I have been upgrading to SR10.1 over the last month and have encountered a problem that I can't seem to solve. I can't get telnet logins into an SR10.1 node to work. I hope that this is something that I have done wrong, but I fear that it is a software bug. If so, what can I do about it? I hope that someone can help me. The specifics follow. We were an SR9.7 network a month ago. At that time, I had one machine running SR10.1. Telnet to that machine worked fine then. Then I upgraded the rest of the machines to SR10.1. The registry was completely converted over to my orginal SR10.1 node before doing so and it is now my only registry server for 7 machines. After the upgrade to the other machines, when ever I telnet to a machine (including the original SR10.1 node), it always works the first time after I reboot the machine, but never after that (or at least as far as I can tell, it only works once, the first time I try after rebooting). When I telnet in, I get the machine operating system banner, but the login message never comes up. It hangs at that point and I have to use ^] to get back to the calling machine. After doing this, I do a ps on the machine that I just tried to telnet to and find out that there is a telnetd process still running. In fact, there will be one telnetd for each telnet attempt tried, even if the telnet worked. I have check the /etc/services and /etc/inetd.conf files and they seem ok. The following lines are from those files: /etc/services: telnet 23/tcp /etc/inetd.conf: telnet stream tcp nowait root /usr/etc/telnetd telnetd shell stream tcp nowait root /usr/etc/rshd rshd login stream tcp nowait root /usr/etc/rlogind rlogind exec stream tcp nowait root /etc/rexecd rexecd A possible connection is that sometimes rlogin (or rsh) will, when asking for password, hang when you try and type the password. I have not found a patteren here yet. Does anyone have suggestions as to what might be the problem? If I get several personal messages, I will post a summary to the net.
