Ubuntu Servers :: Clients Can't Use The Email From The Outside - Configuration / Synchronize?
Mar 22, 2011
I have one local mail server hosted in Mdaemon in my office and ip is 192.168.10.2. My clients can't use the email from the outside. If they want to use the mail, they need to come to office. I want them to use from the outside. How can i set up the mail server. Do i need to host the server on the hosting? I want to synchronize with my local mail server. I don't have the public IP BTW.
Is there a way to use dhcpd to assign vpn clients their IP and configuration?
I'd like to have dhcpd listen on br0 (already set as 10.0.0.1) so that devices conecting through eth1 and tap0 (should I be using tun?) will get the same address pool.
I have been struggling to set up and learn to use an efficient way of task & event management. At the moment, I use Thunderbird+Lightning with Gmail (IMAP) and it works OK. I would like to add a smartphone to the equation - I know it isn't cheap and I'm expecting to pay anywhere between $100 and $500 for one - since my old phone is slowly dying anyway and I need this to work for... well, work. I would like to be able to synchronize through bluetooth or wireless at home or whenever the phone gets near my laptop, as well as (if possible) whenever the phone gets near a wireless access point. I don't want to use 3g or any similar services. I have had no luck googling so far.
I have tried synchronizing with Google Calendar, only to be disappointed by the fact that it doesn't support tasks. I think the distinction between tasks and events is an important one and it keeps my calendar organized, so I'd hate to have to give it up. I haven't chosen a phone yet, so I can adjust my choice to whichever brand or type (or OS) is best suited for what I need.
I'm having problems with emails containing HTML content. When Google downloads the email messages via POP3 from my squirrelmail server, the message does not display using HTML. I'm not sure if this is Google's fault or Squirrelmail's fault, but I've never had problems before on other servers running the same script and using squirrelmail. If I login to squirrelmail, I have the option to download the email message as an attachment. The attachment, if opened by my local browser, shows up as HTML content, and it is properly formatted. However, I'm using Google to download my emails and file them under my Gmail account. After Gmail downloads the messages, it shows up like this:
From To admin@domainRemoved.com Date Sat, Jul 30, 2011 at 6:07 PM Subject Pending Registration
<p><b> After registering your client via your server, please visit the following URL to send them confirmation: </b></p>
I really need it to show up properly once Gmail downloads the messages, as it takes a long time to login to Squirrel mail and download each message as an attachment. My PHP Code Headers Look like this: $headers = 'MIME-Version: 1.0' . " "; $headers .= 'Content-type: text/html; charset=iso-8859-1' . " "; $headers .= "From: $uname <$email>";
Someone suggested that I remove the from my script. I did, and now the email shows a from sender as www-data www-data@domain.com. Before, the from field showed up as empty. However, my PHP script is designed to change the sender's information to the clients that contact me. Thus, if customer A contacts me, the email should be from customer A <custa@whatever.com>. However, it's not being changed by the PHP script. It works on every other server but mine. I think my postfix configuration isn't setup properly? What needs to be configured on it?
I'm setting up SUSE 11.4 for a Windows 7 laptop user who prefers Outlook 2007 which is a full-featured email client and I'm wondering what is the "closest" suse/KDE email client I can set up to make this person feel right at home.
I've configured more email clients over the years than I care to mention so I am by no means a newbie at this so when I set up linux for a friend recently (10.10 on a laptop) I came across this problem, the install went wonderfully btw! The fix, long story short, if you are a sky broadband customer and are just setting up your email, you'll have a letter informing you of your email address, you log on to sky.com/resetpassword (or similar) enter some credentials and enter a password. This worked fine with the webmail, log in no problem, configuring a client (Thunderbird and Evolution) resulted in receiving a login failure with the message similar to 'credential failure' or words to that effect.
So after entering the password again and again, reading and re-reading the sky.com site instructions on setting the correct security settings, checking the correct ports, checking the correct settings to allow an IMAP connection from within the webmail interface and still getting no where I did this: logged into the webmail interface, then 'mail settings' > 'accounts' > then 'google account settings' then 'change password', this opens a sky.com reset password window. choose the my security question option and use this to enter a new password and this worked.
I suggest not using the 'my email address' and 'send an email with a reset link' option, this was attempted first and resulted in the same issue, new password set for the webmail but still not working with an email client. It seems that, and I'll be corrected by anyone who knows for sure, that their software is currently not updating all the passwords held if you use the 'reset password via email link'and neither did the initial setting up of the password work correctly either. My best guess is the passwords are going out of sync with their email servers not being updated correctly in all circumstances. Once I had reset the password as described it worked first time, so clearly there is something in this.
For info the settings for IMAP:
[code]...
outgoing mail settings:
[URL] security: use name and password connection security: use SSL port should be set to 465
I have an issue where postfix is setup to use dovecot auth and as far as I know it works, if i login using telnet to the mail server i can authorize myself y providing the base64 encoded user & password. so if i can login, why cant my email clients. have tried thunderbird and evolution. this is the mail.log relavant entries for sucessful login via telnet
[Code]...
Login by pop or imap works flawlessly that what i dont get. From what i see it SHOULD be working. It it changes things, im using postfixadmin, postfix, dovecot. passwords and info stored in mysql tables. passwords are md5 encrypted. I thought that may be the issue, but that dosnt make sence.
I have an email setup where all of the emails from our email host is downloaded to our Linux server using Fetchmail. Then some of the incoming emails are sent to an MS exchange server (server1.domain.com) using Postfix. What i want to do is to send a copy of all emails to Another server (server2.domain.com) for redundancy.Can postfix be configured to send copies out to both?
I have recently setup a new mail server and have simulated sending and receiving on the new email server. The new email server will replace the primary one.I would like to setup the new email server in parallel with the existing one.This way i can observe issues that might occur and be aware of what could go wrong. I want to received mail to be delivered to both mail servers at the same time.I would like to use postfix, exim i find a bit to difficult to understand.I have thought of using transport maps, the only problem is that you can only forward mail to one server at a time using transport maps.I think recipient_bcc_maps and sender_bcc_maps could work, i would just like ideas of how i can do this.
I am thinking about buying a domain name and hosting my web server.
I have seen pricing from $8 to $30 a year. Any favorites from fellow ubunters? Also this whole "whois" thing scares me, if I am correct my information I enter when buying the domain is enter into some big pool of information. People can find this information out and dig up important information. url Can I prevent this with private Whois or how do I set it up? This website examples some of my fears with this whole WhoIs thing, url whois/Private-Whois.html Does most/all domain registers come with email or just email forwarding or both? How does that work? At this moment, my only question about Web Hosting is how do I get Website Statistics as in: Stats, web analytics, web traffic stats and more? I will be web hosting through Ubuntu 9.10 gnome.
I want to ask a question regarding on the "locale" problem. I've searched a lot on Google, but I think there is no detailed information and logic explained this topic well. Someone may suggest use Preference->Administration->Language Support to add or change whatever language I want. I can't use this way beacuse:
1. I need try to push locale configuration to a lot of linux clients. 2. I want to know the detailed information of how to configure.
I have tried to find the most helpful page on the Internet and read some "man locale":
I administrat a school in Denmark, with around 40 clients runnig xp pro and a windows 2003 server, but i read about the possibility of running a linux server, with thin clintes that can run from the server, if it has network pxe boot.
I was wondering if anybody now any links to a good how to page, on what is needed on the setup side of the server, and clients. To make it work. And i have to use my dhcp from the win 2003 server. Is that possible.
Im having a problem with our pxe environment. We have around 200 clients per server to boot from tftp and when we hit 250 the service just freezes. So, our options are to either add more servers or move to a more robust protocol. Is this feasible?? How can clients boot from ftp?
I have got a 10.4 LTS LTSP server running as i needed it should do.
When i boot-up one of the terminal it sees the DHCP and starts loading from the LTSP all working ok.... when it gets the login screen some of the terminals get the box on the screen to enter the user name and password. the other terminal dose not.
The work around i have got is that i have to click on the blank screen at the bottom left to get the "pick a session" button then i can login and can login as normal.
When all the clients login all is well, And works as if the system was loaded locally its fast and at the mow its reliable. The only thing that is not working as it should is the log in screen.
i set up an ltsp server on debian squeeze. after a standard installation, sound doesn't work on clients.
[code]...
when i start iceweasel normally (executed on server side), i get sound on the client. when i start ltsp-localapps iceweasel, i get no sound on flash sites and videos videos.what's wrong ? with local apps, is it possible that the flashplugin-nonfree doesn't talk to alsa ?
I would like to know whether ldap can be used to authenticate wireless clients with my server.server and clients are connected to a wireless router and i am able to get wireless adapter work in my ubuntu. Is there any anything extra which is required or the openldap server will work for wireless clients?
I do not understand this command well. Yes, I have looked at man route and that whilst that gives lots of information about the switches I cannot see it in context. I have a server with two nics. One to the Internet (eth1) and one to the lan (eth0). I use pppoe and when it is running I get a virtual adapter appear in ifconfic called ppp0 which shows the public DNS and ISP session IP. I entered the command: route add -host (gateway IP) dev eth1 and get the Internet to appear on the server. However, I do not get the Internet to the clients. I have turned off the firewall to be sure that this is not the problem.
We have been using Ubuntu 8.04 with ltsp the server is Intel P4 with 2 GB Ram and the 8 client consist of either Atom or old P3 and P4. Now we want to increase the clients and want to upgrade to latest ubuntu 10.04.
I heard AMD does excellent job with LTSP but is it possible to have intel clients and AMD as a server. If not then which the best intel server I can have other than xenon (Bcoz of the price factor i dont want to go for that)
On a Lucid server, dnsmasq is happily running DHCP together with a local DNS; although, in setting up NFS, I seem to have a small problem... I have /etc/exports referencing the hostname of the clients but these IPs change when the DHCP lease is renewed. Unless I restart NFS or run exportfs, I cannot mount the exports on my clients. I know that it would be good to make the all the addresses static; however, I was wondering whether there is another way to configure NFS such as possibly adding in a script to continually monitor /var/lib/misc/dnsmasq.leases and re-export accordingly?
I must be very thick as i cannot seem to get my dhcp clients to connect to the Internet properly. on my lucid server i installed dhcp3 server and bind9, i can ping and dig all on the local network. on the clients however, as soon as i go out of the local network there's messages like "unknown host www.google.com" or "network is unreachable".
I've successfully built my server, and any fat or thin client that I connect to it boots wonderfully, with great response. I've gone through this exercise because we need a more efficient way of testing computers before delivery to our customers. So, I'm trying to run Passmark's BurnInTest. I've run it before with previous versions (9.something, I think) and it worked well, but I needed to build a new server so we can test more computers concurrently, so I figured I'd get the latest release.
My problem occurs when I try to run BurnInTest - it must have root access to test the local USB, parallel, and serial ports, and the optical drive. For the previous iteration I used a script that dropped into a local xterm session, su'd to a root session, and called the BiT GUI. In this attempt, the same scripts, even when I single-step them manually, results in 'authentication failure' when the su is attempted.
I have enabled the root account and created a password for it in the chroot /opt/ltsp/i386, and rebuilt the image, multiple times, no joy. Using ctrl-alt-F1 I can log in as root, and using dmesg I can see the USB device register when I connect it, so as far as I can tell the root account is alive and well, just not available in a local xterm session for some reason.
what cloud computing is and i think it can help me with some of my clients i want to switch my clients from a normal ubuntu server to a ubuntu cloud. as of right now i have to send out a bill to them and if they dont pay i have to shut down there service till they pay. what i would like to do is to have a cloud where i can sell them based on what they use not a set price like it is now. and have them be able to pay there bill on the cloud and if they miss the bill then the cloud can shut off there service till its payed.
i dont know if this is possible and i have looked everywhere and all i can find is info on other businesses billing and now how to set up a cloud to do this. i wish there was some kind of tutorial for this. if anyone can direct me to some good notes/tutorials that would be very helpful. this could be a big changing point in my business if i can do this. it would save a lot of time and cash.
I'm running a small ejabberd server on a LAN. Everything works fine out of the box except that when certain users disconnect they remain listed as online. Specifically, Linux users who suspend their computers with their client still open are still listed as online. This is not the case for Windows or Mac clients. I did some research and fount out that it has something to do with the TCP keepalive timeouts on the server. However I cannot figure out how to set those times.
I have an embedded server running Ubuntu which is on a network with a lot of wireless AP's. The AP's doesn't support SNMP or anything else, so I monitor if they are up or down by simply pinging them continuously.
My question is if there is anything I could install on the server that could provide me with a webpage where I could see the ping time to the AP's? So it just shows a list of the IP's I have told it to ping, and what their latest response time is. This is what I basically need, but if it were more advanced than that, and could give warnings if ping time were to high etc.
