CentOS 5 Networking :: OpenVPN Multiple Servers With Clients Access

Dec 27, 2010

what is the best way here? I have like 5 servers, and I want my clients to access each of them, so in case 1 server is down, they can access remaining servers. Also, it will work like user1 chooses the server number and is connecting to a central database, then reply is OK, and he can connect to the server number he wished.

Jun 30, 2011

I have Unbuntu 2.32.1 Build date 14/4/11 I have Samba Installed I also have 8 Sata drives all with NTFS most of them have a lot of data on them. All my drives were used on an old windows 7 system, and now I wish to have them in a server setup.

I set up mod_proxy in order to get rid of :8080 now I cant access phpmyadmin through the browser. what is the quickest way to turn off mod_proxy and access phpmyadmin? I would like to optimize the tables and back up the sql file.

I have used a2enmod, and added

Ubuntu Servers :: Unable To Access Mysql Database?

Aug 15, 2010

We started our project (it's a website "employee performance appraisal system") in windows by starting with some html forms and then slowlyadded php ,javascript and other stuff in windows we had no issues of insertion and retrieval of data from thedatabase.Now,we decided to shift the entire stuff to drupal the html forms along with those php files but we had 2 issues with this1. the first one was ..we created "page" for each html form and copied the html code into "page" but we didn't find where our pages are getting stored (do they get stored in mysql database that we create for drupal siter do they remain as html pages somwhere?)2.second problem was ...for admin in drupal I gave the username "root" and a password ..similarly for mysql also I gave a password.

now I used phpmyadmin and created another database called "appraisal" which is supposed to hold the data of our website.when I try to insert data into one of the tables of this database (attendance table) ,the following error occured "Attempt to connect failed access denied for user 'root'@'localhost'(using password:NO) cannot run querry insert intoattendance values('x','y')" Access denied for user 'root'@'localhost' (usingpassword:NO)Also I'm unable to access mysql as a normal user only super user can access and can we unset the password that's required to reach mysqlprompt?

Ubuntu Servers :: Can't Access MySQL Remotely Via PhpMyAdmin?

Jan 3, 2011

One server is a dedicated MySQL server. After upgrading that one to Ubuntu 10.04 (from an ancient Suse 9.2), both servers are running Ubuntu 10.04 LTS.I have another server that I use to administer the database server via phpMyAdmin. However since the upgrade it is not able to connect. I get an error #1130 Cannot log in to the MySQL server. The same happens if I try to connect remotely from the command line with: mysql -u root -h 129.79.137.121 -pI'm not sure if this is an iptables/ports problem or a configuration problem on the MySQL end or something else entirely.I've searched and tried the suggestions I've found in various places but none seems to have fixed it.

Ubuntu Servers :: Cannot Access MySQL Database From Any Remote Host

Apr 15, 2011

I can not access my MySQL database from any remote host on my home network, I keep getting "Access denied for user 'dbuser'@'192.168.1.10' (using password: YES)"

From what I've read this seems to be a permission problem, I tried

'dbuser'@localhost';
'dbuser'@'%';
'dbuser'@'192.168.1.10';

and between each change of permission, I've flushed privileges.

Fedora Servers :: CUPS And LPD Clients - Cannot Add Printer?

May 12, 2009

I'm working on CUPS server here now, I am new to the whole Fedora area, I'm starting to like it, tackling one service after the other. I have cups, which I don't recall installing but was there guess its a default. So I added a printer on my server, that was on a 10.0.1.1 block, added it as lpd://10.0.1.1/lab3printer. Ok that worked and printed from my server, but my problem is when other machines try to add the printer. I continue getting this problem
Alberto "recoverable: Network host '10.0.11.25' is busy; will retry in 30 seconds..."
On the computer it was added as printer lpd://10.0.11.25/alberto because my server has that IP and printer well named it alberto. I followed what this said with the xined.d [URL].

Fedora Servers :: Samba Will Not Allow Any Clients To Connect ?

May 17, 2010

I've done this before, maybe ten times. This time is different. I don't know why, but Samba will not allow any clients to connect.

I've done:
- installed samba
- setup the samba shares
- have a samba user/passwd
- authentication = users
- punched in the samba stuff for firewall
- workgroup is set right

What the heck? I cannot get any client to connect. Not even the server machine can connect to itself through a client. What am I missing here???

Just for the record, I'm trying to connect to \SERVER:

Code:

Code:

I removed a whole lot of comment lines in the config file.

Somebody is trying to guess password and login, and making port 22 busy.What are different ways to stop this attack?I am thinking to block this ip in iptable but I have no good idea because I have not done this before. Any special consideration do I have to take while doing this thing? How is it done and which file does it modify?

Fedora Servers :: Process Of Updating All The Clients Nodes To The Same OS?

Jun 22, 2011

I'm having a problem with NFS. I'm trying to mount /home, which is on the server, to the client nodes. The server is currently running FC14 (64 bit) and I'm in the process of updating all the clients nodes to the same OS. Currently, all the client nodes are running FC8 (32 bit) and are capable of mounting /home on the server. However, the one client node that I have updated to FC14 is having problems mounting /home. I can ssh to the node with no problem however I get the following message:

Could not chdir to home directory /home/myuserid: Permission denied. Now, if I excute the following command: "sudo mount -a" I get no errors and now I can see my home directory.

Ubuntu Servers :: Setup The MYSQL Server - Error: 'Access Denied For User 'root'@'localhost' (using Password: NO)'

Mar 26, 2010

I set up a servber on my local machine, & also PHp - Both working fine.I'm trying to load up MYSQL i have installed it, & *can* start/stop the server. however if I do anything else with it, I get this error :-

Quote:

root@gordon-desktop:~# sudo mysqladmin -u root -h localhost password MYPASSWORD
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

Query :-

1) How do I know MYSQL is actually active ? (apart from the message it says that its statrted (or stopped).

2) Is there a way to

a) Find out the usernames that are recorded on the MYSQL server ?
b) set / RESET the 'root' username (I know MYSQL root user is different to PC root user)
c) anything else I can do on the PHP / website code to see if MYSQL is working

(as yet, no tables / databases etc have been set up - as I can't get past this error message - I get the same error when setting up a database.)

Ps I did allow my usermname (when logged in to ubuntu) to edit / create files in the /usr/www/ directory (but it is still OWNED by 'root' - that directory)

Fedora Networking :: Ethernet Connection Sabotaged By SELinux - AVC Denial ?

May 26, 2009

I installed Fedora to a desktop with a hardwire ethernet connection to my router. When I ran the live CD it connected fine. When I boot now I have no connection, and when I try to connect I get this "AVC Denial" message and some mumbojumbo about SELinux is preventing nm-dhcp-client to read libdbus-glib blah blah blah. The troubleshooter app is no help to me at all. This is extremely frustrating. A couple of weeks ago I did an install to this same computer and had no problem at all. The only difference is that this time I wiped all of my old distros from the HD, and made separate /, /var, /boot, /tmp, and /usr partitions (in addition to the old /home partition which I kept.) I don't know how that could be causing this problem, but it's the only thing different about this install. Should I just go back to putting everything but /home on one partition?

Fedora Servers :: Configure Evolution-mail Clients Through SQUID Proxy?

Jul 27, 2011

I have configured router(192.168.1.2) to serve only one machine with IP - '192.168.1.6' and set up SQUID proxy on '192.168.1.6'. I have defined some rules(ACL) regarding connections to internet on SQUID proxy.

I changed the Gateway of rest of machine (192.168.1.60 - 192.168.1.69) from '192.168.1.2' to '192.168.1.6'.

The policies which I defined in SQUID is working properly but 'Linux Evolution mail' client is not fetching mails.

Is I have to do any other settings on 'Linux System' or 'Evolution mail client'.

Security :: Fedora System Compromised But No Changes Made?

Jan 25, 2011

The infrastructure of the Fedora Project was compromised over the weekend and an account belonging to a Fedora contributor was taken over by an attacker. However, Fedora officials said they don't believe that the attacker was able to push any changes to the Fedora package system or make any actual changes to the infrastructure.

The attack appears to have targeted one specific user account, which had some high-value privileges. The attacker was able to compromise the account externally, and then had the ability to connect remotely to some Fedora systems. The attacker also changed the account's SSH key, Fedora officials said.

I am trying to get mysql to start at boot without any success.

The mysqld scripts works fine when run from the command line, but it does not work when i use the links created by chkconfig. I checked the boot.log and found that mysql starts but then it stops or gets shutdown. This is the log message:

Starting mysqld daemon with databases from /data/mysql [ OK ]

The same init script works fine in Ubuntu.
