Red Hat / Fedora :: Server All Of A Sudden Can't Access The Net?
Mar 8, 2011
which i have been using whilst setting it all up at my home, connecting to the internet without any problems until now.. All of a sudden it can't access the net, it can't ping my router.. but i am able to VNC to it accross the network, passing through said router. I have it set up with a static IP, and the router IP put in as DNS and gateway, when i tell it to get an IP vi DHCP, still the same problem.. I have no idea how to get this working, any ideas?? I am new with Linux, so please exlain what i need to do..
The only thing running on this server is basically Freeradius2, Coovachilli, Webmin and a virtual machine, which is an iRedOS Mail server.

I have a DNS server that's been working just fine up until now. I have a local domain, "galapagos.office" set up, with several subdomains on it. I've been able to get to all the subdomains just fine for the last couple weeks from several different machines.Now something weird's happening:
I CAN ping wiki.galapagos.office from a local machine
I CAN do an nslookup on wiki.galapagos.office from a local machine
I CAN see wiki.galapagos.office in a browser from a local machine
I CAN'T ping wiki.galapagos.office from the DNS server itself
I CAN'T do an nslookup on wiki.galapagos.office from the DNS server itself
I CAN'T see wiki.galapagos.office in a browser from the DNS server itself
And I COULD do all these things before. I don't know exactly when things went south because I almost never do anything from the DNS server itself.

I have been running two Ubuntu 10.10 servers for some time now. My main server is 10.111.1.65 and backup server is 10.111.66. The main server is to host my website and ssh remote access (Key auth). The backup server pulls via ssh key auth what is in my /var/www (among other folders) to the backup home dir (encrypted). For some reason today I checked the uptime and it was 7 hours on both servers. All my other computers on the same power supply have a uptime of over a month. For some reason I now cant access backup via ssh from main's key (I could before) and I can not get to the home dir, see below:
Code:
carlos@UbuntuSvrDell2400:~$ sh "Access-Your-Private-Data.desktop"
Access-Your-Private-Data.desktop: 1: [Desktop: not found

Have no idea what I am doing operating a server. Our programmer got a new job and I am the one who has to take it over. Everything was fine til yesterday. You see I made a control panel to easier update the site www(dot)discoverysound(dot)com
but yesterday when I went to update the site I got an error called fopen. I thought I fixed it (and boy did I ever) but now I cannot get to my site because it says Forbidden You don't have permission to access / on this server. Apache/2.0.47 (Unix) mod_ssl/2.0.47 OpenSSL/0.9.7a DAV/2 PHP/4.3.3RC4-dev Server at www(dot)discoverysound(dot)comPort 80.

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

Server details:
OS: Linux RedHat
DHCP: Static IP set to 192.168.1.101
sshd_config: Enabled for port 22 for ssh
Connected through wire to the Linksys router
Router:
Type: Linksys BEFW11S4
Port forwarding enabled for port 22 to IP 192.168.1.101
Client:
Windows 7
Interface: PuTTy
Host: 192.168.1.101 on port 22 through SSH
This always gives an error "connection timed out". SSH directly on the local Linux works fine.. Seems basic but had been struggling over this for past 3 hours to no avail so thought of posting it to the experts.

in my network, users has total access to their PCs, so theres a problem to filter (URL, ports,etc.) their virtual machines installed (they can assign self any IP, e.g.)
Id thought about use the MAC prefix in VMware VMs (00:0c:29:*), but i can only found a way through DHCP, and this isn't a good solution (they can assign a static IP to workaround...)
It will be better using firewall (iptables), but I don't found the way to add rules based in MACs with wildcards.

Since FC6, NFS became very finicky and seemingly causes servers to randomly denying mounts from some terminals but not others, with all exactly the same new FC installation and exactly the same hardware - crazy!. The only difference is hostnames of the terminals trying to mount NFS volumes on the server and I made sure that /etc/hosts on all terminals and servers contain each others ip addresses and hostnames. I always uninstall SELinux which is truly a huge pain in a corporate environment. Is there ANY way I can relax the NFS authentication on the server in order to make sure clients can mount volumes?
e.g. the following is encountered often, with sometimes crazy situations that clients can only mount nfs volum es from the server after I first boot the server and then ALL the terminals. It is painful as you might agree! Other way round, no go, client will not mount until server is booted and then client booted.
In this case I really prefer windows lackey security. It works. Never mind how crappy windows is, at least I don't have diabolical access problems on servers.. NFS used to be very nice about 6 years ago but truly sucks recently imo. /]# mount -o soft -t nfs nfsserver:/public /xfer mount.nfs: access denied by server while mounting nfsserver:/public

Want to access a printer attached to a windows 7 server. What I did was the following: 1. Installed samba-common, samba-client & samba-winbind. 2. Included Samba & Samba Client as Trusted Services in the Firewall with system-config-firewall. 3. SELinux is Disabled (in System Default Enforcing Mode). 4. Shared the printer in the Windows 7 server. Other Windows hosts in the LAN can print successfully.
In system-config-printer, I selected Add Printer -> Windows Printer via SAMBA -> Browse... The SMB Browser successfully found the Share and the Host, but won't show the printer. Am I missing something here? The samba wiki mentions that I also need to change some windows registries in this page: [URL].... Do I really need to do this? I don't want to needlessly mess with windows registry

I am having trouble getting my FC10 with tomcat visible to the outside world. first off i am somewhat new to linux. I am running vmware workstation to host my linux web server. i have my VMWare setup to use my second NIC solely. it is bridged and the tcp/ip is disable from the host. i can ping the ip address but cant access tomcat on port 8080 from the outside. i can hit it fine from inside fedora. i have configured my router (wrt54gs with DD-WRT firmware) for port forwarding. so basically i think that the problem is somewhere in between the host and the vmware configuring allowing the port to be forwarded through.

I am trying to make my home server accessible to the whole web. I have installed Nginx on my Fedora 15 64-bit Linux machine, and it works with localhost but it doesn't work online or allow other computers on the network to access it via the IP address. It keeps coming back with: Could not connect
I have port forwarding. I have even tried different ports but they all seem to be blocked. What could be wrong? I have a netgear router.

I configure named and stumble upon the following problem: named is serious about user rights, every config file named uses should be named:named. I set rights to named:named as follows, but they get changed to root:named when I restart named as root. The same thing happens with SELinux context. This results in access denied type errors.

I've been running a Samba server under RedHat 8 for five years without a hiccup. I want to cut over to a F10 box but cannot get shares accessible. smbclient attempts fail over NT password error. SELinux is disabled. Server is visible on the network. Users require no password access to shared data.
smb.conf follows:
# Samba config file created using SWAT
# from UNKNOWN (>)
# Date: 2009/06/12 14:15:15

I've recently installed CentOS 5, because I needed a good OS to run VMware Server. Just a heads up, I'm not very familiar with RH/CentOS distros, I usually use Arch Linux. My VMware install went fine, config is standard settings. Now I'm trying to access the VMware Infrastructure Web Access using port 8222 (http) and 8333 (https), but it's a no go. I'm connecting from another machine on the LAN, as the CentOS box is headless. I restarted the vmware services, and they seem to be launching fine. I don't know much about VMware though. I verified with netstat and ports 8222 and 8333 are listening.

I'm looking to set up a server with attached mass storage device and tape autoloader to run linux. It's set up under Windows at the moment. Goal is to have users, connecting from individual workstations and laptops, backup their data to the linux server. On their personal machine, some users run linux, some MacOS, some Windows. I plan to set up the 5 500 GB drives as RAID5. I understand that if setting up as software raid the format is "physical volume for RAID". Under this setup, will Windows users be able to read/write and function as expected? I can't assume only linux user access.

Like the title says. Suddenly, for no apparent reason KDE jumps to 100% cpu usage. I've tried tracking this down and it's frustrating. Sometimes I have to reboot 2 or 3 times to get it back down.

My Eclipse just stopped working all of sudden. This happened after I deleted some directories in my workspace, but I doubt that had anything to do with it.
I just get a small empty window when I try to run it. See attached png file.
