  • Deployment and Ownership issues

    - by kylemac
    As an extreme newbie, I am having difficulty managing ownership and permissions on my first box. What I can't figure out is how to deploy using one user, we will call him deploy and operate my php application with www-data user. Currently as it stands, I know my server runs as www-data through this function <?php echo(exec("whoami")); ?> but I am having to chown between deploy and www-data every time I deploy. There has got to be an easier way to deploy with one user and still run as www-data. EDIT: Here is the output from ls- l on the folder in question. You will see user deploy and group www-pub, the group is from an attempt to add the two different users to a new group and chown one of them in the hopes that they both would have the permissions (newb alert) drwxrwxr-x 4 deploy www-pub 4096 Mar 7 01:41 example.com I am using capistrano for deployment under the user deploy then once its done i chown to www-data, otherwise I can't use php to manipulate files. I am also unsure how to even change which user apache is running.

  • Xorg input devices fail without udev

    - by Sampo
    What I am trying to do: Launch Xorg server without udev device manager. What I have tried to do: Make sure that /dev/ has all required nodes, such as /dev/input/*. Make sure that all required kernel modules are loaded. Launch Xorg. What happens: Xorg starts up as excepted. Xorg loads correct GPU driver and sets right screen resolution. Xorg blocks all input devices (keyboard, mouse), Alt+F[1-12] does not work (can't go back to tty1). Unraw'ing keyboard to take its control from X removes blocking and after unraw I can Alt+F1 back to tty1. Xorg still does not handle any input. Why I think that it should work: Same configuration works well if udev is loaded. Loading udev does not add or modify /dev/ contents, all nodes stays same. My main question is: How to make Xorg input devices work without udev? Any additional information about how Xorg really uses/detects/grabs keyboard would be helpful. And any additional information about what udev really does (other than populating /dev/) would also be helpful.

  • External routing for local interfaces in a virtualized network

    - by Arkaitz Jimenez
    Current setup: br0| |-- tun10 -pipe-tun0(192.240.240.1) |-- tun11 -pipe-tun1(192.240.240.2) |-- tun12 -pipe-tun2(192.240.240.3) The pipe program is a custom program that forwards data back2back between two tun interfaces. The idea is puting 2 programs in .2 and .3 while keeping .1 as the local interface in the current machine. The main problem is that I want to route packets to .2 and to .3 through .1 and br0, but as they are local interfaces, the kernel ignores any routing instruction, it just delivers the packet to the proper interface. Tried iptables, but the nat table doesn't even see ping packets to those ifaces. A "ping 192.240.240.2" delivers a icmp packet with source and dest .2 to tun1, ideally it should deliver a source .1 dest .2 at tun1 through tun0-br0-tun1 Any hint? Here the output of some commands: Output

  • pthread-stubs for CentOS

    - by Rodnower
    Hello, I try to install Mesa 7.8 for CentOS 5. During installation of Mesa I required to install librdm, and during librdm (v. 2.4.19) installing I got error about missing pthread-stubs: checking for PTHREADSTUBS... configure: error: Package requirements (pthread-stubs) were not met: When I try: yum provides *pthread-stubs* I get nothing In other place I found that libxcb-devel is what I need, but yum not find this too. During searching in Google, I found rpm's for Fedora only. Any one know whether there is some packege which provides pthread-stubs for CentOS, or other, less expensive way to install Mesa? Thank you for ahead.

  • copy boot-able partition

    - by Dima
    I have an disk image with 3 partitions: first partition (hd0,0) is boot-able with GRUB1 with the following configuration GRUB file: default=0 timeout=5 title Bank A root (hd0,1) chainloader +1 title Bank B root (hd0,2) chainloader +1 The partitions (hd0,1) and (hd0,2) are also boot-able. I'm trying to clone partition (hd0,1) to (hd0,2) by creating device map using kpartx and copying whole partition using dd command. The problem is: after partition cloning, the cloned partition did not boot (but all files are OK). What the wrong? I need both partitions to bee identical (I'm using them for fail-over purposes into embedded device)

  • Iptables: "-p udp --state ESTABLISHED"

    - by chris_l
    Hi, let's look at these two iptables rules which are often used to allow outgoing DNS: iptables -A OUTPUT -p udp --sport 1024:65535 --dport 53 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -p udp --sport 53 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT My question is: How exactly should I understand the ESTABLISHED state in UDP? UDP is stateless. Here is my intuition - I'd like to know, if or where this is incorrect: The man page tells me this: state This module, when combined with connection tracking, allows access to the connection tracking state for this packet. --state ... So, iptables basically remembers the port number that was used for the outgoing packet (what else could it remember for a UDP packet?), and then allows the first incoming packet that is sent back within a short timeframe? An attacker would have to guess the port number (would that really be too hard?) About avoiding conflicts: The kernel keeps track of which ports are blocked (either by other services, or by previous outgoing UDP packets), so that these ports will not be used for new outgoing DNS packets within the timeframe? (What would happen, if I accidentally tried to start a service on that port within the timeframe - would that attempt be denied/blocked?) Please find all errors in the above text :-) Thanks, Chris

  • Cygwin unable to compile

    - by christine
    I just downloaded Cygwin, I've never used it before cause I've always used putty. Cygwin is not letting me compile; I can see the files but it just doesn't let me compile and I do not understand why, am I doing something wrong? This is what's going on: Christine@Christine-PC ~ $ ls 8.6.c a.b.c a.c.c core new 2.txt test.c 9.13.c a.c a.out days.c new2.c test.txt Christine@Christine-PC ~ $ gcc a.c.c -bash: gcc: command not found

  • How to reverse-i-search back and forth?

    - by m-ric
    I use reverse-i-search often, and that's cool. Sometime though when pressing Ctrl+r multiple times, I pass the command I am actually looking for. Because Ctrl+r searches backward in history, from newest to oldest, I have to: cancel, search again and stop exactly at the command, without passing it. While in reverse-i-search prompt, is it possible to search forward, i.e. from where I stand to newest. I naively tried Ctrl+shift+r, no luck. I heard about Ctrl+g but this is not what I am expecting here. Anyone has an idea?

  • How to do a hexdump of first track of HDD?

    - by Daniel Gratz
    How would i do a hexdump in Ubuntu for the first track of a HDD? I am looking for a winhex-esque output if that makes sense. The first track has 63 sectors, each 512 bytes long. I tried dd if=/dev/sda bs=1 count=512 | hexdump -C but that only gave me what appears to be the MBR, or first sector of the HDD. I guess i am confused about what bs and count should be. Bs means how many bytes to display and count is how many multiples of bs? Thanks!

  • Where is all the memory being consumed?

    Hello, I have a Dell R300 Ubuntu 9.10 box with 4GB of memory. All I'm running on there is haproxy, nagios and postfix yet there is ~2.7GB of memory being consumed. I've run ps and I can't get the sums to add up. Could anyone shed any light on where all the memory is being used?

  • rc.local is not executed on bootup ubuntu

    - by Alexander
    Im on Ubuntu 10.04. I want to execute script on system boot. I added it to rc.local. If I execute rc.local manually it works fine. If I boot system in recovery mode(2nd string in boot menu) it also works fine. But if I boot normally it is not executed. However i added sleep 20 to my script and there is a pause at the end of boot process, but nothing more is executed. Thanks I think, it soesnt depend on contents of the script but anyway #!/bin/sh -e sleep 20 sudo service ssh start su -c 'service pgsql start' postgres sudo svnserve -d su -c 'hamachi start' root su -c 'hamachi login' root exit 0

  • Problem with testsaslauthd and kerberos5 ("saslauthd internal error")

    - by danorton
    The error message “saslauthd internal error” seems like a catch-all for saslauthd, so I’m not sure if it’s a red herring, but here’s the brief description of my problem: This Kerberos command works fine: $ echo getprivs | kadmin -p username -w password Authenticating as principal username with password. kadmin: getprivs current privileges: GET ADD MODIFY DELETE But this SASL test command fails: $ testsaslauthd -u username -p password 0: NO "authentication failed" saslauthd works fine with "-a sasldb", but the above is with "-a kerberos5" This is the most detail I seem to be able to get from saslauthd: saslauthd[]: auth_krb5: krb5_get_init_creds_password: -1765328353 saslauthd[]: do_auth : auth failure: [user=username] [service=imap] [realm=] [mech=kerberos5] [reason=saslauthd internal error] Kerberos seems happy: krb5kdc[](info): AS_REQ (4 etypes {18 17 16 23}) 127.0.0.1: ISSUE: authtime 1298779891, etypes {rep=18 tkt=18 ses=18}, username at REALM for krbtgt/DOMAIN at REALM I’m running Ubuntu 10.04 (lucid) with the latest updates, namely: Kerberos 5 release 1.8.1 saslauthd 2.1.23 Thanks for any clues.

  • Reboot VPS by reaching memory limit

    - by Ali
    When a server uses memory more than available RAM, the system will shut down the virtual machine. Then, it is only possible to boot from outside (VPS control panel, e.g. vePortal or SolusVM). However, it should be possible to plan a reboot before possible shut down. What is the best practical method to check the used memory, and reboot the system upon reaching e.g. 90% of the allowed RAM? Is there a common program or script to do so? I am using Debian/Ubuntu.

  • Empty /var/log after running cron bash script

    - by Ortix92
    I wrote a little bash script and all of a sudden my /var/log folder is completely empty except for the log I created for the bash script. This is the script I'm running every hour with cron: #!/bin/bash STL_DIR=/path/to/some/folder/i/hid LOGFILE=/var/log/stl_upload.log now=`date` echo "----------Start of Transmission----------" 2>&1 | tee -a $LOGFILE echo "Starting transfer at $now" 2>&1 | tee -a $LOGFILE rsync -av -e ssh $STL_DIR [email protected]:/users/path/folder 2>&1 | tee -a $LOGFILE echo "----------End of transmission----------" 2>&1 | tee -a $LOGFILE printf "\n" 2>&1 | tee -a $LOGFILE I want to be clear that I'm not 100% certain this is related to the empty logs folder. So if anyone could give me a pointer as to what could be going on about the reason why my log folder is empty, that'd be great.

  • NetFlow Storage Calculator

    - by javano
    I am planning to deploy a NetFlow server (using NfSen/NfDump) for harvesting data from Cisco devices; Are there standard calculations or guidelines I can use to calculate my server requirements, specifically I need to plan for storage. Is there a way of knowing how much data I will collect per day for example, given N flows? Lets say one device has 10k flows per day, this is typically XYZ MBs, so I can scale this up? If not, how many flows are you guys and girls recording per day, and how much data is this generating? Hopefully we can generate an estimate from everyone else's figures! P.S. If it makes a difference, I'll be collecting from <= 50 devices max (non more than 50Mbps each).

  • arp -n responds with (incomplete) on the wrong subnet, can't remove it

    - by Hannes
    context There are 2 servers: server1 - eth0 10.129.76.16 eth0.2 192.168.0.103 server2 - eth0 10.129.79.1 eth0.2 192.168.62.101 The 192.x.x.x addresses are connected to the same vlan (vlan2) and are able to see eachother. The 10.x.x.x addresses are connected to different vlan's which are not able to see eachother. on request of David Swartz: the routing table on server 1 is: ~$ sudo route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.129.76.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.192.0 U 0 0 0 eth0.2 0.0.0.0 192.168.61.254 0.0.0.0 UG 100 0 0 eth0.2 the routing table on server 2 is: ~$ sudo route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 <public IP gw> 0.0.0.0 UG 100 0 0 eth0.11 10.129.79.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 <public IP> 0.0.0.0 255.255.255.128 U 0 0 0 eth0.11 192.168.0.0 0.0.0.0 255.255.192.0 U 0 0 0 eth0.2 Problem: When I ping from server 1 to server 2, it seems no packets are arriving and vice versa. When I check the routes (route -n) I see the default gw uses eth0.2 on both servers. But when I use arping, I get a response one way (from server 2 to server 1) but no response vice versa. arping 192.168.62.101 ARPING 192.168.62.101 from 10.129.76.16 eth0 ^CSent 2 probes (2 broadcast(s)) Received 0 response(s) As you can see it uses the 10.x.x.x address instead of the 192.x.x.x. And as I told before, the 10.x.x.x address is unreachable from the other server. When I force arping to use eth0.2, it does work. I don't have any problems with ping'ing other servers from any of those 2 servers. I did see this in the arp tables: ~# arp -n | grep 192.168.0.103 192.168.0.103 (incomplete) eth0 and ~# arp -n | grep 192.168.62.101 Question quite obvious... How can I make these servers see each other again? Things I've tied clear the apropriate entries in the arptable and tried to get rid of the (incomplete) But I think the biggest problem is that eth0 is used instead of eth0.2 for the packets from server 1 to server 2 Because of David Swartz' remark about the routing tables, I added a route in there defining the host. I added 192.168.0.103 0.0.0.0 255.255.255.255 UH 0 0 0 eth0.2 and 192.168.62.101 0.0.0.0 255.255.255.255 UH 0 0 0 eth0.2 to the appropriate servers but this didn't solve the problem so I presume the problem is not in the routing. My guess I guess the problem lies in the following. ~$ arp -n | grep 192.168.0.103 192.168.0.103 (incomplete) eth0 but I'm unable to remove this entry. (arp -d 192.168.0.103 has no effect) Thanks for reading and even more thanks for answering!

  • Using public interfaces on a server connected through a GRE tunnel

    - by Evan
    I'm pretty new to networking so please forgive any terminology mistakes. I have 2 servers connected with a GRE tunnel. Server1 (10.0.0.1) ---- Server2 (10.0.0.2) I want to be able to bind to the public IPs on Server2 using Server1. To do this, I setup virtual interfaces with Server2's public IPs on Server1 and then used routing rules on Server1 to route the packets through the GRE tunnel. On Server1: ip rule add from [Server2's first public IP] table gre ip rule add from [Server2's second public IP] table gre ip route add default via 10.0.0.2 dev gre1 table gre This works great and I can see the packets arriving via GRE on Server2. I can see the packet exiting the tunnel on Server2's gre1 device as shown: From Server1: ping -I [Server2's public ip] google.com tcpdump from Server2's GRE tunnel device: 12:07:17.029160 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) [Server2's public ip] > 74.125.225.38: ICMP echo request, id 6378, seq 50, length 64 This is exactly the packet I want. However, I'm not seeing it go out at all on eth0:0 (where Server2's public IP is bound to). I've tried to use routing rules to get packets coming from Server2's public IP (which would be coming out of dev gre1) to go through dev eth0 on the public default gateway and that doesn't work either. I'm at a loss, thank you to anyone who can help.

  • how to make a php crontab silent

    - by BandonRandon
    I set up a crontab in Cpanel to run every min. It's working great but I don't want an e-mail every min. I have a second cron tab that runs every day. I would like the responce of this tab. Is there a way to tell the crontab to be silent or only e-mail on error? I have: * * * * * php /home/public_html/folder/file.php 2>&1 The last bit 2>&1 I added because i thought it would make it silent. From the Cpanel Docs: You can have cron send an email everytime it runs a command. If you do not want an email to be sent for an individual cron job you can redirect the command's output to /dev/null like this: mycommand /dev/null 2&1

  • Video desktop recording and multiple WM displays, capturing nonactive display

    - by okobaka
    Two WM running on one local machine. WM - Fluxbox. Using ffmpeg to record desktop. ffmpeg -an -f x11grab -s 1920x1080 -r 25 -i :1.0 -sameq /tmp/video.mkv On one display everything works great, but not when i have another WM display startx -- :1. What i am doing right now is to switch ctrl+alt+f8 to display:1.0, and start recording with ffmpeg. Everything is fine until i switch back ctrl+alt+f7 to display:0.0, WM and captured video image freezes, but when i switch back ctrl+alt+f8 to display:1.0, it unfreeze and continue recording. So, how to make display:1.0 not to freeze, while on display:0.0? Tested some more. open [display 0.0] open [display 0.1] from [display 0.0] = open => [display 0.2] same problem For different users and same users results are the same. ffmpeg keeps recording that paused image. Looks like WM root window need to be active, to be recorded.
