Ubuntu Servers :: Setup Access Properly From A Public Address To A Monitoring Server That Works Fine Locally?

Apr 19, 2011

I've spent days trying to setup access properly from a public address to a monitoring server that works fine locally. Everything works from public access until I try to link to a CVS repository. The rancid CVS repository is set up as a separate server (virtualhost). It appears the referring link causes a DNS error (105: Server Not Found) when the CVS repository server is accessed from the public address. Things work fine when accessing via localhost.

Localhost link:

[URL]

Public link: (this results in 105 error caused by redirection (bold portion of link))

[URL]

Code:

Virtualhost config:
LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so
JkWorkersFile /etc/apache2/workers.properties
JkLogFile /var/log/apache2/mod_jk.log

Networking :: QEMU: Tap Host: Windows 2003 Server - Guest: Ubuntu 9.04 - No Ip Address And Can't Access Public

Oct 28, 2010

host is windows 2003 server 64-bit
guest is ubuntu 9.04 server 64bit
Qemu : 0.11.1
Qemu manager: 7.0

from Qemu manager, if network card is using User Networking, it's a NAT and I can see that Guest Ubuntu has an ip address 10.0.2.15 and is able to access the internet. However, as Guest ubuntu is running server so I want to do use Tap networking and I assue with Tap, the Guest ubuntu will get an ip address which is in the same subnet as host machine by dhcp. so from Qemu Manager 7.0, I changed Network card to be:

NE2000PCI
Vlan Number =0
VLAN Type: Tap Networking
Mac address: tap0's mac address from host
TAP Network Adpator: Tap0

Note that tap0 was created by openvpn. and then fired Ubuntu guest, ifconfig shows no ip address on eth0 (which has the same mac address as Tap0) so the guest Ubuntu has no ip address and can't access public.

Ubuntu Servers :: Unable To SSH From Outside LAN (Public IP Address)

May 2, 2011

Basically I am trying to set up my own server so that I can ssh into it from anywhere. I am able to SSH into my server when I use the LAN IP of my server but I am not able to SSH into it if I use the public IP address. I have read many threads and in my opinion I've tried almost all of the common fixes suggested. One possibility may be that my ISP has blocked port 22. I have taken this into consideration and sent them an email and I'm presently waiting for a reply. However, I highly doubt that my ISP has restricted acess to port 22. I would really like to be able to SSH into my server from anywhere.

1). I installed openssh client/server using the following commands:
Code:
sudo apt-get install openssh-client
sudo apt-get install openssh-client

2). I forwarded port 22 on my router. (see attachment for the settings)

3). I modified /etc/ssh/sshd_config such that my server has a static LAN address.
contents of sshd_config file:
Code:
# Package generated configuration file
# See the sshd_config(5) manpage for details
# What ports, IPs and protocols we listen for
Port 22
# Use these options to restrict which interfaces/protocols sshd will bind to .....
I then entered the command:
Code:
sudo /etc/init.d/ssh restart

4). I turned off the firewall using the command:
Code:
sudo ufw disable

5). Here is the output of the IP tables:
Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Ubuntu Servers :: Setup Postfix To Relay Email It Cannot Deliver Locally?

Jul 17, 2011

I'm trying to setup postfix (or exim, I don't mind which), so I can move away my last remaining PC from Windows.I've tinkered with Postfix for good part of a month and I can get it to accept emails using SMTP and post them to a virtual mailbox based on MySQL tables. And it rejects mail addressed to local email addresses that it can't find in the table.

First question (or problem.) I've set up Postfix to relay email it cannot deliver locally such as is the case when you send out an email. My remote host requires authentication. How can I set this up?

Second question: I want to force my clients to use either AUTH, TLS or SSL, and not allow anonymous connections (to prevent an open relay server.) How do I set that up without interfering with the smarthost setting? The smarthost login is not one of my clients, it's a pre-determined login and password that is solely used for the email relaying aspect.

Ubuntu Servers :: Setup The Necessary Public/private Keys To Use In FileZilla?

Jan 26, 2010

I installed OpenSSH via tasksel and am using Webmin for administration. I'd like to be able to SSH externally and want to setup the necessary public/private keys to use in FileZilla. In Webmin, under Servers > SSH Server I can click 'Host Keys' and see an RSA key. Is this the public or private key for my server? Do I need to copy this into a text file to import it into FileZilla on my remote PC (that I want to connect from)? Is that all that needs to be done (aside from opening the port on my router/firewall)? Or, is there an automated way to set this up via Webmin?

CentOS 5 :: Unable To Gain Access To Server Locally?

Jun 30, 2009

We have a server were we no longer seem to be able to gain access, neither locally or remotely.When we try to connect via SSH we get a "Connection Refused". We have checked that it's not our standard firewall blocking the request, so it can either be the local firewall (which we disabled when installing) or that the process isn't running.However, when we try to login locally on the machine (as root) all we get is "Login failed". We've tried restarting the machine in single user mode to change the root password, and while we can do this succesfully, it still doesn't give us access when rebooting the machine afterwards.No other users (besides the standard users created when installing) are available on the server, so we can't say if this is a problem with the root account, or with logging on in general.

Server :: Postfix - One Account Cannot Send / Receive Email (Other Works Fine)

Dec 7, 2010

I just set up a new email server on Debian Lenny. It's Postfix for MTA and Dovecot for IMAPS server. I use Dovecot for authentication. I have two UNIX users on the system (except root), one was added before the installation of Postfix and Dovecot. I'm not doing any virtual things, just plain UNIX users and one domain on a dynamic IP. The first user, "webadmin" can send and receive emails just fine through the server from my mail client.

Now I just added a new user, "scarleo", and it turns out I'm unable to send and receive emails with this account. If I log in (SSH) with scarleo I can use bash mail to send emails, works fine. scarleo can also receive emails from webadmin and can connect to Dovecot to read emails. However scarleo cannot send or receive to or from anyone outside the server from my mail client. I have restarted both Postfix and Dovecot after adding the user. Do I have to do something else to make this account work like webadmin's?

A few relevant lines from mail.log: (I've modded my real IP)
Code:
Dec 7 17:44:42 homer dovecot: imap-login: Login: user=<scarleo>, method=PLAIN, rip=96.136.112.229, lip=192.168.0.18, TLS

However, I'd like to know if FreeNX can access the session that open locally on the server. I tried session 0 and 1, none of them can access the local session.

For default vnc, the connection will let you access the local session on the server. Can FreeNX do that?

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)

Ubuntu :: Use Openssl Public And Private Keys So Only A Host With The Public Key Could Access / Decrypt The Filesharing

Aug 2, 2011

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

Ubuntu Security :: SSH Server - Monitoring File Access

Oct 1, 2010

At our company we have a central server with client files. This server has a SSH server installed, and through Nautilus all employees can access the files. However, I have a few questions:

1. Most employees need access to all folders, because they might use them at some point in time. However, I want to make sure they are not accessing things they do not need. How can I do this? For instance, if somebody copies all of the folders to his/her computer, I want to be able to see this in some sort of log. Can this be done? Copying and accessing in general is what is of my concern.

2. Some employees only need access to specific folders. Can this be easily configured with SFTP?

3. Some also use SSH and type commands which I want to check every now and then (e.g. to make sure an intern is not again copying information or accessing folders they should not be in). What is a good way to do this?

Server :: Debian File Access Monitoring

Sep 16, 2010

I'm running a Debian/Samba PDC on a Windows network. We desire to monitor a few network shares, so that whenever a change is made to a file in those, we have a log of who did it and when. Some capability of seeing what the change was, or a way of reverting it, would be nice luxuries. But username and timestamp are most important, if possible.

On the debian forums, someone advised using Tripwire for this purpose. didn't give much other advice about it so I kind of struck out on my own researching tripwire. got it installed, played wth it, and found it problematic, to say the least. It seems a bit much on the complexity and security side, and it seems more oriented towards maintaining system integrity, than monitoring documents. So far I've not managed to get a policy update working on account of a cascade of errors about a few hundred files under /proc disappearing, despite no changes to the system.so I'm wondering if anyone here has advice.

1. Does debian have this sort of functionality built in? is there a system log I can parse to get this information?
2. Is tripwire the right application for our purpose?
3. Is there anything better suited, more user-friendly or more parsimonious. I don't need something to monitor all system files, guard against intrusion, and make me cups of tea, just to monitor a few folders that I specify

Ubuntu :: DNS Works Only Locally

Jan 3, 2011

I have tried to host a website at home (consider it a good option and learning experience). After using some Linux distros finally decided to stick with UBUNTU (10.10). Sadly everything was ok until the configuration of BIND9 finally failed.

I am nearly blind with most concepts of networking, my understanding is really basic and am guessing my problem is on that direction but really can not figure it out.

My set up is based on a guide found at [url] and have just changed the domain name so my configuration files are:

And for the reverse zone:

My resolv.conf file looks as follows:

With the last three lines being the IP of my ISP DNSs and declared in /etc/bind/named.conf.options as formwarders.

The output of named-checkzone arquibailleres.com is:

And:

When my BIND service is restarted its output log clearly states that the zones are added and indicates "sending notifies" yet by using dig and ping everything works nicely but when I try to connect to the site from an external computer my site simply is not recognised.

Ping output:

Dig output:

I have rented a static IP address, but still when looking for my global address I see: 201.130.192.159.

To me it looks like it is working, but I already mentioned that my understanding of that stuff is really poor, I have finally ran the "port scan tool" under System -> Administration -> Network Tools and it indicates that my port 53 is assigned to "domain" and open, also port 80 is open for www.

Ubuntu Networking :: DNS - Clients Unable To Properly Resolve The Server's Ip Address

Oct 4, 2010

I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.

I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.

What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver

I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).

If, however, I put a dot in there: ping linuxserver.

I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.

The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.

Ubuntu Servers :: Monitoring Server Stats Remotly ?

May 12, 2010

I didn't setup our old system but that server has since been retired due to hardware failure, but we have some new webervers, and a new postgtres database server in place which I need monitoring. Some items include database size, transactions per second, io stats, memory monitoring, or as the DBA put "anything I can get". We had used CACTI in the past for these items, but I didn't do the setup and sondering if that is what is recommended, or something else. I am looking at groundwork open source which include nagios, etc. but figured I would consult the uforums since all these servers are running userver 9.x and 10.x .

Networking :: Cannot Access Public Web And Mail Server From LAN Addresses

Aug 5, 2009

I have two nagging problems on one network which I do not have on another elsewhere, both using uptodate Debian servers. The server is on the private subnet behind a router/adsl modem. The symptoms of the one which does not work

1) Users cannot access their web site from lan. If they try, they get to the router web interface, same as if they entered http:10.0.0.138 which is the router's lan address.

2) Users cannot access smtp or pop3 service using the domain name, they can access it only using the servers LAN address.

I fear that I might have not set up the router properly because appart from that the two servers are almost identical but I do not know where I might have made an error.
