  • Howto detect fake RAM

    - by Michael
    I just bought a virtual server which should have 2GB of RAM. Now i got a server with 4gb which looks very strange to me. I think it is just a virtual RAM. dmidecode only ouputs /dev/mem: Operation not permitted How can i check if it's a real RAM or just a virtual one? free -m outputs: total used free shared buffers cached Mem: 4093 364 3728 0 0 346 -/+ buffers/cache: 18 4074 Swap: 0 0 0 Output from cat /proc/user_beancounters Version: 2.5 uid resource held maxheld barrier limit failcnt 137: kmemsize 8922287 10194944 2145910784 2145910784 0 lockedpages 0 0 523904 523904 0 privvmpages 13387 59112 9223372036854775807 9223372036854775807 0 shmpages 769 785 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 numproc 22 54 9223372036854775807 9223372036854775807 0 physpages 93377 106010 0 1047808 0 vmguarpages 0 0 9223372036854775807 9223372036854775807 0 oomguarpages 2471 2473 9223372036854775807 9223372036854775807 0 numtcpsock 5 21 9223372036854775807 9223372036854775807 0 numflock 4 13 9223372036854775807 9223372036854775807 0 numpty 1 1 9223372036854775807 9223372036854775807 0 numsiginfo 0 39 9223372036854775807 9223372036854775807 0 tcpsndbuf 102592 381632 9223372036854775807 9223372036854775807 0 tcprcvbuf 81920 4820184 9223372036854775807 9223372036854775807 0 othersockbuf 4624 61632 9223372036854775807 9223372036854775807 0 dgramrcvbuf 0 9248 9223372036854775807 9223372036854775807 0 numothersock 39 56 9223372036854775807 9223372036854775807 0 dcachesize 4178917 4232732 1072955392 1072955392 0 numfile 378 535 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 numiptent 24 24 9223372036854775807 9223372036854775807 0

  • How to load kernel module at startup on FC9?

    - by dicroce
    I need to know how to automatically load a kernel module at startup on FC9. All the sites talk about adding an entry to /etc/modules.conf.... But that does not exist on FC9... Instead I have /etc/modprobe.d/ directory... Now, I suppose I need to put a file in this dir for my driver but I have no idea how to write this file... I just need "modprobe name" to be run...

  • Mail Server with Google Apps

    - by Daniel Fukuda
    Hello, Is there any mail server that has a feature to download (POP3) emails from another mail server like Google Apps (Gmail for your own domain), store it and then allow to users to download (POP3/IMAP) emails to their own mail client like Outlook/Live Mail? So I want it to become like a "middle mail server". I hope you guys understand it. My main reason to do so is that Google Apps got limited space for each mailbox and I also want to have emails in one space so its easy to archive and backup.

  • Why does Exim puts emails on hold if there are frozen messages in the queue?

    - by user51932
    Hi, I've a CentOS with CPanel server working as a SMTP server, which currently uses 20 different hostnames and IP addresses to deliver email for an email newsletter service. However, it's extremely slow in sending emails. It's sending like 10 emails per minute, which I check by running the "exim -bpc" command. What could be affecting this? One thing I'm supposing, is that there are frozen messages in the queue, which are slowing down the sending until they're sent out, and are putting new messages on hold. What are the most common reasons a message can get frozen? Also, would it be more efficient to use 20 different small VPSs to send out email rather than use one large VPS with the 20 different hostnames and IPs in it?

  • How do I get openssh to save my ssh identity permanently in Xfce?

    - by Alliswell
    How do I change it to save my identity permanently using Xfce? During my login session after I have entered: $ ssh-add Then identity is saved and I can connect via ssh without getting the dreaded: Enter passphrase for key However, once I logout and login back-in I get the following when running: $ ssh-add -L The agent has no identities. $ ssh <hostname> Enter passphrase for key '/home/user/.ssh/id_rsa': Stackoverflow has the following solution, yet I do not understand the reference to in the config file: IdentityFile ~/.ssh/id_rsa_buhlServer Specifically I do not understand what I would put on the identity file. Would I put the above word for word? Or just add my file: IdentityFile ~/.ssh/id_rsa StackOverflow solution

  • sticky bit on NFS file system

    - by Kris_R
    I have a system where to the main server (homes, nfs, ntp, queue...) can log-in only root – all the other users use front-end host with NFS-mounted home directories (RW) and all other software directories (read-only). My problem is, that time to time, if root or normal user with sudo makes some administrative works on front-end some homes of normal users getting sticky bits (drwsr-sr-x). If it happens usually the user can't log-in (as long as permission for his home are not changed to drwxr-xr-x). The last time I saw it after compiling some new software (normal user configure;make) and installation from the same directory as root (su and make install or direct as normal user sudo make install). Can somebody explain me why it happens and what should I do to get rid of this problem? p.s. I'm using CentOS 5.7

  • Preventing an Apache 2 Server from Logging Sensitive Data

    - by jstr
    Apache 2 by default logs the entire request URI including query string of every request. What is a straight forward way to prevent an Apache 2 web server from logging sensitive data, for example passwords, credit card numbers, etc., but still log the rest of the request? I would like to log all log-in attempts including the attempted username as Apache does by default, and prevent Apache from logging the password directly. I have looked through the Apache 2 documentation and there doesn't appear to be an easy way to do this other than completely preventing logging of these requests (using SetEnvIf). How can I accomplish this?

  • What are the different file permission codes and what do they mean?

    - by zeckdude
    I am working with a file upload script. I am currently uploading a file and then trying to echo out an anchor linking to that file, but since I used mkdir() with 0700 permissions to upload the file, it won't allow me access to view the file. I am pretty sure the problem I am experiencing is because of the file permission code I used. The problem is I just don't know what all the different file permission codes are and what they mean. Can somebody please list out all the different file permissions and what they each do?

  • How do I upgrade to PHP 5.4 in CentOS 6.3 with yum?

    - by Vicary
    I found some blog posts about this, but it's rather lack of descriptions on possible side effects. I could really use some detailed on these steps: How to add a repo that provides PHP 5.4 into yum Can this seamlessly replaces the current PHP version in CentOS? How can I switch back to the official repo when it supports PHP 5.4? (current 5.3.3 in my system) Will there be any potential to break PHP modules I currently using?

Can anyone please explain to me clearly? I am using CentOS 6.2.

  • Ignore Apache Default Server?

    - by Jakobud
    I run several vhosts on our Apache server. Whenever browse the server using either it's IP address or some other name that resolves to that address, but where a virtual host entry doesn't exist for that address I get the generic Apache test page: I want to change the server so I can specify a Virtual Host to see by default instead of the Apache Default Server page. I don't want to just modify the Default Server page either. I just need to be able to specify a Virtual Host to use instead. I added the following Virtual Host: <VirtualHost _default_:*> DocumentRoot /vhosts/default/public </VirtualHost> What I am reading is supposed to take priority over all other Virtual Hosts as the default. But this doesn't seem to take priority over the Apache Default Server/Host. What do I need to do here?

  • SSH + SAMBA + LDAP question

    - by Mejmo
    Hi, I have SSH + LDAP working (I can log to Server2 with credentials from LDAP server Server1). Now, I would like to add Samba server (Server3) and it would be nice if it authenticates the users like Server2. How can I achieve this ? As I see Samba schema and the schema used for storing Unix users are different. So if I change password in Samba schema, I would be able to log in with the old password. I need centralized storage of username/passwords. If I change it once in phpldapadmin, it means for samba and ssh. Thanks.

I tried to simulate the process and lock test mailbox but I couldn't, I was aiming to understand who can lock ? who has exclusive access ? and why only client server can lock ? and how to solve this ?

  • Using u32 together with extension headers (how to jump over them?)

    - by bortzmeyer
    I'm trying to filter on some parts of the payload, for an IPv6 packet with extension headers (for instance Destination Options). ip6tables works fine with conditions like --proto udp or --dport 109, even when the packet has extension headers. Netfilter clearly knows how to jump over Destination Options to find the UDP header. Now, I would like to use the u32 module to match a byte in the payload (say "I want the third byte of the payload to be 42). If the packet has no extension headers something like --u32 "48&0x0000ff00=0x2800"` (48 = 40 bytes for the IPv6 header + 8 for the UDP header) works fine, If the packet has a Destination Options, it no longer matches. I would like to write a rule that will work whether the packet has Destination Options or not. I do not find a way to tell Netfilter to parse until the UDP header (something that it is able to do, otherwise --dport 109 would not work) then to leave u32 parse the rest. I'm looking for a simple way, otherwise, as BatchyX mentions, I could write a kernel module doing what I want.

  • Soap client call has slow performance

    - by Alon_A
    OS is Centos 6.2 with PHP 5.3.15. We have a Facebook application that is using PHP soap web services. We sometimes experince slow preformance when connecting to these services, but we cant understand what exacly is causing the problem. We've try to analyse the behavior using the profiling tool Kcachgrind. Here is a call graph from the index.php page that took 21 seconds to load. You can clearly see that calling the soap client is the bottle neck. I've also noticed that exactly before the page finishes to load, this file is being created in our serve's /tmp folder: wsdl-apache-d1032d85dfd16c0d91a6b70facc70e43 These are the permission of /tmp drwxrwxrwt 6 root root 40960 Aug 30 10:39 tmp I know its not the most specific question, but if any one had similar performance issues with soap client, We would love some ideas about what can cause this kind of performance problem, what can we do to investigate more accurately or how to overcome the problem ? Thanks.

  • Configure firewalld for OpenVPN (server-bridge) in Fedora 20

    - by rsc1975
    I've installed an OpenVPN server (server-bridge) on Fedora 20, but I cannot get it to work. I'm almost sure that It's a firewall issue. I'm trying to connect from an OSX client, but I can connect (just connect to VPN server, without access to anything) before the bridge is configured in server, however once I configure the bridge interface (using this script), then I cannot connect anymore. I've configured it as server-bridge, following these HOW-TOs from Fedora and OpenVPN Ethernet-Bridge. The firewall config is explained using iptables: iptables -A INPUT -i tap0 -j ACCEPT iptables -A INPUT -i br0 -j ACCEPT iptables -A FORWARD -i br0 -j ACCEPT However, in Fedora 20, by default, It's installed firewalld, so, Can anyone tell me the equivalent commands using firewall-cmd ? I read the firewalld guide, but It's not clear to me how to achieve it (I'm a developer, no SysAdmin). I know that I can install iptables, but I want it to work with firewalld.

  • Ubuntu USB flash boot drive gets spontaneous "Unhandled sense code" error and causes drive to switch to Write protected

    - by Steve
    What happens is that the system runs fine for several days or even a week and then suddenly the root file-system / goes read-only. Looking at the syslog it shows that there was an 'Unhandled sense code'. This is under Ubuntu 10.04 but I saw the same thing with Ubuntu 9 with different flash media. /dev/sdg1 on / type ext4 (rw,errors=remount-ro) Jun 26 08:50:04 host1 kernel: [926247.565090] sd 5:0:0:0: [sda] Unhandled sense code Jun 26 08:50:04 host1 kernel: [926247.565094] sd 5:0:0:0: [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE Jun 26 08:50:04 host1 kernel: [926247.565098] sd 5:0:0:0: [sda] Sense Key : Data Protect [current] Jun 26 08:50:04 host1 kernel: [926247.565103] sd 5:0:0:0: [sda] Add.

  • What is the best time to set the IP address for a server headed to a server colocation facility?

    - by jim_m_somewhere
    What is the best time to set the IP address for a server? I have a server that I am going to install the OS on and then I am going to send it to a server colocation facility. The server is going to have Internet facing services (www, email, etc.) I can set up a "fake" IP address during install (by fake I mean private as in RFC 1918) and change the "fake" IPs to the real IPs once I set up the colocation service. The other option is to set up the colocation service...wait for them to give me the "real" IPs and use them during the OS install. The ramification are that...if I use "fake" IPs during install...I will have to wait before I set up things like SSL certs. If I wait for IPs from the colocation provider...then I can set up SSL certs that use the "correct" (as in "real") IP addresses...no changes to the certs until they expire. Do the "gotchas" of changing an IP address on a server outweigh the benefits of a quick install? The other danger with using "fake" IPs is that I could make a mistake when I go through the various files to change the IP address to the "live" IP address. Server OS: CentOS 6.2 or CentOS 6.3, 64 bit. Apps: Apache 2.4.X httpd, MySQL 5.X (will eventually use replication)
