  • monitor/mon-prmisc.c: Correct print line.
  • shell/Makefile.am: Added new file telnetd.c.
  • shell/telnetd.c, shell/telnetd.h, shell/pty.c: New files.
  • shell/shell.c, shell/cmds.c, shell/shell.h: Numerous improvments:
    • The shell_init has a new parameter 'forever' because in /dev/console you need that this process runs forever but in tcp/ip not. (respawn?)
    • A new task for every session opened trought tcp/ip telnet client. (the chargen,daytime and more are possible of implementation but I ask me if they are necesary)
    • Exit from the session delete the task and when the client fails too.
    • More cmds have been implemented. (very reduced version of these) umask, chmod, id, whoami, rm, cat, ...
    • A reduced line edit has been implemented.

Ctrl-C abort the input,
Ctrl-d in the first position gives EOF (logout).
'\b' and DEL makes the rubout operation.
I think that readline() for every session spents a lot of resources.

  • Property mode set to 100644
