Can I tell Rsync to wait longer for a password when connecting to a remote system?

[Doug S]

It seemed to work for me. I did it just as a test, but otherwise agree with the comments from the others.
Anyway, I changed the sshd_config file as so:

doug@s19:~/config/etc/ssh$ diff -u sshd_config.24.04.original sshd_config
--- sshd_config.24.04.original  2024-09-02 10:58:17.367097735 -0700
+++ sshd_config 2024-09-03 20:11:45.040473573 -0700

-#LoginGraceTime 2m
+LoginGraceTime 1440m
 #PermitRootLogin prohibit-password
 #StrictModes yes
 #MaxAuthTries 6
doug@s19:~/config/etc/ssh$

And the connection status while the client rsync waits for the password:

doug@s19:/media/backup/backup/rpi3$ ss -o -t
State   Recv-Q   Send-Q Local Address:Port     Peer Address:Port           Process

doug@s19:/media/backup/backup/rpi3$

I'll edit this later with more entries, but it should wait for a day. I tested shorter timeouts already.

EDIT: The above was about 11 hours ago. I entered the password for the waiting rsync command just now and it worked fine.
