Search Again: Load Balancing WWW, ftp breaks From: Neil Ticktin Date: Tuesday, January 22, 2002 Time: 6:54:29 pm So, we've been running load balancing records recently -- and we're pretty pleased with that setup. So, somewhat simplified a DNS set up is looking like this: mactech.com IN NS ns1.xplain.com. mactech.com IN NS ns2.xplain.com. mactech.com IN NS ns1.tennis-warehouse.com. mactech.com IN MX 10 mail mactech.com IN MX 30 mail2.xplain.com. mactech.com IN MX 91 mail3.xplain.com. mactech.com IN MX 95 mail.tennis-warehouse.com. mail.mactech.com IN MX 10 mail mail.mactech.com IN MX 30 mail2.xplain.com. mail.mactech.com IN MX 91 mail3.xplain.com. mail.mactech.com IN MX 95 mail.tennis-warehouse.com. mail.mactech.com IN CNAME mail.xplain.com. www.mactech.com IN CNAME thirdparty.www.xplain.com. mactech.com IN A 198.172.82.18 ftp.mactech.com IN A 198.172.82.23 where thirdparty.www.xplain.com is set up as a load balancing record defined as: TTL: 60 Interval: 60 Hostlife: 180 Protocol: HTTP 198.172.82.18 1 206.24.92.210 1 65.88.5.67 65534 So, the problem is that while http access works great in this scenario, if I go to use ftp access to a machine name is load balanced (e.g., to upload files to a web server) it doesn't work at all. In Fetch, for example, I get a "The connection was refused" error message. Interestingly enough, if I ftp to mactech.com instead of www.mactech.com -- that works JUST fine. It is definitely a result of the load balancing record being involved. And, I have other examples where instead of www.yyy.com being set up as a CNAME to a load balance record, www.yyy.com is just directly a load balance record itself. I can't believe that I'm the only one that would want to ftp upload files to a load balanced web server. Has anyone else see this? Is there a solution other than to have people ftp to mactech.com instead of www.mactech.com? (BTW: ftp.mactech.com is a completely different machine.)
