<pre>I tried to pipe several commands to ipset but if one of them have a syntax
error then the following command will get the typename of the before.
What I did:
create ipset:
# ./ipset create test hash:net
# ./ipset create test_iface hash:net,iface
pipe commands:
Only the second command has a wrong syntax but the third command return an
error too.
# echo -e "add test 1.1.1.1\nadd test_iface 2.2.2.2\nadd test 3.3.3.3\n" |
./ipset -
ipset v6.32: Syntax error: Second element is missing from 2.2.2.2.
ipset v6.32: Syntax error: Second element is missing from 3.3.3.3.
# ./ipset list

Printing "setname" and "typename" in types.c:adt_type_get() shows that in the
third command "test" has the typename "hash:net,iface" instead of "hash:net".
# echo -e "add test 1.1.1.1\nadd test_iface 2.2.2.2\nadd test 3.3.3.3\n" |
./ipset -
ipset> setname: {test}
typename: {hash:net}
ipset> setname: {test_iface}
typename: {hash:net,iface}
ipset v6.32: Syntax error: Second element is missing from 2.2.2.2.
ipset> setname: {test}
typename: {hash:net,iface}
ipset v6.32: Syntax error: Second element is missing from 3.3.3.3.
# ./ipset -v
ipset v6.32, protocol version: 6</pre>
