All functions which are executed in kernel context must be fast and could freeze your system if they take too long. You passed an option that you would like to have the output of the set in a sorted manner - but the kernel module responsible for this did not know that option an simply ignored it.

As such, ipset is just a wrapper to call the actual code, which resides inside the kernel - Including the code to list the contents of a set. Some background information on ipset: This is a command line tool to manipulate datasets which resize within the kernel memory. How can I fix this so that the output is organized? k 1,1n -k 2,2n -k 3,3n -k 4,4n -k 5,5n -k 6,6n -k 7,7n -k 8,8n -k 9,9n | while read line doĮcho 'add blacklist $line' > /tmp/ipset.txtīut the output remains the same, no-sort, when I run ipset -L, so the -sorted (-s) option is not working in restore I have this bash script of ipset v7.15 (run in ubuntu 22.04), courtesy of Martin (that I have made some modifications for this question): ipset create -! blacklist hash:net family inet hashsize 1024Ĭat list.txt | sort -t.
