We’ll have a new course in FMI – different case studies of the system and network administration with Linux. The course is every Thursday in hall 325 of FMI from 19:00 (some days it might be from 18:00, we’ll notify the people beforehand. We have a site for the course<\/a>, the current list of teachers is me, Boyan Krosnov, Marian Marinov and Nikolay Nedyalkov (I’ll also talk with Vlado Karavelov on the last cases with the hardware).<\/p>\n

Here’s the conspectus:<\/p>\n

00– architectures used in the case studies
\n01– recovery – building recovery systems
\n02– config management – svn\/git
\n03– basic router – firewall, routing, openvpn, nat, bridge, bonding
\n04– policy routing\/multihoming+NAT
\n N links, incoming DNAT, connmark
\n N links, outgoing SNAT, balancing
\n N links, load balancing\/connection (2 subcases)
\n05– traffic control
\n latency optimization
\n fairness
\n deep packet inspection (layer 7 filtering)
\n06– dynamic routing
\n OSPF
\n BGP
\n VRRP
\n anycast
\n07– heartbeat failover
\n drbd\/iscsi\/FC
\n OCFS
\n application tracking (mysql)
\n08– load balancing
\n DNS loadbalancing
\n layer 4 loadbalancing (iptables\/LVS)
\n layer 7 loadbalancing (squid\/tomcat)
\n09– network troubleshooting
\n path mtu
\n layer 2 cases – unknown unicast flooding, mac address table problems
\n bgp problems – youtube problem, long prefix problem, uRPF
\n filter tracking (hping, tcptraceroute)
\n asymetric routing problems (looking glass)
\n10– system\/kernel debugging
\n sigsegv tracing (gdb, ulimit), attaching gdb to live process
\n strace, ltrace (limitations) – ffmpeg case, libdb exim case
\n11– optimization
\n dynamic content\/apache
\n static content
\n DB optimizations – indexes, query optimizations, explain
\n select * from pesho where pesho.a in (select gosho from table2);
\n hardware recommendations – db, router, storage, app server, voip server<\/p>\n","protected":false},"excerpt":{"rendered":"
