[Cooker] telnet on 8.2b3 ?????, something very strange
Hi , telnet server, yes I know its a horrible thing and you all hate it as its a security risk !!! Msec lev med (3 ??)kernel 2418-2mdk telnet client functions ,but the server is'nt or maybe is'nt package manager says its installed, This application cant be done with ssh , so its telnet ! I use the telnet server to redirect anything directed at 3 ports on this machine , to another machine behind the firewall This was perfectly functional on 81, and I have the same xinetdd scripts and firewall scripts running Its not a secutrity risk to me !! Could someone tel me how to get round what ever has been added, to disable it My actions so far are to remove both telnet- server and client 122-16mdk and replace both with 122-11mdk which is the version with mdk 81that use to work I have now managed to get telnet to localhost to function, but still left with the xinetd redirects failing firewalls have been disabled on both machines, and have no effect I can telnet to the other machine to the ports that are redirected to from this machinethat works If I telnet localhost 8000 xinetdd should redirect to the other machine on port 8000, What happens is that I get connection refused (errno 111)from the other machine Its as if xinetd is adding something, but what I dont know and cant see on a tcpdump on the ethernet link between machines So far this is the only thing I've found that dos'nt work I can use SNAT in iptables to do something similar, but its a pig to setup TIA BR Richard

Re: [Cooker] telnet on 8.2b3
Oh Leon I'm very sure I'm dealing with radio amatuers (hams), to the majority telnet is new, internet linking of bbs's is also new, and the rubbish ,microblows s/w cant cope with anything later than telnet,, ie winpak In most cases I have ipiptunels in use, that way they can use proto93 which means their tiny minds only have to cope with typing c aplace Thats it 7 characters and a space getting them to login and a passwordoh dear !!! and as for ssh far too complicated BR richard On Sat, 2002-03-02 at 18:06, Leon Brooks wrote: On Saturday 02 March 2002 17:43, richard bown wrote: This application cant be done with ssh , so its telnet !

[Cooker] telnet server manpage pb
It's my day to day. war against indetd ! Fron telnetd manpage : DESCRIPTION The telnetd command is a server which supports the DARPA standard TELNET virtual terminal protocol. Telnetd is normally invoked by the internet server (see inetd(8) for requests to connect to the TELNET port as indicated by the /etc/services file (see services(5)). The -debug option may be used to start up telnetd manually, instead of through inetd(8). If started up this way, port may be specified to run telnetd on an alternate TCP port number. xinetd not inetd -- http://perso.wanadoo.fr/linux_wizard/index.html - L'ambition est l'ultime refuge de l'échec.

[Cooker] Telnet
I have done sereral install of 8.0 beta and have yet to find a place to install telnet client and server during the install. Sure I can add it later but telnet is one of the main stream programs for *nix. Also the groups are nice but there should be an everything button and then let me deselect items. Some people (developers) need to have just about everything install and don't want to go back and install packages each time they do something new. -- Ray

Use openssh instead, frustrate sniffers. You can also use scp for much of what FTP does. If you want access from Windows, get PuTTY and its friend, PSCP.
RE: [Cooker] Telnet message
I know this is a stupid question, but I know someone out there can answer this real quick. Anyway I want to add a message to telnet logins (ie when you telnet to my box I want it to say "Welcome to " after you correctly login). How do I do that? I assume it is as simple as editing a text file. Thanks for all your help. I saw a number of responses to this, but none seemed very concise, so I'll toss in my two cents. To display a message at the login prompt, edit the /etc/issue and /etc/issue.net files. The /etc/issue file is displayed just above the login prompt for users logging in at the actual console of the system. The /etc/issue.net file is displayed just above the login prompt for users logging in via the network (telnet and the like). Be aware, the /etc/issue and /etc/issue.net files are recreated from scratch at boot-up, via the /etc/rc.d/rc.local file. Be sure to comment out the recreation steps in this script. To display a message after a successful login, edit the /etc/motd file. The /etc/motd file is displayed just after a user has successfully logged in, before they receive a shell prompt. To run a program after a successful login, edit the /etc/profile (for all users) or ~/.bash_profile (for an individual user), for all users using the bash shell. There are other such scripts for users of other shells. The /etc/profile script is executed by every user once they have logged in. The "fortune" program can be inserted in this script if you'd like every user to see a fortune. The /etc/.bash_profile script is executed by each user once they have logged in. If an individual user wanted to run a program once he logged in, this would be the place to put it. Once again, the above are only for users using the bash shell. If you're using tcsh or zsh, read the man pages for the appropriate files. Don Head [[EMAIL PROTECTED]] Linux Mentor, LCA, Network+ [1 314 692-1942] Wave Technologies, Inc.

If you use webadmin you can edit which file (yes, there is another way with WU-FTP, but I don't know off the top of my head) will be displayed when FTPing in, usually '.message' or '.welcome' are default, both in /home/ftp/. Good Luck! Mandrake does have fortune, the package is fortune-mod-1.0-27mdk.
