  • 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.

  • NTP configuration not recognized?

    - by Eugene S
    I'm trying to configure NTP on my machine but it seems that the parameters I set are not being read by the system. Below is my /etc/ntp.conf file. (I applied the most basic configuration to eliminate other issues) server 10.45.68.47 server 127.0.0.1 After I set the above configuration, I restart the ntpd process by doing the following: service ntpd restart And then I get the following output: Shutting down ntpd: [ OK ] ntpd: Synchronizing with time server: [FAILED] Starting ntpd: [ OK ] Moreover, I can see the following in /var/etc/messages: Apr 2 10:54:07 hsystem1a ntpd[21067]: ntpd exiting on signal 15 Apr 2 10:54:07 hsystem1a ntpdate[21537]: can't find host ntpServer1 Apr 2 10:54:07 hsystem1a ntpdate[21537]: can't find host ntpServer2 Apr 2 10:54:07 hsystem1a ntpdate[21537]: no servers can be used, exiting So it seems that the ntpServer1 and the ntpServer2 are being read from somewhere instead of the IPs I configured in /etc/ntp.conf. NOTE: I done init 6 on the machine just in case. Thanks!

  • SSH rsa key works with external IP not internal IP

    - by Ian
    I am using rackspace cloud hosting. I have 2 servers behind a load balancer. Each server has an external IP and an internal IP. I want to setup a sync job that uses SSH to transfer files. I made an rsa key, and I can successfully SSH from server A into server B, using the external IP of server B, without being prompted for a password. If I try to do the same but use the internal IP, it prompts me for a password. I want to be able to use the key instead of the password. Why is this? Is there something special I have to do during key generation so it works for both IPs? Any help is appreciated.

  • Hung Java JVM failing to respond to kill -3

    - by Hans
    I have a Java VM that is hanging "randomly". I quote the randomly bit, because there is obviously a reason that the VM is hanging, but the hang does not occur periodically. We have the same software running in different customer environments and in those environments the JVM is not hanging. In the process of attempting to troubleshoot the hang the process exists with zero CPU utilization. I then attempt to execute kill -3 and the kill command hangs. No JVM Thread Dump is produced. I have spent time instrumenting the code to periodically log the thread stack traces hoping to catch the JVM in a state that would indicate where the issue lies, but so far this attempt has not born much fruit. Unfortunately I have not been able to reproduce this issue in my lab environment so I am limited by what can be done at the Customer site. The OS's in question are Red Hat Enterprise 5.4 and SUSE 10 running java version 1.6.0_05-b13 Has anyone had this problem? Any ideas on why kill -3 is failing to produce a Java Thread Dump? Thanks!

  • Setting umask for all users

    - by Yarin
    I'm trying to set the default umask to 002 for all users including root on my CentOS box. According to this and other answers, this can be achieved by editing /etc/profile. However the comments at the top of that file say: It's NOT a good idea to change this file unless you know what you are doing. It's much better to create a custom.sh shell script in /etc/profile.d/ to make custom changes to your environment, as this will prevent the need for merging in future updates. So I went ahead and created the following file: /etc/profile.d/myapp.sh with the single line: umask 002 Now, when I create a file logged in as root, the file is born with 664 permissions, the way I had hoped. But files created by my Apache wsgi application, or files created with sudo, still default to 644 permissions... $ touch newfile (as root): Result = 664 (Works) $ sudo touch newfile: Result = 644 (Doesn't work) Files created by Apache wsgi app: Result = 644 (Doesn't work) Files created by Python's RotatingFileHandler: Result = 644 (Doesn't work) Why is this happening, and how can I ensure 664 file permissions system wide, no matter what creates the file? UPDATE: I ended up finding a cleaner solution to this on a per-directory basis using ACLs, which I describe here.

  • Creating rescue / install USB flash disk for CentOS

    - by wwwpanda
    For CentOS installation CDs, you can install OS, as well as booting into "rescue" mode so that you can do a chroot mount on the system partition for problem solving, even the system is installed in hardware RAID drives. How can we create a similar thing but on usb flash drive? I tried to do it with unetbootin, but when booting into the USB, eventually the CentOS setup still requires presence of CDs. Ultimately, I want to use this usb flash drive for remote disaster recovery through say HP iLo remote console / Dell iDrac etc.

  • Can the expect utility handle a case where the process it spawns also spawns a sub process?

    - by davidparks21
    I'm trying to use expect to handle rsync over an ssh shell, but it gets stuck. If I run my rsync command it works (simplified here): It prompts me for my password and copies files to the server: rsync -e ssh -<other_params> If I then enclose that in expect: expect -d -c "spawn rsync -e ssh -<other_params>" -c "expect password:" -c "send mypass\r" It does not execute properly, the program exists and no files are copied. Even the debug mode isn't giving many clues. My best guess is that rsync is spawning the ssh process, and the ssh process is what needs to be interacted with, but send is picking up the rsync process id and sending the input there. Any thoughts?

  • FreeNAS/ZFS/Raid-Z slightly different disks

    - by muskratt
    I'm considering using FreeNAS and "recycling" some of my older 1TB disks. Two are the exact same model Western Digital while another is Seagate and the fourth is Samsung. Typically, since all disks are not equal, I'll create my arrays on a Windows-based server 1GB undersized to prevent a replacement disk not being large enough. Dell is notorious for sending replacement SATA disks of different brand---knock on wood, no problems yet. Since not all drives are created equally and they can vary a few MBs, is there a way to make the the FreeNas/ZFS/Raid-Z function in the same way I do for my Windows-based servers above? Thanks

  • How can I use a keyfile on a removable USB drive for my encrypted root in Debian?

    - by naivem
    Recently set up root encryption with a couple of LVM volumes inside one LUKS volume, and I am just a little confused as to how I would go about getting it to automatically unlock using a keyfile stored on a USB flash drive, I presume I would have to put the drive in the fstab inside my initramfs (if there is one), and add a hook for USB device support. But I digress, essentially, I want to know what I have to do to enable my LUKS volume (containing all of my partitions sans /boot) to unlock using a keyfile stored on a USB flash drive, rather than a manually entered passphrase.

  • fstab and cifs mounting, possible to store authentication information outside of fstab?

    - by tj111
    I am currently using cifs to mount some network shares (that require authentication) in /etc/fstab. It works excellently, but I would like to move the authentication details (username/pass) outside of fstab and be able to chmod it 600 (as fstab can have issues if I were to change its permissions). I was wondering if it is possible to do this (many-user system, don't want these permissions to be viewable by all users). from: //server/foo/bar /mnt/bar cifs username=user,password=pass,r 0 0 to: //server/foo/bar /mnt/bar cifs <link to permissions>,r 0 0 (or something analogous to this). Thanks.

  • How to ask Debian not to check last mount time of its file system?

    - by Landy
    I'm using Debian 6.0.5. To test a feature of my product, I need to modify the system date&time back and forth frequently. Once a time I set the system date back to one month ago, then I reboot the system, and it reported the last mount time of the file system is in the future and enter the maintenance mode automatically. I had to run the fsck to make sure the file system is not broken to boot into Debian. Is there any way to ask Debian stop checking the last mount time of its file system when booting? Thanks.

  • Dual-head monitor system Kubuntu 10.04

    - by andrii
    I have a notebook Asus V6X00V with 1400*1050 monitor(name: LVDS) and Dell Monitor 1920*1080 (VGA-0). I want to have a dual monitor system. At MS Windows everything is working fine. During the Kubuntu installation the Dell and the main notebook monitors have a right resolutions(1920*1080 & 1400*1050). But after some stage it have been changed to the 1152*864 for both. Now the right resolution is only during turning off process and when I am using the console. So it shows that system can use this resolutions. The problem is just in a settings. I am using Size & Orientation - System Settings for setting adjustment. Any option that changes resolution for any monitor or changing position(Absolute, Left Of, Right of and so on) cause the color line noise on the screens. I have tried xrandr: xrandr --output LVDS --mode 1400x1050 --pos 0x0 --output VGA-0 --mode 1920x1080 --right-of LVDS --pos 1400x0 but have received the same result. I have find out that for example the previous version of Randr(1.2, now I have xrandr 1.3) need a xorg.conf file modification to create a big virtual screen, but kubuntu 10.4 don't have xorg.conf and I don't know should I modify xorg for 1.3 version of xrandr or not. Please help me to solve this problem

  • Feeding the kernels entropy source from other machines and/or increasing its maximum size

    - by David Spillett
    We have has a little trouble with a small box that acts as a VPN end-point and mail relay for our network, caused by the available entropy for /dev/random being too low (which causes TLS connection attempts by exim to fail). The machine doesn't do anything else, so the normal feed into the entropy pool (interrupt timings from things like disk access) is not enough. As a quick hack I've set a looping script that reads from /dev/hda at a couple of Mbyte/sec which keeps it topped up. Other than buying a hardware RNG, is there a clean way of piping data for entry from elsewhere, such as a copy of the data our file server uses for its entropy source? I've spotted several tips for using rng-tools to feed it from /dev/urandom on the same machine but that "feels dirty". Also, is it possible to increase the maximum pool size? It currently seems to max out at 3585.

  • Port forwarding not working properly

    - by sudo work
    I'm trying to host a small web server from my home network; however, I have not been able to successfully port forward ports to the local server. My current network topology looks like this: Cable Modem/Router - Secondary Wireless Router - Many computers (including server) The modem/router I'm using is a Cisco (Scientific Atlantic) DPC2100, provided by my ISP. The wireless router that I'm using as the central hub to my home network is a Linksys E3000. The computer being used as a server is running Ubuntu 10.04 Server Edition. The main issue is that I can't access the server remotely, using my WAN IP address. I have port forwarded my wireless router; however, I believe that I need to somehow set my modem to bridge mode. As far as I can tell though, this isn't possible. Here are the various IP address settings: DPC2100 WAN: 69.xxx.xxx.xxx Internal IP: 192.168.100.1 Internal Network: 192.168.7.0 E3000 IP Address: 192.168.7.2 Gateway: 192.168.7.1 Internal IP: 192.168.1.1 Internal Network: 192.168.1.0 Server IP Address: 192.168.1.123 Gateway: 192.168.1.1 Now I can do an nmap at various nodes, and here are the results (from the server): nmap localhost: 22,25,53,80,110,139,143,445,631,993,995,3306,5432,8080 open nmap 192.168.7.2: 22,25,80 (filtered),110,139,445 open (ports I have forwarded in the E3000)* nmap 69.xxx.xxx.xxx: 1720 open *For some reason, I can SSH into the server at 192.168.7.2, but not view the website. Here are also some other settings: /etc/hosts/ 127.0.0.1 localhost 127.0.1.1 servername ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters /etc/apache2/sites-available/default snippet <VirtualHost *:80> DocumentRoot /srv/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> ... </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> ... </Directory> ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> ... </Directory> </VirtualHost> Let me know if you need any other information; some stuff probably slipped my mind.

  • Yum install packages to an alternate directory, without chroot?

    - by Stefan Lasiewski
    I would like to use the Foswiki yum repository to install Foswiki (296 packages). The default installation path is /var/lib/, but I want to install it to an alternate location at /opt/www/. In the future, I still want to use yum to check for and apply updates to the packages. Is it possible to use yum to install packages to an location which is different then the default location provided by RPMs? Does Yum provide anything similar to ./configure --prefix=/usr/local/ or rpm --install --prefix=/opt/local? Yum provides the --installroot option, but that appears to primarily for chroot environments.

  • HTTPS and HTTP issue on server with SSL

    - by Asghar
    I have a site www.example.com for which i purchased SSL cert and installed. And it was working fine, I also have a subdomain with app.example.com which was not on SSL. Both www.example.com and app.example.com are on same IP address. At later we decided to put SSL only on app.frostbox.com and then i configured SSL with app.frostbox.com and it worked fine, Now the issue is that Google is indexing my site as https://www.example.com/ and when users hits the web , Invalid security warning is issued and when user allow security issue they are shown my app.example.com contents. Note: I have my SSL configuration files in /etc/httpd/conf.d/ssl.conf The contents of the ssl.conf are below. NOTE: I tried solutions in .httaccess but none of those worked. Like redirecting 301 redirects etc http://pastebin.com/GCWhpQJq

  • Does lshw list the "factory" speed of a memory module or the effective speed and how to find the former?

    - by Panayiotis Karabassis
    I hope I phrased this correctly. lshw gives: description: DIMM Synchronous 400 MHz (2.5 ns) product: M378B5773CH0-CH9 vendor: Samsung physical id: 0 slot: DIMM0 size: 2GiB width: 64 bits clock: 400MHz (2.5ns) And indeed the memory speed is set is set to 800MHz in the BIOS, which I think makes sense since it is a double rate. On the other hand, Googling strongly suggests that to this product number corresponds the PC3-10600 type, which is 1333MHz, not 800MHz. And this seems to be confirmed in the BIOS, where if I select Auto for memory bus speed, 1333MHz is selected "based on SPD settings". However in the latter case, the computer does not boot, i.e. the kernel panics, complaining that something attempted to kill the Idle process. So, I am I am beginning to suspect that I have been given defective memory, the technician that installed saw this, and lowered the bus speed. Is this a possibility?

  • How can I fix Problems with interlaced video jerking/flicking when playedback on DVD players? (Mixin

    - by Simon P Stevens
    I'm trying to make a DVD and the final DVD jerks when played on standalone DVD players. It seems to play fine on PCs. I think the problem may be to do with interlacing settings when rendering the final output, but I'll outline the whole editing process I have followed in case I've made a mistake somewhere else. Most of the footage comes from a sony handy cam (one of those mini DVD ones) so isn't great quality. It was set to "high quality" (haha) and 16:9 aspect ratio when it was recorded. I copy the files directly from the mini DVDs onto the hard drive and import them into Cinelerra. In Cinelerra I set the format to 25fps, 720x576, RGBA-8bit, 16:9, interlaced bottom fields first. When I've finished the editing, I add a Fields to frames effect (set to bottom first) to each video track. I render to audio and video separately: Audio: AC3, 128kbps Video: YUV4MPEG steam, video pipe settings: ffmpeg -f yuv4mpegpipe -i - -y -target dvd -flags +ilme+ildct mpeg2video % Cinelerra often crashes during the rendering, so I set it to generate a new video file at each label, and combine them using cat when I've got a sucesful render of each one. Once I've combined them, I use mencoder to re-index them: mencoder -forceidx -oac copy -ovc copy merged.m2v -o mergedReIndexed.m2v I combine the audio and video files using ffmpeg: ffmpeg -i AudioFile.ac3 -i VideoFile.m2v -target dvd -flags +ilme+ildct FinalMovie.mpg Then I build the menus with spumux and I create the DVD file system with dvdauthor, and finally I write it do a dvd-r like this: nice -n -20 growisofs -dvd-compat -speed=2 -Z /dev/dvd -dvd-video -V VIDEO ./ && eject /dev/dvd Originally, when I did it the DVD flickered badly, so as suggested in a guide I added the fields to frames effect in cinelerra. Now it doesn't "flicker", but has become "jerky" when there is lots of motion, particularly when the camera is moving, so the whole background moves. This is what I've tried so far: Removed "mpeg2video" from cinelerra video render pipe. Removed +ilme from render pipe. Removed +ildct from render pipe. Removed +ilme from render audio/video rejoin command. Removed +ildct from render audio/video rejoin command. Added -alt to render pipe. Added -alt to render audio/video rejoin command. Tried with and without the frames to fields effect in Cinelerra. and various combinations of the above. I've also tried this: change the Cinelerra fps to 50, use fields to frames (instead of frames to fields), render to an intermediate QTforlinux jpeg video stream, re-importing that back into Cinelerra, adding a frames to fields effect and then rendering that output as normal (@25fps), and I still have the same problem. Has anyone experienced this "jerking" playback before? Can anyone give any suggestions on how to fix it? (Like I say, it plays back fine on a PC, but not on any of the standalone players I've tried)

  • OpenVPN IPv6 over IPv4 tunnel

    - by user66779
    Today I installed OpenVPN 2.3rc2 on both my windows 7 client machine and centos 6 server. This new version of OpenVPN provides full compatibility for IPv6. The Problem: I am currently able to connect to the server (through the IPv4 tunnel) and ping the IPv6 address which is assigned to my client and I can also ping the tun0 interface on the server. However, I cannot browse to any IPv6 websites. My vps provider has given me this: 2607:f840:0044:0022:0000:0000:0000:0000/64 is routed to this server (2607:f840:0:3f:0:0:0:eda). This is ifconfig after setup with OpenVPN running: eth0 Link encap:Ethernet HWaddr 00:16:3E:12:77:54 inet addr:208.111.39.160 Bcast:208.111.39.255 Mask:255.255.255.0 inet6 addr: 2607:f740:0:3f::eda/64 Scope:Global inet6 addr: fe80::216:3eff:fe12:7754/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2317253 errors:0 dropped:7263 overruns:0 frame:0 TX packets:1977414 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1696120096 (1.5 GiB) TX bytes:1735352992 (1.6 GiB) Interrupt:29 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255 inet6 addr: 2607:f740:44:22::1/64 Scope:Global UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:739567 errors:0 dropped:0 overruns:0 frame:0 TX packets:1218240 errors:0 dropped:1542 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:46512557 (44.3 MiB) TX bytes:1559930874 (1.4 GiB) So OpenVPN is sucessfully creating a tun0 interface and assigning clients IPv6 addresses using 2607:f840:44:22::/64. The first client to connect is getting 2607:f840:44:22::1000 and the second 2607:f840:44:22::1001, and so on... plus 1 each time. After connecting as the first client, I can ping from my windows client machine 2607:f740:44:22::1 and 2607:f740:44:22::1000. However, I have no access to IPv6 websites. I believe the problem is that the tun0 IPv6 addressees are not being forwarded to the eth0 interface. This is the firewall running on the server: #!/bin/sh # # iptables configuration script # # Flush all current rules from iptables # iptables -F iptables -t nat -F # # Allow SSH connections on tcp port 22 # iptables -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp --sport 22 -j ACCEPT # # Set access for localhost # iptables -A INPUT -i lo -j ACCEPT # # Accept connections on 1195 for vpn access from client # iptables -A INPUT -i eth0 -p udp --dport 1195 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -p udp --sport 1195 -m state --state ESTABLISHED -j ACCEPT # # Apply forwarding for OpenVPN Tunneling # iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 10.8.0.0/24 -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 209.111.39.160 iptables -A FORWARD -j REJECT # # Enable forwarding # echo 1 > /proc/sys/net/ipv4/ip_forward # # Set default policies for INPUT, FORWARD and OUTPUT chains # iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT # # IPv6 # IP6TABLES=/sbin/ip6tables $IP6TABLES -F INPUT $IP6TABLES -F FORWARD $IP6TABLES -F OUTPUT echo -n "1" >/proc/sys/net/ipv6/conf/all/forwarding echo -n "1" >/proc/sys/net/ipv6/conf/all/proxy_ndp echo -n "0" >/proc/sys/net/ipv6/conf/all/autoconf echo -n "0" >/proc/sys/net/ipv6/conf/all/accept_ra $IP6TABLES -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT $IP6TABLES -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT $IP6TABLES -A INPUT -i eth0 -p icmpv6 -j ACCEPT $IP6TABLES -P INPUT ACCEPT $IP6TABLES -P FORWARD ACCEPT $IP6TABLES -P OUTPUT ACCEPT Server.conf: server-ipv6 2607:f840:44:22::/64 server 10.8.0.0 255.255.255.0 port 1195 proto udp dev tun ca ca.crt cert server.crt key server.key dh dh2048.pem ifconfig-pool-persist ipp.txt push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 208.67.222.222" push "dhcp-option DNS 208.67.220.220" keepalive 10 60 tls-auth ta.key 0 cipher AES-256-CBC comp-lzo user nobody group nobody persist-key persist-tun status openvpn-status.log log-append openvpn.log verb 5 Client.conf: client dev tun nobind keepalive 10 60 hand-window 15 remote 209.111.39.160 1195 udp persist-key persist-tun ca ca.crt key client1.key cert client1.crt remote-cert-tls server tls-auth ta.key 1 comp-lzo verb 3 cipher AES-256-CBC I'm not sure where I am going wrong, it could be the firewall, or something missing from server or client.conf.

I've read the manual for this new version of OpenVPN (parts pertaining to IPv6) and it provides very little info too. Thanks for any help.

  • High frequency, kernel bypass vs tuning kernels?

    - by Keith
    I often hear tales about High Frequency shops using network cards which do kernel bypass. However, I also often hear about them using operating systems where they "tune" the kernel. If they are bypassing the kernel, do they need to tune the kernel? Is it a case of they do both because whilst the network packets will bypass the kernel due to the card, there is still all the other stuff going on which tuning the kernel would help? So in other words, they use both approaches, one is just to speed up network activity and the other makes the OS generally more responsive/faster? I ask because a friend of mine who works within this industry once said they don't really bother with kernel tuning anymore-because they use kernel bypass network cards? This didn't make too much sense as I thought you would always want a faster kernel for all the CPU-offloaded calculations.

  • Determine Location of Inode Usage

    - by Dave Forgac
    I recently installed Munin on a development web server to keep track of system usage. I've noticted that the system's inode usage is climbing by about 7-8% per day even though the disk usage has barely increased at all. I'm guessing something is writing a ton of tiny files but I can't find what / where. I know how to find disk space usage but I can't seem to find a way to summarize inode usage. Is there a good way to determine inode usage by directory so I can locate the source of the usage?

  • How do I start mysqld with options

    - by xiankai
    I need to start up mysqld with command line options as from here: http://dev.mysql.com/doc/refman/5.1/en/server-options.html#option_mysqld_skip-grant-tables I normally do sudo service mysqld start, but passing the option as sudo service mysqld start --skip-grant-tables does not seem to work. Alternatively I have tried starting as a daemon, sudo mysqld_safe --skip-grant-tables & But it seems to terminate too soon: 131101 04:59:57 mysqld_safe Logging to '/var/lib/mysql/vagrant.example.com.err'. 131101 04:59:57 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 131101 05:00:03 mysqld_safe mysqld from pid file /var/lib/mysql/vagrant.example.com.pid ended My last option seems to specify the option in /etc/my.cnf instead, but is there any way to do it via the command line?

  • Explanation of nodev and nosuid in fstab

    - by Ivan Kovacevic
    I see those two options constantly suggested on the web when someone describes how to mount a tmpfs or ramfs. Often also with noexec but I'm specifically interested in nodev and nosuid. I basically hate just blindly repeating what somebody suggested, without real understanding. And since I only see copy/paste instructions on the net regarding this, I ask here. This is from documentation: nodev - Don't interpret block special devices on the filesystem. nosuid - Block the operation of suid, and sgid bits. But I would like a practical explanation what could happen if I leave those two out. Let's say that I have configured tmpfs or ramfs(without these two mentioned options set) that is accessible(read+write) by a specific (non-root)user on the system. What can that user do to harm the system? Excluding the case of consuming all available system memory in case of ramfs
