  • Effects of internet connection speeds on server queries

    - by SephMerah
    Can my internet connection significantly effect queries run on phpmyadmin? I am currently 18 down and 30 up. I switched internet connections today and noticed a deep drop in query performance. The query that I am running is SELECT * FROM table. Simple. The table has one row of data. The MySQL server is on the same server as everything else. It is a VPS. Godaddy hosts. I dont have any other information. Centos 6.3 MySQL 5.1 PhpMyAdmin 3.4 Okay used google tools to inspect the XHR going out and coming in and this is what it reported. {"success":true,"message":"<div class=\"success\">Your SQL query has been executed successfully ( Query took 0.0033 sec )<\/div>","sql_query":"<div id=\"result_query\" align=\"\">\n<div class=\"success\">Your SQL query has been executed successfully ( Query took 0.0033 sec ) SNIP..................."}. So apparently my server is fine. The strange thing is though.. The returned XHR comes back exactly as soon as I execute the query on the page. It comes back within less than a second. Why PhpMyadmin does not report the change immediately. I am going to try a re-install.

  • How do I Forward root's email to an external email address?

    - by ErebusBat
    I have a small server (Ubuntu 10.04) at my house and I would like to forward root's email to my gmail hosted domain to get security notifications and what not. I ripped everything out and started from scratch and ran into some other issues. I now have sendmail working in the sense that I can mail [email protected] and get the mail. HOWEVER, adding an address to /root/.forward does not actually forward the message. I get the following in my logs: Dec 22 14:04:37 batcave sendmail[4695]: oBML4bAT004695: to=<root@batcave>, ctladdr=aburns (1000/1000), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30075, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (oBML4bJ9004696 Message accepted for delivery) Dec 22 14:04:39 batcave sm-mta[4698]: STARTTLS=client, relay=[69.145.248.18], version=TLSv1/SSLv3, verify=FAIL, cipher=DES-CBC3-SHA, bits=168/168 Dec 22 14:04:40 batcave sm-mta[4698]: oBML4bJ9004696: to=<[email protected]>, ctladdr=<[email protected]> (1000/1000), delay=00:00:03, xdelay=00:00:03, mailer=relay, pri=120336, relay=[69.145.248.18] [69.145.248.18], dsn=2.0.0, stat=Sent (OK 01/D4-00853-216621D4) You can see where my local sendmail instance accepts it then hands it off to my ISP, but with the wrong address ([email protected]).

  • Change/Deactivate the shell for an amount of users on SUSE Enterprise Server

    - by Manfred Schmidt
    I have a SUSE Server to which ~300 users are connecting. About 100 of them have to be deactivated. I think it would be nice to change their shell to /bin/false either with chsh or with usermod. Do I have to type every command per line, or can I fill out a list of users which can be read from the script? I should mention that all of the 100 users have the same ending in their username. Can I work with wildcards here? e.g. usermod -s /bin/fish *ftpuser chsh -s /sbin/nologin *ftpuser

  • how to use iptables to block the IP of device connected to openwrt router

    - by scola
    I have two routers(A,B).the A connect to internet with IP:192.168.1.1 The openwrt router B connect the lan of A by bridge with static IP:192.168.1.111. I am learning to use iptables to control the devices connected to B(wlan) . I use my phone to connect wifi of B,the phone's IP is IP:192.168.1.100.it can surf the internet normally.

  • Different external ip addresses from different sites

    - by user630286
    My router is ClearOS 6(Centos 6). In my router, I have two external (internet) network connections from two ISP's. The primary connection is eth2 connected to a cable modem and the second one is ppp0 connected to a dsl modem. I have assigned eth2 as the primary connection (with a high metric value). In fact this is done through clearos's multiwan web interface. I have a test in my Nagios to monitor whether the primary connection. This connection is done based on the result of curl ifconfig.me But it seems that ifconfig.me is always giving the ip address of my secondary connection. I tested it through a browser. Yes ifconfig.me gives the secondary internet's(ppp0) ip address. But whatismyipaddress.[com|org] give my primary ip address (eth2). I checked the default route on the router through ip route list 0/0 which also shows the primary connection (eth2) as the default route. The traceroute www.google.com and traceroute ifconfig.me both seems to trace through the primary connection (eth2). As our secondary internet connection has only got a limited download, I don't want to end up having to pay a large sum at the end of the month. Has somebody got an idea why the ifconfig.me shows my secondary address? What is the best way to ensure that my router(and thus the lan) use the right internet connection.

  • Can a named (bind) crash make a server unreachable?

    - by giorgio79
    My server recently became unreachable, and after restart a named error was the last line I found in /var/log/messages before restart: Jun 26 00:15:06 host named[1303]: error (network unreachable) resolving 'dlv.isc.org/DNSKEY/IN': 2001:500:71::29#53 Jun 26 06:38:55 host kernel: imklog 5.8.10, log source = /proc/kmsg started.

  • Is it safe to run Postfix w/o securing it?

    - by Miko
    Does postfix need to be secured before it's safe to run it on a production server? I rely on Monit to notify me if certain processes are down or in trouble. For this purpose and this purpose only, I need postfix on the server so that Monit can send me email notifications. If it's necessary to secure Postfix before deploying it, what are some steps I can take to make it safer?

  • 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?

  • Best practice, or generally best way to set up web-hosting server, permissions, etc.

    - by Jagot
    Hi, I'm about to set up a server upon which a friend and I will be hosting web sites, and I'll be using Debian. I've set up a LAMP solution many times just to using for local testing purposes, but never for actual production use. I was wondering what are the best practices are in terms of setting the server up, in reference specifically to accessing the web root directory. A couple of the options I have seen: Set up a single user account on the server for us both to use and use a virtual host to point to the somewhere in the home directory, e.g. /home/webdev/www. Set each of us up a user account, and grant permissions in some way to /var/www (What would be the best way? Set up a new group?) I want to get this right when I first set this up as there won't be any going back for a while once our first site is up and running. Appreciate any guidance in advance.

  • a brand new FS based on a database without using fuse

    - by Devrim
    hi all, To serve millions of files out of a single directory, being able to connect to a drive from hundreds of endpoints, and for some other reasons (to avoid gluster/nfs/all fs based networking solutions), I want to evaluate the possibility of making a filesystem that's based on a mongodb (or any other). Basically, it works like fusefs, every single file is kept in mongo gridfs. In theory, I do, mount mongodbfs /mountPoint mongodb://localhost then when i say touch /mountPoint/test.txt this file is inserted into mongodb. This FS will also store uid/gid and perms with the file, we can throw hundreds of servers to it, and no useradd will be necessary. I'm not thinking to include all the features of FS, just the ones we need. My question is, how do I start my quest in finding resources, books, links, people, developers who'd help me implement this? at least a proof of concept. Is it feasible? What should I expect as a timeline for such undertaking? Please only think about gazillion small files and folders.

  • How to delete files quicker than rm -rf?

    Is there any way how to delete folder/files quicker than with command rm -rf? It seems my disc is filled with bilions of files (sessions of php5) which were not deleted in cron so I need to delete them manually but it takes hours and it is still not helping reducing the amount. Thank you. My command: rm -rf /var/lib/php5/* Tried also these commands: find /var/lib/php5 -name "sess_*" -exec rm {} \; And perl -e 'chdir "/var/lib/php5/" or die; opendir D, "."; while ($n = readdir D) { unlink $n }'

  • Ubuntu 11.10 firewall/gateway - no client internet access

    I have read many other posts but cannot figure this out. eth0 is my external connected to a Comcast modem.

  • Enabling Shell colours through Putty SSH

    - by Jon
    I have set a number of configurations in my .bashrc file to set the appearance of shell on my Redhat machine. However, when I login as root using Putty, the colours are not shown. I can enable them again by typing 'su', which simply puts me back to root like I was when I logged into putty, but that isn't exaclty ideal. Is there some configuration file or something I can use to enable shell colours when I login with Putty? Thanks

    I have a few 3ware RAID controllers installed in a system. Is there any way to figure out the mapping between the following identifiers, each describing in a way the very same RAID controller? The tw_cli reported controller id (e.g. c0,c1,c2,...) The corresponding device nodes that allow smartctl access via the 3ware driver (e.g. /dev/twa0, /dev/twa1, /dev/twl0) The block device presented to the system representing a RAID unit (/dev/sda, /dev/sdb,...)

  • Advantages of a deployment tool over shell

    - by Jimmy
    Currently I have all of my deployment scripts in shell, which installs about 10 programs and configures them. The way I see it shell is a fantastic tool for this: Modular: Only one program per script, this way I can spread the programs across different servers Simple: Shell scripts are extremely simple and don't need any other software installed One-click: I only have to run the shell script once and everything is setup Agnostic: Most programmers can figure out shell, and don't need to know how to use a specific program. Versioning: Since my code is on github a simple git pull and restart all of supervisor will run my latest code. My question is, with all of these advantages, why is it people are constantly telling me to use a tool such as ansible or chef, and not to use shell.

  • 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.
