I have reinstalled CentOS 5.5 on my un-managed VPS. Everything is fine except port 80
I am trying to access IP address in Internet Explorer but seems port 80 is not accessible.
I have checked by changing Listen 80 to Listen 90 in httpd.conf
and accessed the ipaddress with port 90 i.e. 208.89.213.70:90 and apache page was displayed
I need help on how to resolve this issue

Have previously moved my ssh server from 22 to 4455 just by moving the port in sshd_config. This is done to minimize the log entries resulting from brute force attacks.However, it seems like Zimbra and other local services expect to find the ssh service locally available on port 22, so I figured it's better to move the port in the firewall so that it remains configured on port 22 in sshd_config, and instead use iptables with a nat/port rewrite to move 4455 incoming to 22 locally.
Isolated this works as long as I also keep allowing port 22, but the moment I close port 22, port 4455 is also dead, which sort of defies the purpose
I am on home internet access so it does not have a fix IP. I would like to set my web server to be accesible from outside. So what I do? First I must set my router to point access for port 80 to this machine. Then in the machine I open port 80 right? Then what software must I install is it no-ip?

I want to access my Linux box remotely on the internet via my VPN tunnel. However I am not sure what I need to do on the Linux box to make this happen. My linux box is multihomed as follows
PSTN WWW <===========> ADSL Router Firewall <----------------> [eth1 192.168.x.x] Linux Box [eth0 172.16.x.x] <-----> to LAN
The desired topology is as shown.
VPN Client <------> Home ADSL Router <======= PSTN WWW =======> ADSL Router <------> eth1 Linux Box
1. The VPN is setup and bound to eth1 and eth0 and works well internally
2. IPSec, GRE and PPTP rules have been declared on the router which port map to eth1
However I am still unable to setup a VPN connection to Linux Box I suspect something hasn't been done or I have setup my NATing or IPTables correctly on the linux box.

I have Linux installed on one machine with samba running and a second machine running XP. They are going through my router and I am using the same username/passwords for both machines and I have even gone to the point of allowing access to everyone for the share I created and the worgroup in samba is MSHOME just like my XP machine. When I view (or search) my workgroup computers my Linux machine shows up and so do the shares I created but when I try to open them I just get a message that permission is denied and I may not have permission to use this resource. I even tried setting access to the shared folder to 777 but still I can't open this share. Has anyone got any idea of why this is?
View 3 Replies View RelatedI will try to explain a bit first about my network typology: I have one cent os 5.5 machine with 2 nics - external one 86.x.x.122 and internal one with 2 IPs: 192.168.1.1 and 89.x.x.121. The ideea is that I have a public subnet (86.x.x.120/29) of IPs which are routable only through 86.x.x.122 so I have a webserver hosted on a different machine with the IP of 89.x.x.122 and GW 89.x.x.121 - everything works perfectly fine, except that I cannot access from the internal network 192.168.1.0 / 24 the so called DMZ (roughly) - the 89.x.x.122.
What really makes me crazy is that I setup the IPtables rules correctly because I can access the webserver from the outside world but I cannot accessit from the internal network...
what I'm missing - why the 192.168.1.0/24 cannot see the 89.x.x.122 machine... What IPtables rules should I add?
Can anyone here point me to a walk-through or discussion of how to use Webmin to set up port forwarding/NAT on a dual-NIC Centos 5.3 box? The layout will be simple:
Internet --- NIC1 [CentOS Box] NIC2 --- Switch to other PCs
We have a BUNCH of exposed services that are on special ports -- for example, to connect to one machine, you go in with [IP_Address]:12000, and to connect to another, [IP_Address]:12002, etc., etc. We're currently using OpenSuse 10.3 on this box, and YaST makes this criminally easy (you give it the incoming port number and the destination IP/port numbers and it just works). But OpenSuse 10.3 is nearing EOL, we're buying a new machine, and I'd like to use CentOS on the new one.
I've read the sparse Webmin documentation in their Wiki, and it leads one to believe that you simply insert a "NAT" rule. But there's obviously something they're leaving out. I *am* opening the ports in the firewall. But when I log in to [IP_Address]:port, it just times out. The port forwarding never occurs. The test in this case is SSH, and I know that SSHD is working properly because I can log into that machine just fine from another PC on the same internal subnet.
i am not able to port 8080 on my CentOS VPS server.I have followed all the instuctions as mentioned on iptables wiki page.Also I am able to telnet my ip address and port number, But can not access from browser.

I has used centos for all my servers but today i have problem with my router.
I install and configure my router/gateway as follows code...
at previous configuration (centos 4x) everything work well with those configuration but when i use centos 5.4
all my client cannot browse the Internet, its only work when i put the ISP dns (221.321.32.15)
i want my client use 192.168.0.1 as DNS.
I have centos on Microsoft Virtual PC 2007.
yesterday i updated my CentOS 5.4 with command "yum update" and today it won't to start.
Shows processor error and needs to be resetted.
How to solve this issue??
I recently configure a centos linux distro to use on the internet.my actual plan is to use it as a router to the internet for computers on my network. the system already has two lan cards which i have configured with their appropriate ip addresses. now with this initial configuration i believe i should be able to browse the internet, but my problem now is that i cant even though the lan card pointing to isp is correctly configured with the ips,gateway and dns from my isp. i cant even do a ping to the outside world.
I cant really pin point where the issue is coming from but i am guessing maybe my route are not well configured. i get ''unknown host google.com" message when i ping google.com and a ping to my gateway address gives '' Network is unreachable". i have been using this system before as my gateway, but only recently switched isp and i started having this issue when i reconfigure the system to my new isp settings. Now, on a windows system, all goes fine so i have been able to safely remove the fact that maybe it is from my isp from the picture. How do i resolve this?
I am confiuring DNS on CentOS 5.4 but unable to resolve.The configuration files and output of commands is given below.IP Address=192.168.0.66
/etc/resolv.conf
nameserver 192.168.0.66
nameserver 127.0.0.1

We installed CentOS 5 at our school and are attempting to get 2 simple DNS servers online. These are simple name resolution servers for our network. We installed the needed caching nameserver packages via Yum and all seems to be well, but for some reason when the server is online, it fails to resolve DNS records except when we direct the requests to its 127.0.0.1 (localhost) interface. As for the server specs, the DNS server is running on a Virtual Machine, and the ESXi server has 2 quad-core Xeon CPU's with 48 Gigs of RAM (in short.. hardware is adequate.)
Here's more details:
When the box boots up, we can confirm that the named service is running and it resolves DNS records when we direct queries to its localhost address:
[root@ns1 ~]# dig hotbot.com @localhost
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @localhost
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55510
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 0 .....
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @66.186.176.2
;; global options: printcmd
;; connection timed out; no servers could be reached
What would cause the Named service to not answer DNS queries from the physical IP but only from it's internal IP?

I have a HP notebook Compaq NX6110 with Cent OS 5.4 as a test PC. All equipment works correct except strange fact that notebook does not want to shutdown. When I try to shutdown it via graphical interface or CLI it only reboots. In system log there are no errors about ACPI or something like that. Who can give advice - is this bug in Cent OS 5.4 or something wrong with notebook?
P.S. I updated the BIOS with the last available version from HP
Following situation:
I'm trying to make a network-installation of my rootserver with CentOS 5.4 x86_64.
This server is hosted by 1and1 a company of the united internet group, which is a big player in europe.
The network environment of 1and1 is providing classless static routes via dhcp by using the dhcp option 121.
If i'm right anaconda does not support this dhcp option 121 and therefore does not "ask" for the routes.
Without the routes configured the traffic does not get through and the network installation fails.
An installation from fedora12 (anaconda 12.46) works without any problems.
Is there someone in the dev team that can patch or backport it?
It is really a problem that drives me crazy.

I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?
UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well
