Linux sudo is working slow after changing the hostname

I have changed my hostname in linux mint and after that my sudo works slow I mean how to change the etc/sudoers back again to work properly or there is anything else that I have to change

Solution

  • you probably need to edit /etc/hosts to reflect your new hostname

    otherwise it tries to find info about it via DNS (and timeouts, most probably)

    look for:

    127.0.0.1  localhost  oldname

    and change to:

    127.0.0.1  localhost  newname

    Of course change only the line corresponding to oldname. Above I gave an an example of a machine which isn't connected to the net...

    Below I give an example of a machine which have an IP:

    127.0.0.1  localhost
a.b.c.d    oldname     <-- just edit that line
