Hello everyone, I seem to be having some strange behavior with OpenSSH and was hoping someone can offer me some insight.
Dell Poweredge 2950 Rack Mount Server Red Hat Linux Enterprise AS 4.0 All updates, kernel and security patches have been applied I have about 50 Red Hat machines on my network, all are configured the same and this machine is the only one with an issue. In a nutshell, if you SSH to the machine sometimes it works, and sometimes it doesn't. Usually, if you can't SSH to the machine you just keep trying and eventually it seems to allow you to connect and once it does it will allow others to connect, for a while, before it dies again. Here is an example of what I mean: [EMAIL PROTECTED] 90 % ssh thera df -lk ssh_exchange_identification: read: Connection reset by peer [EMAIL PROTECTED] 91 % ssh thera df -lk ssh: connect to host thera port 22: Connection refused [EMAIL PROTECTED] 92 % ssh thera df -lk ssh: connect to host thera port 22: Connection refused [EMAIL PROTECTED] 93 % ssh thera df -lk ssh: connect to host thera port 22: Connection refused [EMAIL PROTECTED] 94 % ssh thera df -lk ssh: connect to host thera port 22: Connection refused [EMAIL PROTECTED] 95 % ssh thera df -lk Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 20641788 7711284 11881864 40% / none 2020772 0 2020772 0% /dev/shm /dev/sda3 113534884 32996808 74770744 31% /export/home0 /dev/sda2 113534884 44551504 63216048 42% /export/home1 /dev/sda5 103210940 33640452 64327680 35% /export/home2 /dev/sda8 10317828 146812 9646900 2% /opt /dev/sda7 20641788 78760 19514388 1% /tmp /dev/sda6 20641788 174688 19418460 1% /usr/local /dev/sda9 10317828 299140 9494572 4% var As you can see, it failed 5 times, then it allowed the connection. I've changed network cables and ports and that didn't help, I ran "mtr" but it didn't report any packet loss to the machine. I changed the logging level to DEBUG3 but nothhing is being reported other than "Connection Closed" and "Failed none" messages. Does anyone have any ideas? If you need further information just let me know. Thank you in advance, mike
