Re: PuTTY suppress pop-ups.

Use CygWin's ssh for now? Or use VNC to keep your terminal sessions
alive? Putty is a wonderful graphical tool, but it's not clear why you
need the 24x7 operation here.

PuTTY suppress pop-ups.

I'm running putty on a Server 2003 box. Every now and then putty
loses the connection and creates a pop-up to notify me.
Problem is I need the session putty is providing to run 24/7. I'm
using Firedaemon to monitor things and keep putty running but while
that pop-up is there, Firedaemon thinks everything is fine.

Thank you Casper.
I was not aware of that. It seems it is also possible to copy using
tar on the same machine

Re: Can one configure sshd_config to allow only sshfs?

I'm not sure about sshfs, but you can set a user's shell to be scponly
([link]) and they
won't get an interactive shell; only sftp.

Can ZFS really be used to mirror where the receiving end is mounted for
regular use or is this more like the tar method of tunneling the data
into a pipie just using data at a different layer of the stack.

cpio?

The intermediate file can be a pipe :
tar zcf - <dir> | ssh <user>@<target> "cd <destdir> && tar zxf -"

Your cluster size (minimum unit of allocation) is larger at the destination
than at the source.

Because there is a _huge_ deployed codebase out there, there is a
published API which would need significant revision, and making any
backwards incompatible changes to that API is hideously dangerous.
It's also impossible for the client to know, in advance, if the server
does or not support symlinks correctly, and vice versa. The risk is

So use rsync.

If you are using Solaris 10, use zfs pools and send/receive data.

Semi-related to this, I do need to find a way of copying files and
preserving links, like the '-a' option does on GNU 'cp'. I think
creating a tar archive and then extracting it might be one way, but
I'd like to avoid the need to create an intermediate file if
possible.

The default behaviour does nothing at all. You must specify various
options in order to run rsync. The usual one is -a (for archive) and -v
( for verbose if you want to see which files are being transfered). As
he says, -H if you want hard links handled properly. There are many
options so skimming the man page is a good idea.

As discussed already tar and rsync are there for this use.

I would definitely use the tar solution or the rsync solution. Since
it's a relatively small amount of data 'tar' may be easiest.
I live for rsync these days too. I'm not sure rsync comes with
Solaris 10 by default. I've added it via Blastwave or OpenCSW, but
SunFreeware tools is good for that too.
