About resolving hostname and user transfer
ubuntu server not resolving LAN hostnamesresolving windows hostnameAfter change of host and hostname, terminal won't show itProblem with same hostname and domainall files necessary to change hostname (FQDN)?What are the default settings for 'etc/hosts' and 'etc/hostname'?Hostname conflict between system hostname and apache2 vHosthostname and /etc/hostsAbout the user account transfer on the Linux serverAbout /etc/hosts and /etc/hostname
all the things of my previous user A
directory have been transferred to another user B
directory in the same server.
I even have rebuilt the mpich
. If I run the previous compiled exe or the new compiled exe with dmpar
mode, it will report the following error
~$ ./real.exe
Fatal error in MPI_Init: Other MPI error, error stack:

~$ mpirun -np 8 ./real.exe
ssh: Could not resolve hostname name1.n2.n3: Name or service not known
For the hostname,
~$ hostname
name1.n2.n3
while in /etc/hosts
, it is
IP(xx.xx.xx.xx) name1.n_another.n_another name1
i.e. it seems that only the first word name1
is same.
Does this matter? Since for now I have no sudo
to edit it.
By the way, if I have to login in a jumpserver
first and to 'jump' to my server for now, how to let the X11
still work?
Because it will report the error
Error: Can't open display:
but it is normal before.
