A flap on the interface that appears to have come from the attached cable modem dropping the link to the unit momentarily resulted in a rebind BUT the address never got re-assigned to the igb0 interface. A manual ifconfig down/up fixed it, but this was a quite-severe incident because it left the external connection completely invisible -- if there had been nobody available on the "inside" to do that manually..... I'm on 12-STABLE r343809 on the specific box in question. -- Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/ [-- Attachment #2 --] 0 *H 010 `He 0 *H 00 H^Ōc!5 H0 *H 01 0 UUS10U Florida10U Niceville10U Cuda Systems LLC10U Cuda Systems CA1!0 U Cuda Systems LLC 2017 CA0 170817164217Z 270815164217Z0{1 0 UUS10U Florida10U Cuda Systems LLC10U Cuda Systems CA1%0#U Cuda Systems LLC 2017 Int CA0"0 *H 0 h-5B>[;olӴ0~͎O9}9Ye*$ g !ukvʶLzN`jL>MD'7U 45CB+kY`bd~b*c3Ny-78ju]9H euέsӬDؽmgwER?&UURj'}9nWD i`XcbGz \gG=u%\Oi13ߝ4 K44pYQr]Ie/r0+eEޝݖ0C15Mݚ@JSZ(zȏ NTa(25DD5.l<g[[Z arQQ%Buȴ~~`IohRbʳڟu2MS8EdFUClCMaѳ !}ș+2k/bųE,n当ꖛ\(8 WV8 d]b yXw ܊:I39 00 U ]^§Q\ӎ0U #0T039N0b01 0 UUS10U Florida10U Niceville10U Cuda Systems LLC10U Cuda Systems CA1!0 U Cuda Systems LLC 2017 CA @Ui0U 0 0U 0 *H :P U!>vJ n io -#ן]Wyu jǑR̀Q nƇ!G ѦF g\ yLx gw=OPycehf[ }ܷ['4ڝ\[p 6\o.B&JF" ZC{;*o*mcCcLY߾` t*S!(` ]DHP5A~/NPp6=mhk밣'doA$86hm5ӚS@ j ެEgl )0JG`%k35PaC?σ ׳HEt}!P㏏%*BxbQwaKG$6 h¦Mve; [o-Iی& I,Tc ߎ#t wPA@l0P+KXBպT zGv;NcI3&J ĬUPNa?/%W6G۟N000 k#Xd\ =0 *H 0{1 0 UUS10U Florida10U Cuda Systems LLC10U Cuda Systems CA1%0#U Cuda Systems LLC 2017 Int CA0 170817212120Z 220816212120Z0W1 0 UUS10U Florida10U Cuda Systems LLC10U karl@denninger.net0"0 *H 0 T[I-ΆϏ dn;Å@שy.us~_ZG%<MYd\gvfnsa1'6Egyjs"C [{~ _K Pn+<*pv#Q+H/7[-vqDV^U>f%GX)H.|l`M(Cr >е͇6#odc"YljҦln8@5SA0&ۖ"OGj?UDWZ5 dDB 7k-)9Izs-JAv J 6L$Ն1SmY.Lqw*SH;EF'DĦH]MOgQQ|Mٙג2Z9y@ y]}6ٽeY9Y2xˆ$T=e CǺǵbn֛{j |@LLt1[Dk5:$= ` M 00<+00.0,+0 http://ocsp.cudasystems.net:88880 U 0 0 `HB0U 0 U %0++03 `HB &$OpenSSL Generated Client Certificate0 U %՞V =;bzQ0U #0]^§Q\ӎϡ01 0 UUS10U Florida10U Niceville10U Cuda Systems LLC10U Cuda Systems CA1!0 U Cuda Systems LLC 2017 CA H^Ōc!5 H0 U 0karl@denninger.net0 *H ۠A0-j%--$% g2#ޡ1^>{K+uGE v1ş7Af&b&O; .;A5* U)ND2bF|\= ]<sˋL!wrw٧> YMÄ3\mWR hSv!_zvl? 3_ xU%\^#O*Gk̍YI_&Fꊛ@&1n } ͬ:{hTP3B.;bU8:Z=^Gw8 !k-@xE@i,+'Iᐚ:f hztX7/(hY` O.1}a`%RW^akǂpCAufgDix UTЩ/7}%=jnVZvcF<M= 2^GKH5魉 _O4ެByʈySkw=5@h.0z> W1000{1 0 UUS10U Florida10U Cuda Systems LLC10U Cuda Systems CA1%0#U Cuda Systems LLC 2017 Int CA k#Xd\ =0 `He E0 *H 1 *H 0 *H 1 190418144339Z0O *H 1B@ "^ɕ=L! t# ^:[ѕ˱f܍06lKP;SDr0l *H 1_0]0 `He*0 `He0 *H 0*H 0 *H @0+0 *H (0 +7100{1 0 UUS10U Florida10U Cuda Systems LLC10U Cuda Systems CA1%0#U Cuda Systems LLC 2017 Int CA k#Xd\ =0 *H 10{1 0 UUS10U Florida10U Cuda Systems LLC10U Cuda Systems CA1%0#U Cuda Systems LLC 2017 Int CA k#Xd\ =0 *H W(gGLl{_~3~ k"[ N0 uziw>Vl'"ylO }6e~!`~1ag~Yh$:NKҧ. 717[=p^n^{ꓻI~Tʆ# hz K,)t0y uHܥ{<G:qWOh _ײ S `|ή:.Гc3WIn: ʄQSL'Q/<HFtaa8mfUe6FafфEփE ̟WwBlj% 'a#F6 ?%WƏ4 AvKmfIeyWKD/D2K?`rvia?w1nPǞAvHȚ4Pnî -5VS<)ζ!9ؘgKO^4Q ByZi(i2|sc NQӖc
