I'm backing ip my server via rsync over ssh but /var/log/lastlog file is 1.2G (it takes only 24K on the hdd). On a local machine cp can copy it for no time (a few ms) but rsync requires reading the whole file which takes hours. I also tried to mount server's /var/log with sshfs to my local pc but my local pc detects the file as 1.2T (so sshfs doesn't appear to detect sparse files). Is there some program that detects sparse files over ssh and can copy them the same way cp (without reading the empty blocks from the file) does? EDIT: rsync's -S/--sparse option still wants to read the whole source file (with all the empty bytes) which takes hours for 1.2T file. After rsync reads the whole file it creates small destination file (proper sparse file) but the problem is that it reads the source file with all the empty bytes (without skipping them). cp copies the file in a few ms while rsync takes hours. You can try it (on Linux) by creating 20G sparse file with truncate -s 20G sparse_file1 and copy it with rsync -S sparse_file1 sparse_file2 (takes long time) and then try to copy it with cp sparse_file1 sparse_file3 (takes a few ms).

SSHFS changes modification date (not access date) of server files on download(!). Is there an option/setting to prevent that? The problems this causes include: - after the next download, you can't sort the files by date anymore. - when we backup to the server, every file will be transferred on every occasion (bc their dates are always different) - in the use-case of sharing updated files on the server: everything will be downloaded every occasion even if no-one uploaded anything UPDATE: After changing operating systems and taking 2 weeks to restore modification dates from backups (making sure that actually-modified files don't get their date restored...), there are two machines remaining with which we can reproduce the behavior: Server: Linux Mint 21.2, sshfs 3.7.1, fuse 3.10.5, fuse ki 7.31 fusermount3 3.10.5 Client: GhostBSD 14.2 (a modified FreeBSD 14.2-RELEASE-p1), sshfs 3.7.3, fuse 3.17.1, fuse ki 7.40, mount-fusefs 0.3.9-pre1 - Download Command: cp -pr mnt/content/ local/content/ - mount command: sshfs a@192.168.1.4:/home/a/server-dir mnt/ ----

I have to HDD drives on two different servers that I need to sync regularly. Until now, I've been using rsync over sshfs, first from one to the other, then from the other to the first, but this method is proving unsatisfactory. When a file is removed from drive A, it is not copied to drive B, but then copied from drive B to drive A. So I can never remove anything unless I do it from both drives. The same goes for renaming - renaming a directory on one drive soon results in two directories with different names but the same contents. Ideally I need something that keeps track of changes on one drive and then duplicates these changes on the other. Any suggestions?

I mount four servers (3 via cifs, 1 via sshfs) using autofs. auto.master /- /etc/auto.all --timeout=60 --ghost auto.all /mnt \ /server1 -fstype=cifs,rw,credentials=/etc/.smbcredentials.txt,uid=1000,file_mode=0775,dir_mode=0775,users ://server1/ \ /server2/ -fstype=cifs,rw,credentials=/etc/.smbcredentials.txt,uid=1000,file_mode=0775,dir_mode=0775,users ://server2/ \ /server3 -fstype=cifs,rw,credentials=/etc/.smbcredentials.txt,uid=1000,file_mode=0775,dir_mode=0775,users ://server3/ \ /server4 -fstype=fuse,rw,allow_other,uid=1000,users,reconnect,cache=yes,kernel_cache,compression=no,large_read,Ciphers=arcfour :sshfs\#user@server\:/home ``` Everything is fine when I make a clean boot. I connect to my network (using a VPN) and autofs mounts everything. # Problem When there is a network disconnect, e.g. when I hibernate my laptop or connect to a different network, autofs causes my explorer (dolphin) to freeze because it tries to load the remote share infinitely. It becomes unresponsive and does not even react to SIGTERM commands. Sometimes I am lucky and calling sudo service autofs stop and sudo automount helps to resolve the issue. However, often it still stays freezed. Sometimes even, my whole dock freezes due to this making all applications unselectable. Then I have to make a full reboot.. I've searched for weeks now for solution how to deal with autofs in such situations. Before using autofs, I had everything mounted via /etc/fstab but that also required a manual remount after every network interruption. I thought autofs would help me here but it causes me even more trouble. # Questions 1. Is there any point I overlooked that could solve the freezing problem? 2. Is there a completely different approach that may be better suited for my situation than autofs? PS: I'm on Kubuntu 16.04

I want to mount a remote directory and I want to automate this. So I write below script which not working properly. #!/usr/bin/expect -f spawn sshfs vedams@192.168.5.109:/home/user /mnt/remote expect "assword:" send "myPassword\r" When I run the above script and if check ls /mnt/remote, it is giving below error: ls: cannot access /mnt/remote: Transport endpoint is not connected I used sshpass but not working: sshpass -p myPassword sshfs user@192.168.5.109:/home/user /mnt/remote Shell blocked and getting the same error. Note: If I run sshpass -p vedams123 sshfs vedams@192.168.5.109:/home/user /mnt/remote, working withour any problem.

I need to mount a share using sshfs. When I mount it using sshfs directly, i.e. # sshfs martin@192.168.1.10:/home/data/ -o allow_other /mnt/data/ or # sshfs martin@192.168.1.10:/home/data/ -o allow_other,default_permissions /mnt/data/ the share is mounted, but only in "read-only" mode. However when I add following line into /etc/fstab, and do mount /mnt/data, then the share is mounted read-write. # martin@192.168.1.10:/home/data/ /mnt/data fuse.sshfs noauto,_netdev,allow_other,default_permissions 0 0 Both commands are issued unde root. Why does sshfs from the command line mount the filesystem read-only? How can I mount it read-write using the sshfs command?

I need help for a bash script that counts files and folders in a specified directory on a Linux system (Debian), but I want to exclude a specified folder. I have a main directory named workdir with different script files and folders. Inside workdir, I have a directory named mysshfs. I use fuse/sshfs to mount an external folder in the mysshfs folder. Now I will run some commands to get information about the **file/directory** count and **file/directory** size, but I want to exclude the directory mysshfs. My bash commands that work: 1. Get the full size of workdir | **no fuse/sshfs in use** $ du -hs workdir 2. Get the full size of workdir, excluding mysshfs | **fuse/sshfs in use** $ du -hs --exclude=mysshf workdir 3. Count files in workdir | **no fuse/sshfs in use** $ find workdir -type f | wc -l 4. Count folders in workdir | **no fuse/sshfs in use** $ find workdir -type d | wc -l 5. Count files in workdir, excluding mysshfs | **no fuse/sshfs in use** $ find workdir -type f -not -path "*mysshfs*" | wc -l 6. Count folders in workdir, excluding mysshfs | **no fuse/sshfs in use** $ find workdir -type d -not -path "*mysshfs*" | wc -l When I use commands **5 & 6** and the remote directory is mounted under the mysshfs directory, the commands hang. The commands eventually works and show the correct output, but it looks like the commands are still looking inside the excluded directory even though they shouldn't be, so it takes a long time to display the result. Where is my error or did I forget something in my commands 5 & 6? Or can I use other commands for my results? I need to count files and directories using 2 separate commands and exclude a specified folder that is mounted over fuse/sshfs to get a fast result.

I try to sshfs mount a remote dir, but the mounted files are not writable. I have run out of ideas or ways to debug this. Is there anything I should check on the remote server? I am on an Xubuntu 14.04. I mount remote dir of a 14.04 Ubuntu. local $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.3 LTS Release: 14.04 Codename: trusty I changed the /etc/fuse.conf local $ sudo cat /etc/fuse.conf # /etc/fuse.conf - Configuration file for Filesystem in Userspace (FUSE) # Set the maximum number of FUSE mounts allowed to non-root users. # The default is 1000. #mount_max = 1000 # Allow non-root users to specify the allow_other or allow_root mount options. user_allow_other And my user is in the fuse group local $ sudo grep fuse /etc/group fuse:x:105:MY_LOACL_USERNAME And I mount the remote dir with (tried with/without combinations of sudo, default_permissions, allow_other): local $sudo sshfs -o allow_other,default_permissions -o IdentityFile=/path/to/ssh_key REMOTE_USERNAME@REMOTE_HOST:/remote/dir/path/ /mnt/LOCAL_DIR_NAME/ The REMOTE_USERNAME has write permissions to the dir/files (on the remote server).

I'm trying to access a **Docker** Unix socket on a remote server from within a **Podman** container (offen/docker-volume-backup). I've (root-)mounted the entire root filesystem of the remote server using sshfs and can access it as root. However, I can't connect to the Unix socket. (All servers are on AlmaLinux with SELinux, and Podman is used with sudo.) I've tried the following settings in my Podman container:

volumes:
  - /mnt/fuse_to_somewhere/var/run/docker.sock:/var/run/docker.sock:ro,z
security_opt:
  - label=disable
privileged: 
  - true

But I still get this error:

Commands: error querying for containers: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Questions: 1. What steps are needed to connect to the Docker Unix socket from a Podman container? 2. Are there specific permissions required for accessing the Docker socket over sshfs?

After reinstalling the server I can not mount it: sshfs root@example.com:/var /remote_mount fuse: bad mount point `/remote_mount': Transport endpoint is not connected When I SSH, I get an error: # ssh root@example.com The authenticity of host 'example.com (xxx.xxx.xxx.xxx)' can't be established. ECDSA key fingerprint is 57:b6:bd:76:17:80:73:85:4a:14:8a:6f:dc:fa:fe:7c. Are you sure you want to continue connecting (yes/no)?

I’m a new PhD student and I’m dealing with a serious issue. I tried to map a directory from Server A (/home/lab/Desktop) to Server B (/home/usr/labDesktop) because Server B has better computing power. While working, all the data in the directory on Server A disappeared. Here’s a part of the sequence of commands I ran, which might have caused the problem: $ sudo sshfs lab@ipaddress:/home/lab/Desktop /home/usr/labDesktop [sudo] password for usr: The authenticity of host 'ipaddress (ipaddress)' can't be established. XXX key fingerprint is XXX. This key is not known by any other names Are you sure you want to continue connecting (yes/no/[fingerprint])? yes lab@ipaddress's password: $ ls labDesktop  examples.desktop $ cd labDesktop -sh: 44: cd: can't cd to labDesktop $ ls labDesktop  examples.desktop $ sudo sshfs lab@ipaddress:/home/lab/Desktop /home/usr/labDesktop lab@ipaddress's password: read: Interrupted system call $ fusermount -u /home/usr/labDesktop fusermount: entry for /home/usr/labDesktop not found in /etc/mtab $ ls labDesktop  examples.desktop $ cd labDesktop -sh: 49: cd: can't cd to labDesktop $ rm -r labDesktop rm: cannot remove 'labDesktop': Permission denied $ sudo rm -r labDesktop                           rm: cannot remove 'labDesktop': Device or resource busy $ mount | grep /home/usr/labDesktop lab@ipaddress:/home/lab/Desktop on /home/usr/labDesktop type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=0,group_id=0) $ fusermount -u /home/usr/labDesktop fusermount: entry for /home/usr/labDesktop not found in /etc/mtab $ fusermount -uz /home/usr/labDesktop fusermount: entry for /home/usr/labDesktop not found in /etc/mtab $ sudo umount /home/usr/labDesktop $ mount | grep /home/usr/labDesktop $ rm -r /home/usr/labDesktop $ ls examples.desktop As you can see, "sudo rm -r" threw an error message, "rm: cannot remove". So I don't believe this actually deleted the data. Moreover, I tried to unmount using "fusermount -u" before running "sudo rm -r". If "fusermount -u" failed with an error message, shouldn’t "sudo rm -r" have also failed with an error message? 1. Could this sequence of commands have caused the files on Server A to be deleted? Or is it likely something else caused the data loss? 2. How to recover them?

I'm trying to use sshfs to open a remote directory in the Spotify snap application on Linux Mint. sshfs -o allow_other user@example.com:/remote/dir /local/dir I've mounted my directory using the "allow_other" fuse option, and the directory opens without having to use sudo in terminal and file explorer. However, when I try adding it as a directory in Spotify for local files, the file explorer gives me this message: Any advice on fixing this? I've tried modifying the permissions of the folder and "default_permissions" option, no luck yet.

I can't figure how to enable more verbose logging to a systemd .mount file, but here we go my file is mnt-kreijstal.mount and has:

**Edit**: I manage to solve my problem by logging in as root and sshing into my server the problem was that my root didn't trust that server yet. Question about enabling more verbose errors remains.

I mounted sftp dir via sshfs like: cat | sshfs -o password_stdin,allow_other,default_permissions,uid=0,gid=0 $USER@$HOSTNAME: $MOUNT_DIR -oauto_cache,reconnect And the problem is that I can't delete files on $MOUNT_DIR, despite they have full permission and root as owner, e.g.: -rwxrwxrwx 1 root root 10505331 Aug 22 14:50 some_file.zip Wondering if it's at all not available when mounting sftp or it's related with the flags used on sshfs.

I would like to mount a file system on a remote machine automatically at each Linux startup. However I always need to use password authentication because I cannot use ssh-copy-id. How do I make this to be automatic without manual interaction?

I have a mounted sshfs drive at /mnt/backup_datascrape with permission rwxrwxr-x. I am trying to copy a directory foo with permission rwxrwxr-x to that mount using rsync while preserving the permissions. But when I do this, the permission for the copied directory on the sshfs mount is rwx------. If I change the permission for directory foo to rwxrwxr--, rsync correctly preserves the permissions. So in this situation it appears rsync removes all non user permissions if there is a global execute permission set. Does anyone know why this is? This is the command I use to rsync. rsync -avhz --delete --exclude 'env' /home/datascrape/foo /mnt/backup_datascrape/

It is simple enough to connect sftp server with lftp command without any key or password : lftp 192.168.31.130:3721 lftp 192.168.31.130:~> ls drwxr-xr-x 1 nobody nobody 3488 Dec 22 20:17 Android drwxr-xr-x 1 nobody nobody 3488 Jul 29 00:43 MIUI Now I want to mount the sftp server with sshfs: sudo sshfs 192.168.31.130:3721 /tmp/localdir read: Connection reset by peer sudo sshfs 192.168.31.130:3721 /tmp/localdir -o allow_other read: Connection reset by peer How can I mount sftp server with sshfs ? More info on 192.168.31.130:3721.

I've got a question that I've not been able to find an answer for. I have two computers, both of which run Ubuntu Linux 12.04. I have set up my first computer ("home") to be able to SSH into my second computer ("remote") using public/private RSA key authentication. This is not the first SSH connection that have set up using key authentication on my home computer, so my home computer has several id_rsa private keyfiles (each of which is for a different computer to SSH into). Thus, I am able to successfully SSH only when I specify a keyfile (in ssh, the -i option), using ssh username@ipaddress -i path/to/keyfile/id_rsa.2. That works great. However, I would also like to use sshfs, which mounts the remote filesystem. While ssh seems to play nice with multiple keys, I can't find a way to get sshfs to use the correct private key ("id_rsa.2"). Is there a way to get sshfs to do this?

I have several directories mounted through *sshfs*. I sometimes get disconnects from the server (not configurable by me). I usually mount the directories like this sshfs user@server.example.com:/home/user /mnt/example When a server disconnects, the sshfs subsystem doesn't *umount / free* the directory but instead locks it inaccessible. The mount is still visible when typing mount. When I type ls /mnt/example the process gets locked (also Ctrl+c doesn't help). I therefore do sudo umount -l /mnt/example # find pid of corresponding process: ps aux | grep example.com kill -9 Is there a better way to deal with this? Obviously *sshfs* should do the *umount* and clean up... Ideally it would reconnect automatically.

I have this line in my fstab: sshfs#ecarroll@o99:/opt/dealermade/ftp/inc /opt/dealermade/ftp/inc fuse defaults,idmap=user,users 0 0 For whatever reason it didn't work -- that's fine. How do I make it not stop the boot sequence. It prompted me to to hit S to skip or M to manually repair. If it isn't the boot volume, I just want my volumes to fail mounting with nothing more than an entry in logs.
