iptable rule to match system service

in flag

I have this rule:

sudo iptables -t mangle -A OUTPUT -m owner --uid-owner myuser -j MARK --set-mark 1

But instead of matching with a user, I would like to match with a system service. Cold you help me?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
