Problem: Using dual protocol terminal servers (LAT & Telnet) to login to a DECsystem 5500 running Ultrix 4.1 gives the login prompt twice. If i connect to the 5500 (mickey) I get the initial message and then the login: prompt. I enter my login (krf), and I get the login: prompt again. Only after I enter 'krf' again, do I get the Password: prompt. This is somewhat of a nuisance, since I catch myself typing my password at the second login: prompt, and guess what gets echoed? We have only had the machine for a couple weeks. We just started noticing it yesterday with this problem. Had some folks from Virginia come out to install some application software, while my sys admin was getting DECnet working. Don't really know who caused the problem, only that I think it needs to be fixed. If you watch the activity on the port with 'ps agx', the following is observed. Right after you connect to the machine (and receive the first login: prompt), there are two telnetd processes running on the network port (i.e. p0 or ttyp0). If I type a login name and press return, ps shows that I have one telnetd process and one 'login -h nwunts6' process on the port. Note that nwunts6 is the name of the terminal server. Entering a login on the second login: prompt and the password, gets you logged in an this leaves a telnetd process and a csh process on the port. Looks fine. I don't really know where to go from here. Looking at the manual page for /usr/bin/login mentions that if a username argument is not passed to login (I assume from telnetd), then login with give a login: prompt, rather that a Password prompt. Is this a hint or a red herring? We do have phone support with Digital and I will call them, but they are working on TK70 & tar problem for this machine. Seems that if you want to use the TK70 with tar, your whole system performance (as perceived from network logins) goes to hell real fast. Might just be more telnet problems. Software support claims that it is a hardware problem. So hardware is coming out tomorrow to "fix" it. We shall see. For all you hard core Ultrix types, chew on these. Thanks for any assistance anyone provides. Later, Kevin Fenster Nebraska Wesleyan University krf@wucs1.wustl.edu (I'm trying to get my own email connection)
