Hi all, hope I'm not of topic here but had no response elsewhere... we observe a problem with login starting with kernel 2.6. Actually the problem still exists in 2.6.11-rc3-bk3-20050206171922-bigsmp which we loaded from SuSE. We never saw this problem before and we used nearly every release in the past. The problem: When we try to login to a remote machine with telnet or rsh we sometimes fall back immediately with the message 'connection closed'. When we try again the login mostly succeeds. The ratio of bad/good attempts over all is 1/10. It doesn't depend on the state of the machines e.g. type if hardware or load. It happens on laptops as well as smp-machines. In messages we see: "login[xxx]: FATAL: can't reopen tty: No such file or directory" We debugged login and tracked the problem down to the fopen of /dev/pts/nn in function opentty() just after a call to the kernel function vhangup(). The questions: - why does /dev/pts/nn disappear (and never comes back)? - is this a kernel bug? is there something wrong in vhangup()? - is anybody else aware of this problem? (there's only one additional posting from Yehavi Bourvine) - is there a solution (pending)? Thanks in advance for any hint, we are pretty losts...
