Hi

I am a student of third year computer engineering and i am interested to do Clustering in Linux can to give me a favour to guide me to do what and how,

Thanking you

LVSM is a GPL'd management package being developed here at Penguin Computing to aid in the setup and admistration of LVS based clusters. What does LVSM offer? - Level 4 switching with LVS - High Availabity with heartbeat - Service Level monitoring with mon - Web based gui - On the fly configuration - Cluster Statistics reporting The LVSM homepage is at http://lvsm.theory.org What can lvsm do now? LVSM can: - inspect cluster resources such as vips and nodes, - add / remove / configure vips dynamically - show network statistics for vips and hosts All of this is done through a web based gui for easy admistration. As this is the initial public beta release of LVSM we are mostly looking for feedback at this point. We do not recommend the use of LVSM in production systems at this point in time :) Please send any questions / feedback / complaints to the lvsm mailing list at lvsm@theory.org.

Ok, I just downloaded the code, extracted it and had a 15 minute look at it (random stuff I would complain about): o It's very difficult to understand the code: - indentation is only 2 chars - c++ , just kidding :) [very advanced c++ for me!] - some prototype definitions are missing or should go into *.h files e.g, Select.cc is ugly as it gets :)) o Why do you use the ``ipchains -L -vnx --line-numbers'' approach to get the statistics? [ipchains_stats.cc]: if(use_chains) ipch = popen("/sbin/ipchains -L -vnx --line-numbers", "r"); else ipch = popen("/sbin/iptables -L -vnx --line-numbers", "r"); fgets(buf, 4096, ipch); keep_going = true; char * ptr = NULL; int c = 0; while(keep_going) { if(strstr(buf, "Chain ")==buf && strstr(buf, chain) - buf == 6) { fgets(buf, 4096, ipch); fgets(buf, 4096, ipch); while(strstr(buf, "Chain")!=buf) { if(num_rules == c) { if(use_chains) { ptr = strchr(buf, '-'); if(!ptr) { l->log(LL_WARN, "couldn't find str '-' in buf '%s'\n", buf); } } else { ptr = buf; // aye aye aye.. /\d+[^\d+]\d+[^\d+]\d+\s+/ while(isdigit(*ptr)) ptr++; while(!isdigit(*ptr)) ptr++; while(isdigit(*ptr)) ptr++; while(!isdigit(*ptr)) ptr++; while(isdigit(*ptr)) ptr++; while(isspace(*ptr)) ptr++; } break; } c++; o very interesting code, but very CPU intensive! I have 15000 iptables rules, and all together 5000 concurrent connections -> iptables -L -vnx is a pain in the ass, that's why we have /proc/net/ip_masq/vs_stats. o you plvsd daemon is not really portable to other architectures or at least it takes quite some time: You seem to use the pthreads in a way Plan9 or HP/UX would not support them. You assume, everybody is running Linux as real servers. o not everybody has the pidof(8) installed on the system, but everybody for sure has ps. Generally, make sure you use basic Unix tools and not for example distro-specific tools. just my 2 dimes, Roberto Nibali, ratz -- mailto: `echo NrOatSz@tPacA.cMh | sed 's/[NOSPAM]//g'` Linux-cluster: generic cluster infrastructure for Linux Archive: http://mail.nl.linux.org/linux-cluster/
