We have FW 07.04.2 installed on several RUT955 modems.
I used SCP client to browse to /etc/crontabs/ and opened the root file.
I deleted the contents of this file, and put in a 5-minute executing script, which works great:
*/5 * * * * /root/myscript.sh
However, about a week later, the script stopped executing, and I noticed the following text was appended to the file:
33 12 * * 4 /sbin/rut_fota --fw_info >/dev/null 2>&1 #746c74
It was not put on a new line in the file, thus voiding the previous statement I wrote. It was appended to the end with no spaces.
What does this text do, and why was it forcibly put back in the root file? Should I not have cleared the root file’s initial contents, or did I do something wrong? Thanks.
