[SOLVED] globbing in /etc/hosts or something similar

Is there any way to glob addresses in /etc/hosts?
If not, which seems to be the case, is there something else that could achieve a similar effect?
Example:
127.0.0.1 *.localhost # enable subdomains on localhost (with Apache virtual hosts)
It's not that tedious to manually add them and I could probably write a script, but it would be useful for other things (127.0.0.1 *.google.* )

BIND supports DNS wildcards, which seems to be what you're after.
Just for fun I went through the process of setting this up, and it's not too difficult. I did need to do a bit of research to figure out the syntax for the DNS zones. Fortunately, there are plenty of resources which describe this.
Briefly, the process I went through for wildcard domain resolution:
1) Install bind and invoke named
2) Ensure the nameserver is included in resolv.conf and that the DNS service is in the host DB of /etc/nsswitch.conf
3) Edit /etc/named.conf and the corresponding zone file.
There's an article on debian-administration which focuses on exactly the case you proposed.

Is there a similar file to windows\ssytem32\drivers\etc\hosts in OS X

Hi,
I am running a Windows 2003 Server with several websites. I would like to view my websites from my new Imac, however I keep getting prompted for the user name and password for the router.
In windows on my old computer I could edit the file C:\Windows\System32\Drivers\etc\hosts with the IP address and URL of the site and it would open. Is there a similar file in the Mac OS X 10.5.7 software.
Many Thanks in anticipation

Adding host records by editing the /etc/hosts file is not entirely reliably. Since Leopard, some people have reported issues of the added host records "mysteriously" disappearing, or Apache not being able to properly resolve the added hosts. The bigger issue is that the modifications in the /etc/hosts file can create unwanted side effects in the normal functioning of services like the mail server and others.
Since Leopard, there has been an alternate way to add host records using the dscl utility. In fact, by many, it is considered the better, more reliable, and safer method.
You can read this recent article to see how its done:
http://tomafro.net/2009/07/dscl-the-easy-way-to-add-hosts-on-osx
There are a number of additional articles on the web about using dscl for adding host records to OS X.
The choice, of course, is yours. If you are using the /etc/hosts file without issue, then it might be safe to continue doing so. But, if your system starts experiencing domain name resolution issues or problems with services such as the mail server, you should consider switching to and using the dslocal database to manage your host records.

Something similar to /etc/profile in LDAP?

My /etc/profile contains a logging feature which tracks the history of a local user. It doesn't work for ldap users though since I don't think LDAP looks at this file when ldap users login to a client.
Is there some way to make ldap users use this file as the initial login profile or is there some way to setup something similar in LDAP? ldapaddent won't add this file. The only thing I can think of is to make some sort of change on cn=default,ou=profile,dc=example,dc=com but I'm unsure as to whether that will work or how exactly to set it up.
Any help on this would be appreciated. Thanks.

Hi Liam. Thanks for your reply. When I used the Update Credit Card option and tested the form, I got the error message "Credit Card Payment Failed….Invoice Number Not Found". But after search for that error message in this forum, I found out that I should be using the "Credit Cards (existing orders)" option. This has worked, ie payment was successfully processed and was applied to the existing order; a new invoice was not created. I have received a receipt from the payment gateway (eWay) but not one from BC. Also, upon successfully submitting the form, I was then taken to a totally blank page. I'll have to do some more testing to see whether the blank page was just a one off. If not, I'll try adding code in the Action part of the form to redirect to specific page.
So thanks for your help. Though it didn't give me the correct answer, it l led me to it.

[SOLVED] Strange line in /etc/hosts

I was checking my /etc/hosts when I came across this line:
64.50.236.214 releases.mozilla.org
Should that line be there? Is it safe?
That ip points to a mirror site.

No, I didn't. That's why I was so worried.
Edit: I can download plugins with Firefox even without that line. I found out that my brother had used an arch live cd to change /etc/hosts because he couldn't download plugins, the problem mcmillan mentioned.
Thank you guys for quick answers.

[SOLVED] Is there something similar to FinePrint for Linux?

Hi,
when I was still using Windows, I used a freeware similar to FinePrint (don't remember the name) and it was very useful. So far this is the only application I miss. Is there something similar to that available for Linux?

Stuff means anything that can be printed, so it is not about creating pdf's or something similar. Just to watch and edit what you want to print before you actually print it to paper, and that independent of the program you are using.

Setting up /etc/hosts (SOLVED)

How can I do that. Every time I launch Xfce4 I get a message about adding my name to the file. I add it like:
213.112.235.47 wilma.bredbandsbolaget.se wilma
And the message disappears but some programs dont work. Any suggestions?

Just put the hostname you use in etc/rc.conf at the end of the line with localhost in /etc/hosts and you'll be fine.
The code below shows the way i have set it up.
networking part of etc/rc.conf
# NETWORKING
HOSTNAME="julius"
/etc/hosts
# /etc/hosts: static lookup table for host names
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost julius

Ntrights.exe Windows 2008 R2 Resource Kit Tool? Does it exist or is there something similar I can use?

I am running Windows Server 2008 R2 Standard as a DC
I am trying to add users/groups to the following local policies through a GPO, however I need to script it out using something similar to ntrights.exe. I do not want to do it through the GUI because this is going to be a re-occurring process.
Below are the policies I am trying to configure via some kind of command prompt. I do not think I can do this with PowerShell 2.0 even with the import-module grouppolicy cmdlets.
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Allow log on locally
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Debug programs
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Force shutdown from a remote system
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Shut down the system
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Change the system time
Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Allow logon through Remote Desktop Services
Would it be safe to copy the Windows Server 2003 ntrights.exe resource kit tool and try it on Windows Server 2008 R2? I am working on a virtual test lab environment so I can actually take a snapshot before hand but wanted your expert thoughts on it first.
Thank you in advance.

I found the solution.....You can actually use "quoted" host names in the templates instead of the SIDs. Make sure that for Domain User Accounts you specify the Domain prefix. For Local User accounts you can just specify the local user name.
The filename of the template that I made is LOCAL_SEC_TEMPLATE.inf
Here's what's inside that LOCAL_SEC_TEMPLATE.inf template:
[Unicode]
Unicode=yes
[Registry Values]
[Privilege Rights]
SeInteractiveLogonRight = "Administrators","XXDIGIHD\DigiOps","XXDIGIHD\Domain Admins"

Editing etc\hosts file on windows xp for apps. problem post installation.

Hi all,
I was able to install 11.5.10.2 apps on my win xp prof machine. During that process I had to edit the etc/hosts file in windows directory as a work around for that domain name field during installation. Also added the primary DNS suffix as 'suneel.com' . I gave the domain name as 'suneel.com' during installation. The RapidWiz is taking localhost as the system name and referring to this system as localhost.suneel.com, though the actual system name is 'websoft-xp' .
The host file on Apps machine has the following entries:
127.0.0.1 localhost
127.0.0.1 localhost.suneel.com suneel.com
127.0.0.1 websoft-xp.suneel.com
So when I connect to apps login server from other systems in lan, I've to edit their hosts file and add an entry for localhost.suneel.com to point to its ip address or else the apps throws an error after logging in as operations/welcome using a different url say 192.168.1.4:8000 . Is there a way to get around this issue?
More over I'm not able connect to VIS db from other systems. The oracle clients give an error 'No listner' at this address. (The original listener was listening at localhost.suneel.com:1521). So I tried to create a new listerner from Net Manager that actually listens at websoft-xp (the real system name) but it throws me an error 'A valid log file is required' while saving the network configuration and prevents me from saving the network configuration.
Did I do something wrong with the hosts file during installation or did i miss any entries in that file thats causing this? Any solutions for the above problems will be appreciated?
Thanks

Well I tried that option but for some reason it didn't work for me. It kept giving the tns:connection closed error. Then I searched in metalink and found this note : Note:333158.1
It suggested setting tcp.validnode_checking = no
in sqlnet.ora. in

And it works. Hope this helps someone facing a similar problem. Good luck.
BTW how do I run autoconfig?

/etc/hosts for dhcp

Proper /etc/hosts for my situation

Hello all,
I just (finally) got set up through an ISP which assigns me (well the DSL modem) a publicly routable dynamic address. Anyway, I've setup a dyndns.org hostname, and ddclient to update it, and it routes beautifully to my linux box, through the dsl modem which has the ssh port (and other services as they come up) forwarded to the proper box.
Anyway, I was updating my /etc/hosts, and I'm wondering if I have it setup correctly.
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 XXXXXXXX.homelinux.org localhost.localdomain localhost XXXXXXXX
192.168.0.51 XXXXXXXX.homelinux.org XXXXXXXX
192.168.0.50 regulator-pc regulator-pc.localdomain
192.168.0.1 qwest-modem qwest-modem.localdomain
192.168.0.2 regulator-bridge regulator-bridge.localdomain
# End of file
Please replace all instances of XXXXXXXX with my actual hostname.
This box (XXXXXXXX) has a static IP of 192.168.0.51, is that line correct?
I've left the (hostname.localdoman) stuff in my hosts lists since at one point I had a caching bind server running on my local net, but I've yet to set that up on this network.
regulator-bridge is my dd-wrt'd wrt54g, which now is set up in client bridge mode to allow the boxes with ethernet ports to join the network (routed off the DSL modem), and so I don't have to run an ethernet cable across the living room to the DSL modem. Works like a champ.
Appreciate any input.
Thanks.

Network-profiles (1) and /etc/hosts

Hi everyone,
i've got a few network-profiles, especially in one network I have to use a static ip to connect to the internet. The only entry in the /etc/hosts which works correctly - without any error messages - for me, is
192.168.0.99 localhost.localdomain myhost
If I use something like 127.0.0.1 in front and simply add my hostname at the end, I can't connect with the Inet, unfortunately. I did not test it, but I'm pretty sure, that this host configuration won't work in any other network, where I get a dynamic IP from the DHCP. Is there a possibility to write the content of the /etc/hosts with netcfg, like the /etc/resolv.conf for example?
MfG Skit

Because you didn't specify what localhost was in your hosts file. It only knows of localhost.localdomain(does not imply 'localhost') and acer being the loopback.
I think he understood that.
'localhost' is universally understood as the loopback.
this is some kind of 'magic' answer isn't it? the resolving doesn't come out as a miracle... and that is IMHO what needs explanation.
his computer alone doesn't (obviously) get it because sure, it's not set. now what 'magic' makes it known when a cable is plugged in? the computer tries to reslove locally (via /etc/hosts), fails at it, and then asks the dns server about it. so I reckon the dns server is instructed on replying '127.0.0.1' for a 'localhost' hostname request. why so? because dns servers have an option to look at their local /etc/host for resolving before delegating to bigger servers, so the dns server certainly has localhost matching 127.0.0.1 in his /etc/host, and blindly replies accordingly, oblivious to the fact that he is replying about his 'own' 127.0.0.1 to someone else.

/etc/hosts

I guess this belongs here, if not, mods, I apologize :)
I set up a Centos server and was browsing logfiles and noticed that instead of the usual 'localhost' string that I see in my Arch logs it had my hostname in all of the log files. After a little digging I found this on the Debian forum. I've edited my /etc/hosts how the post describes and lo and behold, after restarting syslog-ng, I get my pretty hostname in my logs. My question is, this runs contrary to how the Beginners Guide directs to set up that file and contrary to how the Arch installer sets up /etc/hosts. Did I just mess something up or is this an oversight? I didn't want to go editing wiki pages not knowing for sure. It seems like everything is running just fine on my machine now.
For reference, here is how my /etc/hosts was:
127.0.0.1 localhost.localdomain localhost archdesk
This is how it is now
127.0.0.1 archdesk localhost
Thanks.

The hosts file has three parts on each line. First is the ip, second the canonical (full) hostname and the third part is an optional list of aliases. In your old situation this means that the first alias (which was used for the logfile) was localhost.
With either:
127.0.0.1 localhost.localdomain archdesk localhost
or:
127.0.0.1 archdesk.localdomain archdesk localhost
I would expect you get the desired behaviour (not 100% sure though).
Read

Sshd ignores /etc/hosts.allow and /etc/hosts.deny

Hello everyone,
I've just found out that sshd ignores /etc/hosts.allow and /etc/hosts.deny completely on my machine. It doesn't make use of tcp_wrappers. I am using the standard Arch package. Either my settings are wrong, or this is a severe security problem. It was a terrible surprise to find out that my server is under severe dictionary attacks all the time, despite the denyhosts script I am using.
These are my settings:
/etc/hosts.deny:
ALL: ALL
/etc/hosts.allow:
# some nfs daemons: 192.168.1.0/255.255.255.0
sshd sshd1 sshd2: ALL EXCEPT /etc/hosts.evil
mysqld: 192.168.1.0/255.255.255.0
/etc/hosts.evil:
195.113.21.131
60.10.6.53
A simple experiment to verify the settings:
[root@charon etc]# tcpdmatch -d -i /etc/xinetd.conf sshd 195.113.21.131
warning: sshd: no such process name in /etc/xinetd.conf
client: address 195.113.21.131
server: process sshd
matched: hosts.deny line 5
access: denied
[root@charon etc]# tcpdmatch -d -i /etc/xinetd.conf sshd 195.113.21.130
warning: sshd: no such process name in /etc/xinetd.conf
client: address 195.113.21.130
server: process sshd
matched: hosts.allow line 10
access: granted
This seems to be fine. But when I go to the machine 195.113.21.131, I can simply log in with no trouble at all.
This is really strange. Does it have something to do with the xinetd warning? I am not using xinetd... Maybe I'm doing something wrong. If you have experienced such a trouble, please give me a hint.

My guess would be that since it listens on all local addresses by default, we're just overwriting that when specifying 0.0.0.0, which isn't valid. That was users don't have to specify their local IP address. Unless I'm wrong, shouldn't this be a bug/feature request for the packager?
This doesn't seem to be a package bug... IMHO, sshd must respect all the settings in hosts.deny and hosts.allow, regardless the IP address it listens on. The behaviour I noticed seems to be much more complicated. Basic settings (daemon name mentioned in hosts.*) worked, as far as I didn't want a "per IP" configuration. For example, including the daemon in hosts.allow really enabled remote connections, but any closer specifications (subdomains, EXCEPT operator...) were ignored. Access was simply granted without further evaluation. Excluding sshd from hosts.allow worked as one would assume. When I specified ListenAddress, everything started to work properly. This is mysterious. There are millions of computers using tcp wrappers and ssh, so it's hard to believe there could be a bug.

How to save etc/hosts

Hi all,
Please help sorting my terminal, I'm having problem with my iTune everytime I want to update or restore my ipad or iphone, it keep saying "this device isn't eligible for the requested build"
Now I tried to edit the etc/hosts using the Terminal, but suddenly all the script
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1          localhost
255.255.255.255          broadcasthost
::1             localhost
fe80::1%lo0          localhost
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com
are all gone i think i accidentally deleted it. so what I did was I copy this from forum and paste it to terminal.
But i'm having problem how to save it, when I press ^O it goes like this:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1          localhost
255.255.255.255          broadcasthost
::1             localhost
fe80::1%lo0          localhost
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com
File Name to Write: etc/hosts
^G Get Help         ^T To Files         M-M Mac Format      M-P Prepend
^C Cancel           M-D DOS Format      M-A Append          M-B Backup File
and I dont know how to save it. when I press ^X doesn't save at all.
Please Help me.
Thank you in advance.

Well lets make things easier, get out of Terminal by just Quiting it or Force Quit.
Download the free TextWrangler here
http://www.barebones.com/products/textwrangler/download.html
Now under the File Menu >Open File by Name
/etc/hosts
It should look like this, if not then just copy and paste it in.
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
fe80::1%lo0     localhost
Now save it and give it your admin password and that's it. Easy as pie.
Terminal's pico and vi editing programs have a lot to be desired, but serve the basic puposes.
With Terminal you need to enter
sudo pico /etc/hosts
then enter your admin password to access a system file.
It can only be done via a Admin account, however with TextWrangler not only is it much easier, you can also access system files from a Standard user account.
the two lines
#74.208.10.249 gs.apple.com
#127.0.0.1 gs.apple.com
You have there are "commented out" with the "#" symbol, basically your telling the computer to "ignore this line"
Why you think messing with your /etc/hosts file is going to solve your primary issue with iTunes/iPad/iPhone is beyond me.
Did you ever think that perhaps your two devices are too old for the "requested build"?

[SOLVED] globbing in /etc/hosts or something similar
