I am running Ubuntu Server 10.10. I have enabled UFW with the following rules:
Code:
To Action From
-- ------ ----
80/tcp ALLOW Anywhere
22 ALLOW Anywhere
8080/tcp ALLOW Anywhere
[Code]....
I am unable to ping from the server. What do I have to add to ping from the server? Do I need to Allow from 127.0.0.1 to Anywhere? I would like this server to be as secure as possible.
I am using an virtual machine. where I need to ping from one machine to another. earlier I was able to ping. But after going to google.com once, I cannot ping back to this machine.
But if I gave ping -I eth1 <IP> then I can ping.
I cannot install any package, so tell me solution which includes not installing any package.
I have multiple public ip addresses.My DSL modem blocks ping from a server behind the modem (nb6+4w) modem lan ip (gateway) is xxx.xxx.xxx.105the server is xxx.xxx.xxx.107If I DMZ this server it responds to pings.If i don't want to use DMZ, what service is ping using.I have set up virtual server 443 to this 107 ip as it's a SSL server
So I am trying to add some sites to my server, right now I have an active site at www2.site.tld. As a test, I copied [URL]to [URL], and changed only the line
ServerName www2.site.tld
to
ServerName what.site.tld
as well as renaming the lines for the log files appropriately then
which by everything I have read should result in what.site.tld being identical to www.site.tld. Instead, it flat-out does not resolve. Apache does create some blank log files in /var/www/
I really think that Ubuntu Server should by default have SMART monitoring enabled, and possibly prompt for a notification e-mail address (and SMTP server details if required) for SMART notifications to be sent to.
I have installed a ubuntu 9.10 server to use mostly as a fileserver. When I installed the server I set it up as DHCP and later on I have changed the /etc/network/interfaces file, the /etc/hosts file and the /etc/hostname file. I have the ip 192.168.1.100 set on the server and I can ping and SSH this address. But I can not ping my server by it's hostname enighet. I am setting up a NFS server and I would like to use my servers hostname when I do this. Why can I not ping my server by it's hostname? These are the 3 files I have changed...
Code: johan@enighet:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo
I have an IBM Bladecenter HS21 with 3 blade servers. All 3 blade servers were initially installed with RedHat Linux 4. I then installed ixMOS on one of the blade servers, and Mandriva Linux was also installed (over RedHat) automatically along with ixMOS.
Now, I have some network problems. The other 2 servers with RedHat can ping each other, but it appears that the server with ixMOS/Mandriva Linux is isolated, that is, I can't ping the other 2 servers from it, and I can't ping it from the other 2 servers.
Does anyone have any ideas on what is wrong and how I can solve this problem? One more thing, my installation of Mandriva Linux has no GUI, so I have to do everything using the command line interface.
I have set up UEC on a single machine 64 bit blade. I have followed the steps as per the documentation.I am using Managed NOVlan mode. I have installed the Karmic kola image. When I try to run the instance, I get an error "no resources available. Try --addressing private". When I try addressing private, an ip address 172.19.1.2 is assigned and the instance was running.
a) When trying to ping the ip, error displayed that the host is unreachableb) I am also unable to connect to ubuntu@172.19.1.2 using ssh. Error message is displayed that " No route to host".I have searched the forums but couldnt find any solutionPS: I suppose everyone is very busy. I see very limited responses to posts. Sharing your experience and expertise will be helpful for all and will reiterate the meaning of ubuntu
I am playing with openvpn, and I got stuck.I am using ubuntu server for openvpn server, which has 2 physical NICs, one is directly on internet and other is LAN, where few pcs are connected on.
I have configured DNS on ubuntu server 8.10 and it is working fine. There is one question I have though. Everytime I ping a LAN device by name I get the reply from the server with only the IP Address.
For clairification, I can ping. I have tried several IP addresses and 100% success rate. When I noticed the problem I was trying to run sudo apt-get update && apt-get upgrade After some time I noticed these error messages to start with

I tried to ping the adddress security.ubuntu.com from my Windows machine to verify that I could connect and was surprised when I could. I then pinged the address 91.189.92.167 which is what my windows machine resolved the name as and it went though.
My thoughts on this are that when my Ubuntu Router came up, for some reason it did not incorporate the ISP's DHCP servers into the ip address it obtained. Sadly I know to view ALL IP infomation in windows via ipconfig /all command but I do not know what this is in the *nix world. need commands that I can use to check and troubleshoot this apparently DHCP issue so I Can start to update my server and expand on its services?
We've recently created 3 new RHEL5 servers and added them to the existing workgroup which all our other 7 RHEL4 servers run on. (All servers have been added into DNS). We seem to be having a few issues pinging 3 of the RHEL5 servers.
Below is an example of our ping tests: WinsSrv1: Can ping all but RHELSrv1 WinsSrv2: Can ping all REHL Servers WinsSrv3: Can ping all but RHELSrv2 WinsSrv4: Can ping all but RHELSrv2 & RHELSrv4 WinsSrv5: Can ping all RHEL Servers
There is no real pattern as to what server we can ping. We can ping all RHEL4 servers with no issues. All REHL5 servers can ping themselves with no issues.
I have been logging into a server remotely and trying to set up a mailing list on it. The server is the newest version of ubuntu server: uname -a: Linux Themis 2.6.28-11-server #42-Ubuntu SMP Fri Apr 17 02:48:10 UTC 2009 i686 GNU/Linux.I noticed I could not download packages with apt-get or ping domain names, and I can't even ping 127.0.0.1.And do you think there is something wrong with the network card?
Not sure if this post belongs here, but here it is.
Host: Win server 2003 Guest: Ubuntu server
Host: IS able to ping guest. Firewall is OFF. NOT able to access guest (which is a web-server) at browser. Guest: NOT able to ping host. Running a web server, you can check the website: (pegajosa.com) is running under that virtual Linux server.
Problem: guest needs to access host's sql database and/or any resources.
I have a DHCP server that I only mildly trust, but its nice because it is an eBox server (I use it for DNS, DHCP, and smtp relay for my internals). I want it to issue all addresses (simply because I like the way it displays its leases in the WebUI's dashboard), but I want a fail-safe too. I have another server that is strictly an Ubuntu Hardy server (I use it for openVPN and nothing else) so I would like it as my backup dhcp server. I figure I'll install all the dhcp stuff on it and just stop the service (to include a sudo crontab @reboot script to stop it when rebooted).
And simple use a sudo crontab script to ping the eBox every 5 minutes to make sure its live, and if not then start the dhcp server. My questions: If I put the entry in my sudo crontab will the script execute even if no session is currently running (its obviously a server so won't have anyone logged in except for administration)? Also since it is in the root crontab it will be able to start the init.d service without having to sudo it right (IE the script only needs to say "/etc/init.d/dhcp3-server start" not "sudo /etc/init.d/dhcp3-server start")?
I have an embedded server running Ubuntu which is on a network with a lot of wireless AP's. The AP's doesn't support SNMP or anything else, so I monitor if they are up or down by simply pinging them continuously.
My question is if there is anything I could install on the server that could provide me with a webpage where I could see the ping time to the AP's? So it just shows a list of the IP's I have told it to ping, and what their latest response time is. This is what I basically need, but if it were more advanced than that, and could give warnings if ping time were to high etc.
I have two linux servers, I tried to ping from one linux box to another and vice versa but error message is "connect: Network is unreachable" Where as If I tried from windows machine I am getting the reply from both the servers. C:Documents and Settings>ping bnkprod

I had configured openvpn in my fedora 7. every thing seems ok. created all server,client certificates. and at client laptop i am using win xp. i installed vpn at client laptop n vpn is connected and client got the ip address of the range which i had defined in server.conf.
Now the problem is this that client vpn is connected and got the ip even than client not able to ping local network of my office.guys ur support n guidance needed.
in my office i had configured openvpn on fedora 7, no problem in server side. my network is like this.Office Lan - 192.168.1.0/24vpn machine - 192.168.1.141/24 - (done port forwarding at router)now i had some clients who wants to access office lan from outside so i installed client certificates on their laptop whose OS is XP so my XP clients r easily le to connect to vpn from outside n can access the office lan i.e 192.168.1.0,but problems comes with the VISTA clients who r having VISTA can connect to vpn machine n they get the ip from linux vpn machine but VISTA client cant ping my office network i.e 192.168.1.0/24
I am testing with Suse Linux Enterprise Server 10 in a VMWare environment. I've installed two SLES10 servers, named sles1 and sles2. I can't get the two servers to communicate, even a simple ping won't work. The "Network Adapter" in VMWare is set to "bridged", a setting which has worked fine when installing WinXP in VMWare and connecting to the Internet. I have configured the Network Settings as follows:
Hostname/DNS tab: -Hostname: sles1 -Domain Name: local -Name server: blank
Routing tab: -Default Gateway: 192.168.0.1 (= my router connected to the Internet) SLES2: same as sles1, with IP 192.168.0.22 and Hostname sles2
With these network settings, the two servers seem totally unable to communciate. -When I ping sles2 from sles1, I always get the error message: connect: Network is unreachable -Whatever way I ping, either ping sles2, ping sles2.local, ping 192.168.0.22, whatever, the error message is always the same. -Even if I ping sles1 from sles1 (= "pinging myself"), I get the same error message. -Only if I ping localhost, I get a proper ping result.
I have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.
I'm trying to enable the rewrite module in apache, to enabled the module I followed the last entry in the fist page this thread:[URL]...When I restart the apache all works fine, so I supose it's enabled

This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.
I have a debian server installed with a static ip. Now i am able to ping my ip, but when i try to configure a domain name with the nameserver as my ip, i am not able to ping the domain name
I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:
Code:
Ping by IP - the responses come VERY quickly one after the other:
