So I have a Scientific Linux 6.3 (RHEL clone so basically the question is Redhat related) machine called "B" (with an extra "A" HDD besides the system HDD) and a notebook with SL 6.3. They are in a /24 IPv4 subnet, and can fully reach each other. **Q**: How can I export the "A" HDD device to the notebook, so that on the notebook I could see the "A" HDD as a device /HDD/? (, and locally encrypt it using LUKS - I know this last encrypting part) The important thing is that I need the connection to be secured (SSL?) so that no one can intercept the data that I encrypt on the notebook. **OR**: is it already encrypted via LUKS? (and an SSL connection between the notebook and the "B" machine would be just an overhead?) - extra: I also need that the "exporting of the device" must be routable over network. **ps.: so the main question is: does encrypted communication needed between the notebook and the "B" machine or are ALL the datas on the HDD already encrypted when leaving the notebook (even LUKS pwd too??)**

I'm trying to set up a samba share to a computer that only I will have access to. I need full access to this computer from my windows machine. I am the only person using either machine, and I need full read/write access to the share. I tried this so far, and I can SEE the folders/files from my windows machine, but I can't edit any of the files. My code will be on the linux machine, and I will use my windows laptop to code on it. 1. My windows username is just my email, let's call it my_email@gmail.com 2. There is no workgroup (it's just WORKGROUP). 3. My linux installation user is "expert" (ironic, I know) 4. I'm using Debian 9 (stretch). Just installed today from: debian-9.4.0-amd64-netinst.iso. Used KDE. Here is my smb.conf (comments removed, print sections removed) [global] ; wins server = w.x.y.z ; interfaces = 127.0.0.0/8 eth0 ; bind interfaces only = yes log file = /var/log/samba/log.%m max log size = 1000 syslog = 0 panic action = /usr/share/samba/panic-action %d server role = standalone server passdb backend = tdbsam obey pam restrictions = yes unix password sync = yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . pam password change = yes map to guest = bad user ########## Domains ########### ; logon path = \\%N\profiles\%U ; logon drive = H: ; logon script = logon.cmd ; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u ; add machine script = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u ; add group script = /usr/sbin/addgroup --force-badname %g ############ Misc ############ ; include = /home/samba/etc/smb.conf.%m ; idmap uid = 10000-20000 ; idmap gid = 10000-20000 ; template shell = /bin/bash ; usershare max shares = 100 usershare allow guests = yes #======================= Share Definitions ======================= [homes] comment = Home Directories browseable = no read only = yes create mask = 0700 directory mask = 0700 valid users = %S [Share] comment = Full Access Share path = /home/expert/Projects/expert browseable = yes writable = yes public = yes guest ok = yes read only = no create mask = 0777 directory mask = 0777 write list = 0777 valid users = nobody, admin, expert, anonymous, my_email@gmail.com When I do ls -ld . on the folder where I want to have full access, I get: drwxrwxrwx 3 expert expert 4096 . I thought by giving it create, directory masks and write lists as 0777 I would give full control to Samba. The last line (valid users) was just a shot in the dark from me (didn't work)

I'm trying to follow this guide to access Samba shares: Ubuntu 12.04 LTS Precise Pangolin: File sharing with Samba. but I'm sure there are many of them. I've had problems with Samba before. In fact in my xx years of life on Linux I have never successfully setup Samba. The steps would be: 1. Update your system 2. Install samba $ sudo apt-get install samba samba-common winbind 3. Configure windbind $ sudo gedit /etc/nsswitch.conf and "wins" to the hosts line. 4. Reboot 5. "Having done this you should now be able to select ‘GO > Network’ from the desktop menu and view your entire Windows and Linux based network." But in my case I just see "Windows network" which is an empty folder and that's all. No shares from windows neither Linux PC's. Can anyone tell me what I'm missing or doing wrong?

Is there a possibility to temporarily share a directory per *Samba*? With *Python 3* i can serve the current directory per *HTTP* using: python -m http.server. I'd like to do the same thing with *Samba*.

I have a Mac (BSD UNIX: I believe that USB devices are mounted at /Volumes. Is there a clever method to ensure that all USB memory devices are shared at a consistent location on the network automatically when they are plugged in? Mac has SAMBA UI:

I have a Raspberry Pi 1 Model B which uses 32 bit Bookworm and have connected it to my network router (a BT hub) via ethernet cable. I want to be able to read and write to all files on the Raspberry Pi from my Windows 11 laptop using the path \\192.168.1.123\example. Currently, my PC can read a couple of files that I set up using Samba from that file directory but I can't see any of the original files not created using Samba or any of the USB Drives connected. How could I make my laptop able to write and read to all the files and drives attached to the Raspberry Pi? I also want any drives I attached to automatically be accessible by laptop so I don't have to change anything on my Raspberry Pi every time I attach a new drive.

This my first question here and bear with me if some info is missing. So, i have this technical problem: I have a Ubuntu Server installed on a Raspberry Pi 4 Model B ( so on ARM ) and i need to do a full backup and upload it on another PC in the same local network ( A Windows PC ). This is the server FS:

| Filesystem    | Size | Used | Avail | Use% | Mounted on      |
|---------------|------|------|-------|------|-----------------|

| /dev/sda2     | 110G | 38G  | 69G   | 36%  | /               |

| tmpfs         | 5.0M | 12K  | 5.0M  | 1%   | /run/lock       |
| /dev/sda1     | 253M | 138M | 115M  | 55%  | /boot/firmware  |
| tmpfs         | 375M | 4.0K | 375M  | 1%   | /run/user/1000  |
| total         | 113G | 38G  | 71G   | 35%  | -               |

I thought of maybe set up a fileshare ( like SAMBA ) on my windows machine and putting the backup there. I never did Linux backups and i don't know how to make one, so some questions: - What is the best way of creating a backup? - I need to backup sda1 and sda2 ? - Best way to port it on another machine with different OS ? - Once i have the backup in hand, with a pristine new SSD, how i import it onto it? Feel free to ask me if you need further info, thanks in advance!

I'd like to set up my samba so that each user has access to specific folders. Some of them for example have home folder on server and those should have access to their home folder, other don't and they shouldn't. I have set [share1] ... valid users = user1, user2 #those users have access to this share ... The result is that only some users have access to those folders, that is good. But when I log as user3 he sees this share1, but cannot access it. How can I make it visible only to some users, so that users that cannot access share don't see it at all? I have found some suggestions to use browseable list = user1 user2 but it doesn't work for me, testparm says that browseable list is incorrect.

Is there a way to force a Linux client to reconnect to a NFS server after it has lost its connection? The client eventually notices the server is back and resumes working just fine. I'm just wondering if there is a way to speed up this re-connection.

In the past I have used Virtual Box which has very good support for sharing a folder on the host with a Windows guest. I am looking for similar functionality for QEMU. The documentation suggests to expose a Samba server running somewhere in the network, or use the -net user,smb=/path/to/folder to start a samba server. I had no luck with the -net user,smb option of QEMU. All it does is starting smbd (which conflicts with another service running locally due to a port conflict). Suffice to say, this is unusable, especially with multiple guests in mind. (For Linux, -virtfs (Plan 9) can be used for easy folder sharing.) Other problems with Samba is that it is not limited to folder sharing, it also does printer sharing, user mapping and whatsnot. All I need is to share one (or more?) folders with the Windows guest. Does there exist an alternative folder sharing method for QEMU that works with a Windows guest? Or is there a way to configure Samba to restrict itself to a very limited set of features and integrate it into QEMU? It should: - Not everyone in the network should be able to access the folder. - local users included (if feasible). - Not provide other functionality (printer sharing). - Use case: expose a git directory to Windows, compile it in Windows and use Linux for analysis. - Have an acceptable speed, Windows uses virtio-scsi and virtio-net. - Be able to share a folder from a Linux host with a Windows 7 guest.

When I set the vol size limit in /etc/netatalk/afp.conf, Time Machine initially reports the correct amount of available, but fails on backup and reports that 0 KB are available. I am wondering if this might be because I have a share pointing to /data and another (Time Machine) share pointing to /data/mbp_time_machine. The [netatalk docs](https://netatalk.sourceforge.io/3.0/htmldocs/afp.conf.5.html) specify that "you MUST NOT use this volume to store other content when using this option", but I do not know if they are referring to the AFP volume or the actual logical volume on the host. Below is my afp.conf:

;
; Netatalk 3.x configuration file

hostname=redacted_afp
[Homes]
basedir regex = /home

[redacted_afp]

I'm using Transmission on EOs and I've downloaded a bunch of torrent files which ended up my Download folder in my /home. I'd like now to move the files to my external hard drive without breaking the link and contribute to further sharing upload of these files. What should I do?

Decades ago I worked in a lab equipped with Apollo/Domain workstations. One of the niceties of these machines was that their filesystems where organised and accessible as directories in what appeared to be the parent of an individual machine's root directory. You accessed that "super root" with //; your home directory would be //$HOST/$HOME. It would be really nice to have such an automatic networked filesystem at home. Is there any software that does something similar (for Linux & Mac)? EDIT: as an example of something I don't see how you'd do it with the protocols mentioned below, here's something a bit sneaky I used to do: - Set up a directory of mine in a writable portion of fast harddisk space on the fastest machine on the LAN, IIRC something like mkdir -p //fysae/tmp/.bertin/home, copy login scripts and work stuff there, and then setenv HOME "//fysae/tmp/.bertin/home" (this is also where I picked up my addition to [t]csh). All that was done with shell commands which is also where I did all my work. BTW, another nice feature made all this more transparent; it was possible to reference an env. variable in symlinks so their target depended on that variable.

I have a desktop with windows 10 on it, and I have another desktop with FreeBSD on it. No virtualization. I have shared some folders on Win desktop, which I can access on LAN with other Win10 laptops. But I am unable to access these folders from freebsd desktop, how can I do it? I went through older threads, but none of the solutions worked. All of them are outdated. The samba port of freebsd has been deleted https://www.freshports.org/net/samba

I've decided to switch to the higher version of SMB in Samba (at least 2) - mostly because of the security reasons. I've tried to add to the smb.conf in the [global] section: client min protocol = SMB2 client max protocol = SMB3 server min protocol = SMB2 or just protocol=SMB2 I have restarted samba or the whole server after each try. But logs say: [1970/01/01 01:01:12.085949, 0] smbd/negprot.c:706(reply_negprot) No protocol supported ! [1970/01/01 01:01:13.153024, 0] smbd/negprot.c:706(reply_negprot) No protocol supported !

I think I had not done this and it was working just becasue of smb.conf.
Here is my FSTAB: roc /proc proc defaults 0 0 /dev/mmcblk0p1 /boot vfat defaults 0 2 /dev/mmcblk0p2 / ext4 defaults,noatime 0 1 UUID=34150b89-5e8b-4769-8b68-f403659c58f7 /media/USBHD auto defaults,_netdev 0 2 And here is the smb.conf part defining the shared folder: [USBHD] comment=Dysk udostepniony path = /media/USBHD valid users = @users force group = users create mask = 0777 directory mask = 0777 read only = no writeable = yes browseable = yes public = yes Should I edit FSTAB? How?
When is it possible to configure version protocol like in the MAN page in the smb.conf, when it's necessary to do this in FSTAB?
**I guess that *min protocol* may not be available in the Samba version I use. But anyway, it supports SMB2 protocol, so how can I switch it on?** Samba version 3.6.6

I am on Ubuntu 20.04 and I have users who work on Jupyter notebooks in their own home directories, and then they can move the notebook onto a shared directory on the Jupyter server where everyone can read them, but not edit or delete them. Only the owner should be able to delete and edit. I tried to work with the setgid and sticky bits, and the last issue I have is that if the file has 664 permissions, I don't see a way to change it to 644 so only the owner can change it.

Given that I have the infohash of a torrent and the URL of a BitTorrent tracker (e.g. udp://tracker.example.com/announce), how do I use the command line to get all the IP addresses of peers that the tracker knows about? I am using Ubuntu 20.04.

Is it possible to use "Filesystem Passthrough" virtual hardware option inside virt-manager to share a folder on my Linux host with my Windows guest? I found some tutorials for how to do this with a Linux guest, but when I try this with my Windows guest I receive the following error message when attempting to start the VM: Error starting domain: Unable to read from monitor: Connection reset by peer Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 100, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 122, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1210, in startup self._backend.create() File "/usr/lib64/python2.7/site-packages/libvirt.py", line 698, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: Unable to read from monitor: Connection reset by peer I tried sourcing some documentation but all I could find was the official page linking to a FAQ and "some screenshots" .

I have a linux server that I manage via SFTP and SSH. Some files are generated on the server through scripts. How can I make it so that I can give users on the Internet links to specific files (so that a specific user can only access one converse file) that are on this server? What technology stack do I need to learn? I would like to automate this process so that I run the script, it generates a file for the user and I would immediately see a link that I would give to the user. Is this even possible to do? If it is important, then the server has a domain name, and also runs on CentOS 7.

In Linux, specifically RHEL/CentOS 7.9, but anything equivalent or of a later version... if I wanted to mount a folder/directory from another Linux system across a network, all I am aware of is NFS, either NFSv3 or NFSv4. Is there any other mount method, that is functionally comparable to NFS, for mounting some exported (shared) folder/directory from another Linux system on the network?
