does anyone know of a good site/book/guide to learn about linux web server administration?
and also how do you find the your own nameserver numbers? would that just be the IP of my web server?networking isn't my forte, but i do intend to learn with this project.
Does anyone have some material about statistics using ubuntu / linux server, or a text which generally describes the ubuntu server?I need urgent, i'm writing specialization work about administration apache and ftp server on ubuntu 10:10 server, so I need something for the conclusion.
View 7 Replies View RelatedI want to make a FTP server with web frontend for administering it, eg creating users, groups, setting which directories users can access and so on.I found some web frontends for proFTPd, like those URL... , bus all of them seems to be very old and doesn't work nicely. I tried ProFTP Administrator and it won't work.Do you know some solutions to manage ftp server users, groups, permissions over web? Or by some frontend program.

I have a small webserver running ubuntu server 10.4. It runs fine except after every reboot, I get DNS errors. I have to manually edit /etc/resolv.conf to add:
Code:
nameserver 192.168.1.1
The address of my internet gateway on my LAN. Obviously I am ignoring the warning in resolv.conf that this will be overwritten.
Like many others I'm running into some reverse lookup issues with SSH. Setup is as follows:
localnet setup
myserver - 192.168.0.x
myworkstation - 192.168.0.y
[Code].....
nslookup tests show that my reverse lookup is functioning correctly. However, if I use "myworkstation" to connect to myserver.mydomain.com using an external nameserver SSH says: "Address 84.162.xx.yy maps to myserver.mydomain.com, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!"
On myserver the /etc/hosts has the internal address for the server which seems the normal way to go to me. Changing this to the servers external address solves the issue.
Apparently a connection originating from myworkstation arrives from/with my external address, and when its reverse is checked by the server it apparently finds its own internal address for that name in /etc/hosts before doing a nameserver query and thus concludes that internaladdress <> externaladdress which gives the error.
Is there any way to have the server check external DNS before /etc/hosts? Another solution would probably be running an internal DNS, so myworkstation doesn't connect through the 'outside'.
How can I have /etc/resolv.conf point to my router address as the nameserver nameserver 192.168.1.1
instead of picking up the ISP's DNS servers and using that as the nameserver entries? Reason being I have more than one ISP account, and when I change I do not want to have to remember to restart the networking service. because i often forget.

I use red hat Es 5.5 64 bit.. I find the item nameserver in resolv.conf cannnot be saved. Everytime ,reboot or restart the netwrok service . The data in resolv.conf will be removed and clear . I need to edit it again . I also try to add DNS1=XX.XX.XX.Xx in ifcfg-eth2 but the same problem. in it , the resolv.conf is still need to edit every network service restart . So, how to save the resolve.conf about nameserver forever ??
[root@vls etc]# cat resolv.conf
# Generated by NetworkManager
# No nameservers found; try putting DNS servers into your

My configuration: CentOS in a VPS environment, I have 2 static IPs at my disposal.I'm having trouble setting up my nameservers. I've registered the nameservers with my registrar and supplied the GLUE records, however my registrar has not yet applied this information into the DNS zone, because my nameservers fail to generate a response on port 53.DNS check says the following about my nameserver address:Checking SOA records for domain. Domain server is not answering to UDP requests on port 53. Possible problems: A firewall is blocking port 53, server is down, server is not running software for handling dns requests.So the only two possibilities I see is that my port 53 is somehow blocked or not properly set to accept and send the correct traffic or that I've misconfigured BIND.
View 2 Replies View RelatedI am trying find files in a directory that contain numbers. I have tried ls /etc *[0-9]* but that doesn't work. If I cd to /etc and run ls *[0-9]* it almost works but it also includes results from within files. My last thought was to try: find /etc [0-9] -type f but this does not work either. My second problem is that I am trying to get list of files in a directory that were changed less than 10 hours ago, using grep, while leaving out directories. I am completely stuck with the second problem.

How do I know the reply was from caching-nameserver, master nameserver or slave nameserver in BIND DNS.? Can I trace the nameserver that replied my dns query? Like I have a master nameserver, a slave nameserver and a caching nameserver in my network. Is it possible to know that which of these servers replied my dns query? Also can i trace back that replying server exactly?
