CentOS 5 Networking :: Daemons Is Not Responding

Jun 4, 2009

The server is a Dell 1650 1U server, which a fresh install of CentOS 5.3, formatting the drive in the process. It has two e1000 NIC's and based on the wiring eth0 is the public segment and eth1 is the private segment.Both nic's make a solid 100mb connection to the cisco switch, and I can ping both interfaces "just fine".

If I run nmap on a remote PC that is also dual-homed in this fashion, I get the same response as to which ports are open (essentially everything since I disabled iptables temporarily to troubleshoot this issue) on both interfaces, which would be the expected result.But... and here is the source of my confusion... I can see the server by pinging it, I can use SSH to make such a connection and log in, but I cannot get apache to "answer the phone" so to speak.Runing "tcpdump -i eth0" shows me that my browser on a remote PC is attempting to connect, but without reply.If I send my browser to the ip address of eth1, I get the default CentOS new web server page as is the norm.Nothing shows in my /var/log/httpd/access_log or error_log at all... apache simply isn't answering.The httpd.conf is the original, and the one line I attempted to 'adjust' was the "listen 80" line, which I added the ip addresses specifically, but that didn't change anything.I am unsure how nmap can indicate the port is open and there is a service behind it, when on the same PC that ran nmap, I cannot connect at all.Might anyone have a clue to toss me so I can work to figure this out?

CentOS 5 Server :: 5.3 Network Stops Responding?

Apr 24, 2009

after a update to 5.3 from 5.2 via the built in updater the system stops responding to visitors from the outside, http that is, but heres the odd part, if i say run firefox on the server the connection works also for some reason if i'm on the network with my own computer the connection seems to stay open but as soon as i stop using these the server seems to drop the conenctions, but as i said as soon as i go via my comp to the server via say ie it works right away.

this i tried yesterday:did a cold boot to see if some update had problems and actually needed a reboot even if the updater didn't say, after it started the connection seemed to be open for a good while, and not untill this morning from a outside source the connection is droped again, not been on my comp nor logged on on the server today yet.the install only has on it what i got from the dvd, and as far as i know it has all the updates on it since 5.3 came out.my network is built up like this:

CentOS 5 :: Nautilus Stops Responding With 100% CPU Use In Some Directories?

Jan 9, 2010

I was wondering if anyone else has noticed the following behavior lately. Sometimes, when I enter a directory, during the generation of thumbnails nautilus freezes up with 100% cpu use. It has to be killed. It will then happen whenever I try to enter that specific directory with nautilus (although access with Konqueror or command-line is fine). Turning off the previews allows nautilus to enter that directory (usually... once even that didn't work). If I create a new directory and move all the files from the troublesome directory into the new directory, I can enter the new directory with nautilus and it works fine, even with thumbnails turned on. I can even rename that directory to the same name as the problematic one had and it will work. Long ago this behavior used to happen very rarely, then it seemed to be fixed, and now it is happening again but fairly frequently.

I was just wondering if anyone else has experienced this and, if so, do they know what is causing it? A simple solution is to turn off thumbnails but I'd prefer another solution.

CentOS 5 Server :: Dovecot Postfix POP Not Responding?

Jan 2, 2011

I am running CentOS 5.2 on a server here in my home. It runs Dovecot and Postfix and also serves as a website host for a small website of mine. Everything works fine. POP, SMTP, Webmail, WWW, all works great and has for ages.Here's the issue. I recently reinstalled a clean copy of Windows 7 on a workstation in my home onto a new harddrive(I still have the old drive int he machine so I can boot to it as well). I setup the Windows Live Mail client to send/receive mail with my mail/web server. However, it won't connect to the POP server on my server machine.Here's the kicker. If I boot to the old harddrive that is running Windows 7, it connects fine to my mailserver and can send/receive just fine. I've checked, rechecked and rechecked and all mail settings on the mail clients on both drives are identical.

Note: The installations of Windows 7 on both drives is identical. Same computer name/ same credentials, same IP, etc. However, as I stated, I can send/receive email with my server if I boot to my old drive, but if I boot to my new drive, I cannot send/receive.

Ubuntu Networking :: Nfs Lockd Not Responding

Sep 29, 2010

I have been using 10.4 as a Linux NFS server to share it's storage with a number of Mac computers we use in the office. All the Macs are configured to connect to the Linux server using the mount_nfs command in terminal.I have been using this method to transfer files to and from the Linux server for a while. Today, I installed a number of standard Ubuntu updates / security patches per the standard GUI update tool.

Now, I'm getting "nfs server 192.x.x.x:/media/video: lockd not responding" error messages. I have not seen this error before, and I haven't changed anything else about the configuration of the Linux server or the Macs with the exception of the installation of the security patches.

Networking :: Host Not Responding To DHCP Request?

May 18, 2009

I am running a 2 NIC system with the routing table for eth0 allows user access to the internet,etc. and eth1 routes to another private network (192.168.x.x). eth1 is configured to handle DHCP requests.When a device connected via eth1 boots, it requests an IP from the DHCP server. Using tcpdump, eth1 is receiving the request but is not offering a lease.dhcp.conf seems to be configuring the DHCP service correctly. and dhcpd is running.The host is running Red Hat Enterprise Linux (Server Edition) 5.1. Perhaps I need to modify fire-wall rules (or disable them on eth1 altogether)?
