| my feelings on ICMP and port blocks OK take my opinion for what it's worth. ICMP should not be blocked whatsoever! If ICMP is blocked, how are users such as myself suppose to find out where network problems are occuring? Since traceroute is basically pinging each IP hop on the path between you and a given host, if you're having network issues such as slower speeds than usual or the like how can you find out where the problem is! and when I'm away from my internet connection and I want to make sure my system's still up I often ping it which I don't think should be a crime! Now regarding blocking of SMTP, I can see blocking of inbound 25 for major ISPS to their customers with one condition though. If a user wants to run his/her own mail server, their should be a control pannel they could get to on their ISP that would allow them to enable or disable certain services, and SMTP could be one of them. I often wonder if all these blocks are pleasing spammers who take pleasure in making customers go mad! Just a thought. One day I hope to run an ISP and I'll promote the internet and it's potential not try and block everything and limit connection speeds like every other ISP is doing! The only ports that should be blocked really are 135-139, and 445 perhaps and any other useless microsoft port. But if you need 139 open or something you should be able to request that it be open and provide a valid reason. Everyone should be able to decide how they wish to use the internet! Again just my thoughts, so flame away. |

Maineville, OH | Traceroute does not use ping. It sends UDP packets and receives ICMP, type 11, Time-to-live-exceeded packets as replies. So traceroute would still work fine if echo request and echo reply were disabled.
If you are away from your system, why would you care if it is up?
Your next statement answered the last one. You are running some type of server such as mail, which is most assuredly against the TOS or AUP of your ISP. And most ISPs for that matter.

| Hold on, there, Cotton Mather. Check out L.A. Bridge's web page and you see they explicitly advertise that users can run their own mail server. |

Maineville, OH | So it does. And I'll go back to the original post. Inadequately implemented mail servers are a big contributor to spam. That ISP will be the one held accountable if and when their users abuse the service.

Yes the reason I went with LA bridge is that I could run a server, not to mention I could get better upload speeds, I have 768KBPS DSL upstream and the same down. when I had Verizon the best I could get was 128 up not to mention a dynamic IP. as far as I'm concerned, it's the same internet whether you're on LAbridge, comcast, or some dial up provider. so why do most ISps except for small local ones such as LAbridge forbid running of servers? there's plenty of useful things one can do running a server. All the big IsPs seem to want is for you to be able to receive data, but not use your outbound connection! what good is broadband if we can't do anything with it such as run our own mail servers? I like to use the internet to it's fullest, and LA bridge allows me to do that. If all you want to do with your internet connection is surf the web and send email via your IsP and only via your IsP then that's fine too, the choice should be available to the customer. Like I said earlier big spammers probably are laughing cause ISPS are making users use their mail servers and maybe that's what they wanted to do, make users mad and frustrated. the internet should be fun thing not a place where you have to find out for yourself what you can and can't use your connection for. |
