Scans from Russia

["Infrastructure Dept." <infrastructure () narellan net>]

I check my logs more than daily so I usually catch stuff soon after the
occurrence. Here's something I saw this morning. Can someone tell me what
the flags mean or where I can find a list of 'flags'

Sep 20 00:27:21 ns1 scanlogd: From 213.156.132.118 to x.x.x.x ports 1999,
745, 602, 6003, 144, 3333, 32771, 53, 2049, ..., flags fSrpau, TOS 00, TTL
42, started at 00:27:19
