Flushing DNS Cache

location: ubuntuforums.com - date: October 29, 2010
I have been advised to flush the DNS cache to solve a problem I am having with certain websites. To do this I was advised to see the web pagehttp://www.techiecorner.com/35/how-t...x-windows-mac/. The instructions there tell me: To flush the DNS cache in Linux, restart the nscd daemon:- - To restart the nscd daemon, type /etc/rc.d/init.d/nscd restart in your terminal - Once you run the command your linux DNS cache will flush. However when I try that in the Ubuntu terminal I get: bash: /etc/rc.d/init.d/nscd: No such file or directory And attempting to find file "nscd" anywhere else has been fruitless. How does one flush the DNS cache in Ubuntu? Release 8.04 (Hardy) Kernel 2.6.24-16-Generic Gnome 2.22.1 Browser3.0b5

Flushing linux DNS from JAVA

location: linuxexchange.com - date: August 6, 2013
We have a RC module that gets dropped into our cloud servers during hot deployment. To that end, I need a way to flush the DNS programmatically from within JAVA. The best solution that I can think of is to just have java fire an external shell script, however I'm not having any luck. I've tried the "normal" procedures to an avail: 1) restarting nscd service (not installed in these servers) 2) /etc/init.d/networking restart (no effect) 3) /etc/init.d/dns-clean start (no effect) Anyone have any more suggestions? (NOTE: this is a re-word of a previous post that must have been determined as being "non-development" related...) TIA

Moving from CentOS 5.7 to Ubuntu 10.04 for LAMP, DNS, Murmur, Minecraft server

location: ubuntuforums.com - date: September 30, 2011
I've been using CentOS 5.X as a LAMP server for a few years now. I've been considering switching to Ubuntu 10.04 because it seems to have more packages that I use than CentOS does. I'm at the stage where everything I know about running the server is from writing down things I've learned from scouring the net when a problem comes up. I've done things like enable test repos and built programs from source to get things running (like murmur and ICE) when I know ubuntu already has packages available. I've been wondering how much of a security or stability risk my CentOS server is now. For this reason I've been thinking the smart thing to do may be to swap to using Ubuntu and just learn the differences between the two OS's. I'd like to know what others' opinions are on this.

Samba4 : sambatool dns add

location: linuxquestions.com - date: May 5, 2013
I have set up Samba4 on Ubuntu Server 13.04 64bit. I have tried adding a Windows 7 Client machine which is set to resolve DNS from this server (using Samba's internal DNS Server) but I get an error message stating that the SRV record was queried successfully yet the domain controller could not be found. It states that common reasons for this are that there are no A records for the domain controller. I know that the samba-tool command needs to be used as such: samba-tool dns add <server> <zone> <name> <A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data> If my server is called server01 and my domain is example.local and the IP address of the server is 192.168.1.1 what would the command be that I would need to enter in to setup an A record for my SERVER01 host. (Providing that an A record is what I need to resolve this).............

11.04 DNS errors

location: ubuntuforums.com - date: May 12, 2011
I have recently upgraded to the new ubuntu 11.04 but am having problems with the internet. Often When I try to access a website it takes a long time (5-10 minutes) to load even google, and sometimes I just get the following error message: This web page is not available The server at google.com can't be found because the DNS lookup failed. DNS is the web service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Chromium from accessing the network. Here are some suggestions: Reload this web page later. Check your Internet connection. Reboot any routers, modems or other network devices that you may be using. Check your DNS settings. Contact your network administrator if you're not sure what this means. Try disabling DNS prefetching by following these steps: Go to Spanner m

Squid/DNS Intermittent Issue

location: linuxquestions.com - date: July 23, 2005
squid 2.5.STABLE10 (localhost) on slackware 10.1... i am getting an intermittent/sporadic squid DNS error when surfing the web (through squid)... it will happen with known good URLs and when it happens the "outage" only lasts less than a minute... the URL works fine if accessed directly without the proxy... the error message is usually the classic squid "name error... the cache was unable to resolve, blah blah blah"... the squid access log shows that there's TCP_MISS/503 errors when the problem occurs... AFAIK everything looks as if it was an invalid URL during the outage - but once again, the URLs are known good and perfectly accessible using non-squid means at the exact same moment in which squid is giving the dns error... as for troubleshooting, i've played with the conf file a lot, and recompiled squid several times, stripping it down a little more each time, tinkering with the configure options - the problem is not affected... BTW, i've compiled squid

dns 323 stopped mounting samba/cifs error 6

location: ubuntuforums.com - date: November 22, 2008
I've had a DNS 323 mounted to the filesystem with cifs and fstab for 6 months. the NAS has firmware version 1.05 and i'm running hardy 8.04. Lately I've been having issues where I get "Permission denied" issues when trying to unpack .rar files downloaded with the built-in bittorrent client on the NAS. These stick around a while then eventually go away with no explanation. Today my system stopped seeing the NAS. I can ping it, and I can access the admin website and FTP to it, but I cannot connect to it as a windows share or mount it. My XBOX still sees it too. I've tried tweaking the fstab line, mounting from the command line using smbmount, mount.cifs and mount commands. It previously gave me permissions error with mount error 13. I restored factory settings on the NAS and reset all the user privileges from the admin page. Now it gives me :~$ smbmount //140.180.129.69/Volume_1 /media/NAS -o user=dstrife,pass=XXXXX 0 0 retrying with upper case share name mount er
