General :: Host Command And Web Browser's Don't Accept Hosts.conf Order
Mar 4, 2011
Why does ping see audit.median.hu as 127.0.0.0, and why does host -t a audit.median.hu see it as 193.68.35.149? audit.median.hu is just an example site [hosts ads, etc.]
I just have a caching nameserver on my Fedora PC:
I configured my DNS server addresses in the Network-Manager Applet: 127.0.0.1, 8.8.8.8
Even with Wireshark, I can see it:
So the big question: Why don't the host command or my web browser recognize that I have modified audit.median.hus IP address?
I have an log monitoring application that is listening on port 514 to receive events only from certain hosts.In order to control this,I've tried set up iptables to define those hosts that are allowed to this application. Here is an example of the script that contain the commands:
I have installed CentOS 5.4 machine named test.example.com (192.168.1.1)File /etc/hosts contains:127.0.0.1 test.example.com test localhost.localdomain localhostI have read that the loopback addres should not be assigned to host name,only to localhost and the host name should be assigned to 192.168.1.1, like this:127.0.0.1 localhost.localdomain localhost192.168.1.1 test.example.com testIs there any reason why it should be one or another way?
I've been scanning the apache2 docs for the past few days and have not come up with an answer my following issue:
In my httpd.conf file, at the very end, I have the line
Include conf/vhosts/vhost_*.conf
However, when I run apache checkconfig or try to start apache, it gives me the error:
httpd: Syntax error on line 993 of /etc/httpd/conf/httpd.conf: Could not open configuration file /etc/httpd/conf/vhosts/vhost_1.conf: Permission denied
It appears as if the Include line is correct - in terms of it grabbing the first virtual host conf file. However, I'm confused on the permissions. the /etc/httpd folder is owned by root:root, as are the subfolders. As a test, I chown'd the conf/vhost folder combination and all the vhost files to apache:apache to see if that made a difference, and it appeared to make no difference at all. The log files don't contain anything (assumed because apache isn't starting). If I place the contents of the vhosts in a singular vhosts.conf it works - with the permissions set to root:root. I'd like to avoid having to use one vhosts conf for the configuration I'm trying to achieve - as it would make my life a lot easier.
I am trying to upgrade my system from 7.04 to a current version. I now face the known problem that my machine tries to download everything from archives.ubuntu.com although it has all been moved to old-releases."If you have this problem, you could change your /etc/host file to point archive.ubuntu.com to old-releases. Do this by running host old-releases.
ubuntu.com | grep address | awk '{print $NF" archive.ubuntu.com"}' | sudo tee -a /etc/hosts."
I have tried typing that information into the command line, with no success. I opened the /etc/hosts file in emacs (using sudo) but did not see an obvious place to impliment the fix.
I want to give access to a student to a server in order to make repeated trials of traceroute to different hosts. We have realized that it is preferable to use the -T option, as it sends TCP packets that are less commonly blocked by firewalls. However, this option is only available to superusers, and I don't want to grant the student such privileges.
I've recently been asked to setup our FTP server to accept connections from a remote host. They sent me a file "id_dsa.pub" with instructions to add this key to the xfer user.
dammit... all that typing and I hit the wrong "submit" button. *sigh*
Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
I am using denyhosts on a server so in a config file/etc/denyhosts.confthe following value is setQuote:DENY_THRESHOLD_INVALID = 3which as per their configuration file saysQuote:
DENY_THRESHOLD_INVALID: block each host after the number of failed login # attempts has exceeded this value. This value applies to invalid # user login attempts (eg. non-existent user accounts)
One our client has recently installed Red Hat 5 X64 on the hosts, each host has 2 Qlogic HBA's, which are connected to IBM DS4800.RH5X64 has MPIO built in or do we need to download? If download is required, pls provide link.
I am unable to start apache on my linux machine with following errors Starting httpd: Syntax error on line 117 of /etc/httpd/conf/httpd.conf: Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration I am using CentOS5 with apache version httpd-2.2.13
I'm not sure if this is best done in Perl or Bash. I'm thinking surely someone else has created something close to what I'm looking for. The results of the script would be that someone would kick off "linux_hosts.sh" r whatever you want to call it, then a top "folder" of options (with hosts contained within each of these top menu choices), then, based on which number corresponds to that top level, they're presented with a set of linux hosts that are relevant to that top level name. Example:
$ linux_hosts.sh 1. VMware hosts 4. Private Domain 2. ESX servers 5. Red Hat boxes
I have one distro installed, LILO as the boot loader, and i wonder if it's possible to duplicate the lilo entries with an option which executes some script or command during, or after the boot.Actually, i installed a Slackware + autolaunching virtual machine, but i have two VM, so i need to autolaunch one of them. May i choose it from the very beginning ?
How do I setup a host computer to accept display from laptops in a group of laptops?
I have a group of people each set to manage a specific task. I have a projector in the middle of the room hooked up to a computer. How can each user push their screens to the host computer? All computers are on a lan
I am running an application that requires use of my /etc/hosts file. In it, I have my machine name and its LAN ip address. The program creates a service on a specific port, then attempts to connect to it based on the host name. So my hosts file has to be correct.I added the nameservers to resolv.conf and now my application will not run. My guess is that the computer is checking the name servers first, timing out then checking the hosts file.Is there a way I can tell the system to check the hosts file first, then DNS. I thought it should behave that way by default, but it does not appear to.
I want to run a linux command with apache through web browser and that's is not working. and it's working properly when I execute this command through terminal, where is the problem?
NOTE: apache have the privileges to execute the command
Since I installed Chromium-browser, it has been set as the default system browser (don't know why, don't know when, maybe I clicked accept somewhere without paying attention). Now every web link I click (for example from Skype), Chromium will be opened instead of Firefox.
How can I make Firefox my system default browser?
I need to set this preference using the command line.
Is it possible to use cd command to navigate back and forward (like browser)?. Something similar to cd - but it only swaps current and last location. I know I can push dir on stack, it would be great to use cd -> and cd <-, though.
I have a problem, I set a Debian server with no GUI. I have set http_proxy and I want to add ignored hosts for local address like I did in Ubuntu(System->Preference->Network Proxy->Ignored Hosts).How can I do that in Debian (with no GUI only bash) like I did in Ubuntu with GNOME Desktop?
I have the following command:ssh $USER@$HOST "ls /ops/pkg/ec/`grep "PKRTS" /ops/pkg/ec | awk '{print $1}'`* > /tmp/tmp_file"What the above SHOULD do..is, ssh to the host then execute the command.The command should first execute the grep and awk between the back ticks, and generate a file name, then ls using that filename* and write that data to a temp file.However, it executes the grep and awk before even SSH'ing and the command that goes to the server is simply an "ls /ops/pkg/ec/* > /tmp/tmp_file" since the grep and awk return nothing on the local machine.
