• how do I set up a virtual host (it's not working, and I've done everything right)

  - by piratepartypumpkin

  My router redirects port 80 to port 8080. My router works fine and my domain name is routed properly. This is my virtual hosts file: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /home/admins/lampstack-5.3.16-0/apps/wordpress ServerName example.com ServerAlias www.example.com </VirtualHost> I can access my website by entering "mywebsite.com:8080" but I cannot access it by entering "mywebsite.com" For further information, this is a part of my httpd.conf: Listen 8080 Servername localhost:8080 DocumentRoot "/home/admins/lampstack-5.3.16-0/apache2/htdocs <Directory /> Options FollowSymLinks AllowOverride None Order deny, allow deny from all </Directory> <Directory "/home/admins/lampstack-5.3.16-0/apache2/htdocs"> Options FollowSymLinks AllowOverride None Order allow, deny allow from all </Directory>

• Why does a redirect from a local IP address assume localhost?

  - by Jeremy

  I am developing a web application on my desktop and it is running on port 80. I am able to access the application from my laptop connected to the LAN by entering my desktop's LAN IP address 192.168.1.8. Now, my application sends a redirect after login, but my laptop assumes the final address is localhost/login. If I manually type in the IP address and URI for any page, it shows that I am logged in, so it works as expected. So, why does the redirect assume localhost? Both of my machines are linux-based. The laptop being Chrome OS. I am running nginx which proxies non-static file requests to jetty on port 8080.

• Do two portforward rules translate to "and"?

  - by blsub6

  I just set up an Exchange server to replace my DeskNow mail server. I want to start testing my internet mail exchange of my Exchange server. I can only set the MX records on my DNS up to my one external IP address so I was thinking that I could set up a firewall rule on my internet-facing firewall that port forwarded the smtp packets to two different servers. My question is: If I do that, will that mean that the smtp packets will be forwarded to just the first internal IP on the list? Or does it mean that the packet will be cloned and sent to both IPs?

• How do I configure additional phone lines asterisk/trixbox?

  - by Matt

  I have a 4 port Digium card in there, and have 4 lines running smoothly. Now, we added ANOTHER 4 port card and have 4 more analog lines coming into the Trixbox server. It still runs the 4 fine, but what do I need to do to add the additional 4 phone numbers/lines? I want it to act exactly as before, there's nothing special about the new lines. We just need more lines so that when we have 4 out of state customers call, we can have 4 more call and not get the busy signal. Trixbox CE 2.8

• Help, my CentOS servers keep going down , No route to host after a random uptime

  - by user249071

  Hello , I have a couple of Centos linux servers, that have a very simple task, they run nginx + fastcgi for php , and some NFS mounts between them, readonly They have some RPC commands to start some downloading processes with wget, nothing fancy , from a main server, but their behavior is very unstable, they simply go down, we tried to monitor ram , processor usage, even network connections, they don't load up so much, max network connections up to... 250 max, 15% processor usage and memory , well, doesn't even fill up, 2.5GB from 8GB max , I have no ideea why can a linux server go down like that, they aren't even public servers, no domain names installed no public serving, for sites. The only thing that I've discovered was that if i didn't restart the network service every couple of hours or so... the servers were becoming very slow, starting apps very slow, but not repoting a high usage of resources...Maybe Centos doesn't free the timeout connections, or something like that...It's based on Red Hat right? I'm not a linux expert , but I'm sure that there are a few guys out there that can easily have an answer to this , or even have some leads to what i can do ... I haven't installed snort, or other things to view if we have some DOS attacks, still the scheduled script that restarts the network each hour should put the system back online, and it doesn't.... Thank you in advance

• Is SATA bandwith per Port or per Controller?

  - by instanceofTom

  I always assumed that it was per Controller channel, and that If I have 4xSATA 3.0Gb/s ports on my Motherboard then I should have a potential 12.0Gb/s of bandwith. However, after doing some searching I found conflicting information suggesting that if I had 4xSATA drives connected to my MB and were using them simultaneously each drive would get only 3.0Gb/s /4 = 768 Mb/s max bandwith. So I wanted to clear up my understanding. Side question: Are there other hdd/ssd bandwith bottlenecks to be aware of? (Links to already answered questions are more than welcome)

• Decent 1gb switch (16-24 port) for rack...

  - by TomTom

  Hallo, for a rack containing a smaller nubmer of servers (5 at the moment, going to stay in this area), I look to replace the currently aging 100mbit switch with a 1gb switch. This is for the backend between the servers. I expect some ISCIS traffic there ,so a 10gbit option would be nice (preferably for two ports, as extension modules). I dont need management, this is a pure backend of an internal cluster. I do VLAN, but there is no sensible management the switch can do there. I wuold like: * 1he only, obviously * preferable limited moving parts. * Low price ;) * Enough power to run at least half the ports in full speed at the same time. Anyone any recommendations?

• SSH stops at "using username" with IPTables in effect

  - by Rautamiekka

  We used UFW but couldn't make the Source Dedicated ports open, which was weird, so we purged UFW and switched to IPTables, using Webmin to configure. If the inbound chain is on DENY and SSH port open [judged from Webmin], PuTTY will say using username "root" and stops at that instead of asking for public key pw. Inbound chain on ACCEPT the pw is asked. This problem didn't happen with UFW.

• Kill ssh background process after disconnect / timeout?

  - by keflavich

  I frequently use ssh tunnels to access VNC sessions on remote machines, but this is on my laptop so the connections break when I put it to sleep for the night. If I then try to re-open the connection in the morning, I have to manually kill the ssh session, otherwise I get this error: bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 1202 Could not request local forwarding. The SSH command I'm using is this: ssh -N -C -f -L 1202:localhost:5900 name@server What's the best way to have the ssh tunnel die when it disconnects? Or reset?

• Data recovery from corrupt Ubuntu partition/directory (question about a previous answer)

  - by JoshMaurice

  I have an Ubuntu installation that won't boot anymore. I asked my previous question about it here: http://superuser.com/questions/15916/ubuntu-chkdsk-equivalent Bolotov replied: As I see from your previous question you can boot Windows so you could use dskprobe from Windows XP Service Pack 2 Support Tools to make sure that fs type is correct ... but it's already correct fs type 7 is NTFS. Message "The type of the filesystem is RAW. CHKDSK is not available for RAW drives." means that windows can't determine fs type for some reason. As we see fs type is correct. To run Chkdsk on your Windows partition you can install Windows Recovery Console, boot in recovery console and check your disk. After checking the disk you will gain access to you c:\ubuntu\disks. I think you can mount your linux partition (which is in file) as usual loop-back device: mount -o loop [path to your linux-loopback-partition] But you should mount windows patrition first. So now I'd like to know: Within the recovery console I will be issuing the commands "chkdsk -r" and then "mount -o loop [path to windows partition]" and then "mount -o loop c:\ubuntu\disks", correct? I do have a ("corrupt and unreadable") c:\ubuntu\disks directory so that appears to be the correct path to the linux partition; do you know the path to the windows partition? would that be just "c:\"?

• Apache Server Status page in port 8443

  - by batman

  I'm very new to apache. I tried to enable the server status page of apache. I added the status.conf and status.load to mods-enabled directory. I changed the config of apache2.conf to include all mods-enabled directory. This is the config of staus.conf: <IfModule mod_status.c> # # Allow server status reports generated by mod_status, # with the URL of http://servername/server-status # Uncomment and change the "192.0.2.0/24" to allow access from other hosts. # <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 ::1 # Allow from 192.0.2.0/24 </Location> # Keep track of extended status information for each request ExtendedStatus On # Determine if mod_status displays the first 63 characters of a request or # the last 63, assuming the request itself is greater than 63 chars. # Default: Off #SeeRequestTail On <IfModule mod_proxy.c> # Show Proxy LoadBalancer status in mod_status ProxyStatus On </IfModule> </IfModule> The default settings. I restarted my server. I'm redirecting all ports to 8443. Which in turn turns my requests to localhost:8443/server-status. Which does throw an 404 error. Are there any way to get around this? Thanks in advance.

• port forwarding/network settings preventing from game hosting

  - by Xitcod13

  I asked where to post this question on stackoverflow meta and they directed me here. Im on wireless connection and I want to host games in StarCraft: Brood War and i've been looking everywhere on how to accomplish that. My internet is amazingly fast so its not an internet problem (and when i play other peoples games dont experience lag) I found out that i need to have a static IP but I have already checked that i do (i downloaded a program to make my id static and it already was; The program asked for which router I used So i think it checked the router settings already) I found out that i need to allow Sc access through the firewall which i already did (i have zone-alarm but I allowed it everything possible except receiving emails lol) I have recently noticed that few people actually can join my games but most of them cannot. I dont know whats going on here. I really want to be able to host games overall how do I go about checking what is wrong with the network. Update: Alright I figured out what i did wrong in the first part I did not actually set up forwarding on the router -.- I have tried to fix my mistake. I went to forwarding options in my router (as this guide for my specific router suggests) but when i click ok I get a message incorrect ip address. 192.168.1.1 is my routers address. The default address that appears there is 192.168.1 (blank) I have set it to my computers current Ip4 adress which 192.168.1.23 I hope this works If so i will post it as an answer and mark it.

• saving and searching encrypted mail

  - by user53616

  I often send and receive gpg-encrypted mail. At the moment I use thunderbird + enigmail (in linux) to do that. As far as I know there is no way in thunderbird to find all encrypted messages which bodies contain particular keywords. There also seems to be no option to save encrypted mails decrypted (so they would be searchable). However for me it is important to be able to search old encrypted mails. So my question is: Is there a way in linux to save incoming mails automatically decrypted in my inbox and save outgoing encrypted mail decrypted in the send folder? Both times adding a line to the body which remarks that the mail was encrypted. It could be another email client for linux that could to that or perhaps a solution using procmail or maildrop. For a procmail solution I guess there could be some problems with encoding (perhaps one have to use emil?). Note that the solution should work for multipart encrypted messages (including encrypted attachments) too. Further note that I don't want a discussion about security holes. For me it's ok if messages are stored decrypted on my harddrive (which is encrypted as a whole anyway). In doubt for a first solution it would be ok to store my private key passphrase in cleartext on my harddrive, too. The point is that the mails are encrypted on the mailserver or more generally on their "way through the net".

• virtual machines, dual booting and data disks on SSD

  - by stevemarvell

  This is in planning, so if I've got the strategy wrong, please let me know. There are multiple questions here, but I think they all degenerate to the same answers. The hardware is a laptop with a single SSD. I'm trying to not lose the performance of the SSD. I plan a native dual booting Windows (plus cygwin) and Linux machine which is my BYOD and represents the development environment. I keep the codebase on a shared partition (though sometimes this is an external thunderbolt SSD) which can be natively "mounted" by whichever OS is in operation. I boot into one or the other environments depending on the task in hand. Sometime I have to develop with windows tools, but generally, Linux is my preferred development environment. It would be ideal if I could VM the other OS and run either in either. I'm going to assume, because I've not found a sensible VM based solution, that I have get samba involved to share the code partition between VMs. Is this going to blow my SSD performance in the VM? The client also supplies me with a VM for the target environment, usually linux. This is not often suited to development and is used for testing only. I normally keep two copies of this, one as a sandbox and one which I deploy to using the client's preferred method. I keep these VM snapshots on the shared partition. The latter is interacted with over the network and so has no disk sharing requirements. However, it would be useful for the sandbox to be able to "mount" the code base from the natively running OS. Is this samba or nfs again, depending on the native OS? Am I missing a trick which allows this to all work smoothly with all four environments running at once without loosing the SSD performance?

• SQUID Transparent SSL proxy (no intercept)

  - by user974896

  I know how to have squid work as a transparent proxy. You put it into transparent mode then use your router or IPTABLES to forward port 80 to the squid port. I would like to do the same for SSL. Every guide I see mentions setting up keys on the squid server. I do not want squid to actually decrypt the SSL traffic then establish a connection with the server, rather I would like squid to simply forward the SSL traffic as is. The only thing I would like to do is be able to check the SSL request for any offending IPs and drop the packets if the destination is one of them.

• Short, intermittent USB port timeouts

  - by jacobsee

  I have a data acquisition application controlled by a Windows PC. I am using an Intel Desktop Board DH67CL motherboard. This has 6 USB2 ports along with 2 of the new blue USB3 ports. The DAQ instrument connects via USB to the computer. Roughly once every day or two there is a short communication glitch with the USB that causes the instrument to disconnect briefly and then reconnect. This is logged so I know whenever it happens. Occasionally it will cause the data acquisition to stop. I've verified that the glitches will go away if I use the USB3 ports, or if I use a PCI add-on card with USB ports. So it seems that there is something going on with these built-in USB2 ports on this motherboard. I haven't yet had a chance to test with other motherboards. My question: what could be causing these glitches and how to get rid of them for this board, or is there a better motherboard to use? We have standardized on the DH67CL because it's inexpensive, has 3 PCI slots that we need, and is readily available. We don't need the power of higher-end server boards but reliability is important. Thanks. Update: This problem has been reproduced many times on different hardware, though we always use the same model of motherboard (DH67CL) and power supply (Antec EA-430D). I don't think the power requirements are very high but will check on that.

• DVD-burner disappears when using grub

  - by drblah

  This is a rather annoying problem I have with Linux on my laptop. Whenever I install any Linux distro that relies on grub (which is about 99 % apparently) it will mess up my DVD-drive and the drive will not be recognized after booting, no matter the OS (Ubunntu, Arch, Windows Vista or 7). I know the problem has nothing to do the DVD-drive itself, because I bought a new one a few months ago. I am also sure that grub is messing the drive up, because I have tried to use LILO, which worked fine (except for horrible boot times.) This problem have persisted through about 3-4 years and it is a pretty bad show stopper whenever I want to work with Linux. I had hoped it would get fixed over time, but no one seems to have the exact problem I have. The drive is connected with an IDE connection. Update: The old drive was a Toshiba Samsung SN-S082. I don't know the model number of the new one, but it is HP (I think). Things I have tried to fix it: Mess about with some BIOS settings like enabling AHCI and change some IDE settings. Installing a different boot loader DOES fix the problem but I would like to use grub.

• How to set static ip address on vmware for NAT guest vms from an ubuntu Host dhcp server?

  - by javadba

  I need to configure various linux flavor NAT'ed guest vm's to have static ip addresses provided by the Ubuntu host. The vmware documentation punts on this topic, deferring to "see the man pages for your linux distribution". But the generic pages for "my linux distro" do not know about the special stuff for vmware e.g. vmnet8. Pointers from someone who just knows how to do this would be much appreciated. Here is the /etc/vmware/vmnet8/dhcpd/dhcpd.conf: allow unknown-clients; default-lease-time 1800; # default is 30 minutes max-lease-time 7200; # default is 2 hours subnet 192.168.238.0 netmask 255.255.255.0 { range 192.168.238.128 192.168.238.254; option broadcast-address 192.168.238.255; option domain-name-servers 192.168.238.2; option domain-name localdomain; default-lease-time 1800; # default is 30 minutes max-lease-time 7200; # default is 2 hours option netbios-name-servers 192.168.238.2; option routers 192.168.238.2; } host vmnet8 { hardware ethernet 00:50:56:C0:00:08; fixed-address 192.168.238.1; option domain-name-servers 0.0.0.0; option domain-name ""; option routers 0.0.0.0; } Fromt the dhcpd.conf documentation, we are supposed to add an entry for static hosts similar to the following: host mystatichostonee { hardware ethernet 00:20:6B:C7:9B:E4; fixed-address 192.168.238.101; } host mystatichosttwo { hardware ethernet 00:23:7a:C7:9c:F2; fixed-address 192.168.238.102; } But notice that the vmnet8 entry in the vmware-generated dhcpd.conf already is set to fixed-address. I don't know how to add the specifics for my hosts to that vmnet8 entry: do they become nested?

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  Hi, I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• ssh works fine when using public interface, but slow when using private interface

  - by Kevin M

  My Linux(UbuntuEEE) to Linux(CentOS) ssh takes a long time to log in(~15 seconds) when using the private interface, but not when using the public one. I have a Linux box acting as my router. As such, it has multiple interfaces(75.xxx.xxx.xxx, 192.168.1.1). I can ssh in from the internal interface(192.168.1.65 to .1), but it will take a while. I can ssh into the public address, and it goes quickly(~1 second). I have another box that I can ssh into the inside interface from and it goes quickly. iptables is set to accept packets coming into the interface immediately. sshd's UseDNS is normally on; I get the same problem if I turn it off and restart sshd. I normally use public-key authentication; I have done a mv ~/.ssh/ ~/ssh/ and it will ask me for a password after going slowly. After logging in(using either interface), speed is quick. ssh client version(via ssh -v):OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 ssh server version(via rpm -qv openssh_server):openssh-server-4.3p2-29.el5

• How do I get a network printer installed in ubuntu 9.04?

  - by SoaperGEM

  My girlfriend's work computer now has Linux on one of the partitions, and for the most part it's running fine--except that I can't seem to get the network printers configured right. There are two of them: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong. I went to Administration Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as socket://[ip address]:9100. I changed these to lpd://[ip address] per some online tutorial, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said Processing (and sometimes even Processing - printing test page, 4%, but always subsequently displays Idle - /usr/lib/cups/backend/lpd failed. Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong?

  Commmand works on the host I need to monitor (its IP is denoted as $HOSTADDRESS$ here): [root@host ~]# /usr/local/nagios/libexec/check_ssh localhost SSH OK - OpenSSH_4.3 (protocol 2.0) However, on the Nagios server, it does not: root@server:~# /usr/lib/nagios/plugins/check_ssh -H $HOSTADDRESS$ Server answer: I can see that the port is open: root@server:~# /usr/lib/nagios/plugins/check_tcp -H $HOSTADDRESS$ -p 22 TCP OK - 0.123 second response time on port 22|time=0.123277s;;;0.000000;10.000000 And I can verify with telnet: root@server:/etc/nagios3/conf.d# telnet $HOSTADDRESS$ 22 Trying $HOSTADDRESS$... Connected to $HOSTADDRESS$. Escape character is '^]'. After searching the web for two hours and trying different suggestions I am out of ideas. I have several other hosts with similar setup, and they don't have this problem. I have compared the configs and they look the same (I think). I am clearly missing something here.
