[SOLVED] TFTP in Debian 8.0

[tigger]

Hello,

I'm a beginner to Debian Linux and I have a question regarding TFTP.
I'm trying to run it in script.
#!/bin/bash
FILE="/home/eclipse/test.txt"
tftp 192.168.0.50 << '!'
put ${FILE} /remote/directory
quit
!
exit 0

When I run it:
tftp: ${FILE}: No such file or directory

I've done many researches, but couldn't solve it.
Please help!

When I run it:
tftp: ${FILE}: No such file or directory

Looks like the path to the file is not correct, where is the file?
${FILE} = what exact path?

Hello TonyT,

It's located in /home/eclipse/
It works when I manually typed in.
tftp 192.168.0.50 << '!'
put /home/eclipse/test.txt /home/eclipse/test.txt /remote/directory/
quit
!

Terminal respond:
Sent 5627 bytes in 0.0 seconds
Sent 5627 bytes in 0.0 seconds

Disclaimer: I'm horrible at bash scripting... That said, I think it should look like this....

Code: Select all

#!/bin/bash
export FILE=/home/eclipse/test.txt
tftp 192.168.0.50 << '!'
put $FILE /remote/directory
quit
!
exit 0

Hello Bryanmc,

I've done that but same result...
tftp: $FILE: No such file or directory

I've tried others:
With the quote -> export FILE="/home/eclipse/test.txt" or, FILE="/home/eclipse/test.txt"
Without the quote -> export FILE=/home/eclipse/test.txt or, FILE=/home/eclipse/test.txt
With braces {}, parentheses (), quotation "" around FILE
However, no uses..

Is "/remote/directory" world writable?

Hello Bryanmc,

I've done that but same result...
tftp: $FILE: No such file or directory

But did you export the variable for FILE?

export FILE=/home/eclipse/test.txt

[tigger]

Is "/remote/directory" world writable?

Yes, it's writable.

But did you export the variable for FILE?

export FILE=/home/eclipse/test.txt

Yes, I've done that.

Try this -

Code: Select all

#!/bin/bash
FILE = "/home/eclipse/test.txt"
tftp 192.168.0.50 -c put ${FILE} /remote/directory
exit 0

Part of the problem you appear to have is that some versions of FTP (and TFTP) don't invoke a shell so you can't pass shell variables to them.

Good luck -

wizard10000, thanks for your advice.
I'm currently using tftp-hpa 5.2, with remap, with tcpwrappers.

I got following respond now:
usage: tftp host-name [port]
tftp>

I had to enter "quit" to exit from there.

Check the man page for your tftp client and see if it supports the -c switch. It's possible you're not able to pass shell variables to your tftp client - if that's the case you may not be able to get there from here

edit: I just installed Debian's tftp client and read its man page - it doesn't support -c as a command line argument. Since a tftp session isn't a shell you can't pass shell environment variables to it; you have to assign them client-side and Debian's tftp client doesn't support that.

Wish I had better news -

Okay, thanks for letting me know..

Don't use '!' as delimiter.
Instead, do like:

Code: Select all

tftp 192.168.0.50 <<EOF
put ${FILE} /remote/directory
quit
EOF
