Help sharing entire drive directory with Samba + Knoppix 5.0

Hey guys,

Im working on recovering files from a friend's laptop that WinXP crapped out on, and decided to try out a Knoppix CD for the first time :). I've connected the laptop to my home network to send files to my SuSE 10.0 machine (my current desktop), so i can save them here and reformat the laptop's NTFS drive. Samba is fully enabled, and I'm currently able to share files between both SuSE 10.0 and Knoppix 5.0.1 machines, but I can only share files or directories that reside within my /home directory on the Knoppix machine.

Theres about 8.5gb worth of stuff that im attempting to recover, and the task is going extremely slow since i have to copy a directory from the /media/hda1 hdd into the /home directory, and share from there...its extremely slow since it seems that any folder larger than 200mb lags extremely hard when copying over and eventually freezes, crashing the entire laptop.

Ideally, id really want to just share the entire /media/hda1 directory, so i can just access it all from my SuSE machine and save everything that i want here, rather than having to manipulate the files on the laptop, wait for the directories to be copied into /home, hope nothing freezes, then finally sharing the directory. Is there any possible settings to change to allow me to share directories that don't reside within my /home directory?

Thanks in advance!!

Just fyi, I am also having the same problem in that sharing a drive that's NTFS via Knoppix (which can be done, I think you just need to engage the LISa server and then you can access the drive... I THINK... I'm a noob and I know when you just turn on SAMBA, it doesn't show up but everytime I configure LISa, it shows up), the transfer of the files off the NTFS drive are 1/2 as fast then off a FAT drive and they lock up and eventually the receiving machine times out / says the machine is not on the network anymore, etc... :(

There's a problem here with the NTFS drivers I think as I've already tried this on a linksys NIC card with the same results.

Also same problem happens in Debian.

You might want to try using sftp as an alternative.

Start knoppix as root by typing: knoppix 2, at the root shell

at the root prompt set a password by typing: passwd

Start the x server type: startx

Start the ssh daemon: k->knoppix->services->start ssh server

mount the drive you want to share, i did it using konqueror.

On your Suse , open a shell and type: sftp [email protected]pix

type help, for a list of commands.

HTH

Thanks Rusty.

I'm personally trying to be able to share the drive with 40 XP PC's via the network neighborhood - any idea on why nfts mounted drives would time out as they are doing?

I haven't tried to fix this, as my networked PCs are inches apart in the same room, but if you're having NTFS timeout probs it's probably bec the default Samba config is setup to mount/unmount the shares periodically. You'll be able to follow this if you start the System Log from the Knoppix->Services menu (I did that from memory, using Windows rite now.) Anyway, you can change that behavior by modifying the SMB.CONF template used by the Samba server script. I simply don't know the precise combination of SMB.CONF options....Jet

Apparently it's not Samba, but no unix in the world will work with NTFS like the way I want. Pushing several 500-700MB files. For small files, NTFS is forgiving under unix but large files = doesn't work at all. Went FAT32 :)

Absolutely not true, at least not in my environment. I've been using Knoppix (5.1-CD) to move files of several hundred MBs from one PC to another all year. In fact, I just did an offload of a few GBs just yesterday. I do downloads off the 'Net (ISOs, movies, etc) on two PCs, but only one has a working DVD burner for moment. For reasons that defy reason, going from XP to XP (to the burner PC) really blows, hence my trial of Knoppix. In fact, the 1st few times I used my ad-hoc Knoppix server, I did MD5 digests to make sure I was getting accurate transfers. I'm sold on it now.

Regarding Samba vs FAT32/NTFS, when I discovered Samba (2.x) several years ago, it didn't work well w/ FAT32 partitions. Big files uploaded during peak server loads == periodic server crashes. Samba 3 is much improved and I haven't seen a single hangup going to/from Knoppix+Samba. Of course, YMMV....Jet

Odd cause I also am using Knoppix 5.1 and it failed on 3 different machines using a NTFS drive. It would slow down/stutter after about 5 seconds of xfer to just one machine... then eventually time out and the WXP machine would claim it could not find the machine on the network anymore.

Could you maybe post your SAMBA file and if I feel crazy enough on day, I can try it again.

Ohh... off topic a little, is there any other network monitoring programs like the one that comes with knoppix that shows realtime data of data xfering across the network - hasn't someone made a matrix style looking data monitor yet? :)

There's little to share but here it is:

It sounds like you're having Ethernet probs, bec the default SMB.CONF
is so simplistic that I can't imagine how its settings would have an effect
on anything....

I may be having an ethernet issue after all. I just hooked the gigabit network up, SAMBA'ed into a PC and am xfering 15gigs of data at a stead 12mbit a second :-|

That's just not right... XP to XP it's running a lot faster then that...

Ugh... I'm thinking it's an ethernet driver issue. It's an on board ethernet gigabit interface and I even dropped a linksys gigabit ethernet adapter in there thinking it would be more standard but same problem exists.... time to do more research... 12mb on a 1000 connection is bad :P
