Year later, could still log in with cc number of all ones. Need to dig out Telnet to see if it is still there. https://www.telnetbbsguide.com/bbs/execpc/ Telnet sends username and password in plaintext. This is one reason, a utility by that exact name, may not be available in Linux. First they made it hard to find, then later, may have removed it entirely. Other platforms (my old Mac G4 had it, Windows has it), they still offer it. They offer it, on the understanding that the user understands the risks. The telnet command is used to debug other protocols. You can specify a port number, and debug your news server or your email server with it. What you're looking for in cases like that, is the "login prompt" or similar, coming back from the thing at the other end. It helps prove a server is running on a particular port number. Telnet is less desirable in 2018, for "sessions". It's not for chatting with your mom. Or for entering your Unix password, for the entire world to see. Find a secure version of Telnet, before sending your username and password to any service. Even news servers and news clients have this issue. If you work on port 119 of a news server, your username and password travel in the clear. Your ISP can see them. The NSA can see them. If you use one of the other port numbers, they support encryption of various sorts. That's why in the table here, you have choices. http://www.eternal-september.org/ind...wpage=techinfo "Client Settings Server name: news.eternal-september.org Port : 119 (NNTP) Port : 563 (encrypted connection NNTPS) " If you use Wireshark (a packet tracer), and you're having trouble with your newsserver, switching to port 119 allows you to log all the packets in plaintext. And figure out (as far as your end is concerned), what visible symptoms of brokenness are present. If the thing is working, then you can stick with 563 for normal usage. You can see the low_water and high_water marks on a newsgroup, and compare to the article numbers in your news-rc file. (That's for Thunderbird users who "don't see new articles in their favorite group".) Obviously, you won't be using your "regular" password for this service :-) And in case that isn't clear enough, you should not use the same password for an email service, as for your local logins. If you ever need to debug the email service, the password might end up in the open. It depends on your technical skill, as to how you can hide it, and still debug the service. (I don't have the skillz for debugging over 563, but it's possible.) Paul |
