All clients on the LAN, have to have their /etc/hosts file edited for my server to resolve their hostnames/LAN ip addresses. Both Windows/Mac/Linux. That shouldn't be necessary as all other stanzas are correct. If the hosts file is not ammended my maillog shows connect from unknown rip="my_external_address" when in fact it should say connect from "host" rip=192.168.0.20 Not to sure if it is an iptables issue as I have nothing for this configuration. /etc/hosts file on the server has all required hostnames and ip addresses
I am running CentOS 5.4 and Postfix. So when I start Postfix server than immediately maillog is starting to grow. And the first lines that I see in it are:

Server is already in several blacklists and I desperately need to do something.
I have a server A that needs to connect to another server (B) to transfer data everyday.[A] ==SFTP==> [B]
I am using SFTP for the data transfert between A and B. I configured B to allow authentication only with a key, not with password. However, anybody who acccess the filesystem of A, could steal the password.
So I thought I could password protect the private key from A. But in such a case, I need to store the password somewhere on A, so the server A can access the private key to connect to B. Finally, it is endless: i always have to store somewhere a secret on A. Is there another solution that allow to have an authentication between A and B without storing plain text secret on the server A ?
I'm using comcast, and I setup my server, everything works fine.But later I found out that the server inet address is changing everyday, and it makes my server almost not accessible.Is there anyway to fix that problem??
I have been finding a lot of "You are Not allowed to connect" messages in my maillog file.
and the email addresses are not in my forum database. I've check my server for rootkits and there are none installed and I've also used mxtoolbox to test my server as an open relay and it says it's not an open relay. however I am seeing bounces that show 'relay' and I wonder exactly what I'm looking at and and asking for some help in identifying the nature of these emails. here's a few examples and they seem to come in 'spurts" when I'm tailing the maillog file. there's never anything waiting in the queue to be delivered.

I wish it was under better circumstances...very morning at 6:25am syslog-ng stops logging, right after it attempts to log rotate. its odd... the daemon doesnt die... it gets a new PID, but doesnt write the output to /var/log/syslog.Yet if I manually restart or reload syslog-ng it works great... its just like it doesnt like the logrotate...I have googled around and tried a few things...first I changed the postrotate in the logrotate.d/syslog-ng

I am working on linux server with below specifications.Linux EDT 2008 i686 i686 i386 GNU/LinuxWhile checking the status of the server using the command 'opmnctl status' and when server is down the output is not getting redirected to file.I m using the command as,opmnctl status > abc.txt.
I have 2 Linux servers, both Red Hat Enterprise 4.
If I visit a page with links to .otf (Opentype Font) files on a Linux server (prod) and I click on one of them, Firefox renders the font. If I visit the same page on a different Linux server (dev), I get a "Save File" prompt in Firefox.
In Internet Explorer, I get the File Save prompt from either server.
It's probably a package that the prod server has that the dev server doesn't? I'm not sure where to start looking or what to look for.

I need to parse the file of same name which exist on different servers and calculate the count of string existed in both files.Say a file abc.log exist on 2 servers.I want to search for string "test" on both files and calculate the total count of search string's existence.For example if file abc.log on server 1 has string "test" 2 times and file abc.log on server 2 has string "test" 4 times.then the output will beStringName : Countexampletest : 6 timesNote : I have created the password less connectivity using ssh-keygen.

Can windows read files from a home file server with an ext4 file system? or do I have to partition the drive with the server (ext4) and an ntfs partition with the files on?
I'm trying to setup a print server in Fedora 13. I've made it using CUPS and when I send something to print from a Windows PC it goes ok. My main concern is to know where is the spool file stored when a file is sent to print. I've seen in many forums that it is stored in /var/spools/cups. What I only see here is a file name c000XXX with some information about the printing job. I'm using hold print for this printer and before printing out anything I can't find the spool. I've tried cups-pdf and it stores a pdf file in a route but this is not enough for me. I need to know where the spool data is stored in order to know from who is the job being send.
In case that NFS client of fedora is set to cache nfs file handle, where is the cache stored such as /var/lib/nfs?If it's stored in memory instead of directory tree, what command can I know the combination of file names and file handles with?OS in my test environment: Fedora Core 6
Here what I want to achieve. I have iso file images that I do not want to expand permanently via /etc/fstab, but instead via autofs. Then I want them to be exposed by HTTP and FTP. I am using CentOS 5.5 and below are the relevant part of configuration files.
