hostname

I use my remote MySQL database during long time. But today I suddenly have found that I cannot connect to the database. I have got an error. "Can't get hostname from your ip address". I haven't changed anything in MySQL settings. What's the problem? Just add below in my.ini or my.cnf . [mysqld] skip-name-resolve Linux: Otherwise, start MySQL server with the following flag: sudo service --skip-name-resolve For more information: http://dev.mysql.com/doc/refman/5.0/en/host-cache.html I've got the same error message on windows. I found my problem is the local server host file. Check the localhost

I am wondering what is the maximum number of characters for a host-name in a Unix system. In addition is there any defined variable that can be used in Unix programming to call that number? (i.e. number of characters allowed for a host-name). I am programming in C. You can usually type: getconf HOST_NAME_MAX In addition, you can generally include limits.h to your application and read the value of the define. While the POSIX standard says it is guaranteed not to exceed 255 bytes, that does not necessarily mean that each implementation will adhere to that. man gethostname on your platform to get

Assuming that a local Python-Script is running a webserver. Is there any way to set an alias, so that http://localwebapp/ equals http://localhost:1234/ ? Edit: Or at least http://localwebapp:1234/ equals http://localhost:1234/ ? When the browser sees http://localwebapp/ it first tries to determine the IP address of localwebapp . If this succeeds, the browser establishes a TCP connection with that host, using a specific port (which is 80 for HTTP, unless some other port is mentioned in the URL). Resolving localwebapp to an IP address does not take port information into account, so pointing http

I thought ServletContext might provide a method. Does the getAttribute() method of ServletContext provide any help i.e. is there an attribute name (maybe "host", "port") that will be of help. The reason for this is I want my application to run wherever it is deployed, and at one point I have to allow a user to click a link that points to a location on the file server. Hence I need to reference by the host and port and cannot use an internal reference. Everyone ServletRequest.getServerName(...) ServletRequest.getServerPort(...) The ServletRequest object that has been passed to your doGet, or

From what I have seen, in the MSDN documentation and in other questions here on SO, there are four ways to get the local machine name. Environment.MachineName; System.Net.Dns.GetHostName(); System.Windows.Forms.SystemInformation.ComputerName; System.Environment.GetEnvironmentVariable("COMPUTERNAME"); Is there a differnece in what they methods will return or will they all return the exact same thing all of the time? Note: I first saw the list in this post: How do I get the local machine Name? EventHorizon Environment.MachineName and System.Windows.Forms.SystemInformation.ComputerName are

Following up to Regular expression to match hostname or IP Address? and using Restrictions on valid host names as a reference, what is the most readable, concise way to match/validate a hostname/fqdn (fully qualified domain name) in Python? I've answered with my attempt below, improvements welcome. Tim Pietzcker import re def is_valid_hostname(hostname): if len(hostname) > 255: return False if hostname[-1] == ".": hostname = hostname[:-1] # strip exactly one dot from the right, if present allowed = re.compile("(?!-)[A-Z\d-]{1,63}(?<!-)$", re.IGNORECASE) return all(allowed.match(x) for x in
