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.

What is the difference between /etc/hosts and /etc/hostname?
I think the /etc/hosts file stores all ip address associated with this computer, but what about /etc/hostname?
It sounds almost like the computer name, but what is it used for?
I'm trying to change my computer name and looked up other posts and found I need to edit /ect/hostname and /ect/hosts, but neither of these folders exist so how do I change my computer name in ubuntu 10.10?
View 3 Replies View RelatedI'm facing bit of a conundrum with my new server. It is essentially a distributed-virtual Plesk Virtuoso container with a rather simple LAMP setup (PHP5 etc) and virtual hosting. Running 10.04 LTS.
The issue is that on each reboot, the /etc/hosts and /etc/hostname files are reset with their original configs causing the virtual hosting to break, i.e. rather than hosting the vhosts correctly, it essentially routes all traffic to /var/www, or essentially 000-default ~ this beats the whole point of vhosting in the first place!
Is there any way to get around them being overwritten at boot? A very crude workaround would be to set a script to load at boot via init.d and have it rewrite both files to their correct configs - of course, I have no idea as to the point during boot at which they get replaced.
I can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.
It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.
I have a network of 2 WinXP machines and one linux box. I have fiddled around with the settings as you do when learning. The network is working. The network neighbourhood on the WinXP machines recognise the linux box and vice versa, (the linux Places|Network recognises the 2 WinXP). I can Ping the linux box using its hostname from a WinXp. But I cannot do the reverse. I get an 'unknown host' response. I can ping the linux to itself using its hostname.

View 2 Replies View RelatedI have an ubuntu 10.04 server with hostname "abc.domain.com". However, due to migration, we had to change to hostname to something else, "xyz".
I have done changing /etc/hosts and /etc/hostname and run /etc/init.d/hostname start.
Checking the hostname and all shows it is now using hostsname of xyz. However, email sending out is still using old hostname. We have some scripts that will send out alerts like failed rsync or hdd space full to my email account. But I see the sender is still "root@abc.domain.com".
How do change that to xyz? I am using postfix. I have edited main.cf and restarted postfix but no go.

View 1 Replies View RelatedI'm having an issue on two Fedora Core 13 machines where I can ping others by hostname, but the hostname resolution fails whenever I use ssh/scp/vnc/etc. I can still do these things by IP address, just not by hostname. RHEL5.3 machines on the same network with the same configuration do not seem to have this problem.
Here's the not-so-quick-and-dirty description of the situation:
I know that there is a virtual router at 192.168.31.1 and another at 192.168.30.1. I also know that there is another network (let's call it 90.90.90.0) and on that network lies a number of resources. By nature of this configuration, any machine on 90.90.90.0 can be accessed by any 192.168.x.x, but not the other way around. Beyond that is out of my hands and currently out of my scope of knowledge.
I have a dnsmasq server on 90.90.90.10 that operates as a secondary nameserver, another machine out of my sphere of influence is the primary nameserver (90.90.90.31).
The secondary nameserver on 90.90.90.10 holds the hostnames of our development machines. The problem is that in some cases, while I can ping by hostname all day long, services such as ssh, scp, vncviewer, etc all fail to resolve the hostname. In other cases I can do all of these things.
Every machine has an equivalent resolv.conf:
As an example, I will show the output of a handful of my development machines:
I also included columbia as a one-way test -- even though it cannot access 30.x or 31.x, they can access it:
columbia -- physical machine, Red Hat Enterprise 5.3, IP 192.168.100.200
Okay, so here are the various outputs. Remember, nibbler, discovery, and atlantis can ALL:
- Ping by IP address
- Ping by hostname
- ssh, scp, vnc, etc by IP addess
Additionally, the SERVFAIL reply from 90.90.90.31 is expected since my dnsmasq server is on the secondary server.
Note that the only machine that can both ping and ssh/scp/etc by hostname is nibbler, which also happens to be the only one of the three running RHEL5.3 instead of FC13. Other virtual and physical machines running on the 192.168.31.0 and 192.168.30.0 networks (all running RHEL5.3) work just like nibbler does. So the problem seems to only affect machines running FC13.
Final note: selinux is disabled, iptables is disabled, ip6tables is disabled.
Other than that, discovery is a brand-spanking-new install straight off of the FC13 DVD. atlantis has been around longer, but its just a file server so I haven't done anything too crazy to it.
How do I set $HOSTNAME to dynamically update with the hostname that is specified for the ip in DNS?

i have a computer with 3 users on it, and a folder using samba that everyone on the network has access to. Lets say that, the folder is stored in /etc/sharedfolder. What happens is, when user1 puts a folder in it, then logs off, user 2 attempts to modify it and fails, because permission is set to 755, and they are not in the same group. (even if they were, it should still need to be 775) Anyway, my current solution is, every 5 minutes a crontab changes permission like so: chmod 777 -R /etc/sharedfiles && chown useradmin:superadmin -R /etc/sharedfiles Which works, but seeing as there is getting close to a gig in there, this is a bad solution, as it eats up the computers resources. Solutions that i think might work:
1) create a script that only changes permissions that need be changed.
2) change file permission settings to force all documents to inherit parent document settings

When creating their account, I have turned off the 'Connect to ethernet and wireless' option of the Advanced Settings.
However, when I log into their accounts, they still have full access to the internet through both the wireless and ethernet connections. Is this option for some other purpose?

I'm have been tasked with created a base Ubuntu image that can be used for cloning to multiple machines. As this is a network environment, each hostname will obviously need to be unique. Rather than manually changing the hostname each time a new, cloned machine is rolled out, I was wondering if there is a way to use a variable in the hostname (i.e., use a variable to truncate the the last 6 digits of the MAC address to the end of the static hostname--or any other unique variable for that matter--so it would look like hostname00E6D4).
