Ubuntu Servers :: Server Can't Make Outgoing Connections

Jul 17, 2011

I have a ubuntu 10.04 dedicated server that I am having problems with. It intermittently cannot connect to any other servers outside its network.

Code:

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
^C
--- 8.8.8.8 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7008ms

(I have tried a bunch of other ips too and none outside its network are pingable) I'm not sure if this is a problem with my server or a problem with the networking outside the server. I have been emailing my server provider and they keep on insisting the problem is with the server and that their network is working fine. Apparently all of their other servers work and they can login into the gateway and ping 8.8.8.8 from there. So they just want to reinstall the OS, but I thought I'd post here to see if anyone has any ideas.

Here is some info I have gained while troubleshooting: I haven't changed any settings at all on the server for months. I haven't done any updates for about a week. The strangest thing is that this is intermittent, there have been a few times in the last 24 hours where I have been able to ping 8.8.8.8 or other ips, but 98% of the time I can't. I have also tried rebooting the server, which had no effect. I can ping the gateway, and I can ping other servers on the same subnet. I can ssh onto the server from my home internet connection, and I can view webpages on apache, so incoming connections work.

Ubuntu Security :: Mobloquer Blocking Outgoing Connections?

Jan 18, 2010

Mobloquer starts up at boot and before I've even opened firefox or transmission or anything, mobloquer shows that is has started blocking several outgoing connections as well as ton of incoming connections. I was wondering if the outgoing connections is normal and what's a normal amount of network activity to show up in system monitor when I'm not actively using the internet.

OpenSUSE Network :: Monitoring Incoming And Outgoing Connections?

May 19, 2010

My question is simple - is there any linux app or applet which is able to show (monitor) incoming and outgoing connections assuming it's a direct internet access? I was using a firewall on a system off Redmont which was able to show every connection, listening ports of services if some were opened etc.

Ubuntu Networking :: Firewall - Block Incoming / Outgoing Connections To IP Range

Jul 4, 2010

I am still new to ubuntu and I use firestarter as my firewall tool and I was told that its just ufw in a gui. Well anyways I noticed a connection to 174.129.241.144 using https and python, I didn't have any scripts running and my browser was closed, I read the man files for ufw and it said to do something like deny from 174.129.0.0/12 and I want to block all incoming and outgoing connections to this IP range and I was wondering how to do that, I heard of iptables that it would be able to do this but I dont know anything about it. What I should learn so I can handle these kinds of situation in the future and how I can block this ip subnet or also what does the /8, /12, and /16 stand for?

Ubuntu Servers :: Multiple Connections To SMB Server

May 25, 2010

I'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)

Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction

Servers :: Ubuntu 10.4 Server Stops Accepting Connections After A Period Of Time / Fix It?

Apr 24, 2011

I'm not sure if this belongs in the Server or Networking section of the forums. Anyway, last month I upgraded my server to Ubuntu 10.04 LTS. Since then, I've had a recurring problem wherein after a certain period of time, the server stops accepting network connections. Ubuntu 10 will continue to reject network connections until someone logs into the server locally, after which time network connectivity is restored and the cycle begins anew. Essentially, the server goes into a "half sleep mode". I say half because the computer is still on and the fans are running.

I've done some searching around various forms and initially figured this issue was related to problems with the Network Manager service (https://bugs.launchpad.net/ubuntu/lu...er/+bug/524454), so I removed the service altogether. However, this problem is still occurring.

I've poured over /var/log/messages and /var/log/syslog, but have noticed no irregular behavior. Has anyone else experienced this issues? I'd rather not resort to downgrading back to Gusty Gibbon if I can help it.

I am happy to provide more information if its needed

Ubuntu Servers :: Slow Failure Of Network Connections In Server (as Compared To Desktop)?

Jan 13, 2010

I have two ubuntu boxes. One is a 9.04 desktop edition and the other is a 9.10 server edition I am working on some code that needs to be highly tolerant of bad network connections. It sends transactions to a central database, but when the network is not available, it caches them locally to retry later.

I have the code working beautifully on my desktop box. but when I test it on this other box (the one running server edition) there is a HUGE DELAY every time it tries and fails to send a transaction to the database when the network is down.

I tested a little further, and I found that if i unplug my network cable and run ping somehost on the desktop, it fails instantly saying "ping: unknown host somehost" But if I unplug the cable on the server box and run the same ping command it lingers for about 40 seconds before the ping fails.

Does anybody have any idea why this might be happening? Is this a 9.04 vs 9.10 difference? Is this a desktop vs server difference? Is there some package I can install, or some config setting I can change that will make the server box insta-fail just like the desktop does?

Ubuntu Servers :: Redirect All Outgoing Emails?

May 10, 2010

Here's what I'm trying to do to complete my rocking development server.

I would like all outgoing email on my Ubuntu server to be redirected to one email address (internal or external). I don't have any mail server installed yet (I'll probably use postfix unless you have another suggestion).

The reason I would like this to work is because I'm a web developer working on multiple projects. When I start working on a new project I would like to be able to test some of the forms and features in the web application (PHP) without having emails sent to the email address configured in the application. I can always change configurations but having my development server forward the emails would save me lots of trouble.

Example:
If one of my php application sends an email to: user1@domain.com, user3@domain4.com... I would like all of them to forward to myemail@domain.com

Ubuntu Servers :: Outgoing Mail ALWAYS Flagged As Spam

Mar 2, 2010

I've got a web server that's hosting a few sites, and there are a few WordPress instances with these sites. With Wordpress, whenever a user registers with the site, they receive an email.With my server, it sends mail via Sendmail. This is all fine and good, except no matter what, it's flagged as spam. Is there any way to correct this?Keep in mind that this isn't a mail server, and the only reason the server ever sends mail is for new wordpress users and password resets.

Fedora Servers :: Setting Up An Outgoing Mail Using 587?

Oct 25, 2009

I have a small home network running mail agents Evolution and Thunderbird, and connected to the internet via Comcast. Originally I used my campus office computer as a mail server, but encountered problmes because Comcast started blocking port 25, allegedly because of span problems. I need to change the setup on my campus office computer so it uses port 587 when functioning as an outgoing mail server.

Can anyone recommend a tutorial which tells me everything to do in order to accomplish that?

At present I'm, using Comcast's outgoing mail server, but I started having problems with sporadic blokage of outgoing mail with attachments, which Comast can't explain.

Fedora Servers :: Can't Send My Outgoing Mail Using Port 587 / Why Is So?

Dec 10, 2009

I have installed a sendmail server on fedora 10
I try to configure my sendmail server as a mail server to send outgoing email using port 587( because port 25 is blocked). after finishing configuring my sendmail server, i checked out my sendmail server using telnet localhost 587, and it worked fine as below code...

I have tried two different ways for user name: name, or name@mail.mydomian.com, but not working at all, the two results are the same.
PS: I have test port 587 and can use port 587 and Kmail to send outgoing mail using other external relay server

is my wrong configuration for sendmail server or kmail?

Ubuntu Servers :: Make It A .com - Redirect DNS To Server IP?

Oct 26, 2010

I'm hosting my own dedicated server with Ubuntu Server 10.10. I have it set up with a static local IP, and I've configured DynDNS to link up with my router and allow my server to go live to the internet. I have all the appropriate ports unlocked, with the exception of port 80. This port is blocked by my ISP (Charter) and I can't use it. Due to this, I configured my router to listen on port 81, and direct it to my server.

So, In order to view it, you need to go to the IP XXX.xxx.XXX.xxx:81 Today, I registered (www.online-self.com) in hopes of getting around my current mask (provided by DynDNS.com (omegame.selfip.com). So here is my dilemma, When I go to the host of my domain name , I want to redirect my DNS to my server IP.

I can't seem to do it though? They want a strict IP address, no port extensions. How do I get around this so that my domain name and IP address link up? I'm thinking I may be missing a step, or maybe I needed to register a domain name that simply redirects? I'm starting to get confused on what I should do next. Can I even do this?

Ubuntu Servers :: How To Make The Server Route Between

Nov 9, 2010

For the last couple of days I've been building on a server built from an old (well, not too old) computer. My goal is to use it for multiple purposes like a webserver, home automation, and possibly a future media center (if I get my TV card to work). But perhaps the main reason is to get wireless access to the internet for my laptop, and to connect it to my other (stationary) computer. When I'm done I'm also planning on writing a guide for setting up an access point with the rt61 chipset, as there seems to be many people looking for this. First I just need to get through this problem though .

For this I use two wired NICs, eth0 for the local interface to my computer, and eth1 as an external interface for the internet. Moreover I use a wireless NIC (DWL-G510 using the rt61pci driver) in conjunction with the daemon hostapd to provide a wireless interface for portable computers to connect to. eth1 gets its IP through DHCP from my ISP, while eth0 and wlan0 have static IPs on two different subnets like this (copied from /etc/network/interfaces):

Code:
auto eth0
iface eth0 inet static

Server :: Unable To Connect To Outgoing SMTP Server

I can send mail off-server just fine if I log in via telnet. I can receive email just fine with Thunderbird.

message_size_limit = 102400000
mailbox_size_limit = 1024000000
