Networking :: Determining Inbound Vs Outbound
Mar 14, 2011Looking at the output of netstat, I'm not seeing a definitive way to tell which torrent connections are clients reaching in to my machine vs my machine reaching out to the world. Is there a clear way to determine which is which?

Jun 2, 2011I'm having an issue where a server in CA (1000/full) and in VA (100/full) have very lopsided data transfer.
CA -> VA with iperf shows ~20Mbps
VA -> CA with iperf shows ~93Mbps
If we change the CA server to 100/FULL, transfer speed is 93Mbps both ways.
Some tuning was done to TCP window scaling parameters, but it won't correct the issue, just improve the CA -> VA numbers to what is listed above. I will say, turning TCP window scaling OFF will lower the transfer speed both ways to < 20Mbps.
The only clue I have when looking at wireshark dumps is that the window scale going OUT would never go past 10240 (scale is 8, so 2^8 x 40bytes). In the opposite direction, the window size will go above 3MB (scaled).
It is not a bandwidth problem as iperf with UDP shows 93Mbps both ways. Local transfers (CA 1000/full to CA 100/full) show full speed both ways, so I feel it is strictly related to TCP window scaling.
RedHat 5 64-bit on both sides. Any ideas why it won't scale above 10240?

View 2 Replies View RelatedServer :: Combine The Dovecot And Inbound Postfix Servers?
Jun 13, 2011We are planning on rolling out a mail service that will backend a webmail/groupware interface using postfix and dovecot, and we are trying to nail down an architecture for the system. I was hoping I could get some opinions from you good people on the different models we have come up with, and any improvements. To preface this discussion, we use NFS as the backend storage for mail so that clusters of mail servers can be created.
One possible solution is to separate three services, inbound email, outbound email, and message retrieval onto separate servers. We currently run a mail system with 65K users in this manner and it works, but there is a lot of wasted cpu on the inbound and outbound mail servers. where the dovecot servers are doing most of the work.
Another solution would be to combine the dovecot and inbound postfix servers to run dovecot as the local transport agent for postfix with LMTP, giving us quota and sieve capability.
The last solution is to run all three services on the same machine, giving us a single server image that we can clone on demand when we need to add more performance.
The single server, all three services, solution seems to be the simplest to build and manage, but putting all your eggs in one basket like that concerns us. What if there is a sudden influx of mail from our filtering platform, and it slows down all the other processes? What if the NFS server becomes disconnected from the network and the load average on each server skyrockets killing the ability for outbound mail to flow (where a separate outbound mail server would continue running despite this issue)?
Server :: Redistribution Of Inbound Syslog Messages To Syslogd?
Apr 28, 2010RHEL 5.4 i want to be able to do redistribution of inbound syslog messages to syslogd. as example, my syslog.conf has in it at the end:
*.* @192.168.5.5
*.* @192.168.5.6
my sysconfig/syslog file has "-r" as the only option for syslogd. any messages generated by the localhost will be sent to the two remote servers, but messages that come into this box (udp 514) only get logged locally and do not get sent out to the remote hosts.
you may ask why do i want to do this. because i have several syslog servers (for security purposes) and many of my net devices are configured to send syslog to all the syslog servers, hence each device is sending way too much duplicate udp-514. so i would like to minimize the udp-514 coming out of the devices, have all devices send to a central syslog server, and then central syslog server do distribution to the other syslog servers. others have also called this "syslog proxy". or, if not with syslogd, how to achieve this (preserving the original syslog message host info, etc)?
Server :: Sendmail For Inbound Mail And Redirecting Them Internally To Other Port?
Mar 22, 2011I have configured a sendmail MTA for incoming mails in a network and by using IPtables i have redirected the traffic internally to other port where one more SMTP by a application is running.Iptables rule:
iptables -A INPUT -i eth0 -p tcp --dport 25 -j ACCEPT
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 25 -j REDIRECT --to-port 25000
My sendmail config is as below.

Ubuntu Servers :: Setup An Outbound SMTP Mail Server With & Using Multiple IP Addresses
Mar 15, 2010This is the current setup that we have: We have approx 20 clients who pay us to send out a type of e-mail called an E-Blast to their customers. We currently are using 5 Microsoft Windows Virtual Servers to do this. The problem is that those machines are starting to break down. There are times that it will take Microsoft Windows approx 9-10 hours to complete 1 job. This is way too long. We want to move away from Microsoft Windows for this particular type of job as it seems there are more customers who are wanting to use this type of advertising.
It seems that using a Linux Server "Command Line or Shell" environment would be the best way to go as there is no GUI like Windows. Since there is just text...that is something that would/should process very, very quickly.
I am in the process of setting up a new SMTP outbound mail server. This is the current software & configuration (what is installed on this new machine):
All of the customer data (Names, E-Mail Addresses, etc that these e-mails are going to) are currently loaded in a Microsoft SQL Database.
My machine that I am using is plugged into the DMZ. I have 1 ip address for the 1 network card. I have also added/bound 4 more ip addresses to that network card.
I have configured Postfix for Multiple IP Addresses.
I can, from the command line, send successful test e-mails and receive them in my personal account.
As far as I know everything is setup correctly. I can and will post requested information so that it can be verified that everything is setup correctly.
Here are a couple of my questions:
Ensure that I have my Network / Interfaces file and my Postfix's Master.cf/Main.cf files setup correctly?
How can I setup this server to be an Outbound SMTP server and get it to use all 5 of the IP Addresses to send these e-mails quickly?
What can I use to check and ensure that this server is in fact sending out emails on all 5 IP
Addresses (I heard that there is a program named "Postal" that may help in determing this).
Server :: Configure Internal Zimbra Server To Use External Server To Send Mails?
Feb 16, 2010I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?

View 1 Replies View RelatedServer :: Mails Not Sent By The Shop System?
Jan 12, 2011We have an external server that runs HTTP/DB servers for out shop system.Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010.The shop system on the external server needs to send mails to customersrder confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address.My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly.So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts.This is what i get in the mail.log:The successfully relayed mail sent by the shop system:Quote:
