So, this is my setup: I have computer A and a computer B, both with Ubuntu 20.01. Each computer has openssh-server working just fine. Yesterday, I used rsync to copy a large file from A to B, and it didn't seem to have any issue (it was the first time rsync was used). Today, I tried to connect via SSH from B to A and I had a "No route to host" error. Then I tried to connect via SSH from A to B and "No route to host" happened again. Then, on each computer I did a: ssh user@127.0.0.1 and none gave me any issue. Then, I did a: ssh -T git@github.com on both computers and both were successful. Then, I did an: nmap -Pn -p22 192.168.xx.yy on both computers trying to connect to the other, the results are: PORT STATE SERVICE nmap tested in A with IP of A: 22/tcp filtered ssh nmap tested in A with IP of B: 22/tcp open ssh nmap tested in B with IP of A: 22/tcp filtered ssh nmap tested in B with IP of B: 22/tcp open ssh What really bugs me out is that yesterday, before using rsync, the ssh connection was working just fine. The file was copied successfully, and both computers have been restarted since, so I don't know if there's some file that was corrupted or something like that. I'm not even sure if the rsync is what caused the issue. Just to be sure, in computer A, I did a: sudo lsof -i -P -n | grep 192.168 And the only IP address that I see is the one from A. Not sure if this might help, but I only used one rsync command, and is the one that follows: rsync -rvz -e 'ssh -p XXXX' --progress /PATH/TO/SOURCE/FILE user@192.168.xx.yy:/PATH/TO/DESTINATION/FILE EDIT: I don't think the path is the issue, since I ran rsync from a dicerctory in /home/user, but for disclosure, the actual rsnc command was: rsync -rvz -e 'ssh -p 2222' --progress ./someDB.sql user@192.168.0.70:/home/user/DBs And as for the absolute path of where I ran the command, it was: /home/user/DB/

I have estimated 44 GB of data from my web server. I want to transfer it to another server with less time. I am using Putty to transfer file. is there any way to achieve this? I don't know which commands to use but some blogs said to use rsync or scp to transfer these files. your help is greatly appreciated. I've tried scp from local to server but I what I need is from server to server.

Let us assume we have three computers (they are all running a modern linux distro) call one a jumpbox, and two others PCs: Jumpbox / \ / \ / \ PC1 PC2 **PC1 has a reverse ssh tunnel into jumpbox on port 39999** **PC2 has a reverse ssh tunnel into jumpbox on port 39998** *Jumpbox has no local disk space to spare.* **How do you setup an rsync over ssh to sync files from PC1:/myfiles to PC2:/myfiles?** Note, currently the connections all work, with shared keys: From jumpbox: ssh localhost 39999 will get a login to PC1 ssh localhost 39998 will get a login to PC2 Tried and failed to accomplish this, from PC1, PC2 or even Jumpbox. From jumbox, tried to setup rsync but unsure how to specify ports for each destination. This page offers some insights, but does not seem to work. Also, the scp suggestion at the bottom does not specify ports (which would work, note you can do remote to remote copy, but not sure how to set a -P for each host?) **Update, with temporary solution:** After reading this page , and then this page , the scp + tar solution was tested and found to work from the jumbbox. Using some of tars features, although not as nice as rsync, gets the job done. Just to note, rsync is not intended for rsync remotehost:/files remotehost2:files. I am not a windows user, but if jumpbox were windows based something like WinSCP would work, which I have seen previously. The basic solution can be found in "nortallys" answer on this stack exchange post . Basically: ssh -p 39999 localhost 'tar -cf - /path/to/files/to/copy' |ssh -p 39998 localhost 'tar -xvpf - -C /' This works for now, and switches to tar have been added to mimic rsync.

So I'm trying to transfer a bunch of files via SCP. Some of these are too large to be stored on the recipient (Android phone, 4GB file size limit). The sender is almost out of space, so I can't create intermediate files locally. I'd like to tar up the bunch and stream it through split so that I can get smaller segments that'll be accepted by the phone, i.e. local command: tar -cvf - ~/batch/ | split --bytes=1024m - batch.tar.seg But I'm not sure how I'd pipe that into scp to get it the phone. According the comment on [this post](http://gnuru.org/article/1522/copying-with-scp-stdin) , it's possible, but I first of all don't quite get what he's saying, second of all I'm not sure how to accomplish this as there'll be multiple files output from split. Any ideas?

If you read all from post [How to copy all files from a directory to a remote directory using scp?](https://unix.stackexchange.com/q/232946/100397) you will find there is no answer that actually (as in ALWAYS) works, even though a (non)answer has a big green check mark. I have the following "solution" but am asking whether someone knows a less cumbersome method. 1) Use "scp -r" to copy local_directory to remote_directory -- note that local_directory will be placed within remote_directory which is NOT desired but is easily fixed... 2) On remote machine create links within remote_directory to the files within remote_directory/local_directory -- I recommend the "find" command executing the "ln" command to accomplish this. 3) On remote machine use "rm -r remote_directory/local_directory" to remove unwanted directory.

Is there a reason to use scp instead of rsync? I can see no reason for using scp ever again, rsync does everything that scp does, with more safety (can preserve symlinks etc).

In my terminal shell, I ssh'ed into a remote server, and I cd to the directory I want. Now in this directory, there is a file called table that I want to copy to my local machine /home/me/Desktop. How can I do this? I tried scp table /home/me/Desktop but it gave an error about no such file or directory. Does anyone know how to do this?

My attempts to transfer a file to a remote Windows 7 computer have failed: - TeamViewer times-out - WinSCP times-out I am forced to re-start (vs. resuming) transferring the files. I have temporarily positioned the file on my Linux router and opened the SSH port for WinSCP. I can periodically access the remote (Windows 7) computer and WinSCP is available. It would be nice if WinSCP had rsync built-in. Is there a robust (can resume session disconnects) file transfer protocol or app that will persistently reconnect until the transfer is completed (through SSH port 22)? - Update: SFTP retrieved via ipkg to Linux router: SFTP tested and confirmed - Update: Only the SCP connection over port 22 connected.

I have in my SSH

~/.ssh/config

the following configuration:

Host *
     # note: this needs in /etc/ssh/ssh_config:  PermitLocalCommand yes
     #
     LocalCommand gpgconf --reload scdaemon

The reason for this is, the private RSA key for the SSH connection comes from an OpenPGP smartcard which is requesting a PIN to give access and the card should be resetted with the above command after providing the key. This works fine for SSH, but not for SCP. SCP launches the required SSH command with an option

"-oPermitLocalCommand=no"

which disables this feature. One can see this nicely with:

strace -f -o scp.tr scp "-oPermitLocalCommand=yes" foo www.unixarea.de:.
...
grep execv scp.tr
10205 execve("/usr/bin/scp", ["scp", "-oPermitLocalCommand=yes", "foo",
"www.unixarea.de"...], 0xffffdf2147a0 /* 32 vars */) = 0
10206 execve("/usr/bin/ssh", ["/usr/bin/ssh", "-x", "-oPermitLocalCommand=no",
"-oClearAllForwardings=yes", "-oRemoteCommand=none", "-oRequestTTY=no", "-o",
"PermitLocalCommand=yes", "-oForwardAgent=no", "-l", "XXXXXXXXXXXXXXXX", "--",
"www.unixarea.de", "scp -t ."], 0xffffe38c6780 /* 32 vars */) = 0

and so the card remains active and provides keys without PIN entry. This is on some Debian version of Linux, PureOS:

purism@pureos:~$ ssh -V
OpenSSH_8.4p1 Debian-5+deb11u3, OpenSSL 1.1.1w  11 Sep 2023

How could this be changed?

Using ssh, it is easy to print the contents of a file using ssh host 'cat file.txt' When ssh is disabled, and only SFTP is enabled, running the previous command gives the following error: > This service allows sftp connections only. To work-around this issue, I could create a temporary file using scp or sshfs (as shown below), but that looks really ugly. What is the proper way to print the contents of a remote file when SSH is disabled? mkdir tmpdir sshfs host: tmpdir cat tmpdir/file.txt fusermount -u tmpdir # This does not work! scp -v host:file.txt . shows # "Sink: This service allows sftp connections only." scp host:file.txt . cat file.txt rm file.txt

I'm trying to use the SCP command to copy a file from Linux to Windows, the error I'm getting is practically identical to this question; https://stackoverflow.com/questions/61721025/pam-unix-sshd-authentication-failure-even-though-the-login-works . And this is the SCP command I'm using in Linux; scp /volume1/homes/%userName%/imageConvert/x.png %username%@Ipv4Address:/C:/8/ to copy the x.png image to the folder C:\8 on Windows. I've searched on identical issues that it can be a firewall blocking SSH/SCP I've checked Windows Defender Advanced Security if the remote host is being block and I see nothing showing a block ?

I know that is a popular subject but I can not find the right solution for my problem. On my pc I use scp and ssh with OpenWrt firmware, usually I use Debian or linux mint without any problem, but I did a fresh install and I got problem now with my firmware config back up. Here what I use since 2 years without any problem.

#  openwrt_backup
# Create tar_main
ssh root@192.168.1.1 sysupgrade -b /tmp/backup-main-$(date +%F).tar.gz

# Copy to local dir
scp -O root@192.168.1.1:/tmp/backup-*.tar.gz james@ninja:/run/media/james/E/openWrt_backup/

The problem is right now that after the second command, transfert the backup to my local pc, nothing happens:

james@ninja:~> scp -O root@192.168.1.1:/tmp/backup-*.tar.gz james@ninja:/run/media/james/E/openWrt_backup/
james@ninja:~>      # empty answer??

Idea? thanks

I am trying to achieve to perform scp via specific NIC. I read [scp man page](https://man.openbsd.org/scp) but couldn't find required flags.

In my Linux terminal, I am using this command sshpass -p "pass" scp -r me8@host.ca:/cmshome/me/file /home/me/Desktop to download a file with a password in it. Without the sshpass, I can see the download progress, but with it, it is just blank until it finishes and I can't see it. Is there a way I can see it with sshpass?

I've been experiencing very strange behavior of SCP for some time: whenever I try to copy a file, the output of SCP contains a bunch of underscores and the file is not copied. $ scp test.txt 192.168.0.2:~ job@192.168.0.2's password: ________________________________________ When I create an SSH connection using Midnight Commander and copy files it does work.

I'm trying to backup my project, databases & nginx environnement. For that, I'm doing backup from my main server and place it in /home/backup/. Everything work on the main server. Then, from my second server, I'm creating a cron to get that files through SCP. Here is my command : 0 13 * * * sudo sshpass -p MyPassword sudo scp -P 40511 -r user@mydomain.com:/home/backup /home I'm using port 40511 as SSH. The command works if launched manually, but doesn't work with cron. MyPassword contain an "!". I tried with and without double-quote. What am I doing wrong ?

I want to make my openwrt backup with command from my local terminal, pretty easy, but my problem is after that, it is when I try to bring back the backup to my local pc. Here what I have for now, first part is ok:

#!/bin/bash

ssh root@192.168.1.1 sysupgrade --create-backup /tmp/main_backup.tar.gz

with that command I create my router's backup and I want to scp that backup to my local pc.

Here's what I'm trying to do (in a script):

#!/usr/bin/env bash

if [[ ! $("/usr/bin/scp seamus@fumier.local:/Users/seamus/Downloads/imgutils/image-utils* /home/pi/testscp") ]]; then
    printf "\nERROR & EXIT: 'scp' failed \n"
    exit 1
fi
printf "success!\n"

I've tried doing this in a few ways, but nothing seems to work. Here's what I get from the above:

./testscp.sh: line 3: /usr/bin/scp seamus@fumier.local:/Users/seamus/Downloads/imgutils/image-utils* /home/pi/testscp: No such file or directory

ERROR & EXIT: 'scp' failed

The scp command runs OK when it's on a line by itself. If I do that, I can test for $0 - which works OK... but I'd prefer to do it all in a single line. What am I missing?

I'm trying to copy a batch of files with scp but it is very slow.

Any idea where this overhead comes from, and is there any way to make it faster?
