问题 bbs.example.com I referred to the domain name knowledge on Wikipedia, and have read through the page, but I still don't know what is a second-level domain name? The page says com is a TLD (Top Level Domain), and the TLDs are the highest level of domain names on the Internet. It says. bbs.example.com is a third-level domain name? But someone told me bbs.example.com is a second-level domain name. .com is the TLD, not the domain name. Which is right? Thank you. 回答1: bbs in bbs.example.com is a

问题 I just started up an Azure server and have been trying to access it for a while and am having a hard time doing so. I installed zPanel on my 12.04 Azure Ubuntu server (like cPanel: Apache, MySQL, PHP, etc) and made sure Apache was working and pointed a domain to the server IP and gave it to zPanel's installer to config. I tried accessing the server through direct IP, through the domain and even pinging it. I keep getting Request timed out . I'm using the "Resource Manager" in Azure and can't

问题 I am trying to figure out how to point my domain, which is registered with 123-reg to my heroku app. Currently, when I check whether the steps I have taken have worked, I get an error that says: Host www.example.com not found: 2(SERVFAIL) Heroku has instructions for GoDaddy. I use 123-reg. 123-reg don't have any support for heroku but they do have instructions for adding CNAME records to my DNS. I've followed them. I made three CNAME entries (and removed all A records as it appears that

问题 My understanding is that both JAAS and SQL Server can be configured to use kerberos in a domain environment, with an active directory server. My understanding that JAAS gets the user credentials from the user or from a file at the time of the connection - asks the directory server for a ticket, and presents that to the server. Where does the SQL Server Driver get its kerberos ticket from? (as it seems to be able to obtain creditentials from the users existing login). Does it get the user

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I bought domain www.mydomain.com from godaddy.com. I hosted it at www.000webhost.com (free web-domain-hosting site). I created a subdomain subdomain.mydomain.com through ccpanel of 000webhost.

问题 So I have found this error log PHP Warning: unpack(): Type n: not enough input, need 2, have 0 in {{file}}{{line}} the said file and line contains this code: $answerHeader = unpack('ntype/nclass/Nttl/nlength', $answerHeaderBin); This is part of a code which makes a query on a DNS. My issue is that I don;t know how to debug this. If I try to dump the before mentioned header the information is correct. I tried unpack() with no arguments and it just returns false with no errors. So I guess, my

问题 I am new to WP multisite environment. I want to setup multisite in my local Ubuntu 14.04 environment. I already have localhost for my main site configured as carbazarlocal.com and its running OK. When I go to Tools > Network Setup I can see two options - Sub-domain and Sub-directory.

问题 Suppose there are 2 computers on same network, named com1 and com2. On com1, if I call Dns.GetHostEntry("com2") surely enough, it returns only 1 ip address, like 192.168.1.2, which I could use it to communicate with com2. However, if I call Dns.GetHostEntry("com1") It will return all ip addresses (192.168.1.1(the one I want) as well as other addresses like 169.254.100.50 (vm address, I need to filter this out)) The question is, how can I get a unique "real" ip address for com1 in this case?
