    Firewall question...


    I've tried two free firewalls for Windows7. Windows7 Firewall Control and Privatefirewall 6.1. When I do a Shields up scan with Gibson (www.grc.com), both of these report that port 23 (telnet) is open. Is this normal? I have'nt used it for a long time, but if I remember correctly, when I used Zone Alarm pro with XP, GRC would report true stealth on all ports.

    can you explain your problem with some more details and may i know the reason for using such external firewalls while 7's FW is quite strong n AVG's is the best i think.

    I believe port 23 is for telnet.

    Edit..

    Google just confirmed that port 23 is for telnet. So no worries there for you :)

    Telnet should definately not be open. its one of the easiest way to gain access to a remote computer. All you have to do is type "helo" and it will tell you abt the system.

    ZAP, ESET, both stealth all ports on GRC. You have a realtime virus checker runnning?

    I thought 7's FW was quite adequate as well. I use Windows7 Firewall control along with 7's FW as its built to be compatible and eases the set up of the 7 FW. But I was VERY surprised to see GRC say that port 23 was open even with the 7 FW running. I don't think that's good. I may go back and try ZA free since the newest version seems to indicate that it plays nicely with Windows 7.

    I agree with Ken on this one... its like hanging a neon sign on your front door.. "Not home .. Come on in" I use MSE and score a True Stealth on GRC.com btw..

    No reason to have it open. Its not even included in the OS anymore. telnet is a bi-directional com that is easily hackable. Google it and hacking and you'll you see. We make sure FTP is closed, and you wouldn't think of leaving remote desktop without a password so too with telnet.

    Hi Ken!

    I'm using MSE currently (although there is a new beta version of AVAST 5 that has come out that looks like it fixes alot of problems with the first beta that I might try). I was toying with giving Norton Internet Secuity 9 a go (something I didn't think you'd ever see me say after all the days of Symantec "bloatware") but they want $60 for it and I HATE having to pay for a AV/FW YEARLY! May give ZA free a go.

    If you want to have real protection(firewall in this case) you need to use a paid software, not the free ones or worse Windows firewall.
