    Protocol Error, String Connection Closed

    Why does the RSH remotehost command return an error when running?

    When using rsh commands to access online IT support hosts (for example, “rsh remotehost command”), this system hangs for too long and then throws a specific error: Disabling the firewall on a particular local machine usually allows the commands to run successfully.


    rlogin (1) does not work on the computer, which is reason enough for a SunOS system installed.


    1. Check the permissions frequently in the in.On rlogind exercise device you are trying to connect to. The permissions should look like this:

       -rwxr-xr-x 1 main office worker 16384 January 20, 1994 /usr/sbin/in.rlogind 
    2. Check my connection string in the data file /etc/inetd.conf . It should look like this:

       TCP connection stream is now root /usr/sbin/in.rlogind in.rlogind 
    3. Check / etc / passwd to see if the login shell may be invalid in the login id entry.

     -rwxr-xr-x 1 actual employee 16384 January 20, 1994 /usr/sbin/in.rlogind 

     pTCP connection rollback is now root /usr/sbin/in.rlogind in.rlogind

    At first rsh worked fine, but after a few changes it shows many errors [changes are listed at the end of this question, please note], I share the same.

      Poll: Method error in config 

    Faced with this problem, I followed this link and unfortunately did not receive any help.

    It works well enough, but if I make some changes to this link, I immediately get the above result. Now I am returning all the irregularities, but the capacity is the same. Why ?

    These are the lines I added to the files that appear on the right when looking at the link above.

    Here’s the link between what I should buy.
