[CentOS] POOR: results using 'dig +short porttest.dns-oarc.net TXT'
What are the likely cockpit errors involved when getting POOR results when running this test on an updated CentOS 5.2? Kind regards/ldv [root at shell ~]# dig +short porttest.dns-oarc.net TXT z.y.x.w.v.u.t.s.r.q.p.o.n.m.l.k.j.i.h.g.f.e.d.c.b.a.pt.dns-oarc.net. "a.b.c.d is POOR: 26 queries in 1.3 seconds from 1 ports with std dev 0.00"
