using a terminal on the server,telenet localhost 25 should connect to my mail server.It times out yet I can telnet remotely to my mailsever and get connected.I removed Iptables and that does change things.what ever is causing this started a week ago fri.I was adding to the iptables.I am still a newbie to Linux and Centos so I probably messed it up.
View 2 RepliesI've got a box with a fresh installation of CentOS 5.6, but had several configs copied from an old 4.8 box that I've now got to finish. Most everything seems fine, but I can't get apache running. It reports that it starts up fine, but immediately stops and reports "httpd dead but subsys locked"Most of the advice I've found while searching suggests to just delete the http.pid file and restart, which doesn't help in my case. I did find a few problems where SELinux was restricting httpd from creating or touching certain files (I found reports in /var/log/messages) but I've worked through that.
So the big question here is: /var/log/messages and /var/log/httpd/error_log are now empty, and don't show any more errors when I restart httpd. Does anyone know where else I can look for reporting/logging on what's happening to httpd to cause it to die?

Is there any way to setup the Centos Directory Server without an internet connection?? i tried using the command: yum install centos-ds
but this just tries to connect to the internet to to download the packages. Is there a site where i can find the package so that i can copy it to my server and install it or is there some other way to do this?

View 2 Replies View RelatedI have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
View 5 Replies View RelatedI have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.

For some reason, I can't seem to get the videocard to use the native resolution of any monitor I plug in, no matter what EDID information passes by the hardware. The hardware built into this server is a S3 Savage4 8MB. I tried to use the EDID info to create Modelines in xorg.conf, but it seems these get ignored outright Trying to reconfig with different drivers, the only ones that work (properly) appear to be VESA and SAVAGE (S3 and S3ViRGE didnt work). XRANDR wasn't much help either, it listed many short modes, maxing at 1024x768 Modes available:
1024x768
800x600
640x480
Monitor Modes of Monitors Tested available and in EDID, which CentOS/Xorg/whatever is ignoring:
Olevia 237-S11
Native Size: 1360x768
Resolution Maximum: 1920x1080 (downsample)
[code]...
All three of the monitors above, even with reconfigure and their best-bet drivers failed to offer anything but those three resolutions I listed above. Can anyone clarify for me if I'm missing something, or was the way the Savage driver coded that it is limited to 1024x768 maximum, regardless of panel and videocard capability?
but I think I have a reasonable handle on the /etc/init.d, /sbin/service, chkconfig, and runlevels stuff under CentOS. However, when I install particular daemons (not part of CentOS distro), I get a weird issue. If I log in as root and do /sbin/service <daemon> status, it says "... is running...", however, if I log in as a non su, and do the same /sbin/service ... status, it says "xxx dead but subsys locked." Is the daemon running or not? I assume it's some kind of privilege issue with how the daemon is setup versus the non root login.I would like to have users be able to use service to query daemon status as works with the base daemons like sshd and httpd.

The word on all lips are "virtualization" so I decided to smell this flavor.
I have a machine running CentOS 5.3 64bit and I have unlimited access to this machine, but I don't want to reach it physically.
Is it possible to install and maintain a virtual medium using ssh or other remote connection?
When I installed the OS I have selected the packets regarding the virtualization, but now from where can I start?
Is somewhere a guide for doing this?

I have 2 different networks :the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping [url]..... on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7, CentOS 5.
I could say that the problem in DNS:because when I use this command in the private network machine: [url]...., it says connection timed out; no servers could be reached ,while in the public one, it works properly.....
I have a fresh installation of CentOS 5 I'm using for a server, and I'm having issues with port configuration. I have iptables running, and it started with no /etc/sysconfig/iptables file. I added a few basic rules (port 53, port 10000 for webmin), saved the file, and restarted the service. I tried connecting to webmin, scanned ports, and traffic was blocked. I set iptables to allow all traffic and restarted the service, and it still showed basically every port as being blocked. It seems port 80 and port 22 work for some reason, even when I tell iptables to block all ports.
I'm not sure what's going on here. Iptables is reading the /etc/sysconfig/iptables file, and if I use lynx localhost:someport it responds as it should according to the file. However, if I try connecting by IP, it's like there's some other firewall or something running that does whatever it's configured to do.....
I just installed VMware server 2.02 on a CentOS 5.4 machine. I tried to run 'vmware': it starts via my web browser (firefox) with xdg-open. Then, firefox displays this:

I'm familiar with linux (Debian/Ubuntu), but new to CentOS. I recently installed CentOS 5.2 on a new server for my radio station. I can log in and do everything fine, save connect to any network. I only have a Broadcom wired nic. I know the wire and ethernet jack work fine, so that lead me to the server's settings. I'm not sure if I missed something somewhere, or a similar post (I'm sorry for double-posting if this has been done before).
There is a static IP address set, and that's done correctly.
From what I've seen, someone would like to see /sbin/lspci | grep -i ether: 03:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5722 Gigabit Ethernet PCI Express
I'm trying to setup a ssh connection from to my house that way I can learn Linux on a box that won't make my boss the sys admin (Im help desk) grind his teeth. He say that ssh port is allowing connections out of the firewall but not in so I can connect to my house. However If I try to connect to my box I get a message stating that the connection has time out. I have port forwarded the 22 to my box and have even changed the port to see if it is my isp blocking me. I am able to connect via SSH internally but when I try outside my house I am running into trouble. I looked up how to disable my fire wall and as far as I know it is.

I understand this is a command level and have been advised to use OpenVPN which I have successfully installed.My problem is I only have the details remote ip address, username and password.
