CentOS 5 :: SMTP Test Fails During Qmailrocks Install CentOS 5.5?
Oct 2, 2010
I am trying to run though the qmailrocks setup on a centos 5.5 and I am running into an issue when trying to telnet to port 25:
telnet localhost 25
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
Connection closed by foreign host.
Everything else seems to be working (telnet to 110), and I turned off the firewall entirely, but I still cannot telnet to port 25. I also get a blank error within squirrelmail when attempting to send mail out (ERROR:Message not sent. Server replied: ). I apologize for not going directly to the qmailrocks forum, but they are currently closed down (due to lack of funds). I also am a newbie, so I apologize for the lack of needed information. If anyone has any ideas, please let me know what information you would need.

i opened up my browser to surf the web and a page popped up i had never seen before.Apache 2 Test page powered by centos. Any address i put into my firefox browser won't come up and i'm stuck on this test page and,i can't locate it on my computer to remove it.How do i get rid of it and more importantly how did it get on my computer in the first place?
For use on a test LAN, ie. security is not an issue, I need to install the most basic FTP server available just so we can share files back and forth between test hosts : launch FTPd, have it share a directory through either "anonymous" or a single, shared login/password?
I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.
I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

I am trying to install Centos 5.6 on a motherboard with a built in Marvel 88SE61xx drive controller.NO drive arrays are configured using the Marvel BIOS configuration utility.During the install CENTOS displays loading MARVEL_PATA driver and it waits and waits and waits.Looking on one of the system message screens I get the following types of messages:qc timeoutfailed to identifyI/O errorLink is slow to respondSRST failed errno=16ata4: reset failed - giving upAny ideas as to how to get CENTOS to recognize the drives connected to the motherboard Marvell controller on a NON-RAID configuration?

Im having a major problem with mysql-server failing to install.The installation stoppes on "Running Transactions" (have tried waiting for 10 minutes). When I use Ctrl+C an error appears:error: %pre(mysql-server-5.0.77-4.el5_5.4.x86_64) scriptlet failed, signal 2 error: install: %pre scriptlet failed (2), skipping mysql-server-5.0.77-4.el5_5.4
Not new to CentOS, which I've installed on a few servers. I'm trying to turn a very old laptop (11 years ?), Toshiba Tecra 540cdt (with the latest available BIOS), into a home server. It runs Windows 2000 fine, and was earlier running some Mandriva versions. I'm trying a multi-boot install, from CD1of6. It does boot from the CD, then shows: boot: Loading vmlinuz... Loading initrd.img... then reboots, and goes through the same cycle. I switched the hard disk, same result. I have problems too if I try to install the latest Knoppix. An older Knoppix, 5.1 with kernel 2.6.19, will boot.
I have a Toshiba A205 S5804 laptop that had Vista Home Premium installed. Tried to install Centos 5 (2.6.18-8-el5) and when I went through the install process, X Server failed to start so I had to go thorough the command line install. Once the install completed, it only booted to console.
The default resolution for this laptop is 1280X800 but I dont know if that is why or not. if anyone has a clue about my issue, please let me know.. I really dont want to install windows.
I wanna install adobe flash player with yum but it fails to download, I think there may be something wrong with the repositories. Totally, could you give me a step by step instruction for installing the flash player.. i have already tried downloading it from adobe web site for linux and rpm (yum) but i couldn't install it. i also had NOKEY letter in the result
I have a problem installing CentOS 5.5 over lan. I set up a dhcp3 server and it works, client got an ip. I set up a tftpd-hpa server and it works, client can boot the install image of CentOS 5.5 I set up an apache server and it seems to be impossible... In the installation marathon I clicked through the menu to the choice of the web server where my installation files are available. I enter the ip 192.168.138.1 and the path CentOS-5.5 and CentOS tells me "Unable to retrieve http://192.168.138.1//CentOS-5.5/images/stage2.img" . Thats right because the two slashes are not right. Where the hell come the two slashes from???
I just installed 11.4 via the net install cd. In the configuration step, the internet connection test fails. Why would this happen if I just installed opensuse using the internet? It looks to me as if opensuse can already figure out how to use my network card. I went ahead and skipped the test, but it still doesn't make any sense to me. Let's see if internet works once I'm logged in...
I have installed Centos 5.3 64 bit version and run yum update so the system is up to date. However, I have noticed the kernel version that is installed is:
uname -a Linux elektra.chemresearch 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
and when attempting to install from ATrpm.net the nvidia driver I get this message:
yum install nvidia-graphics169.07 nvidia-graphics169.07-kmdl-`uname -r` ... Missing Dependency: /boot/vmlinuz-2.6.18-164.2.1.el5 is needed by package 1:nvidia-graphics169.07-kmdl-2.6.18-164.2.1.el5-169.07-94.el5.x86_64 (atrpms)
Now, yum says the kernel is up to date so how can I get the nvidia driver rpms to install? The entries in /boot are:
I have checked to make sure that the update repo is enabled. There were quite a few updates applied after the initial installation and the initial kernel was updated as the yum log indicates and also the entries in /boot.
I have a dedicated server running CentOS 5, Plesk 9.2.2, SMTP Postfix and Courier-IMAP.The issue I have is that on all domains on the server receiving email works fine however sending email never seems to work. This is from email programs, my phone, webmail and PHP. None of them seem to be able to send email. If it is of worth Spam Assassin is running however I don't feel it is causing any problems.
In Red hat i used the nail command to send mail using an external smtp server without sendmail or other mail services active. My question is: In Centos 5 nail is not present but is present mailx in version 8.1.1-44.2.2
Is there a way to set mailx to use external smtp server ? because in many forum i get the string mailx -S smtp= etc.etc. but in my case the -S parameter generate mailx: invalid option -- S antoher question is there a an official repository to download rpm nail for centos ?
I have installed qmailrock on my CentOS 5.4, finishing installation until sucees to launch webmail via GUI (squirrelmail). but my smtp service (:25) is always failed to connect.I can telnet on port 110, 80, etc. But on port 25, the result is not shown comment 220 oK.when i check using : qmailctl stat here the result :
/service/qmail-send: up (pid 26403) 5 seconds /service/qmail-send/log: up (pid 26404) 5 seconds /service/qmail-smtpd: up (pid 26455) 0 seconds
FYI, i have installed postfix before, but i've un-install it using yum remove.
I'd like to have anything that tries to send mail locally on my machine (including crontab reports for instance) to be handled by my ISP's smtp server instead of my machine acting like it's own SMTP server. I've spent around 15 hours trying to figure out how to do this and I keep either getting into things that I don't understand, or hitting brick walls (for instance, I found nullmailer, but after installing it, it seemed like it would only work on Unix) Is there an application like nullmailer which I can use as my MTA to forward all internal mail to a different SMTP?

Mutt can only read email's from my gmail account, but no emails can be send through gmail to the Internet. I need some guide for Mutt , don't know how to configure it , for sending emails via my gmail account. I tried many muttrc conf files from the Internet and even tried to configure my own muttrc file , but still no luck. My windows xp box ( Outlook Express ) is configured and works with gmail account , but I would like to explore the power of Linux.
I am trying to see if a can get a centos 5.5 server setup as an smtp store and forward spamfilter by following the Centos Wiki and the freespamfilter.org guide by Mr88Talent at [url], which relates to another linux distro.
The spamfilter is essentially working! however, i have one issue with DCC.
I'm not sure if anyone else would be interested in a Centos version of Mr88Talent's tutorial, but a very rough and completely untested first effort is available at the following url: [url]
Any opinions on this setup or just a total slating of everything i have done wrong would be welcome as i don't want to waste time trying to use a setup that is just not going to be practical or reliable to maintain / keep operational.
I have read that yum update can break this type of system - which concerns me.
The intended use of the spamfilter is for a small business (only about twenty e-mail accounts). However, they still need to reliably receive e-mails (hopefully with less spam though).
The server I'm running is virtually stock CentOS - it's running on a xen virtual host, started as CentOS 5.1 (32 bit) when that was fresh, it's at 5.5 now and updated nightly. All packages except postgresql and php are from CentOS and EPEL.
I'm running dovecot on it, and for long time, squirrelmail connecting via localhost was good enough. All external ports were firewalled by the CentOS firewall (just 25,80,443,custom ssh are currently open).
Now I need to allow an external imap client to connect.
I have generated ssl key and configured the dovecot configuration and it should be good to go, but gosh dangit, I can't remember how to open the port in the configuration.
I did it before when I set up ssh to run on a non standard port after I got sick of constant brute force attack on port 22, but I can't recall what I did and the various tutorials I find online all tell how to do it with the GUI tool, but I don't have any GUI stuff installed.
Is I'm pretty sure what I used to open up my custom > 1024 ssh port, but I can't remember how I used it to open that port and it doesn't seem intuitive. Also, do I need to use 993? I'd almost rather use something custom above 1024, as long as thunderbird supports it (don't care about any other mail client)
Finally, my smtp server is postfix and port 25 is already open (but not an open relay, I check it about every 3 months). For requests to send mail from a client, I would really like some authentication of some type - as in only relays for IP addresses that have recently successfully logged in the secure imap port.
I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only. I had follow this how-to [URL] and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works. I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, I install VM player on it and run CentOS inside the VM Player.
I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?
