[16:55] so an interesting observation: i'm getting kernel panics attempting to install 18.04.1 on an HP Z400 workstation o.O [16:56] can't even boot the installer [18:21] teward: first up: run a memory check http://memtest.org/ [18:37] is memtest86+ upstream dead or dormant? [19:56] dormant, I think. They still answer questions, or did. I use the UEFI version of test on the memtest86 site most the time, but I think memtest86+ works ok [20:06] not on amd zen [20:07] but then HP Z400 is intel xeon [20:15] RoyK: sorry been without internet until now. I'll test when I get home. [20:15] tomreyn: and yes it's a Xeon processor :P [20:15] 16.04 worked, 18.04 worked for a while then some kernel update i think torched everything [20:15] i'll have to see if I can't get the actual kernel panic error data [20:18] teward: if you have another machine nearby, setup netconsole to log its stuff there [20:21] RoyK: there's a way to do that even if I can't boot into the isntallers? [20:21] *literally* can't get even into an interactive console [20:22] instant kernel panic whenever I try and get past the splash [20:22] teward: oh - did you try to run that memtest? [20:23] again, not at home yet. [20:23] [2018-10-21 16:15:03] <teward> RoyK: sorry been without internet until now. I'll test when I get home. <-- [20:23] not home yet won't be for another couple hours. On my laptop with my mobile phone hotspot currently. [20:24] will follow up once i am home :| [20:25] o [20:25] ok [21:08] hello what's 3proxy option at fail2ban ? [21:09] i'm trying to block proxy's joining at my website [21:14] 3proxy is apparently a http proxy server product from russia [21:14] that's based on the fail2ban filder.s/3proxy.conf file [21:15] @tomreyn i'm trying to ban somebody that browse my 2.php url page multiple time its like an attack [21:15] actually it does multiple protocols, also socks [21:16] maybe you nee dto write the software so that it can't be easily abused. [21:16] whats the best method to do that [21:16] unauthenticated cleints should not be able to cause high server loads [21:17] he create high traffic and lagg by browsing same page multiple time [21:17] if modifying the application itself is not an option, see what you can do with caching, rate limiting, throwing resources at it. [21:18] do i need to use iptable or fail2ban? [21:23] depends on how you're trying to counter it. [21:24] Checkmate: you could rate-limit NEW tcp port 80 connections from the same origin using iptables [21:25] @TJ- --seconds 60 --hitcount 4 is good ? [21:25] Checkmate: see "man iptables-extensions and the "connlimit" module; it has some very useful examples too [21:30] Checkmate: or there's "haslimit" for rate-limiting the packets or bytes [21:30] grrr, "hashlimit"
