Ubuntu :: External USB HDD On 8.10 Server

Server :: External SMTP Server With PHP / Send An Email Using An External Server?

Feb 9, 2011

I'm rather (VERY) inexperienced when it comes to Linux, but Fedora 14 is the environment I have to use on my laptop at work, so please forgive any dumb that comes out of me.

How do I tell php to send an email with mail() using an external mail server?

The situation: I've got apache/php running a webserver on my local machine. It's for dev purposes only, and the website files I'm using are checked out from our SVN. This lets me make changes to our website while not actually changing our website.

I've come across an issue I'm fixing where I need to verify that an email is successfully getting sent out, and unfortunately, this email is sent out using php's mail(), and not our website's usual $mail object. Unfortunately, I don't have the authority to change how this sends out right now, just when it sends out.

I've been running everything fine on my machine for a month now, and haven't needed the mail stuff until now. How do I tell php to send an email using an external server?

Server :: Configure Internal Zimbra Server To Use External Server To Send Mails?

Feb 16, 2010

I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?

Server :: PHP And Sendmail With External Mail Server / Failed Reverse DNS Check?

Jun 7, 2010

After searching the forum I could not find a clear answer to my question so I am giving it a try...

I have installed a LAMP server with Postfix as mail server. The scripts send email as user www-data using the mail server on the same machine.

However, the email got rejected by external mail servers (failed reverse DNS check) so I setup a mail server that meets all needed requirements.

Now I would like to use this second server instead of the mail server on the LAMP server. I found that this could be done with changing sendmail settings in php.ini (I think).

However I am not sure how that will go: www-data is no actual user on the new email server (which requires authentication before sending). Do I need to create a new user on the email server or change the settings in php.ini to match an existing user?

Debian Configuration :: DHCP Server With External Dns Name Server

Jun 14, 2011

I wanted to setup my server as a router/gateway just for educational purposes and also when it succeeded i will keep the gateway and place it on the front line right after my modem.

My current setup as it is now :

The GATEWAY/ROUTER will be doing the main work to act as a dhcp server and firewall.

Now my setup as it is now :

So now what i ment to do was :

Let the clients connect to the gateway via ETH1 and all the stuff being router to ETH0 which is the NIC that is connected to the internet.

But now i have two huge problems :

1. The DHCP configuration seems to be fine the client machines get their ip adresses and /etc/resolve.conf looks fine to. But somehow the GATEWAY/ROUTER wont let me use the specified external DNs server so i cant do anything on these machines.

2. The firewall script [url] at line 27 should be DROP but if i use this line of code the GATEWAY/ROUTER cannot use his dns server settings so when i try to browse the internet or ping a machine outside my local network it would came up with nothing.

Server :: Configuring Postfix With External SMTP Server?

Apr 10, 2010

I'm trying to configure Postfix with a mail server that I programmed in C. The main.cf is set in this way :

Code:
relayhost = [myMailServer.localhost]
smtp_sasl_auth_enable = no
smtp_use_tls = no
disable_dns_lookups=yes
smtp_never_send_ehlo = yes
code....

I don't know why it doesn't receive response after HELO. In fact if I debug my mail server with gdb, I can see it sends a 250 response code. Moreover, I've tested my server both with traditional mail clients, as Thunderbird, and through telnet session and it works very well.

Ubuntu Networking :: VPN With Authentication To External Radius Server?

Jun 25, 2010

this is all I need simple VPN with authentication to external Radius server. Here is what I have done to try and get this goal accomplished. 1st try using PPTPD and Radius plugin No matter what I have tried (long explanation here [URL].. I can't get PPTPD to talk to my Radius server, even though I can authenticate using the same server and radius server using pam radius. PPTPD just won't, and so far the POTOP mail list has been quiet since my post to them and no replies/ideas in my other post, see forum link above.

2nd try using OpenVPN and their pam auth plugin. I give up on this one! I have the server working great BUT! As soon as I enable the plugin /usr/lib/openvpn/openvpn-auth-pam.so in the config I get this when trying to start the VPN server. kernel: [3725586.167177] openvpn[28364]: segfault at 0 ip 00007fd6e5e38fb4 sp 00007fff434f18f0 error 4 in openvpn-auth-pam.so[7fd6e5e38000+3000] Google turns up nothing on Segfaults on the openvpn-auth-pam.so Ug at my wits end, anybody have any other suggestions? I'm at a total loss ATM.

Ubuntu Servers :: Backing Up A Server To An External Drive?

Jul 17, 2010

I have an Ubuntu server running Lucid. I'd like to be able to back up the hard drive in the server to an external hard drive. I try to plug in a drive via a USB port and it doesn't appear to mount automatically, as it does on the desktop version. Questions: 1) What/where should I be looking for to see if the drive is mounted? (I've looked in /dev and /media; no dice.) 2) What's the mount command I should use to manually mount the external hard drive? 3) What backup commands or programs, other than rsync, are recommended? (Nothing against rsync.)

Ubuntu Servers :: Apache Server Not Accesible From External Computers

Dec 8, 2010

A week ago I purchased an VPS. The first few days I was having trouble to set up an outgoing connection on the VPS. Eventually it turned out to be some misconfiguration of the server where the VPS is hosted on.Since then I have installed the apache server, but I'm still not able to access the apache server from an external computer. I already have contacted the provider, but they haven't replied yet. To speed things up I was hoping someone could check my configuration to be sure nothing is wrong with it.To be sure I posted all configuration and information that I think would be important. Please contact me if you need more information.

Server :: Active Directory Roaming Profiles On Ubuntu External HDD?

Nov 4, 2009

I have a Ubuntu 9.10 desktop, with an external HD shared via Samba, with some users and folders on it. I have another computer on the network running Winblows Server 03', handling Active Directory (that I am still setting up and testing before any serious implementation.) I've been testing GPOs I am building on an XP SP3 virtual machine that is running off my Ubuntu desktop as well, that I joined to the AD domain.

However, the Domain Controller doesn't have a very big hard drive, and I'd like to take advantage of having 930GB free on this external hard drive for roaming user profiles, especially since I backup all of the drive contents every week. This would simplify a lot for me. What would you recommend is the best way to go about setting this up with my Samba configuration? I have a feeling /media/Slave/UserProfiles permissions will get somewhat complex.

Server :: Apache - Cannot Hit Site External

Aug 24, 2010

Only from internal lan. I have secondary IP address added for SSL site, and we are natting that address from that outside. I can hit it if I change my hosts file to that local IP on the server itself, but when using external NAT address it never hits the server. But if you telnet to that external address with port 80 or 443 it works.

Here is a sample of my config with servername and ip addresses changed:

<VirtualHost 192.168.150.100:80>
ServerName sample.website.com
ServerAlias sample.website.com

Server :: External Machines Can See SOME Subdomains But Not All?

Sep 16, 2010

I have a DNS server on my LAN at 192.168.140.25. Going by the example in the O'Reilly DNS and BIND book I bought, I set up the domain movie.edu and [URL]. To my great surprise and delight, I can access toystory.movie.edu in a browser from another PC on the LAN (as long as I add 192.168.140.25 to the DNS servers). Encouraged by this victory, I decided to try to set up another subdomain at [URL].

This kind of worked but not completely. Interestingly, I can get to both [URL] and [URL] on my server, but on my PC, I can only get to [URL] not [URL]. Here is my db.movie.edu:

Code:

$TTL 3h
movie.edu. IN SOA toystory.movie.edu. al.movie.edu. (
1 ; Serial
3h ; Refresh after 3 hours

Server :: Using An Email From An External Domain?

Mar 20, 2011

I have a slackware machine which has preinstalled the sendmail mail server. For this machine I have given a domain name (I have a static IP), so I'm able to administer my email through the UI of webmin, i.e. I can send and receive emails.

However I would like to use it only as an email server, i.e. what I would like to do is Conecting to it, by using an email client (e.g. Thundirbird) in order to receive and send emails Conecting to it from a web server so a to send new posts etc.

By searching around I found that in order to test the mail server from outside you can use the following series of commands:

Code:
telnet mydomain 25
helo mydomain
mail from:<useremail_in_my_domain>
rcpt to:<useremail_in_external_domain>
...

However in rcpt to: I receive an error "Relaying denied".

Here is also the DNS configuration

Code:
NameModeValuePriority
domainnameAmyip0
*.domainnameAmyip0
mail.domainnameMXmyip1

how I could configure the email server?

Ubuntu :: Set NTP To Point To An External Server, But My Thin Clients Don't Get That Setting For Some Reason?

Apr 8, 2011

I'm running several Ubuntu servers with LTSP thin clients in our classrooms. It's been a royal pain trying to get them to synchronize time properly.Currently I'm looking at 7 client's login screen and each one has different time. It's frustrating and I've done all the reading I could in regard to NTP and LTSP with time, etc.I'm trying to even set NTP to point to an external server, but my thin clients don't get that setting for some reason. They still pick whatever time they want to present to the end user. Once the user logs in, the time seems to be fine. It's just at the login screen.Since I'm no expert on NTP I figured I'd ask to see what users here thought.

EDIT - I was told that the GUI version of Ubuntu handles NTP at System-Administration-TimeAndDate. Is this true? I was told my /etc/ntp.conf file is empty because that file is only used in the server edition of Ubuntu.

Ubuntu Networking :: Can't View External IP Links To Http Server On Same Machine

Sep 1, 2011

I have an apache server running on my ubuntu machine. I can view them using my local ip (192.168.1.6):80/. And my friends can view the things hosted on my server using my external ip (example http://123.123.123.123:80) but when a friend links back to me to show me what they are looking at and share the moment, I can't view the link, it simply redirects to my router login page.

I had an older linksys router and this could work fine. I could click on the links with my external IP and it routes back to my server for viewing.

Remember to note that I am on the machine that has the server, and I'd like to be redirected out and back to it so we can share pictures back and fourth without me having to replace the external IP address with my local one just to view that link in the browser.

Server :: Ftp: Vsftpd With Firewall - External Ip Is Blocked Out With X

Jan 3, 2010

i have a server running vsftpd, and when i connect to it from the server itself using my externel ip address, everything checks ok, and i can browse files. but when i try to do the same on a windows computer on my network, this is what happens: [my externel ip is blocked out with x]

[Code]....

now mind you, my linux server is running from port forwarding from my router, which is connected to the main computer, and i have ssh and squid running as well. not sure if those two have any affect on the service. i think this is a problem with the firewall, because i have read somewhere that multiple ports need to be open for a passive ftp to work.
