Here's another one for ya, I can ssh into my server from workstationB but when I try to ssh into workstationB from my server I get this error message. @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 55:2e:6a:d8:08:26:7f:cd:f4:1d:36:8f:cf:85:3d:1a. Please contact your system administrator. Add correct host key in /home/diadicic/.ssh/known_hosts to get rid of this message. Offending key in /home/diadicic/.ssh/known_hosts:2 RSA host key for 172.16.12.200 has changed and you have requested strict checking. Host key verification failed. Now it looks like I have to learn about rsa keys and ssh. A point in the right direction would be appreciated. Thank all. __________________________________ Do you Yahoo!? Yahoo!

No offense, but start with reading the error message. Have you recently reinstalled "workstationB"? jrw On Fri, Aug 13, 2004 at 11:09:24AM -0700, scty Library wrote:> Here's another one for ya, > > I can ssh into my server from workstationB but when I > try to ssh into workstationB from my server I get this > error message. > > @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ > @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! > @ > @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ > IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! > Someone could be eavesdropping on you right now > (man-in-the-middle attack)! > It is also possible that the RSA host key has just > been changed. > The fingerprint for the RSA key sent by the remote > host is > 55:2e:6a:d8:08:26:7f:cd:f4:1d:36:8f:cf:85:3d:1a. > Please contact your system administrator. > Add correct host key in > /home/diadicic/.ssh/known_hosts to get rid of this > message. > Offending key in /home/diadicic/.ssh/known_hosts:2 > RSA host key for 172.16.12.200 has changed and you > have requested strict checking. > Host key verification failed. > > > Now it looks like I have to learn about rsa keys and > ssh. > > A point in the right direction would be appreciated. > > Thank all. > > > > __________________________________ > Do you Yahoo!? > Yahoo!

Delete the 2nd entry in /home/diadicic/.ssh/known_hosts It will then ask you to add the correct entry the next time you connect. IF it continues to complain, then something bad could be happening.... -- Rocky McGaugh rmcgaugh at teamhpc.com 785-542-1383 x303
Is this the first time you have logged into workstationB from your server? Are you using keys or passwords or both on your server? hint: /etc/ssh/sshd_config file should let you know If you have logged in before and not changed anything since, it would be unusual to see this type of message. Are both of these boxes local to you and not out on the internet somewhere? -----Original Message----- From: centos-admin at caosity.org [mailto:centos-admin at caosity.org]On Behalf Of scty Library Sent: Friday, August 13, 2004 2:09 PM To: centos Linux Subject: [Centos] ssh problems Here's another one for ya, I can ssh into my server from workstationB but when I try to ssh into workstationB from my server I get this error message. @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
