SCP command not found

[c9dy]

Have a slight issue in that I cant scp from a centos6 server to a cent os 7 server (and vice versa)

Get the error on either server

Code: Select all

-bash: scp -p6336: command not found

Command im using is

Code: Select all

scp -p6336 myfile.text root@newserersvip:/directoryonnewserver/

port 6336 is ssh this has been changed and works fine

running CFS firewall and posts open and its whitelisted

openssh clients installed on both servers

I can ssh to either server in terminal......

Tried quite a few things and at a loss so any help appreciated

Though not an answer, please note that with scp (as opposed to ssh) it should be -P, not -p for port number, e.g., scp -P 7777 file1 server2:


Also, doing (on CentOS-8)

Code: Select all

dnf provides scp 

shows that it requires ssh-clients, though I suspect that's a default package with install.

Sorry the -p was a -P typo here

[TrevorH]

-bash: scp -p6336: command not found

I'm going to go with: that's not a space between scp and -p so it's treating the whole thing as one string and searching for a command called "scp -p6336".

How about using rsync?

Code: Select all

# rsync -av -e "ssh -p 6336" myfile.text root@newserersvip:/directoryonnewserver/

Or preferably with connection alias:

Code: Select all

# cat ~/.ssh/config
Host newsrv
  User root
  HostName newserersvip
  Port 6336
#
# rsync -av myfile.text newsrv:/directoryonnewserver/

Bash doesn't say what it says unless it thinks the whole thing is one word:

Code: Select all

[trevor@centos8 mate]$ scp -p6336
usage: scp [-346BCpqrTv] [-c cipher] [-F ssh_config] [-i identity_file]
            [-J destination] [-l limit] [-o ssh_option] [-P port]
            [-S program] source ... target
[trevor@centos8 mate]$ scp\ -p6336
-bash: scp -p6336: command not found
[trevor@centos8 mate]$

ssh-clients, though I suspect that's a default package with install.

On both CentOS 7 and 8:
* ssh-client is a mandatory package for group Core
* group Core is mandatory group for every Environment Group

It is thus quite a feat to not have scp installed.

[c9dy]

rsynch doesn't work either

ssh clients is installed

On my other servers this works just fine between A & B and B & A (A & B are CentOS 6.x)

Code: Select all

root@server [~]# scp -P6336  php7.zip root@IPADDRESS:/home/
root@77.245.68.3's password: 
stdin: is not a tty
php7.zip                                                                                               100%  142KB 142.3KB/s   00:00    
root@server [~]# 

The new CentOS7 (say Server C) server just won't have it to or from A or B but ssh is fine

Whatever it is that you're running, when bash says "scp -p6336" is not found, it means it's trying to run that as one command. It either means that's not a space or you're somehow managing to invoke "scp -p6336" instead of "scp" "-p6336". If it couldn't find scp it would say "-bash: scp: command not found"
