Hi Dotan,

Long time without contact. I pasted your words into the shell. It just
returned to my , steven@Yeshua:~$

What happens if I have a connection? Does the audio make a pinging
sound, do bells ring, flashing lights, pretty girls come on the screen,
what? I am not connected though, am I.

That was the reason I wanted to try crossover. My old box has terrible
mount problems. It functions but will not make a fish or Samba
connection. I have need to move a lot of data from the old box. When
finished I will format and fresh install and correct the mounting
problems then. I have about 250gb to transfer, so I need a pretty fast
connection. Do you know if using a crossover is faster than Samba or
fish? If it is, it might be worth the extra trouble. And I am giving
the old computer away after I get the data transferred anyway. Thank
you for the help.

To connect: fish://bob@192.168.1.100 (depending on name and IP
address) of computer you want to connect to.

It is a good explanation, Dotan, I will have to study it a bit; I am
getting some pretty good help right now, so I am going to relax a bit
and allow people to help me. I usually screw up when I start getting
stressed, and this stuff is really confusing to me. A little easier
each day though. I expect to really understand the process by the time
the problems are resolved. Thank you for your help. I really think
this thing you are doing is a real benifit to the community of Linux
users. I know we all will appreciate the result. To me it is, the
impossible made easy. Perhaps a good title for a tutorial.

A crossover cable won't help you fix your mount points.

Steven, can you please run this commands on your old box:

sudo mkdir /storage1
sudo mkdir /storage2
sudo mount /dev/sda5 /storage1
sudo mount /dev/sda7 /storage2

and then, on the new computer open dolphin and type this in the address bar:

sftp://192.168.0.100/


Now, go into /storage1 and /storage2. Your files *should* be there.
Just copy them to whatever place you like in your new computer.

Regards,
Norberto

Hi all,

bc folds (LF/CR) right after the 68th char or so, when working with
large numbers. is there a way to avoid the folding from within bc? (I
know I can use c=$(echo $a |bc -l) ; echo $c |sed 's/ //g' as a work
around) - but if this could be done from within bc, that wud be
nice..!


$:> a=0; for i in `seq 1 1000`; do a="$a+$i^$i"; done
$:> echo $a |bc -l

We have come to sort of an impass. We haven't been able to make a
functioning connection either by using fish or Samba. The closest we
have come is just now I have one computer showing detail from both
computers for the first time. What it shows is not particular pleasing,
but at least they are communicating. I had already posted regarding
crossover anyway, before this breakthrough.

Additionally, I am interested in knowing the crossover technology. One
thing I have not received an answer for is this, which of these
processes transfers data faster. For now I am only going to use this
capability one time. I have about 250gb of data to move and a person
anxiously waiting in the wings to get my old computer.

Once the data is moved, I will be giving the computer to him. I won't
need the ability again until I fix the on/off switch on my laptop. Then
it will again be useful. You seem to know all the ways to transfer the
data using a network. I would also like to know the different ways. It
is no more complicated than that. If it is an abuse of the Lists time,
I would rather not do it, but if not, anyone who would like to know
these things too, can peek over my shoulder and experience the learning
process with me.

Yes, I didn't even know it existed. It is a new term for me.

I looked for .ssh in my /home directory and did not find it. Where do I

I just make the folders known_hosts and ssh but install them where?
/home/steven? /home/?

I want to connect from my old computer to my new computer. I have about
250gb of not backed up data to transfer.

I notice you have your username included like an email address. I did
not do that when I tried to get fish to work, I did this:
fish://192.168.0.100/storage1. Perhaps that is my mistake. I have no
knowledge to draw from, this is a new experience. Thanks for the help.
I need to take a break for a few minutes. I will return to your
instruction in a bit.

A crossover cable is just a normal Ethernet cable with pairs 1-3 and
2-6 crossed.

Both cables give you the same speed, unless your nics are 1Gbps and
your router/switch is only 10/100Mbps.

Nope. Your users are the same in both computers (steven) and so you
can omit "user@" in the connection.

I noticed you want to connect from the old box to your new one. The
instructions I sent are the other way around. Connect to your old box
from the new one. Read them carefully.

There is no crossfire technology. The changing of the wire's location
is an artifact, not a technology. It's still ethernet over cat5. Those
are two terms that you can google if you want to know more about the
