问题 I have just set up a cloud using cloudstack 3.0. I have installed its management server on system having IP address 10.129.34.15, which can be accessed in browser using following url: "http://10.129.34.15:8080/client" Now I made an entry in DNS server as follows: 10.129.34.15:8080 maps to www.cse.iitb.ac.in/rcloud So I can access the cloudstack interface in browser using: http://www.cse.iitb.ac.in/rcloud/client Now when I use "http://www.cse.iitb.ac.in/rcloud/client" and I enter my username

Tomcat with 1-way and 2-way SSL

由 落花浮王杯 提交于 2019-12-10 21:18:15
问题 I have a service A that uses 1-way SSL and also 2-way SSL to make secure requests to service B. 1-way SSL is specified by Tomcat config, I provide keystoreFile, keystorePass, enable SSL, etc. 2-way SSL is implemented using JSSE on the client (service A). I know this could be done similarly in Tomcat server.xml too (example is here: http://blog1.vorburger.ch/2006/08/setting-up-two-way-mutual-ssl-with.html). Part of my 1-way SSL Tomcat configuration: <Connector port="securePort" scheme="https"

Validate FQDN in C#

由 ￡可爱￡侵袭症＋ 提交于 2019-12-10 14:43:08
问题 Does anyone have a Regular Expression to validate legal FQDN? Now, I use on this regex: (?=^.{1,254}$)(^(?:(?!\d+\.|-)[a-zA-Z0-9_\-]{1,63}(?!-)\.?)+(?:[a-zA-Z]{2,})$) However this regex results in "aa.a" not being valid while "aa.aa" is valid. Does anyone know why? 回答1: Here's a shorter pattern: (?=^.{1,254}$)(^(?:(?!\d+\.)[a-zA-Z0-9_\-]{1,63}\.?)+(?:[a-zA-Z]{2,})$) As for why the pattern determines "aa.a" as invalid and "aa.aa" as valid, it's because of the {2,} - if you change the 2 to a 1

Translating NETBIOS domain into a FQDN (Fully Qualified Domain Name)

由 与世无争的帅哥 提交于 2019-12-06 04:04:22
问题 In short - How do I translate a NETBIOS domain to a FQDN ? Details: Assuming I'm in domain A and I have user credentials for domain B which has a trust relationship with domain A (I can authenticate the credentials). How do I get domain B's FQDN when all I have are the credentials of some authenticated user from that domain, including the netbios domain name? I'm coding in C# but a COM/WMI/Win32 solution would be welcomed as well. 回答1: This probably isn't optimal, but it look like you could

Ip address to NetBIOS/FQDN name in Java/Android

由 自闭症网瘾萝莉.ら 提交于 2019-12-03 15:17:58
问题 given the ip address of a computer on the same network of my Android device, i have to find its NetBIOS/FQDN name ... is there any "clean" solution to accomplish this with the Android SDK and generally speaking in java ? Obviously InetAddress.get*HostName does not return the NetBIOS name :) 回答1: You can use JCIFS open source library. InetAddress addr = NbtAddress.getByName( "hostname" ).getInetAddress(); works both ways, ip address to hostname and vice versa. 回答2: Actually, the code provided

Redirect URLs with FQDN (dot after TLD) to equivalent with PQDN

由 断了今生、忘了曾经 提交于 2019-12-02 01:09:40
问题 Many websites can be accessed with a FQDN (i.e., appending a dot to the TLD): https://www.ebay.com./ https://www.google.com./ https://www.reddit.com./ https://stackoverflow.com./ https://en.wikipedia.org./wiki/Main_Page Some sites can’t be accessed that way, but I can’t find an example right now.¹ ² Is it possible, within a .htaccess file, to redirect all variants with the dot suffix to the variants without? Ideally with a "wildcard" rule, so that you don’t have to list the domains explicitly

Configuring FQDN for GCE instance on startup

由 蹲街弑〆低调 提交于 2019-12-01 09:18:21
I am trying to start a google compute engine (GCE) instance with a pre-configured FQDN. We are intending to run an application that is licensed based on the contents of /etc/hosts. I am starting the instances using the Google Cloud SDK utility - gcloud. I have tried setting the "hostname" key using the metadata option like so: gcloud compute instances create mynode (standard opts) --metadata hostname=mynode.example.com Whenever I log into the developer console, under computer, instances, I can see hostname under "Custom metadata". This appears to be a new, custome key - it has no impact on
