  • Is there a decent diagram of packet flow for a modern era (2.6+) iptables setup?

    - by stsquad
    I'm currently trying to debug a particularly hairy set of DNAT based iptables rules (the UDP reply never makes it back to the original requester) and I'm struggling to visualise the packet flow through all the numerous tables involved. So far Google'ing has shown me old 2.4 based ipchains ones. The netfilter site has some good text docs but is short on diagrams and a number of the external links are now dead. So is there a canonical diagram for iptables packet flow, preferably showing how NAT/Masqueraded packets are also dealt with?

  • How to change the X-Windows default border width for all window frames in Ubuntu using Gnome 2.28

    - by Heston T. Holtmann
    Way back from Windows 3.x days to the latest 64bit Windows 7 (classic/standard theme).. there is a way to make the window edge border wider then 1 pixel... I often use 3 to 5 pixel to make it easy to grab on hi-resolutions displays and hi DPI monitors. There doesn't seem to be an easy or obvious way to do this with the Gnome X-Windowing system? Does any one know how?

  • Backing Up User Data when data is not in use. Should I be concerned?

    - by jberryman
    This may be a dumb question. I would like to use duplicity to make backups to Amazon S3 of directories, each of which contains a different user's data. Each directory could be written to at any time. So I have two questions: Should I be concerned that a scheduled backup of a directory might occur in the middle of data being written to files in the directory, resulting in a corrupted backup? And if that is a valid concern, how would I go about temporarily delaying an operation while IO was happening, to try to minimize that effect. Thanks for the advice

  • how to design LAN connectivity between private and corporate ?

    - by maruti
    there is a bunch of servers connected to shared storage in a private LAN (10.x.x.x). this privateLAN is managed by a windows server (DHCP, DNS and directory services). how can these hosts be accessed from outside of this privateLAN? Eg. Remote desktop. can the NIC2 on each of the hosts be connected to the other public LAN (compromising speed or security? what are improtant considerations: additional hardware? like switches? routing&DNS software?

  • Apache logs other user read permissions

    - by user2344668
    We have several developers who maintain the system and I want them to easily read the log files in /var/log/httpd without needing root access. I set the read permission for 'other' users but when I run tail on the log files I get permission denied: [root@ourserver httpd]# chmod -R go+r /var/log/httpd [root@ourserver httpd]# ls -la drwxr--r-- 13 root root 4096 Oct 25 03:31 . drwxr-xr-x. 6 root root 4096 Oct 20 03:24 .. drwxr-xr-x 2 root root 4096 Oct 20 03:24 oursite.com drwxr-xr-x 2 root root 4096 Oct 20 03:24 oursite2.com -rw-r--r-- 1 root root 0 May 7 03:46 access_log -rw-r--r-- 1 root root 3446 Oct 24 22:05 error_log [me@ourserver ~]$ tail -f /var/log/httpd/oursite.com/error.log tail: cannot open `/var/log/httpd/oursite/error.log' for reading: Permission denied Maybe I'm missing something on how permissions work but I'm not finding any easy answers on it.

  • Why would the Apache parent process restart silently?

    - by miracle
    I run apache 2.2.9 with mpm prefork on debian lenny. Following http://httpd.apache.org/docs/2.2/mod/prefork.html, I would expect that there is one parent process, running as root and listening as configured, which would start child processes as defined by the Min/Max/etc. directives. I expect the children to be restarted as per MaxRequestsPerChild, but the parent process to stay put with one process id until I restart it manually. Out of a little paranoia, I started monitoring listening ports including process ids. I have a cron job every 20 minutes to run netstat -ap | grep LISTEN and diff the output. Sometimes (about once per day) I see a series of this: 8c8 < tcp6 0 0 [::]:www [::]:* LISTEN 6194/apache2 --- tcp6 0 0 [::]:www [::]:* LISTEN 6607/apache2 10c10 < tcp6 0 0 [::]:https [::]:* LISTEN 6194/apache2 --- tcp6 0 0 [::]:https [::]:* LISTEN 6607/apache2 Over a period of an hour or three, the parent would change its pid at least once every 20 minutes, without any explanation in the log files or any other hint that anything is going wrong. This is not what I expected. What am I missing?

    - by max
    I know there is a previously asked question, but I still have some doubts so asking again. How do I create a yum repo file? I know that in the /etc/yum.repos.d/ I have to create .repo file. Below is the pattern: 1 [name ] 2 name= 3 baseurl= 4 enabled=1 5 gpgcheck=1 6 gpgkey= Here in the baseurl which link should I give? I'm fully confused about this. How do I get that baseurl link? Can anyone please explain to me clearly? I am using CentOS 6.2.

  • Is there a way to diagnose a tar file when, on extract, files are missing but no errors are given?

    - by ljvillanueva
    I have tar files where I archive about 250 files, each about 80 Mb, without compression. In a few cases tar is only returning some of the files. For example, when doing an extract of the file using: tar -xvf 356.tar I got only 103 files, when it should return 255 files, but tar does not give me an error. Furthermore, the tar archive is 15.8 Gb while the extracted folder is just 6.4 Gb. The tar files were created using tar -cvf 356.tar 356 where 356 is the name of the folder. All the steps where done in the same machines, under Ubuntu 6 and newer. Any ideas if there is a way to recover the files that are not being extracted?

  • 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?

  • 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.

  • What's the best way to forward traffic on a specific port to another machine?

    - by Ankit
    The setup I have is this: [client01] <-A-> [server01] <-B-> [server02] client01 can access port 9300 on server01 (connection A). server01 can access port 9300 on server02 (connection B). What's the best way to make all traffic on port 9300 to server01 go to port 9300 on server02? I can successfully do this with an ssh tunnel from client01 to server01 to server02, but I don't want to have to run ssh on client01. When I ssh from server01 to server02 forwarding port 9300 (ssh -g -L9300:localhost:9300 server02 on server01), it doesn't work -- am I using the wrong command?

  • Permissions issue on Fedora with separate home partition

    - by Tres
    I am running Fedora 12 and I've setup a partition separate from my root partition to keep shared files and home directories. Now, I've been having permission issues where it says the user cannot chdir into their home directory (/files/home/*). Now, I fixed this originally by chmodding / to 0755 and the home directories also to 0755. And yes, the user is the owner:group of their home directory. Now get this, I didn't change a thing, rebooted, everything still works. Great, right? I boot the server up a day later, and now same ol issue. This is a home server that wasn't on at all at any point in between the working state and non-working state. Also, nothing else was modified. Any ideas? Thanks!

  • Is it possible to have environment variables in the path of the working directory : PS1?

    - by mthpvg
    I am on Lubuntu and I am using bash. My PS1 (in .bashrc) is : PS1="\w> " I like it because I need to paste the working directory all the time. The problem is that the path is always very long and since I use terminator I only have half of my screen's width available to display it... it is ugly and annoying. My command prompt looks like that : /this/is/a/very/long/path/that/i/want/to/make/shorter > I'd like to set in my environment variables : $tiavl=/this/is/a/very/long And then I'll get : $tiavl/path/that/i/want/to/make/shorter > The goal is to have something shorter in the command prompt but I still want to be able to copy paste it and do : cd $tiavl/path/that/i/want/to/make/shorter It is a bit like with $HOME : ~/path/that/i/want/to/make/shorter > I know where I am and I can copy paste the ~. Thanks.

  • What Logs / Process Stats to monitor on a Ubuntu FTP server?

    - by Adam Salkin
    I am administering a server with Ubuntu Server which is running pureFTP. So far all is well, but I would like to know what I should be monitoring so that I can spot any potential stability and security issues. I'm not looking for sophisticated software, more an idea of what logs and process statistics are most useful for checking on the health of the system. I'm thinking that I can look at various parameters output from the "ps" command and compare to see if I have things like memory leaks. But I would like to know what experienced admins do. Also, how do I do a disk check so that when I reboot, I don't get a message saying something like "disk not checked for x days, forcing check" which delays the reboot? I assume there is command that I can run as a cron job late at night. How often should it be run? What things should I be looking at to spot intrusion attempts? The only shell access is SSH on a non-standard port through UFW firewall, and I regularly do a grep on auth.log for "Fail" or "Invalid". Is there anything else I should look at? I was logging the firewall (UFW) but I have very few open ports (FTP and SSH on a non standard port) so looking at lists of IP's that have been blocked did not seem useful. Many thanks
