What does this SCP error mean and how can I make SCP work?

laredotornado · 02-24-2018, 02:57 PM

I'm using CentOS 7. I'm trying to scp some files up to my VPS (using A2Hosting). Although I can SSH just fine, I'm getting this error using SCP that I don't understand

Code:

localhost:tmp davea$ scp -P 7822 ~/Documents/workspace/mydir console-afOMU5@my_ip_address:/tmp
console-afOMU5@my_ip_address's password:
Entering CT
Unable to get term attr: Invalid argument

What does this mean but more importantly what do I need to do to transfer the files?

Have you tried SFTP? SCP is a bit of a kludge, while SFTP is a standard. I believe that there i a way to run CP in FTP protocol format, but I would rather just do SFTP in the first place.

are you sure the username is console-afOMU5?

you can also try to prepend 'TERM=dumb'.

Hi, Yes, I can SSH in using the same port and credentials. I suspect this is because this usernam/epassword is issued through A2Hosting's serial console, which seems to be some kind of temporary session. Not sure why that would prevent SCP but allow SSH, but oh well.

I think it's your use of the tilde in the command.

Just sayin'.

If the KORN or BASH shell is being used, that tilde should be expanded and the full resulting path provided as the parameter.
Just sayin'

The point, though, is somewhat valid since we do not KNOW what shell the OP is using.

i vaguely remember that scp has problems with expanding commandline arguments. not sure how it does it (circumvent the shell? seems impossible), but so i heard.
maybe "~" is not the same as "$HOME"?

interestingly, when i type

Code:

scp ~/<Tab><Tab>

it immediately expands to

Code:

scp /home/ondoho

when i do the same for cp:

Code:

cp ~/<Tab><Tab>

the "~" remains unchanged.

just sayin.
