Tftp Connection refused only at T41xxx.rom


(Z R) #1

Hi All,
I get always from tftp this message: “tftpd: read(ack): Connection refused” only at T41xxxxxx.rom and at other xxx.rom files.
Privileges:
-rwxrwxrwx 1 asterisk asterisk 7282896 Nov 9 2017 T41xxxxxx.rom

P.s.: T41xxxxxx.rom is replaced only in this email. It has a valid version name on server.

Do you have any idea why?

Thanks
RZ

I believe the file size is too large for tftp. Try provisioning with http.

The file size limit for TFTP should be 32M (16 bit block numbers on 512 byte blocks).

The following look like they might have some pertinent information.

The most common reason for this is because the host you are trying to TFTP from is not in the local network.

Yealink phone can download all files except .rom files. So the TFTP transfer runs only for all .cfg and .xml files.

Use http instead of tftp for provisioning and the Yealink phone will download the .rom firmware file as well.

Hi,

Thanks.

I’m just configuring the httpd.conf.

Thanks!:slight_smile:
I found the port in /etc/httpd/conf.d/schmoozecom.conf.
I set it in y000000000036.cfg

It’s already working well.
