I have an embedded system with Debian on ARM. I use ntpdate for time synchronization, but I am not sure whether it supports SNTP.
I have 2 linux box configured with IPv4. I have tried adding IPv6 to them. I have issued this commands on box1:
ip -6 addr add fd32:2d7f:f3c1::1/48 dev eth0
And I get this:
inet6 addr: fd32:2d7f:f3c1::1/48 Scope:Global
Then I have issued this command on box2:
ip -6 addr add fd32:2d7f:f3c2::1/48 dev eth0
Back on box1 (command/response):
ping6 fd32:2d7f:f3c1::1
is alive!
ping6 fd32:2d7f:f3c2::1
ping6: sendto: Network is unreachable
Why doesn't box1 ping box2 (of course, also box2 can't ping box1)?
Is the hostname case sensitive? Is
ping MYHOST
equal to
ping myhost
Does it depend on the DNS used? Are there differences between Win/Mac/Unix systems?
I have a .com file that starts a java software from OpenVMS. Now I need to add the following option to the .com script:
set process/parse=extended
But it doesn't work!
set process/parse_style=extended
java myjavafile
Returns a:
%SKP-DATA: (Records not beginning with "$" ignored)
I've downloaded, with ftp, a file which contains too many .s for a OpenVMS system.
swing-layout-1^.0.jar
How can I remove the extra dot?
I want to let a standard user change the system date.
So I created a named pipe. The standard user write a date to the named pipe and a root process listens to it and sets the date accordingly:
(user)
echo 122515502010 > /tmp/mypipe
(root)
date -s < /tmp/mypipe
Unfortunately this doesn't work. Where am I wrong?
I'm doing this from an embedded Linux (busybox) with bash.
I know that keeping /home in different partitions will preserve my data.
But what about the user-specific configuration files? Are always forward-compatible? Are there other issues as well?
