| 02:47.44 | bigdog_ut | ~bigdog_ut |
| 02:47.45 | jbot | well, bigdog_ut is a big dog who turns around three times before falling asleep. in a van down by the river, or wants to be "Mullet-Man" -> professional up front, but one hell of a party in the back. |
| 02:54.30 | wps | with all of the work that was done on my server these past several days... |
| 02:55.03 | wps | someone (not sure who... was probably Matt) changed the name of the server from "anavidesign" to "srv1" |
| 02:55.18 | bigdog_ut | lol |
| 02:55.22 | wps | in /etc/sysconfig/network, it now lists the "hostname" as "srv1.anavidesign.com" |
| 02:55.31 | bigdog_ut | lol |
| 02:55.41 | bigdog_ut | it should have been bigdog |
| 02:55.55 | bigdog_ut | bigdog.anavidesign.com would have been great |
| 02:56.04 | wps | what are the things to be aware of in regards to the server name or hostname... in regards to processing mail |
| 02:56.14 | wps | i know that i did have issues on the last server with the name of the server |
| 02:56.32 | bigdog_ut | yeah make sure you have /etc/hostname set properly and /etc/hosts |
| 02:56.35 | wps | it was just "anavidesign.com" but we were having troubles sending mail, so it was changed to "vserver.anavidesign.com" |
| 02:56.51 | wps | does it need to be "_____.anavidesign.com"? |
| 02:56.56 | bigdog_ut | it needs to be set to what ever the server name is |
| 02:57.04 | wps | where is the server name set? |
| 02:57.14 | bigdog_ut | typically /etc/hostname |
| 02:57.32 | bigdog_ut | but i redhat you can set it in the network stuff as you have pointed out above |
| 02:58.53 | wps | [ /etc/hostname is an empty file |
| 02:59.10 | wps | oh, wait |
| 02:59.13 | wps | that file doesn't even exists |
| 02:59.18 | wps | *exist |
| 02:59.34 | bigdog_ut | yeah it should be set to the server name |
| 03:00.06 | wps | it doesn't exists. Should it be created? |
| 03:02.10 | *** join/#uphpu tierra (tierra@c-24-10-226-227.client.comcast.net) |
| 03:03.01 | bigdog_ut | /etc/hostname yeah |
| 03:03.12 | wps | i wonder why it doesn't exist |
| 03:03.19 | bigdog_ut | redhat |
| 03:03.23 | bigdog_ut | or fedora |
| 03:03.33 | wps | RH/F doesn't use it? |
| 03:03.48 | bigdog_ut | it probably uses the settings in the network |
| 03:03.58 | wps | so i shouldn't create it? |
| 03:04.12 | bigdog_ut | it did in redhat 7.3...that is when i stopped using redhat |
| 03:05.38 | wps | i just checked on a RH 9 box and it doesn't have that file |
| 03:05.43 | wps | i am not going to add it |
| 03:05.59 | wps | anyway, back to my original quesiton |
| 03:06.18 | bigdog_ut | but postfix looks for that file |
| 03:06.26 | wps | it does? |
| 03:06.30 | bigdog_ut | yeah |
| 03:07.02 | wps | okay... i'll give it a whirl |
| 03:07.05 | wps | what should be in it? |
| 03:07.22 | bigdog_ut | if you run hostname from the commandline what does it return? |
| 03:07.58 | wps | srv1.anavidesign.com |
| 03:08.57 | *** join/#uphpu synic|l (~synic@c-67-172-242-219.client.comcast.net) |
| 03:09.05 | bigdog_ut | see hostname should only return srv1 |
| 03:09.12 | bigdog_ut | but is that what you want |
| 03:12.53 | wps | well, that's kind of what I am asking |
| 03:13.24 | wps | does it matter (to mail... because that is what is going to be effected by this the most I think) if it is the format "bertha" or "bertha.anavidesign.com" ? |
| 03:16.44 | wps | someone mind changing the topic back? |
| 03:17.37 | *** topic/#uphpu by bigdog_ut -> Utah PHP User Group |
| 03:17.45 | wps | thanks |
| 03:17.51 | bigdog_ut | wps, it matters that the hostname is correct |
| 03:18.10 | bigdog_ut | or how else is mailing going to get where it needs to go |
| 03:18.21 | wps | so it doesn't matter what it is, as long as it is the same in all three of those files? |
| 03:18.32 | bigdog_ut | and in the dns |
| 03:18.55 | bigdog_ut | the name needs to resolve to the proper ip address |
| 03:19.26 | wps | k... but right now it is set to srv1.anavidesign.com and i am not sending any mail to that domain... but I am sending mail to uphpu.org and several other domains... and that mail is getting through |
| 03:20.33 | bigdog_ut | correct via virtual domains |
| 03:21.23 | bigdog_ut | so if srv1.anavidesign.com is correct then the /etc/hostname would have one line in it with srv1 |
| 03:21.25 | wps | so, sense I am using virtual domains, the server name becomes irrelevant? |
| 03:21.39 | bigdog_ut | no that much more important |
| 03:22.42 | bigdog_ut | someone did not eat his wheaties |
| 03:22.55 | wps | okay... answer me this then... |
| 03:23.08 | wps | why "srv1.anavidesign.com" instead of just "anavidesign.com" |
| 03:23.13 | wps | for for the hostname? |
| 03:23.30 | bigdog_ut | because anavidesign.com is a domain name and not a hostname |
| 03:24.14 | wps | oH! you're saying that whoever (Matt?) set the hostname picked "srv1.anavidesign.com" because a domain called "anavidesign.com" is being hosted on that server? |
| 03:24.28 | bigdog_ut | yep |
| 03:24.32 | wps | that makes sense |
| 03:24.55 | bigdog_ut | did matt configure the network settings on the box? |
| 03:25.02 | wps | so, can i changed the name of the server to something shorter and more personalized, like "tank" ? |
| 03:25.05 | wps | yes |
| 03:25.24 | bigdog_ut | if you dns is set up for it |
| 03:25.52 | wps | i have control over my DNS |
| 03:25.57 | wps | doesn't the DNS just point to the IP? |
| 03:26.10 | wps | (the IP of the server) |
| 03:26.11 | bigdog_ut | the name does |
| 03:26.32 | bigdog_ut | the fully qualified domain name resolves to the ip and vice versa |
| 03:27.09 | wps | hmm... okay |
| 03:27.24 | bigdog_ut | for example...my domain is venticon.com |
| 03:27.32 | bigdog_ut | so i have a server called zeus and gentoo |
| 03:27.45 | bigdog_ut | so their hostnames are zeus and gentoo resp. |
| 03:28.01 | bigdog_ut | but their fqdn is zeus.venticon.com and gentoo.venticon.com |
| 03:28.12 | bigdog_ut | zeus has an alias in dns to www |
| 03:28.26 | bigdog_ut | so i have www.venticon.com that is really zeus.venticon.com |
| 03:29.24 | bigdog_ut | and venticon.com also goes to zeus.venticon.com for http stuff |
| 03:30.26 | wps | okay... so for this server... |
| 03:30.33 | wps | the registrar (godaddy), points the domain name (uphpu.org) at the namserver (everydns.net)... the nameserver then points to the server via it's IP |
| 03:30.55 | bigdog_ut | yeah |
| 03:31.07 | wps | where does the hostname and name of the server fit into that? |
| 03:31.31 | bigdog_ut | it needs to be set so that it has a name associated to the ip address |
| 03:32.21 | wps | and that setting that you are referring to is on the server? or in the DNS? |
| 03:32.29 | bigdog_ut | both |
| 03:35.39 | wps | okay, so here are my DNS settings... |
| 03:35.39 | wps | http://anavidesign.com/temp/dns.jpg |
| 03:35.44 | wps | is that correct? |
| 03:36.16 | bigdog_ut | that looks about right |
| 03:36.45 | wps | taking the domain name and telling it what IP address it belongs too |
| 03:36.47 | wps | *to |
| 03:36.48 | bigdog_ut | but why is the server names anavidesign.com? |
| 03:37.23 | wps | because that is the "main" website on the server |
| 03:37.32 | bigdog_ut | k |
| 03:37.45 | bigdog_ut | did you just show me the uphpu settings in dns |
| 03:37.48 | bigdog_ut | ? |
| 03:37.52 | wps | yes |
| 03:37.55 | bigdog_ut | k |
| 03:38.38 | wps | here's more... |
| 03:38.38 | wps | http://anavidesign.com/temp/dns.jpg |
| 03:38.45 | wps | (refresh) |
| 03:39.01 | bigdog_ut | yeah that is fine |
| 03:39.10 | wps | k... so the DNS is taken care of |
| 03:39.18 | wps | so for the settings on the box... |
| 03:39.22 | bigdog_ut | yeah that is fine |
| 03:39.32 | bigdog_ut | you can also set the aliases in your /etc/hosts file |
| 03:39.41 | bigdog_ut | you have like 4 aliases |
| 03:39.57 | bigdog_ut | you have clients, dev, mail, and www |
| 03:41.48 | wps | so, we have established that the server's name cannot be "anavidesign.com" because there is a domain hosted on the server of the same name, but... |
| 03:42.08 | wps | is there any difference between "srv1.anavidesign.com" and just "edward" ? |
| 03:42.14 | wps | for the server name? |
| 03:42.25 | bigdog_ut | yeah edward has no domain |
| 03:44.00 | wps | ah... so the server name has to have a domain associated with it? |
| 03:44.19 | wps | so, something.example.com is the standard way to do it? |
| 03:44.25 | bigdog_ut | yeah...becuase of how names work |
| 03:45.10 | wps | alright... sorry for that taking so long, you probably think that I'm an idiot |
| 03:45.22 | bigdog_ut | no...not really |
| 03:45.25 | bigdog_ut | :)( |
| 03:45.54 | wps | so, if I wanted the casual name of the server to be "edward" instead of "srv1", I would change it to "edward.anavidesign.com" ? |
| 03:46.03 | bigdog_ut | dont worry i do this all day at work...i explain complex practices to management |
| 03:46.17 | bigdog_ut | yep that is correct and modify your dns |
| 03:47.09 | wps | wait... you just lost me |
| 03:47.28 | wps | "srv1.anavidesign.com" is the current name, but it isn't in the DNS anywhere |
| 03:47.55 | bigdog_ut | then dont access edwards.anavidesign.com via dns |
| 03:48.18 | bigdog_ut | dont try and resolve it via the name cause you have no ip address assigned to it |
| 03:50.01 | wps | okay :) |
| 03:51.39 | bigdog_ut | does that all make sense..sometime i ramble |
| 03:51.58 | wps | the last two lines didn't exactly |
| 03:52.35 | bigdog_ut | you cant type in edwards.anavidesign.com into a browser and have dns resolve the name if there is not one in the dns |
| 03:52.35 | wps | so, you're saying that it's okay to have the server name be "srv1.anavidesign.com" or "edward.anavidesign.com" as long as I don't try accessing it via DNS... but I am not sure when I would |
| 03:52.46 | wps | okay |
| 03:53.01 | wps | you just saying that the name that I pick for the server can't ever be used for a sub domain? |
| 03:53.35 | bigdog_ut | nope |
| 03:53.51 | bigdog_ut | you can have it for a subdomain too |
| 03:53.51 | wps | dang... i was hoping you'd say yes... 'cause then it'd all make sense |
| 03:54.15 | bigdog_ut | the name is just how a human representation of the ip address |
| 03:54.34 | bigdog_ut | it is easier to remember localhost than 127.0.0.1 |
| 03:55.15 | bigdog_ut | or www.yahoo.com than 66.94.230.47 |
| 03:56.11 | bigdog_ut | if i ping www.yahoo.com i get a response from server: p16.www.scd.yahoo.com |
| 03:56.38 | bigdog_ut | the hostname is p16 and the domain is www.scd.yahoo.com |
| 03:57.22 | wps | alright... that makes sense |
| 03:57.36 | wps | so were you just saying that I can have both the server named "edward.anavidesign.com" and a sub domain named "edward.anavidesign.com"... AS LONG as I also have my DNS set to point the sub domain to the IP of the box? |
| 03:58.15 | bigdog_ut | yeah if you like but it sounds like you are talking a subdomain in the terms of a webserver |
| 03:59.30 | bigdog_ut | bbs |
