I am using this command (inside a bash script) to check if mailserver is running correctly (port 25)
# echo | telnet localhost 25 | grep "Connected to "
If it does not respond I receive an email alter.
It works good , but sometime it NEVER respond (neither after 1 hour) , so I receive no notification . DO you know alternative command to the command above ?
I want to run a mail server from within debian linux guest with vmware workstation xp host. The setup is a bridged network connection
Here are things that need to be done:
a)Configure the Guest with a static IP on my home network. Verify that I can telnet to port 25 of the Guest from a system on my home network.
b)Then configure my home firewall/NAT box to forward incoming connections on TCP port 25 to the static IP address I gave my Guest. Then test that I can telnet to port 25 from a system outside my home network.
c)After that I need to configure the appropriate DNS records for my domain so that outside hosts know how to contact my mailserver.

I believe I have most of the basics covered. But before launching into the the advanced set up, I want to see if I can get help with one thing I am finding difficult to understand.
In terms of my domain name www.example.com, do I have to do anything on my hosting company's side? That is, www.example.com currently have my web site and it is hosted on a private server at a hosting company. I have the ip address of the server. When I configured postfix, i used this same domain name in the configurations so I want to know what else to do to get it working.

View 9 Replies View RelatedI have Ubuntu Server Edtiion on my server. During the installatino, I choosed to install the mailserver.
I have already configured the MTA.
I also configured the MDA(Dovecot). After I configured the MDA and tried to login on squirrelmail, plenty of MySQL error was generated.
I deleted Dovecot and tried again to login on squirrelmail. Now, this message appears:
Error connecting to IMAP server: localhost. 111 : Connection refused
I have followed the guide for "The Perfect Server - Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]" and all is well, except.
I can send mail (to GMail) from commandline. I can send mail (to GMail) from any of the domains configured in ISPConfig3 through SquirrelMail (how ever terrible that looks, but functions) or IMAP/POP.
but....
I can't receive mail (from GMail) on any of the domains configured in ISPConfig3 in SquirrelMail or IMAP/POP.
I have my domains configured with proper MX records (just like I have them configured at work). I have all ports (80, 143, 110, 25, 22, etc) forwarded on my router that are needed.
I can Telnet to localhost and all checks are fine. I can send and receive from and to local domains on the same server, which makes sense. but
I can't Telnet from any external server to my server behind NAT.
Conclusion:
I figured it MUST be a network/port-forwarding problem as the external Telnet requests fails to my machine on port 25.
Tested my router if it would let met communicate through port 25 and it would.
So it must be my ISP, as I read in different posts.
Question:
Maybe I'm a n00b, but in all other posts the problems were with receiving AND sending.
My ISP responded that port 25 is blocked because of spam issues.
But I can mail (and even spam if I would like to) to external domains while I didn't do anything weird to make that happen.
The only thing I wish for is to receive mails and if you'd ask me, port 25 would be solely for outgoing mails, not for incoming mail deliveries throught MX?
An ISP surely wouldn't disable their customers in having a mail-server for incoming mails, as long as they would send out through their own smtp server to make sure they wouldn't spam the world?
Im using posfix as a outgoing mail server, here i want to distribute the mails to different ips to avoid the ip blacklisting. I found a solution by using multiple transports , but here one thing blocking me was i could not able to select a transport using regexp or pcre matching pattern, log says that
Code:
Jun 5 07:12:49 server postfix/trivial-rewrite[6079]: warning: pcre map /etc/postfix/transport.pcre, line 1: regular expression substitution is not allowed: skipping this rule
the transport used for this purpose is:-

I've been google'ing around recently for some good solutions for creating local yum "update" repositories without syncing entire repositories. (or adding hundreds of exclude statements in config files)
I have several boxes with a common base build (centos 5.5/x86_64), one has nagios3, another has apache, and another tomcat6 (also a couple of others) For tomcat and nagios I'm obviously using 3rd party repositories (jpackage, epel, rpmforge to name a few) Everything is installed via RPM from kickstart.
I would like to make an updates repository which contains the updates for everything that's installed (including centos base).
Updates will be downloaded on a separate box, but not sure how to get the list of packages required on that box where the packages are not actually installed. I've looked at reposync and mrepo, but appear to be syncing from what's available rather than what's required.
I was hoping that I can provide an "rpm -qa" output, compare this to a "yum list" or perhaps running "yum check-update" on a list rather than installed packages. I could then use the yum-downloadonly module to get the packages which have changed from available sources.
can i just copy/backup postfix mail queues in /var/spool/postfix and paste that folder back in after i done migrating all users and mails to a new mailserver?

I need a script that is able to check if a service is running or not. It has to do it automatic since it is for restarting a GameServer.
I tried to make one myself, but since the .x86 file has the same name for every server, it is hard to know a way to check if the server is running with the right process.
Is there a way to make a script which is able to check if a service is running (service has same name, but using other ports)

Anyone know a way to check if flash is running? From command line or script.
I've tried
Code:
But it also gives output if flash is blocked(by flashblock in firefox).
so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
unknown-hacker|544> count.sh 1 3
1
2
3
My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message

View 5 Replies View RelatedI'm having trouble trying to make a script. What I want to do is check if xScreenSaver is running in my user account. If not, run it. If it's running, kill it.
So this is the script I've made:

The problem is that I've echoed the output of $(pgrep -u $(whoami) xscreensaver) and it always seems to add 4 numbers to the pid, even if the pid doesn't exist. What do I mean by "doesn't exist"? That no xscreensaver is running in my user, and if I run pgrep -u $(whoami) xscreensaver in bash, I get not output, but if I run the command though the script, I get (for instance) 4050. If I run it again, I get 4054, and again 4058... etc. What the hell is going on with that?

My DVD/CD burner is rather old now (going on 5 years), and I've had some "quality" issues when I've been burning stuff for the past year.
CD's: When I play a burned CD in my car stereo, the songs have a "skipping" sound to them on the low-volume levels of the audio. I use K3b as my burning software, and it seems to be the best, but am I wrong? Is this a common problem?
DVD's: Specifically video DVD's. After converting the .avi to an image file using DeVeDe Creator, it gives me a file that has the .iso and I burn the disc using K3b. It's really hit or miss.
The question: is there a way to test the performance of my DVD burner to make sure it's working properly? Is there a way to calibrate the mechanism? I have a new External DVD/CD burner that supports "LiteScribe" (I could be mistaken on the name, but it's a technology that allows you to create a picture on the opposite side of the disc), but my INTERNAL is a 5 year old Lite-On.
Is there a unique command ( common to all Linux Distros, Solaris, Windows ) to know whether a service is installed and running on my system or not??
