  • How to connect with MySQL server if it won't connect via the socket?

    - by cwd
    I have an account on a shared server. I have jailshell access and also PhpMyAdmin. I want to run mysql commands via SSH but I'm getting an error: $ mysql -u mySqlUser -p mySqlPw Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' I can connect with PHP and phpMyAdmin, so would it be possible to call mysql from the shell and have it connect via an ip and port instead of the socket? The file /var/lib/mysql/mysql.sock does not exist - maybe that is intentional, and the only thing in /etc/my.cnf is [mysqld] skip-innodb More Info I don't have access to change system settings. I did a search in /var for mysql.sock but found nothing. However, phpMyAdmin might be connecting via a socket somehow: Really it would just be great if I could connect via IP. Also tried these two syntaxes: $ mysql -u mySqlUser -p mySqlPw -h localhost $ mysql -u mySqlUser -p mySqlPw -h localhost -P 3306 Both with the same result: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

  • Easier way to create floppy disk images?

    - by Bryan
    I'm using Vyatta routers with KVM and want to attach a floppy drive with a config file for Vyatta when I boot the image. I'll be doing this over and over again, and as such am looking for an automated way of creating the floppy images. Right now, I'm doing the following: Create floppy image with qemu-img create Format floppy image with mkdosfs Mount floppy image with mount -t fat /tmp/floppy.img /media/floppy Populate floppy image with cp -r /tmp/configs/ /media/floppy/ Unmount floppy image with umount /media/floppy Save floppy image with mv /tmp/floppy.img ~/floppies/ Any chance there's an easier way to do this?! Perhaps a shortcut application that I can give a directory to and it will do all this for me w/out having to mount the image?

  • How to access MySQL when I delete the root user on openSUSE 11?

    - by Negin Nicki
    Unfortunately I deleted MySQL users with the command delete from mysql.user and now I can't access MySQL. I tried looking at MySQL - ERROR 1045 - Access denied, but it is not proper for me because I don't have any user for MySQL. I uninstalled and reinstalled MySQL but I can't access MySQL. What should I do? I wanted to have phpMyAdmin without login and I ruined the whole thing. After uninstalling and having no result, I tried to delete the directories of MySQL and again installing them but again no result and now I have this error: Error 2002:can't connect to local mysql server through socket /var/lib/mysql/mysql.sock I don't have any user to reset the password of, but if I have by reinstalling which I don't know how to connect to MySQL. I tried MySQL -u root I tried MySQL I tried mysqld-safe and etc in the link

  • How to limit reverse SSH tunelling ports?

    - by funktku
    We have a public server which accepts SSH connections from multiple clients behind firewalls. Each of these clients create a Reverse SSH tunnel by using the ssh -R command from their web servers at port 80 to our public server. The destination port(at the client side) of the Reverse SSH Tunnel is 80 and the source port(at public server side) depends on the user. We are planning on maintaining a map of port addresses for each user. For example, client A would tunnel their web server at port 80 to our port 8000; client B from 80 to 8001; client C from 80 to 8002. Client A: ssh -R 8000:internal.webserver:80 clienta@publicserver Client B: ssh -R 8001:internal.webserver:80 clientb@publicserver Client C: ssh -R 8002:internal.webserver:80 clientc@publicserver Basically, what we are trying to do is bind each user with a port and not allow them to tunnel to any other ports. If we were using the forward tunneling feature of SSH with ssh -L, we could permit which port to be tunneled by using the permitopen=host:port configuration. However, there is no equivalent for reverse SSH tunnel. Is there a way of restricting reverse tunneling ports per user?

  • Over writing output to a text file

  • How to interpret IOZone results?

    - by homer5439
    Here are the resuts of running IOZone on an ext3 filesystem on an LVM volume residing on a SAN LUN (it was ran with 5 parallel processes). "Throughput report Y-axis is type of test X-axis is number of processes" "Record size = 4 Kbytes " "Output is in Kbytes/sec" " Initial write " 81628.55 " Rewrite " 83354.72 " Read " 115595.02 " Re-read " 119306.09 " Reverse Read " 47684.20 " Stride read " 10011.09 " Random read " 16751.27 " Mixed workload " 5659.77 " Random write " 1661.85 " Pwrite " 36030.83 Now this is all nice and dandy, but my question is: how do I know whether the values are as good as they could be or there is something to tweak (and if so, what?) The actual usage I will have for that Logical Volume is to act as virtual disk for a VM.

  • SSD suddenly full

    - by Daniel
    Today the hard drive of our server was suddenly full. The disk usage always stayed around 50 % in the weeks and months before (old data is regularly expunged from the server). I deleted 10 GB of files in /tmp, which strangely freed 51 GB. Here is what I did: root@***:~# df -h Dateisystem Size Used Avail Use% Eingehängt auf /dev/sda3 139G 137G 0 100% / tmpfs 3,9G 0 3,9G 0% /lib/init/rw udev 3,9G 116K 3,9G 1% /dev tmpfs 3,9G 0 3,9G 0% /dev/shm /dev/sda1 985M 25M 910M 3% /boot root@***:/var# du -hs * 3,3M backups 438M cache 9,4G lib 4,0K local 12K lock 76M log 24K mail 4,0K opt 88K run 184K spool 10G tmp 12K www root@***:/var/tmp# find -type f -print0 | xargs -0 rm root@***:/var/tmp# df -h Dateisystem Size Used Avail Use% Eingehängt auf /dev/sda3 139G 81G 51G 62% / tmpfs 3,9G 0 3,9G 0% /lib/init/rw udev 3,9G 116K 3,9G 1% /dev tmpfs 3,9G 0 3,9G 0% /dev/shm /dev/sda1 985M 25M 910M 3% /boot Any explanation as to why deleting 10 GB in /tmp gave me back 51 GB on the disk? Could this point to an SSD failure? Are there any tools for Debian to test SSD health? I already have checked syslog. The first entry relating to this incidient is a mysql message: 1:22:02 [ERROR] /usr/sbin/mysqld: Disk is full writing... So I have absolutely no idea what caused this.

  • Debian: video problems with VLC

    - by kemp
    I have a problem playing AVI divx files with VLC. Yesterday upon start VLC showed an error message complaining about divx codecs and refused to proceed. Today the player starts but the video is squashed horizontally (it occupies roughly 1/4th of the VLC window which is for the other part black). I'm on an updated testing system, and before yesterday VLC was playing fine. In the meantime - after a recent dist-upgrade - I cannot run X with proprietary ATI drivers anymore, I have to use the FOSS radeonhd ones instead. I don't know if that's related but I thought it could be worth mentioning (and by the way if anyone has suggestions about this problem too, that'd be very much appreciated). How can I fix VLC's problem?

  • How can I automatically convert all source code files in a folder (recursively) to a single PDF with syntax highlighting?

    - by Bentley4
    I would like to convert source code of a few projects to one printable file to save on a usb and print out easily later. How can I do that? Edit First off I want to clarify that I only want to print the non-hidden files and directories(so no contents of .git e.g.). To get a list of all non-hidden files in non-hidden directories in the current directory you can run the find . -type f ! -regex ".*/\..*" ! -name ".*" command as seen as the answer in this thread. As suggested in that same thread I tried making a pdf file of the files by using the command find . -type f ! -regex ".*/\..*" ! -name ".*" ! -empty -print0 | xargs -0 a2ps -1 --delegate no -P pdf but unfortunately the resulting pdf file is a complete mess.

  • Apache - The name

    - by Josh
    I am working on a migration to a newer virtualized server. The old one has Apache 2.2.4 according to the old servers phpinfo(). The new one with the most up to date has 2.2.3 . How can this be assuming no trickery is involved? The old one is years old. Alot of the guides I reference use apache2 in folders names and many of the conventions. The newest version of things, as I understand it is called httpd. Did apache change the name from what it originally was? (i.e. break the web server component into its own project called httpd, I realize the original daemon was probably still called httpd)

    - by Camran
    How is backup done on ubuntu servers? I have a server (Ubuntu 9.10) which has apache2 installed, php5, mysql etc... The website is a classifieds website where all classifieds are stored in mysql and Solr. I need to backup this server with all information to be able to fully restore it if something goes wrong. How should I start? Is it an automated task, or will I do backups manually? (prefer manually) Thanks

  • Trying to make changes to the size of the events buffer in prelude-ids auditd plugin

    - by tharris
    I am running systems using the prelude-ids plugin for auditd. When the manager is up every thing works fine however I have a requirement that when the clients can't talk to the manager they should store no more than 250MB of messages, and when they hit that point they should start deleting the oldest events. All I can find is that audispd can be set to an overflow action of ignore,syslog,suspend,single, and halt none of which meet my requirement, and several of which I really cannot use. Does anyone know a way to do this? I know the events get stored in /var/spool/prelude/auditd/global, but I can't find anything about configuring how things are stored here. There are usually several files in the global directory but only 2 of them ever go above 0 in size, data0 and data0.journal.

  • What are working xorg.conf settings for using a Matrox TripleHead2Go @ 5040x1050?

    I'm trying to configure xorg.conf to correctly set the resolution of my screens. I'm using a matrox triplehead, so the monitor is a single 5040x1050 screen.

  • OSS Router firmwares

    - by Cherian
    DD-WRT, Open WRT , Tomato or Third-party firmware projects ? What are the compelling reasons to choose between these? I used to be a great DD-WRT fan until I realized that the author was deceiving users by publishing it as a OSS, but made it very cumbersome to download the source and change it (requires you to download GB’s of source files) .Also their bandwidth monitoring feature was part of the paid version, which IMHO is a killer. Having said that, DD-WRT just worked. And I think that’s great..

  • Log ports opened by an application

    - by Simon A. Eugster
    I'm searching for something like: tcpdump -p PID # But tcpdump does not know the PID or lsof -i --continuous # But lsof just runs and exits, no «live logging» to log which connections an application opens. In my case, I want to find out to which port git connects when committing. This happens in a fraction of a second, so I cannot use lsof. If there is a lot of traffic, filtering by PID or process name would be useful.

  • openvpn problem

    - by Jared Voronik
    I have a problem with openvpn. I have already setup openvpn sucessfully on some other servers in the past (basic configuration, nothing special). On this server, I used the same config file, but for setting up nat iptables -t nat -A POSTROUTING -s 10.4.0.0/24 -o eth0 -j MASQUERADE doesn't work. It gives error: iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. How do I fix this error? Also, if I can't fix this error, can I do bridging instead of routing? I have only 1 interface, and I can connect to remote server only via ssh (and need to avoid reboots if at all possible) so if briding means a whole ethernet card has to be devoted to the openvpn (and no other servers) then briding is out, otherwise I can use briding. Do you know of a simple, step by step guide to configure openvpn briding (just simple openvpn server and clients that can access internet through vpn server, nothing fancy)?

  • How to mount remote sambe from local host with multiple groups ?

    - by Dragos
    I am using mount.cifs to mount a remote samba share (both client and server are Ubuntu server 8.04) like this: mount.cifs //sambaserver/samba /mountpath -o credentials=/path/.credentials,uid=someuser,gid=1000 `$ cat .credentials username=user password=password I mounted a user from local system with username and password with mount.cifs but the problem is that the user is part of multiple groups on the remote system and with mount.cifs I can only specify one gid. Is there a way to specify all the gids that the remote user has ? Is there a way to: 1) Mount the remote samba with multiple groups on the local system ? 2) Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs. Other solutions would be: nautilus sftp:// which runs through gvfs but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal. An the last solution would be nfs but that means that I have to synchronize the uids and gids on the local system with the ones from the server.

  • How can I measure actual memory usage from my running processes?

    - by NullUser
    I have two servers, server1 and server2. Both of them are identical HP blades, running the exact same OS (RHEL 5.5). Here's the output of free for both of them: ### server1: total used free shared buffers cached Mem: 8017848 2746596 5271252 0 212772 1768800 -/+ buffers/cache: 765024 7252824 Swap: 14188536 0 14188536 ### server2: total used free shared buffers cached Mem: 8017848 4494836 3523012 0 212724 3136568 -/+ buffers/cache: 1145544 6872304 Swap: 14188536 0 14188536 If I understand correctly, server2 is using significantly more memory for disk I/O caching, which still counts as memory used. But both are running the same OS and if I remember correctly, I configured both with the same parameters when they were installed. I did a diff on /etc/sysctl.conf and they are identical. The problem is, I am collecting memory usage and other metrics over a period of time, (eg: vmstat, iostat, etc.) while a load is generated on the system. The memory used for caching is throwing off my calculations on the results. How can I measure actual memory usage from my running processes, rather than system usage? Is used - (buffers + cached) a valid way to measure this?
