- Hi, I'd like some expert help on serial port access.
-
- I have JUST recently installed Linux AND X11(what a frustration) on my
- 486/33 with some help from some comp.os.linux readers, and I THANK them
- all for all the help they offered.
-
- However, like a novice, I have experienced some problems, which I have
- no idea, how to solve, as well as a few questions on serial connections.
-
- First of all, the questions:-
-
- 1) I have a problem with some commands in Linux. All, or close to
- all of them, work for the root user, but some don't work for
- the non-root user. For example, the commands 'uptime' and 'w'.
- I've asked someone and he suggested the following thing:-
- (my 'w' and 'uptime' command -et others- are in my /var/bin
- directory.)
-
- chown root.mem /var/bin/w
- chmod 2755 /var/bin/w
-
- It didn't work at all, and so I was wondering what mistake I
- made, and how I am to correct such a frustrating problem?
- Or generally speaking, how do I correct a problem of that nature?
-
- 2) Related to (1), the w command produces empty 'JCPU','PCPU'
- and 'what' columns, and that someone told me to recompile
- the server(I think that's what he meant, but I could have
- mistaken) or get gettyps204 from tsx-11.mit.edu(which I
- did). Now the question is, how am I to recompile the
- package? Firstly, do I just simply download the whole
- gettyps204.tar.Z file directly to my floppy(i doubt), or
- do I uncompress and untar the file into a temp. directory
- and then download it to my floppy? I hope these aren't
- stupid questions, coz I've been scanning the FAQ for some
- time and it's taking a toll on my eyes(talk about major
- eyestrain.. :( ).
-
- 3) When the root user does a 'elm' command, everything works
- properly, but when a non-root user does the 'elm' command
- the system keeps on displaying a "You have no password entry!"
- and then it throws the user back to the prompt. What is
- going on wrong? Have I forgotten to do something during
- the process of installing the Linux system?
-
-
- That's 'bout all for the questions, so I hope someone can help
- me with the aforementioned problems. Much appreciated.
-
- Now, to the serial connection stuff.
-
- I'd like to be able to allow people to login remotely to my
- terminal server, or at least allow myself to login from remote(via
- modem) to my terminal server. Now the point here is that, I've read
- the FAQ, and quite frankly, it didn't help me much since it didn't
- go into detail with serial connections. Right now, my modem is
- on COM1(which is /dev/ttys1, I think *) and I did try out what was
- suggested in the FAQ; that is, add the following line to my /etc/inittab
- file:-
- ttys2:vt100:/etc/getty -m 1200 ttys2
-
- but I changed it to:-
- ttys1:vt100:/etc/getty -m 9600,2400,1200,300 ttys1
-
- Now that somehow, got the modem's attention, in a sense that, when
- there IS a RING(someone is dialing in), something does happen. I would
- get these wierd messages being displayed to ALL of the consoles. The
- problem is, that the modem wouldn't actually CONNECT. It would just
- sit there, and start looping back with wierd messages like:-
-
- Dec 21 02:07:27 login[33]: invalid password for `RING' on `ttys1'
-
- and some other kinds of junked up responses. From what I figured
- is that the system keeps on asking for the login pass as well as
- the password for linenoise and `RING' and other stuff...
-
- So, it all BOILS down to, HOW do I get a proper connection? I've
- tried the Kermit approach, but I could never get out of Kermit. So
- could someone help me with this? Much appreciated. I know I kinda
- droned on, but heck, I figured background information might help
- experts pinpoint the exact problem.
-
-
- Thank you for your attention, and any help is appreciated.
