  • Are there any tests I can run on a network to simulate 100 heavy network users?

    - by marc.gayle
    I will be hosting a Ruby on Rails workshop at a small hotel in the near future, and while they have 'Wifi' everywhere on the property, and the property normally hosts 150 - 300 people, I am not 100% confident that they have hosted 150 tech people that tend to have heavy web surfing habits/needs. Their tech department is also 1 or 2 guys. Are there any automated tests I can download and run from my laptop, on the network, that would simulate 100 'heavy users' on the network at the same time? Their broadband pipe is a 15mbps cable connection. Would that suffice for the general surfing needs of 100 - 150 techies? I know all it takes is 1 or 2 bit torrenters to kill the entire network, but assuming we can at the very least block those ports or encourage the attendees not to file share on the network, would that speed suffice for general surfing needs? What are good resources online that would allow me to quickly get up to speed on the IT related issues, so that I can ask their sysadmins the right questions? Edit: Note that I am fairly technical, so assume I can get up to speed quickly even with technical manuals, etc.

  • (manually configured) kernel update leaves wireless in a mess

    - by Mala
    I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so. The problem is "solved" by booting into the older kernel. The relevant lspci entry is 02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection I'm pretty sure I have the correct drivers enabled in the kernel Device Drivers ---> Network device support ---> Wireless LAN (IEEE 802.11) ---> <*> Intel Wireless Wifi [*] Enable LED support in iwlagn and iwl3945 drivers [*] Enable Spectrum Measurement in iwlagn driver [*] Enable full debugging output in iwlagn and iwl3945 drivers <*> Intel Wireless WiFi Next Gen AGN (iwlagn) [*] Intel Wireless WiFi 4965AGN [*] Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)? Thanks Mala

  • Comprehensive solution for managing patches, event viewing, change management, inventory, etc

    - by Holocryptic
    I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

  • Apache - virtualhost - works only one

    - by user1811829
    I need a couple of virtualhosts on my local dev machine. Unfortunately it needs to be windows. httpd-vhost.conf <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs" ServerName localhost </VirtualHost> <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs/manadom.local/public" ServerName manadom.local ErrorLog "logs/manadom.local-error.log" CustomLog "logs/manadom.local-access.log" combined </VirtualHost> <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs/galeriabiznesu" ServerName gb.loc ErrorLog "logs/gb.loc-error.log" CustomLog "logs/gb.loc-access.log" combined </VirtualHost> And hosts file: 127.0.0.1 localhost 127.0.0.1 manadom.local 127.0.0.1 gb.loc The problem is: localhost points to C:/xampp/htdocs/manadom.local/public manadom.local points to C:/xampp/htdocs/manadom.local/public too gb.loc points to C:/xampp/htdocs/manadom.local/public I can't idea what's wrong? Please help me, i'm not an admin but i read about it lot and i don't know what possibly i can do wrong.

  • SSH Private Key Not Working in Some Directories

    - by uesp
    I have a strange issue where SSH won't properly connect with a private-key if the key file is in certain directories. I've setup the keys on a set of servers and the following command ssh -i /root/privatekey [email protected] works fine and I login to the given host without getting prompted by a password, but this command: ssh -i /etc/keyfiles/privatekey [email protected] gives me a password prompt. I've narrowed it down that this behavior occurs in only some sub-directories of /etc/. For example /etc/httpd1/ gives me a password prompt but /etc/httpd/ does not. What I've checked so far: All private key files used are identical (copied from the original file). The private key file and directories used have identical permissions. No relevant error messages in the server/client logs. No interesting debug messages from ssh -v (it just seems to skip the key file). It happens with connecting to different hosts. After more testing it is not the actual directory name. For example: mkdir /etc/test cp /root/privatekey /etc/test ssh -i /etc/test/privatekey [email protected] # Results in password prompt cp /root/privatekey /etc/httpd # Existing directory ls -ald test httpd # drwxr-xr-x 4 root root 4096 Mar 5 18:25 httpd # drwxr-xr-x 2 root root 4096 Mar 5 18:43 test ssh -i /etc/httpd/privatekey [email protected] # Results in *no* prompt rm -r test cp -R /etc/httpd /etc/test ssh -i /etc/test/privatekey [email protected] # Results in *no* prompt` I'm sure its just something simple I've overlooked but I'm at a loss.

  • "Server Unavailable" and removed permissions on .NET sites after Windows Update

    - by tags2k
    Our company has five almost identical Windows 2003 servers with the same host, and all but one performed an automatic Windows Update last night without issue. The one that had problems, of course, was the one which hosts the majority of our sites. What the update appeared to do was cause the NETWORK user to stop having access to the .NET Framework 2.0 files, as the event log was complaining about not being able to open System.Web. This resulted in every .NET site on the server returning "Server Unavailable" as the App Domains failed to be initialise. I ran aspnet_regiis which didn't appear to fix the problem, so I ran FileMon which revealed that nobody but the Administrators group had access to any files in any of the website folders! After resetting the permissions, things appear to be fine. I was wondering if anyone had an idea of what could have caused this to go wrong? As I say, the four other servers updated without a problem. Are there any known issues involved with any of the following updates? My major suspect at the moment is the 3.5 update as all of the sites on the server are running in 3.5. Windows Server 2003 Update Rollup for ActiveX Killbits for Windows Server 2003 (KB960715) Windows Server 2003 Security Update for Internet Explorer 7 for Windows Server 2003 (KB960714) Windows Server 2003 Microsoft .NET Framework 3.5 Family Update (KB959209) x86 Windows Server 2003 Security Update for Windows Server 2003 (KB958687) Thanks for any light you can shed on this.

  • Is it possible to add/register an MIB for the Windows built-in SNMP service?

    - by michielvoo
    I need to build monitoring into an existing .NET application. I will use SNMP to send the application's status to the Windows SNMP service. I have used a .NET library to create the SNMP SET request according to the MIB that I have been provided with, and with the correct community. My code now sends multiple 'variables' in a SET request, for example: Id: ".1.3.6.1.4.1.43607.1.1.1.1.1" (ObjectIdentifier) Data: 42 (Integer32) On my machine I have enabled the SNMP service, configured a community with READ/WRITE permissions, and added localhost to the list of hosts to accept requests from. When I send the SET request I get a response, but it has error status 17 which, according to MSDN means SNMP_ERRORSTATUS_NOTWRITABLE. The response also has error index set to 8, which is the number of variables I send. If I send 7 variables, the error index is set to 7. I think the problem is that the Windows SNMP service is preconfigured to only accept SET requests for a fixed set of MIBs. How can I get the Windows SNMP service to 'accept' my custom MIB SET request? Edit: I downloaded and installed the Windows Server 2003 Resource Kit and tried to 'compile' the MIB file with mibcc.exe ("SNMP MIB Compiler") but I have not been able to compile any MIB files (even the most basic ones like SNMPv2-SMI.mib).

  • Can a folder on a NAS be made available as a physical drive in VMWare?

    - by asbjornu
    We are currently in the process of moving from a single web server to two load balanced web servers and are facing some challenges we don't quite know how to fix. One of these is that the current single server hosts applications that write stuff to disk. The applications running on the server expects that when something is written to disk it later will in fact exist, so it's important that this premise is fulfilled with the dual server architecture as well. The dual server setup is a couple of VMWare instances with Windows Server 2008 R2 as the guest operating system. Out of the box, these instances does not share any kind of file system, so just moving the applications over would make them break since one instance would write something to the file system that doesn't exist on the other. Thus we need to share a file system between the two virtual servers. Our host has proposed to create a network share on a SAN and map this share individually on each virtual machine. This doesn't work too well due to NTFS permissions, etc., because the share needs to be accessed by several independent web applications that won't even be in the same application pool. The only solution that kind of works is to hard code an "identity" for each web application into its web.config file, but this means password in clear text which doesn't sit well with me. Since the servers are virtual, I'm thinknig: Wouldn't it be possible to make a NAS area available as a physical disk in the gues operating system somehow? Since VMWare has full control of the virtual hardware, you'd think it would be able to "fake" a local hard drive in the virtual machine that in reality is a folder on a NAS, but so far I haven't found anything that states how and if this is possible. So I have to ask the wonderful Server Fault community: Can a folder on a NAS be made available as a physical drive (typical D:) in both of the virtual machines?

  • Can't ping guest OS from Windows XP SP3 host running VIC.

    - by Vittal
    Hi, I am running VMware ESX Server 3i Version 3.5.0 and accessing this server using VMware Infrastructure Client Version 2.5.0 on a Windows XP SP3 machine. I have enabled the Microsoft TCP/IP version 6 stack and assigned an IPv6 address (using the netsh command) to the network adapter. The guest OS'es running on ESX Server (includes Win7, W2K8, WinXP) also have IPv6 addresses enabled on their adapters. The adapters are configured to be in VM Network (Bridged mode) and hence have connectivity to the Internet. The VMs are able to ping each other using IPv6 addresses and are also able to ping a physical Win7 machine using IPv6 addresses. However, the Windows XP SP3 machine on which the Client is running is not able to ping any hosts running on ESX Server while the VMs are able to ping this host. Whenever I try to ping from WXP box I get the "Invalid source route specified." error. The WinXP machine is not able to ping the Win7 physical machine too (the same error as above is thrown). Can someone help me understand why I am receiving this error and what I need to do to resolve this error? Thanks, Vittal

  • New Static Website with Hosted DNS alternating 502, 503 and Page Does Not Exist Errors

    - by Dave
    This has become an increasingly frustrating ordeal. I'm mostly a web developer, so forgive me if I am using improper terminology here. I have a client that had purchased a domain at JustHost. We built him a website and have it on our own server space. Now, I'm mostly used to dealing with godaddy and it is simple enough to manage dns records and point the A record to our server IP, where Apache on our end deals with the domains via name-based virtual hosts. But for some reason, in setting this up with JustHost, when attempting to go to the domain name, I either get a 502 or 503 error or "webpage does not exist". Now, I know that the basic functionality of the webpage must be working because I can access the the index etc straight through my servers www data (IE [server-ip]/website_folder). I was on the phone with technical support for over three hours yesterday with justhost and the best I could get was "That's really weird..." I've checked my logs and there doesn't seem to be anything coming through to my end. Does anybody have an idea of whats going on here? I would love for it to be a problem on my end, because justhost doesn't seem capable of helping further. Any help is greatly appreciated, thanks. I forgot to mention that we have several other sites up and running and completely accessible.

  • Why would one of my servers stop being able to access other servers by FQDN?

    - by Newlyn Erratt
    I have a number of servers on our local network and our debian server has suddenly stopped being able to access the other servers via their FQDN. Initial symptom was inability to login with Active Directory accounts. On further inspection, this machine, porkbelly, was unable to access our other servers (e.g. bacon and albert) via their FQDN. That is, they can ping albert by running ping albert but not by running ping albert.domain.local though when running ping albert it will be expanded to albert.domain.local. The server is still accessible from other servers via both porkbelly and porkbelly.domain.local. Upon examination of hosts information and running hostname its hostname and FQDN are correct. The resolv.conf appears correct. It contains: domain domain.local search domain.local nameserver 192.168.0.xxx (the nameserver) The dns server is also our Windows AD server. I'm not even sure where to go from here or why dns seems to be partially working though I don't have much experience. Where should I go from here? What might be causing this issue where machines are visible via their hostname but not their FQDN?

  • Cheap Solution for Routing a Toll Free Number to a Standard POTS Number

    - by VxJasonxV
    I do some technical work for an Internet Radio Show/Podcast, and need to fix something that has been broken for a while. The hosts have a Skype-In number to take listener calls, and for convenience sake, I bought and paid for a toll free number for a period of time. I used to use Asterlink for routing calls, but they folded and sent my number to OneBox, but they're ridiculously expensive by comparison. I'm looking for a cheap solution for this one simple task. Forward toll free calls to a skype-in number. The definition of cheap is as cheap or cheaper than Asterlink was. I paid something like $2 a month, and then the termination/call rate, which was a fraction of a sent for termination, and only whole cents after some serious time on the call. A $20 preload lasted me months at a time. I don't want to be upsold too, I want a simple web based management screen (CDR/stats are fun!), and obviously, it needs to be reliable. What vendors out there are you a fan of that solves this need?

  • How is it possible that I can do a host lookup but not a curl?

  • What is the recommended glusterFS configuration for a growing website?

    - by montana
    Hello, I have a website that is tracking towards 50 million hits per day average, and within the next 3 months should be over 100 million hits per day. We are trying to use GlusterFS v 3.0.0 (with latest patches as of 1-17-2010) Currently, we've just upgraded to a load balancer environment that has 3 physical hosts with 6 Xen-Server 5.5u1 VM's (2 on each host) to serve webpage traffic. Each machine has 6 Raid-6 local storage drives (7200RPM-SATA). The old machine we came from had 1 mirrored SAS 10k drive. We also set up glusterFS currently with 3 bricks, one on each host, and it is serving the 6 VM's as clients. In testing, everything seemed fine. However when we went to production, it seemed that there just wasn't enough I/O's available to serve traffic even upwards of 15mil hits. Weeks prior, our old server was able to handle traffic, maxed out, at 20mil. Is there any recommended configurations for such an application, or things to be aware of that isn't apparent with their documentation at gluster.org for a site our size?

  • Keepalived for more than 20 virtual addresses

    - by cvaldemar
    I have set up keepalived on two Debian machines for high availability, but I've run into the maximum number of virtual IP's I can assign to my vrrp_instance. How would I go about configuring and failing over 20+ virtual IP's? This is the, very simple, setup: LB01: 10.200.85.1 LB02: 10.200.85.2 Virtual IPs: 10.200.85.100 - 10.200.85.200 Each machine is also running Apache (later Nginx) binding on the virtual IPs for SSL client certificate termination and proxying to backend webservers. The reason I need so many VIP's is the inability to use VirtualHost on HTTPS. This is my keepalived.conf: vrrp_script chk_apache2 { script "killall -0 apache2" interval 2 weight 2 } vrrp_instance VI_1 { interface eth0 state MASTER virtual_router_id 51 priority 101 virtual_ipaddress { 10.200.85.100 . . all the way to . 10.200.85.200 } An identical configuration is on the BACKUP machine, and it's working fine, but only up to the 20th IP. I have found a HOWTO discussing this problem. Basically, they suggest having just one VIP and routing all traffic "via" this one IP, and "all will be well". Is this a good approach? I'm running pfSense firewalls in front of the machines. Quote from the above link: ip route add $VNET/N via $VIP or route add $VNET netmask w.x.y.z gw $VIP Thanks in advance. EDIT: @David Schwartz said it would make sense to add a route, so I tried adding a static route to the pfSense firewall, but that didn't work as I expected it would. pfSense route: Interface: LAN Destination network: 10.200.85.200/32 (virtual IP) Gateway: 10.200.85.100 (floating virtual IP) Description: Route to VIP .100 I also made sure I had packet forwarding enabled on my hosts: $ cat /etc/sysctl.conf net.ipv4.ip_forward=1 net.ipv4.ip_nonlocal_bind=1 Am I doing this wrong? I also removed all VIPs from the keepalived.conf so it only fails over 10.200.85.100.

  • Why the VPN Network Shake-Up?

    - by Brent Arias
    I can RDP to another machine on my home network, only if I'm not also hooked up to my employer's VPN with the Cisco VPN client. Indeed, I can't even ping the other machine by name in this mode, because ICMP suddenly thinks that ( ping myMachine ) now means ( ping myMachine.myEmployer.com ). Of course there is no machine by that latter name, and so it fails. Even weirder, once I disconnect from the VPN I can again ping myMachine successfully, but ICMP reports the machine by its MAC address instead of its IP address. I don't think I've ever seen ping identify another machine by its MAC address. So two questions: How can I access via RDP/ping the other machine BY NAME on my local network while also connected to the VPN? Why is ping identifying a MAC address for the machine on my home network, instead of an IP address? And how can I change this so that an IP address is reported instead? For question #1, I can indeed access the other machine on my home network by IP address. I suspect if I put the name-IP pair into my HOSTS file, then I would be able to access it even when connected to the VPN. But I wonder if there is another (more elegant) solution?

  • Simplest DNS solution for remote offices

    - by dunxd
    I look after a bunch of remote offices that connect via VPN - a Cisco ASA 5505 in each office acts as Firewall and VPN end point. Beyond that we keep things as simple as possible in the offices to minimise the support burden. We don't have any kind of server except in offices large enough to justify having someone dedicated to IT. Basically there is the ASA, some computers, a network printer and a switch. One of the problems I am seeing in a lot of offices is that DNS requests looking up hosts inside our network often fail - I'm assuming timeouts due to the offices internet connection (they are all in developing world countries) having some sub-optimal qualities (e.g. high latency caused by VSAT segments, or packet loss. The obvious solution to this is to have some sort of local DNS service that can serve local requests - so I think it would need to do zone transfers from our Microsoft Windows 2008 R2 DNS servers at HQ. However, simply installing Windows Servers in each office is both expensive, and creates a support burden. This got me thinking about pfsense/m0n0wall on embedded devices - those can act as a DNS server, and could be configured at HQ and sent out as just something that needs to be plugged into the network and can then be forgotten about by the staff locally. Maybe there are some alternatives to the ASA 5505 that include some DNS functionality. Has anyone here dealt with the problem, either using some kind of embedded device, or found some other solution? Any gotchas or reasons to avoid what I have suggested?

  • E-mail duplication problem

    - by Gavin Osborn
    I have taken out a hosting agreement with a well respected hosting provider for a couple of internet facing servers. We have deployed several applications to these servers which send various e-mails back to us for reporting purposes. Context: Each server runs Windows Server 2003 R2 with the IIS 6.0 SMTP service installed. Each application is configured to use the local instance of IIS to send e-mails. The external IP address of each server is mapped to a particular domain eg: server1.mydomain.com server2.mydomain.com These e-mails are sent from a company domain name and not the domain name of the hosted servers (eg: [email protected]) Symptoms: A small number (<1%) of e-mails sent from these applications appear to be duplicated. These are exact duplicate in terms of both content and message headers. The Fix: I contacted my hosting provider and they told me this was a common problem & instructed me to: Change the HELO response of your mail server service to a FQDN (server1.mydomain.com && server2.mydomain.com) Create a DNS A record that resolves the FQDN of your mail server to the primary IP address of your sending mail server. Create a PTR record that resolves your primary IP address back to your mail server's FQDN In the sending domain's (mycompanydomain.com) DNS zone file, add the appropriate SPF record for your hosted servers. eg: v=spf1 a mx include:mydomain -all The Problem Continues: I made all of the changes as prescribed above, I was a little hesitant because these steps seemed to suggest they were more for stopping your messages getting blocked than they were for stopping them from being duplicated - but I am certainly no expert in these matters. It has been 5 days since I applied this fix and the problem still persists. I am certain that these problems are not a bug in the software because they are 4 different applications installed on 2 different servers, all of whom are exhibiting this strange behaviour. This behaviour has also not been seen in our UAT environment. Were my hosts correct to suggest this fix? If not, does anyone know what could be the cause of this problem? Many Thanks

  • WRT54GL Tomato Router in Client wireless mode to an iPhone Personal Hotspot

    - by Gordo
    I am trying to connect a router with Tomato firmware to an iPhone 4. The goal is to connect to the Personal Hotspot in Client Wireless mode. This should allow wired and wireless users to connect to the router rather then the iPhone. In theory this should be possible but I am having difficulty. Router Linksys WRT54GL Tomato 1.28.1816 firmware iPhone iPhone 4 iOS 5.1 (9B176) Carrier Rogers Wireless Personal Hotspot works with other devices, wifi/bluetooth/usb iPhone Personal Hotspot settings Mode: B/G Security: WPA or WPA2 Personal Encryption: AES Router IP: 172.20.10.1 Subnet: 172.20.10.0 Min IP: 172.20.10.2 Max IP: 172.20.10.14 maximum number of wireless tethered hosts is 5 I have followed the directions here: http://www.wi-fiplanet.com/tutorials/article.php/3810281 Ensured that the router subnet does not 'collide' with the iPhone subnet. Here is the configuration of the Tomato 'Basic - Network - Wireless' section: http://i.stack.imgur.com/pbmTB.png I have tried several variations of this configuration, but nothing seems to work. NOTE: I have successfully connected to my own wifi network in Wireless Client mode, so I am confident that there are no bad cables or other hardware issues. I would prefer to use Tomato, but DD-WRT maybe my only other option. Thanks!

  • Multiple munin-nodes per machine

    - by Alexander T
    I'm collecting statistics remotely through JMX. The munin JMX plugin allows you to select an URL to connect to when aggregating statistics. This allows me to collect statistics from hosts which do not actually have munin-node installed. I find this a desirable property for some systems where I am hindered to install munin-node. How I work today is that if i want to collect JMX stats from machine A without munin-node, I install munin-node on machine B. Machine B then collects data from A via JMX, and reports it to munin-server, which runs on machine C. This setup requires multiple B-type machines: one per C-type machine. I would like to avoid this and instead use only one B-type machine to collect the data from all A-type machines and reports it to the only munin-server (C-type machine). As far as I understand this requires running multiple munin-nodes on B or in some other way report to munin-server that the B-type machine is reporting data from multiple sources. Is this possible? Thank you.

  • fwbuilder/iptables manually scripted + autogenerated rules at startup?

    - by Jakobud
    Fedora 11 Our previous IT-guy setup iptable rules on our firewall in a way that is confusing me and he didn't document any of it. I was hoping someone could help me make some sense of it. The iptables service is obviously starting at startup, but the /etc/sysconfig/iptables file was untouched (default values). I found in /etc/rc.local he was doing this: # We have multiple ISP connections on our network. # The following is about 50+ rules to route incoming and outgoing # information. For example, certain internal hosts are specified here # to use ISP A connection while everyone else on the network uses # ISP B connection when access the internet. ip rule add from 99.99.99.99 table Whatever_0 ip rule add from 99.99.99.98 table Whatever_0 ip rule add from 99.99.99.97 table Whatever_0 ip rule add from 99.99.99.96 table Whatever_0 ip rule add from 99.99.99.95 table Whatever_0 ip rule add from 192.168.1.103 table ISB_A ip rule add from 192.168.1.105 table ISB_A ip route add 192.168.0.0/24 dev eth0 table ISB_B # etc... and then near the end of the file, AFTER all the ip rules he just declared, he has this: /root/fw/firewall-rules.fw He's executing the firewall rules file that was auto-generated by fwbuilder. Some questions Why is he declaring all these ip rules in rc.local instead of declaring them in fwbuilder like all the other rules? Any advantage or necessity to this? Or is this just a poorly organized way to implement firewall rules? Why is he declaring ip rules BEFORE executing the fwbuilder script? I would assume that one of the first things the fwbuilder script does it get rid of any existing rules before declaring all the new ones. Am I wrong about this? If that was the case, the fwbuilder script would basically just delete all the ip rules that were defined in rc.local. Does this make any sense? Why is he executing all this stuff at startup in rc.local instead of just using iptables-save to keep the firewall settings at /etc/sysconfig/iptables that will get implemented at runtime?

  • Host name change breaking http? Fedora

    - by Dave
    OK so I have been messing around on my development server. It has been a while since I have had my head in linux and I suspect I have broken something. I have SSH running and that is working fine. I also have HTTP and I had FTP running also. Earlier today I decided I wanted to rename the machine so I updated the /etc/hosts file and /etc/sysconfig/network. I also changed the server name in the httpd.conf. I rebooted the machine and reconnected to SSH fine. Later I was messing around with the FTP service (trying to tighten up the user security) and when i tried to connect remotely to FTP no joy, it said cannot connect. I thought that was weird but had planned to remove ftp as we will be using github so removed ftp and moved on. Then I tried to connect to the website but major fail. even connecting to the IP address is failing. I used lynx to connect to the localhost and there was my site so something going on at server level. I thought maybe something up with iptables but I have not changed them but tried adding http but still no joy. I have a - Fedora release 17 (Beefy Miracle) NAME=Fedora VERSION="17 (Beefy Miracle)" ID=fedora VERSION_ID=17 PRETTY_NAME="Fedora 17 (Beefy Miracle)" ANSI_COLOR="0;34" CPE_NAME="cpe:/o:fedoraproject:fedora:17" Fedora release 17 (Beefy Miracle) Fedora release 17 (Beefy Miracle) Linux version 3.3.4-5.fc17.x86_64 ([email protected]) (gcc version 4.7.0 20120504 (Red Hat 4.7.0-4) (GCC) ) #1 SMP Mon May 7 17:29:34 UTC 2012 This is my iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT icmp -- anywhere anywhere ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh REJECT all -- anywhere anywhere reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) target prot opt source destination REJECT all -- anywhere anywhere reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) target prot opt source destination Like I say I can use SSH no issue but http although running is a no go from a remote computer. Any ideas?

  • My DNS works! But, what is the simplest way to add something to it?

    - by Alex
    This is my current DNS example.com.db zone file. I followed a tutorial. It works, because when I point to this DNS from another server via resolve.conf, it will actually forward me to the right IP when I do "ping example.com". ; ; BIND data file for example.com ; $TTL 604800 @ IN SOA example.com. info.example.com. ( 2007011501 ; Serial 7200 ; Refresh 120 ; Retry 2419200 ; Expire 604800) ; Default TTL ; @ IN NS ns1.example.com. @ IN NS ns2.example.com. example.com. IN MX 10 mail.example.com. example.com. IN A 192.168.254.1 www IN CNAME example.com. mail IN A 192.168.254.1 ftp IN CNAME example.com. example.com. IN TXT "v=spf1 ip4:192.168.254.1 a mx ~all" mail IN TXT "v=spf1 a -all" Right now, ping example.com....goes to 192.168.254.1. That's great!!! it works! My question is--how can I add something do this file so that when my other servers: ping dbserver1....goes to 44.245.66.222 ping cacheserver1 ....goes to 38.221.44.555 I want to use it like a universal hosts file for my machines.
