Can someone please tell me if the following is a linux/slackware
bug or a configuration problem.
Ever since I have installed Linux both at home and at work I
have had a strange problem. Sometimes when a user would telnet or
rlogin to the Linux box they would have their connection closed
right away. I have discovered that the nameservers that I depend on
have been flaky for the past few weeks. If the nameserver first listed
in /etc/resolv.conf was down this condition occured. It seems like a
some kind of inetd or telnetd problem in which it chokes and disconnects
if the first listed nameserver in /etc/resolv.conf is down and it does
not know to check the other listed nameservers. A quick fix is to
reorder the nameservers in resolv.conf, but it is enough of a problem to
cause users of a system to get annoyed when they can't get into the system.
Other services such as nfs an gopher are not affected by this. If this
problem is listed in a FAQ could you please direct me to it or let me
know what might cause this problem. I have been a faithful user of Linux
for many months know and have had no problems except this one. Any advise
on this is appreciated.
Configuration of my systems that have had problems:
Linux Kernels - 1.1.18 -> 1.1.61
Slackware Distribution 2.0
Network Cards - NE2000 and 3com 3c509's
Sample of a connection problem:
Foo:~# telnet Bar
Connected to Bar.harvard.edu.
Escape character is '^]'.
Connection closed by foreign host.
