sendmail not sending after reboot
HI folks, I've an up-to-date CentOS 5.x box on a small intranet (<20 users). We did a reboot over the weekend and all appears well except that clients on the LAN can no longer send email. Just hangs/times out. No clear identifiers in the /var/log/maillog or /var/log/messages. We're not setup for ESMTP as it's a closed network and I'm really hoping for a kickstart as to

Sendmail using SMTP authorization
Hi - OK not really an Asterisk question but it is affecting one of my favorite features - emailing voice mail! I've posted on some Linux forums and sendmail.org but no response so I'm hoping someone will take pity on me ;-) My ISP requires SMTP authorization and I'm having a heck of a time getting it to work. I've included the following below: Asterisk 1.4.21 CentOS 5 Sendmail

Sendmail
I know this is a "generic" question, but fully CentOS related. I attempted to set up i386 v.4.1 on my primary computer at the co-located site, and thought I had everything squared away till I discovered the machine was refusing mail connections. AFIK, I had no firewall or other objects blocking port 25. It has been my experience that with most arch's and versions where sendmail is

Verizon DSL + rp-pppoe + CentOS 6.5
Greetings, I've just upgrade a home server to CentOS 6.5 with a new dual-core processor and mobo. I see that with the CentOS 6.x release rp-pppoe can be run as a daemon. I've looked through some online one-page setup notes for rp-pppoe, but nowhere is there a discussion of running it as a daemon. Until now, I've cobbled an ifcfg-ppp0 file and placed it in

C6: tcp-wrapping pop3?
Greetings, Per the subject line, how does pop3 get tcp-wrapped when using dovecot? More specifically, when blocking email and (still) using sendmail, entries in /etc/hosts.deny look something like: sendmail: xxx.xxx. etc (depending on the depth/degree) for vsftpd it's vsftpd: xxx.xxx (where the x's are parts of an octet) for sshd it's sshd: xxx.xxx for pop3/dovecot it's?

Disaster recovery recommendations
Greetings, I have three drives; they are all SATA Seagate Barracudas; two are 500GB; the third is a 2TB. I don't have a clear reason why they have failed (possibly due to a deep, off-brand, flakey mobo; but it's still inconclusive, but I would like to find a disaster recovery service that can hopefully recover the data.

Kernel Panic post kernel-2.6.32-504.23.4.el6.x86_64
Greetings, Today, I decided to reboot one of my CentOS machines after it had been running for 219 days. In this time, I had done yum updates several times. When I tried rebooting the machine, none of the kernels would work except for the oldest one. Here are the installed kernels: kernel-2.6.32-504.23.4.el6.x86_64 kernel-2.6.32-573.3.1.el6.x86_64 kernel-2.6.32-573.7.1.el6.x86_64

Using a CentOS 6 Machine as a gateway/router/home server
Greetings, I'm rebuilding a machine to function as a gateway/router to Verizon DSL. It has two NICs eth0 and eth1 (static set to 192.168.1.1). eth0 connects to the DSL modem. I've setup Verizon DSL usine pppoe-setup, and it works. I can connect from home machines to the server (192.168.1.1); while logged in to the server, I can connect to both the internet, and the home machines.

PHP Questions on move from CentOS 5.x to CentOS 6.x
Greetings, A malfunctioning disk this past week accelerated a lingering decision to move to CentOS 6.x from CentOS 5.x. Most of our content is functioning and being presented as it should be. However, there appear to be php-related issues. Basic squirrelmail (a php-dependent package) works correctly. However, drupal, and other php-dependent parts that call postgresql and mysql databases of

Using CentOS Wordpress rpms
Greetings, Apologies for my seeming daft naivete. I'm wondering if there any sort of conventions for using Wordpress on CentOS? Generally until now, I have had users install Wordpress from tarballs on a case-by-case basis. This means that you can have several different versions of WordPress operating on a site. With the RPM you have a version that can be consistent across multiple

Dovecot rpms: requesting a minor enhancement
Greetings, What's the process for requesting minor enhancements to packages? Currently, CentOS dovecot rpms ship w/o having tcp_wrappers enabled; to have dovecot compiled with tcp_wrappers requires adding one directive to the to the dovecot.spec file in the srpm. If the directive isn't there, then any dovecot upgrades via YUM/RPM require first to have the RPMs recompiled before doing

[Possibly OT] - General question: state of internet traffic
Greetings, I've read reports that there has been degradation in Internet traffic over the last month. Until today, I haven't experienced any. However, getting bank record data from chase.com here in NYC seems impossible. I also noticed erratic ftp behavior today; connections can be made but data can't be transferred. This isn't consistent, though. (I have a machine in LA while
