Hi Dima Thanks for the suggestion, but those commands do absolutely nothing - there is no response and killing the terminal window is the only option. Do you have any particular link for this problem? as all the ones I found on Google point to Logout freezing or freezing after some time, in my case the freezing is immediately after the logon.
Also, if I execute ssh client using the following command: "ssh 192.168.211.10 /bin/bash" then, although there is no usual prompt, the terminal is not frozen and I could type commands like "ls" which will output a list of files in my home directory. This makes me think that for some reason a shell is not executed correctly during SSH logon but I cannot find any reasons why, as everything is correct in passwd and /bin/bash is specified for all users.
