Ubuntu Networking :: Way To Have / Etc / Hosts File Re-read Sooner?
Feb 28, 2011
I often manually add a troublesome domain (e.g., advertisements, fake virus alerts, etc.) to my /etc/hosts file on Ubuntu 10.04 Lucid; but the effect isn't immediate.My hosts file is already fifteen thousand lines long (having combined all the hosts files I could find on the net, including the MVP one); but I still, almost daily, find a new irritant to add to my /etc/hosts file.My problem is I do not understand WHEN the /etc/hosts file is next read after a change.I've been rebooting to make sure the hosts is re-read; but there must be a simpler way.My question:
- WHEN is the /etc/hosts file reconsidered in Ubuntu?
- Is there a way to have the /etc/hosts file re-read sooner?

I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?

Probably an easy (which means stoopid) question...I am trying to reroute a website using my hosts file so that it matches my servers certificate file for testing without effect dns and the live site.When I went to edit my /etc/hosts file it is non-existent. I have, I am assuming in it's place, hosts.allow and hosts.deny. Can anyone explain why I do not have a hosts file?

Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.

Is it possible to have different /etc/hosts file for different network connections without having to go in and change it every time? The why: I have dyndns and port forwarding to get to my desktop. My laptop is sometimes on the same network, and sometimes not. Also, sometimes the dyndns doesn't update properly, or the outside connection is down, but I want to get to my desktop (and I'm too lazy to walk up the stairs). I'd like to be able to keep one set of bookmarks, ssh command aliases, etc. that would always get to it the fastest and most reliable way possible.

I run a local apache server, that has some virtual hosts running. Now I want to be able to locally connect to these virtual hosts, but when I try this, it puts www and .com behind the url and says it can't find it. On Windows I know the equivalent, editing the hosts file. Is there something similar in linux?

I am trying ti set up a NFS server using the guide on [URL] However, the NFS mounts on the client side as a read-only file system, so I cannot modify nothing. Here is my /etc/export file on the server side:
Code:
/home/acrocephalus/ 192.168.1.35 (rw,async,no_root_squash)
and this is my /etc/fstab file relevant line on the client side
Code:
192.168.1.33:/home/acrocephalus/ /home/acrocephalus/AcrocephalusServer/ nfs rsize=8192,wsize=8192,timeo=14,intr
Then, I mount the system using the command
Code:
sudo mount /home/acrocephalus/AcrocephalusServer/
.
how to mount the NFS with full read-write permissions?

I've been a Xubuntu/Ubuntu/Lubuntu hobby user for about 18 months now. I started using Linux as a way to revive older computers provide a backup and expand my knowledge of computing. The command line was something new to me but as long as I can find detailed directions on how to do what I want I can usually manage. I set up a Samba server for my home shared network and now I'd like to make the shared drives of that server accessible from outside my network. Via ssh or ftp or some program of the like. I'd like to have it user name and password protected. Configurable user rights would be nice. (read/write/delete/etc) As well as novice user friendly.
My end goal is a server with read/write capability that I will be able to access from work or a friends house or anywhere with an Internet connection and my laptop. I understand about port forwarding and have done so with my home network behind an AT&T U-verse router/modem. I've researched openssh and some ftp setups but they seem like they can be difficult. Now for the questions. Is this task something that can be accomplished without a degree in computer networking? Is there a program(s) that would make this a simpler task? Is this more complex than its worth? How would I go about setting up such a thing?

I share a computer with my brother. It runs Lucid Lynx. I want to add an entry to the hosts file that will affect him negatively. Is there a way I can add the entry, without it affecting him, like, is there a user-specific hosts file?

I am trying to add subdomains on ubuntu 9.10 desktop edition and and I am not sure whether I need to add some info.(such as 127.0.0.1 sub1.example.com and so on) to the /etc/hosts file like the windows' windows/system32/drivers/etc/hosts file. I used to use the wamp-server(on Windows 7), I needed to edit 3 files, httpd.conf, httpd-vhosts.conf and hosts. And almost every edit is made in the httpd-vhosts.conf file on wamp-serveriles should be edited? or what else should be done that I didn't mention?

I'm configuring Apache to work from several development directories as per these instructions: http://tuxtweaks.com/2009/07/how-to-...-apache-linux/
Got it all to work ok, for a while but then when I reboot the entries I've made in the hosts file dissapear and I can no longer use them.
I'm assuming DHCP reverts the hosts file or something?
What's the 'proper' way to get an entry into a hosts file and have it stay there?

I run a few virtual servers at home behind a NAT, including an e-mail server, with dynamically updated dns records pointing to each of the servers. Consequently, I suffer from the loopback problem when working with these servers from my desktop PC. (E.g., I ping one of the dns hostnames and the ping goes to my router instead of the server). I fixed this problem by manually adding the in-home IP addresses and name pairs to my /etc/hosts, and then setting /etc/host.conf to a "hosts, bind" order.
This seems to work for every application on my desktop except for one: the postfix installation on my desktop PC (used for mailing smartctl messages and so forth) cannot communicate with my in-home e-mail server (times out). I checked the logs, and it looks like it is trying to use the IP address from the actual A-RECORD, rather than the address in my hosts file.
So I'm not quite sure what to do. There seems to be a "proxy_interfaces" parameter in main.conf which might be relevant, but I think it only deals with received mail. I'd prefer to have the mail going to that e-mail server, rather than also having to check the spool on my local desktop accounts.

I've trying to get dnsmasq working as a combined dns and dhcp server. It's infuriating so far... In short, the DNS works fine for anything added to /etc/hosts, and the dhcp works fine, but the dhcp is not updating the dns with hostname information from clients.
The outcome of this is that i can only ping a node by hostname if i know it's address, which means setting a static dhcp allocation and putting the hostname into /etc/hosts manually, which is very annoying and kind of defeats the poit of dhcp. There must be a way to get dnsmasq to update the hosts file, surely The clients aren't using fqdn's if that matters, and i think i've tried every combinination of "expand-hosts" and "domain=" following is the dnsmasq config file contents:
domain-needed
bogus-priv
except-interface=tun0

When I converted to OpenSUSE 11.2, and went through YaST HTTP Server Configuration, creating my virtual hosts under the Hosts tab, YaST combinedm all int ile,"/etc/apache2/vhosts.d/ip-based_vhosts.conf".I did google and read, [URL]for further assistance.I'd like each virtual host to have its own file under vhosts.d, and wondering why YaST did not do that.The file /etc/apache2/httpd.conf laid out the file structure, and all vhosts.d/*.conf files are included.Is there a way to tell YaST to create separate files for each vhost, or does the user have to manually do it?

I was having a discussion with someone who asked me whether a Linux OS has to be rebooted when the hosts file is modified. From personal experience, on Windows I change the file but don't reboot and I've seen others do the same thing. I assume Linux has no exception(s), but is there any reason why a reboot is not required (to at least justify my actions)?

I am trying something a bit tricky.Suppose there is a website URL...Now suppose when i open a file /var/www/ test.php which connects to the above website to gather some info and then allow me to further in the process, i want it to instead direct to a file say /var/www/test_done.php.How do i edit my hosts file for such a scenario? Is there any other better option than using a hosts file ?

If I need to append a set (or sets) of data to a file(or files) on remote hosts what is the best mechanism by which to do that? My first thought was ssh but the command syntax to append to a remote file isn't clear to me. Can anyone point me in the right direction here?

I bought a network printer, gave it a host name, address should be assigned by my cable or DSL router. Thats what DHCP and DNS is made for right?Now I will print to that printer from my (Lucid) Kubuntu box and resolve it by it's hostname.I can't ping it by printername, I can't ping it by printername.local.It works when I login my router, read out the IP address and hostname the printer registered at the routers DHCP-table and use that address.What can be done that a router transfers the hostnames it has in it's IP-table to clients upon DHCP resolve AND whenever a client get's a new IP-Address?

What happen if we assign a static IP address to both linux and windows host?Consider host A is a ubuntu machine and host B is a windows machine. I first set a static IP for host A (W.X.Y.Z) and connect to it through ssh. Then I duplicate that IP for host B (W.X.Y.Z).The result was that I could no longer connect to the ubuntu machine!
