywords. Customers entering your Elite Keyword will be driven directly to your website (or even a deep content link to a specific page within your website)."
http://www.trusttoolbar.com/advertisers/index.html
This is a spyware made by Comodo. Like to be "drive" by Melih stuff ? Go ahead and have fun.
Put that in your pipe and smoke it.
Bye.
P.S.
Funny question for your "insight" :
Did Melih FW protect against this Toolbar threat or this leak is not important for him?
;)" }-
When all else fails, bring out the "fan" argument. How typical. ;D
I trust you are relying on your own biases and interpretations (as is the case with everything else you've said about Comodo so far) on selling to others that Comodo produces spyware. To be honest, I'm more willing to take the word of a major security management systems company that the software is safe, over the disgruntled rantings of a competitor's employee.
So let's see: no concrete proof about the firewall, try to cast FUD on firewall by drawing attention to another piece of software, about which there is no concrete proof either. A job well done, Look n' Stop Expert... not.
Put that in your pipe and smoke it.

The same poeple produce a spyware toolbar and a firewall.
This is correct to ask question about this strange combination of opposite activities. I'm very skeptical...
Also you may (try) to insult me as much as you wish.
I don't care.

Since having evidence to prove your words is obviously not on your list of priorities when you open your mouth, why not just go all the way and say the firewall is spyware? ;)

I think unfounded accusations have been made on both sides... -{ Quote: "But I'll say no more, or I too will be promptly blanked by fans of both C & M... as I have been before." }- -{ Quote: "The fans argument, of course, how could i forget." }- -{ Quote: "To be honest, I'm more willing to take the word of a major security management systems company that the software is safe, over the disgruntled rantings of a competitor's employee." }- -{ Quote: "I'm NOT an employee of LnS." }- -{ Quote: "Since having evidence to prove your words is obviously not on your list of priorities" }- ...so, can we agree on the "ping-debate" at least???

I agree with you. I will never use Comodo products because they
are not to be trusted.
As for a Firewall that is free or any free product they are "substandard"
You get what you pay for.
I would rather use paid software than some of the free junk that is on the market.
As I said before on many forums, "I wouldn't touch Comodo products with a ten foot pole"

I do get tired of some members posting info without making any correct checks. Having bad feelings about software is complete bull.
Install and check out software before posting crap.
Comodo trust toolbar:-
HJT reports:- additions of:
192916
Castlecops report:-
192917
Members, do realsie (if you have not already), I am no great supporter of Comodo, I just support facts, not bull.

Hey folks. As I look at the subject of this thread I don't see the work Comodo anywhere. The subject is about ICMP blocking.
While the debate about Comodo is probably endless, it never the less isn't the topic of this thread.
Please stay on topic and also please refrain from any comments about posters.
Thanks,
Pete

My fault, I misread the outgoing for type 8 as incoming, which would not exactly be the same thing :P

I'm THAT member...
I don't trust people who makes simultaneously a spyware AND a security program. I have a bad feeling about this ...

Look at this please instead of saying that I'm a bullshiter: (I trust CastleCops not Comodo)

Hi Climelone
-{ Quote: "Look at this please ......" }-Once again you are posting without checking. This is NOT added with the current trust toolbar, if it was, I would of posted the info.
You are posting old/outdated info.
I am wasting no more time with you.
