OpenSUSE Network :: Can't Access The Smtp Servers

May 22, 2011

It seems I can't access smpt servers both from kmail and php. Kmail says

Code:

Sending failed:
smtp.gmail.com

The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.The following transport was used: ... I double checked my settings and they are correct. I can ping smtp.gmail.com. I can send emails using thunderbird on a windows box that is connected to the same network as I am.I also tried turning off the firewall through yast but no joy.

My postfix is ok with receiving emails but i can send mail to my domain only [URL] When I want to send to other domains i receive this error (in the maillog):

OpenSUSE Network :: Setting Up Custom FTP Servers - Access To The Cstrike Folde Via A Ftp Login

Apr 2, 2010

I dont know were to begin to solve my problem and I have been googling for hours to get a hint without any success. I'm runnning a Counterstrike Server on my virtual openSuse server - I'm exploring so don't justify what I am hosting at the moment

I want to make it possible to gain access to the cstrike folde via a ftp login. But I really have no idea were to start. The server is also a webserver, where I can ass FTP accounts for my apache vhosts via plesk - but I dont think this is the solution of my problem, isn't it?

OpenSUSE Network :: SMTP - No Route To Host

Jan 3, 2010

OpenSUSE version: 11.2 *and* 10.0 I am unable to send email. It appears I am being blocked by my ISP [URL]... A Wireshark trace shows ICMP type 3 Code 13 - "Administratively filtered". It's important to note that I don't know exactly when the problem started, because I seldom use my ISP email account, I use Yahoo web mail due to the "throwaway" nature if I get hit with spam. I only discovered the problem when testing the functionality of 11.2. I suspect the problem started several months ago: I restored openSUSE 10.0 and the problem exists there too. I wish I'd sent that last email via 10.0 before the upgrade.

The weird thing is that using Windows 2000 box I can get a successful connection using telnet (Telnet also fails on the openSUSE box.) It appears to me there is something in the Linux TCP stack that Teksavvy doesn't like. I am on dial up and I pointed this out to Teksavvy tech support, as I am probably the only person left on dialup and the reason no one else has reported the problem

OpenSUSE Network :: Blocking SMTP On Firewall?

Aug 19, 2010

Ok here's my setup :

SuSE 10.0 X86 32 acting as my internet gateway and firewall.

eth0 is my internal interface network 192.168.0.0/24 IP 192.168.0.254 dsl0 is my internet connection and is a single ip PtP connection to my ISP.

My internal network is masquaraded onto the external network.

I run an smtp server on my gateway box that I need to be accessable to both the internal and external networks.

However I want to prevent machines on the internal network from establishing connections to external smtp servers, but still alow them to connect to the smtp server on the gateway to send email.

NOTE I do not want to force attempts to connect to [URL] 25 to be re-directed to my internal server I just want to drop or reject the connection.

The firewall up until now has just been configured through YaST, but am not afraid to edit script files if needed

The reason for doing this it to prevent spambots from being able to send through my isp, I keep my own machines clean but sometimes get asked to disinfect machines for other people (family members etc), where I need to connect to the outside world to get updates/virus defs etc, but don't want them spamming from my network.

OpenSUSE Network :: Specifying Smtp Relay On Commandline Of Mail Command?

Aug 9, 2011

On my opensuse 11.4 box (although I assume the version is irrelevant), I'm trying to figure out how to do something with the mail command. We have multiple smtp relay servers and sometimes I have to test to verify that mail is bouncing off of them successfully. On my laptop, in my main.cf file for postfix, I've got the relay server listed. But to test multiple servers, I have to change the main.cf, restart postfix, send message, and then repeat for each test.

I'm trying to figure out a way to specify the smtp relay on the command line. I've been playing with the -S option which is supposed to allow variables and one of the variables in the man page is 'smtp'. I've tried several different syntaxes but nothing seems to work.

The closest I've come is:
mail -S smtp 10.1.0.63 -s "test" user@email.com < main.cf

That syntax doesn't give me an error but it still routes the message off the smtp server listed in main.cf which is not 10.1.0.63.

Ubuntu Servers :: Two Network Cards / Can't Access Internal Network

Feb 25, 2011

I've installed Ubuntu Server 10.10 with two network cards. One for external, and one internal.My problem is that as soon as i activate eth1 (external), i can't access the server from the internal network (eth0)

With these settings i can't reach the internal network from inside.If i disable the gateway on eth1 and enable the gateway on eth0, it works.

OpenSUSE :: Does KMail Account Data - Such As Login Data / Names Of Pop / Smtp Servers

Oct 6, 2010

Where apart from ~/.kde4/share/apps/kmail does kmail keep account data, such as login data/names of pop/smtp servers? I wanted to install an entirely clean version of kmail, so I uninstalled/re-installed kmail via YAST. I manually deleted ~/.kde4/share/apps/kmail. After installing kmail I found that the account data of my Yahoo account were still listed in the kmail configuration panel. Shall I delete the Yahoo account within kmail prior to uninstalling the kmail package?

OpenSUSE Network :: 11.3 Amd64 - Having Internet Access But Cannot Access Repos - IPV6?

Aug 26, 2010

I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message

- download (curl) error for (repo)
- error code connection failed
- error message could not resolve host (repo)

This was followed by a message box containing

- UI syntax error
- no widget with ID 'contents

Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)

OpenSUSE Network :: Two Network Cards With Different Settings For Internet Access

Feb 9, 2010

I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.

Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.

OpenSUSE Network :: Network / DNS - Can't Access Any Internet Resources Or Router

Jul 30, 2010

I'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.

I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager

Ubuntu Servers :: FTP Access Inside Local Network Only?

Jun 8, 2011

I've been researching this all day with no luck thus far. Basically I need to cutoff port 21/ftp access from IP addresses outside of my local network. My local IP range is something like 192.168.0.100 - 192.168.0.150 -- so anything outside of this range would automatically be blocked.

Any IP address outside of this range would be denied as I use SFTP for remote access, etc. from home, etc.

I've researched IP tables, tcp wrappers, etc. but am still unsure which would be best for what is probably a simple fix.

Relevant info: Vsftpd via Ubuntu Server 10.10

Ubuntu Servers :: Use Ipv4 Forwarding To Access LAN Network From The WAN?

Jun 11, 2011

I have an OpenVPN(10.04.2 LTS) server running in bridge (TAP) mode. Its sitting behind a router and then a cable modem. The VPN works perfectly but I have a security concern. In order to allow the VPN clients to connect to the internet, I had to enable IPv4 forwarding on the server. Is this is a security hole? Can a hacker access my servers connection from the internet (without authenticating with OpenVPN) and access my network. Can someone use Ipv4 forwarding to access my LAN network from the WAN

I used this command to enable ipv4 forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward

Without IPv4 forwarding my VPN clients can only access my LAN and router, but they cannot reach my modem or the internet.

OpenSUSE Network :: SUSE 11.3 No Network Access With Static IP

Aug 20, 2010

New SUSE 11.3 install connects to network/internet etc OK with DHCP-assigned IP address. When I switch to static IP, I can no longer ping internal network, or anything else. This works OK with SUSE 11.2 on same hardware and (as far as I can see) same setup. Some diagnostics are shown below.

Firewall
Disabling the firewall makes no difference.

Not using a network manager (can't see how to assign fixed address if I do - all greyed out).

ifup eth0:
eth0 device: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
SuSEfirewall2: Warning: no default firewall zone defined, assuming 'ext'

Debian Configuration :: Network - Access Servers Request Failed

Feb 1, 2010

I recently installed two PC with debian lenny (kernel 2.6.26). One is called serveur-debian1 and the second one serveur-debian2. I have installed gnome,samba, mysql5, apache2, php5, and Virtualbox,bridge-tools on them. On serveur-debian2, i installed an other virtual debian lenny with apache2,mysql5,php5,nagios and centreon on it to view my network. I remember having installed a soft to access nntp on serveur-debian2 in order to test nagios.

Since a few days, i have problem to access to my servers. rom my windows 7 client, i try to ping serveur-debian1. Response is OK but not for all resquets Always from the same computer, i try to ping serveur-debian2. Response is OK but not for all again.

When i launch a ping on serveur-debian1 and serveur debian2 at the same time i have:

ping 1 to 10: serveur-debian1: response OK
serveur-debian2: no response
ping 11to 14: serveur-debian1: no response
serveur-debian2: response OK
ping 15 to 25: serveur-debian1: respone OK
serveur-debian2: @ip serveur-debian1 network unreachable (there's no error, it shows me the ip of serveur-debian1)

If i switch on the debian virtual server on the serveur-debian2, and i ping it at the same time, the response is OK for all resquests. The problem is very strange. I can't have a correct connection and when i launch a request from a software which access the mysql server, the requests failed ...

Ubuntu Servers :: Apache Setup For Hostname Access On Local Network

Apr 13, 2011

I have installed Ubuntu on four machines at work and have been blown away. On my machine I have Apache setup for web development and other machines can "see" it using my IP address. I would like to have it so they can access by the name of my computer though. I have no local DNS server so I guess I need to hard code the relationship in each machine? Ideally I'd actually like to be able to use subdomains (which I use locally to avoid annoying .htaccess path problems). i.e. from another machine on the network to go to [URL].

OpenSUSE Network :: Not Able To Connect To Update Servers And Some Servers On The Web

Dec 16, 2010

Problem with my Internet connection. I can't connect to the update servers. I don't know why. It's a brand new installation, not a week old yet. I can't install the support for restricted media for example. The servers won't refresh in YaST. It tells me it can't download the repomd.xml.asc.

The other problem is that some servers on the web won't load for me either.

For example, I get most of my local news from The Toronto Star, and I can't connect to it's website at all.

I can from Windows (I dual boot) but not SUSE. I don't think its a problem limited to that one website either. I am able to connect to most websites though.

This is the result of zypper repos -d

Ubuntu Servers :: Sent Out From Gmail Via SMTP

I run a 6.06.2 Dapper server for a not-for-profit, and have had a very simple email set-up working for a couple of years. Users have their email address set up on the server, and use a gmail account as webmail access/storage. Emails are downloaded via POP to users gmail accounts, and are sent out from gmail via SMTP to the server. Like I said, this has worked fine for ages, but in the last couple of days its all gone wrong.
The SMTP log I get for an email I tried to send from gmail is as follows:

Fedora Servers :: Set Up An External SMTP Relay Box?

Jun 29, 2011

I've tried googling this, and am having trouble finding something that doesn't end up being dizzying or confusing.

I was wondering if anybody could provide me with a concise, conclusive answer/guide.

I have a set of servers which require redundant SMTP relay. The first two of their SMTP relays are their own SMTP servers, and as such, are not dependable in the event that their network/servers go down. Their monitoring software runs on their machines as well, and uses the SMTP servers they themselves host.

I need to set up an external SMTP relay box that they can use to relay their monitoring alerts/admin notices in the case that their mailservers go down.

I have a company exchange server with pop/imap support @ my disposal but, unfortunately, that box runs Windows and does not permit any changes to services or additional software to add for the purposes of relaying clients.

So now, I need to create a dedicated linux box that can act as a relay to send email coming from the monitoring/admin/alert software in case their first two smtp servers have gone down.
