Fedora Security :: The DNS Server Discloses The Remote Host Name - Can This Be Turned Off

Jun 15, 2010

We recently had a vulnerability scan done on our network and one of the vulnerabilities was that the dns server discloses the remote host name when using hostname.bind.

Is there any way that we can stop this from happening? Our name server is a Fedora 11 machine.

Ubuntu Networking :: Wireless Switch Can't Be Turned On Again After Being Turned Off

Feb 2, 2010

The wireless connection works fine. The wireless switch automatically turns itself on every time I start the computer. However, after turning it off, I can't ever turn it on again unless I restart the computer. And because of this, the wireless connection is disabled until the next time I start the computer.I don't think this is a hardware problem because the switch can be turned on and off, although not in the way I expect.

I'm using ubuntu 9.10 on an Acer Aspire 4740G. The command [lspci | grep Network] shows Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01). the [rfkill list] command shows (when the switch is on)

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

and, as expected, shows (when the switch is turned off)

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

I just want to be able to turn the switch on or off at any time I want as long as the computer is still on.

Server :: Copy/delete Files On Remote Server?

Jul 6, 2010

Allright, I made a simple script that tarballs my SQL databases weekly and saves them to a backup harddrive.If possible, I would like to have the backups uploaded to a remote server for storage. But, I must have the script delete the previous upload for size contraints.I can only use rsync, scp or sftp. Haven't used any of them really before... Here's my basic tarball-backup script:

Code:
#/bin/sh
# Dates the new tarballs of current builds.
DATE=`date +%m_%d_%Y`

CentOS 5 :: Passwordless Ssh Login From Windows - Uploaded The Generated File Id_rsa.pub To Server

Aug 22, 2009

I have an rsync server and am now setting up cwrsync on my windows machine. I want to be able to run cwrsync over ssh with public private keys. I followed a tutorial over here to set this up. It, however, still prompts me for server password and works only if I provide the password. For some reason the public/private key process is not working.

- I generated a key using the command: ssh-keygen -t rsa -N '' (I verified the key gets generated on my Windows machine)

- I uploaded the generated file id_rsa.pub to server /root/.ssh/authorized_keys

I am also prompted for a password if from command prompt I run this command to log into server: ssh -i c:docume~1user.sshid_rsa root@<server_ip_address> On server I have changed the configuration file (/etc/ssh/ssh_config) to say:

RSAAuthentication yes
PubkeyAuthentication yes

I then restarted the sshd service, however, to no avail.

Networking :: Turned On Query Logging On Our Name Server And Immediately Saw Repeated Queries For?

I recently turned on query logging on our name server and immediately saw repeated queries for . (dot). I've not seen this before. It looks like a really sloppy DOS. What would this return if my NS was misconfigured?

OpenSUSE :: Add / Setting -auth -audit In X Server

I'm trying to add the -audit option to X Server. I run ps -ef | grep -v grep | grep "bin/X" and get: root 2511 2506 0 10:35 tty7 00:00:09 /usr/bin/X:0 -br -verbose -auth /var/run/dgm/auth-for-gdm-sScn1P/database -nolisten tcp vt7 So I'm thinking that I need to add -audit to the /usr/bin/X file, but I believe that it's binary and created by something else, but I can't find that "something else". How on earth can I add this option? I have opened up 1,000,000,000,000,000,000,000 files (slight exaggeration) and I've come up empty.

Server :: Sendmail SMTP AUTH Errors?

Aug 3, 2011

I am a bit of a linux newbie, but have been gradually teaching myself how to set up Sendmail 8.13.8 on a CentOS system to handle our MX mail for various domains we own on our local server. Configuration has gone well so far, except I cannot seem to get Outlook to authenticate with the SMTP server and I must readily admit to some large gaps in my knowledge. For testing purposes, I have tried to authenticate using Telnet with the following results:

Code:
220 my.domain.com ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Aug 2011 14:27:00 GMT

Security :: Convert One's Private Key To Id_rsa?

Apr 17, 2011

Some people have said that it's dumb to use the same key for multiple things, but for curiosity's sake, is it possible to convert one's private key to id_rsa? I know that I can convert my public key to id_rsa.pub with ``$ gpgkey2ssh [key ID] >id_rsa.pub'', and that makes me think that there should be a way to do it with my private key.

Server :: Vsftpd With SSL Auth But Force Plain Data?

Aug 26, 2010

I'd like to enable SSL authentication in vsftpd.conf but still somehow force plain data transfer; even if the client is capable of SSL data transfer. The way I understand the config, if I set ssl_enable=YES then if client wants to use SSL for data transfers, it can. I wish for force plain data transer, but still have SSL enabled for login. Is this possible with vsftpd?

General :: SMTP AUTH, Sendmail Client To Postfix Server?

Dec 2, 2010

I'm hoping someone here can help, as I've been beating my head on the wall for a week now with little advancement. I've found a number of tutorials on setting this up, however none of them have gotten me 100% of the way there. Here's my situation: home-based Fedora server (Core 8), running sendmail 8.14.2-1. Connecting to hosting company's smtp server over port 587, to bypass Verizon's blocking of port 25.

My /etc/mail/sendmail.mc file looks like this (comment lines removed):Quote:

divert(-1)dnl
define(`SMART_HOST', `smtp2.datarealm.com')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 PLAIN')dnl

Server :: Sendmail To Verify Sender Enveloppe Even Though SMTP AUTH?

Aug 1, 2010

I got one last stop until I've fully configured my Sendmail server. I want the server to verify which address the sender is using when sending mail. Even though authenticated via SMTP AUTH or mailing from an IP listed as RELAY in access.db, the user should not be able to use whichever address he likes.

Ideally, I would like Sendmail to use a file that looks something like this: Username sername@Server.org

where, if logged in with Username, the only accepted sender address is Username@Server.org. As of now, Sendmail just verifies that the sender domain exists and then relays which I don't like. This also applies to a lot of other servers as well... for example in the cases where ISPs have blocked outgoing port 25 and let all their users use their SMTP server. I assume, if they don't use SMTP AUTH which is not the case where I am, that they have their entire IP range listed as RELAY and therefore, using my ISPs SMTP when in their net, I can send mail as whomever I like as long as the sender domain exists.

I've had a look at filters but haven't found any suitable and I assume that this might be realised through a Ruleset or something. What do you think? Have I missed something making this a really stupid suggestion or am I on to something? It would make my day

Ubuntu :: Remote Copy Like Scp But Without Encypt

Jul 16, 2010

I really like scp for sending a random file here or there, were a permanent share is overkill. Sometimes I send a very large file over a local network that has no reason to encrypted. The encryption maxes out the processor that needs cycles for other stuff and bottlenecks the transfer. Is there a command with similar syntax without encryption?

Server :: Monitor The Current Bandwidth In Use By A User (NCSA Auth) On Squid?

Jan 29, 2010

Is there anyway to monitor the current bandwidth in use by a user (NCSA auth) on squid? Occasionally we get a user downloading too many videos at once, which blocks bandwidth to other users on the network. As I have no idea which user it is until the end of the day (SARG reports), we just restart the squid server to disconnect their downloads.

Ubuntu Networking :: Remote Web Server Access?

Sep 7, 2010

I have installed Ubuntu Server (lamp+openssh) on a laptop in order to use it as a testing web server for my projects. After configuring it I've also installed the GUI to make things easier as I'm not very proficient using just the command line.

I'm using the wireless connection on the laptop to communicate with the router and my main desktop (Windows). I've assigned it a static local IP (192.168.1.99) in order to be able to access the sites on my web server from my desktop, and everything works fine.

Now comes my problem: I need to be able to access those local sites from a remote location (outside of my local network) as well. How can I do that?

Ubuntu :: Regularly Need To Copy Files From A Remote Computer?

Mar 11, 2010

I regularly need to copy files from a remote computer to wherever I am working. I've ben looking into alias and the .bashrc (or .profile in the remote computer - mac) Can I use scp in these files? I've tried:

Code:
alias='sch usr@location:'
then when in the local terminal:

Code:
sch path/file .
But this doesn't work.

Better would be copying when logged into the remote location, but I haven't figured that out in terminal yet, let alone an alias for it. Hopefully it'll be a quick solution!
