• Sticky sessions not sticky on coldfusion cluster

  - by GreatSeaSpider

  we're trying to deploy a legacy coldfusion site onto a new CF8 cluster. The cluster consists of three cf instances running under JRUN4 on a single windows 2008 server. I've got the cluster set to not replicate sessions, and sticky sessions turned on. each instance is set to use J2EE session variables. The application tag for the site has: sessionmanagement="Yes" setclientcookies="Yes" setdomaincookies="Yes" when each instance starts... no errors are reported in the instance log and they join the cluster without any issues. though the intances do have: 16/10 08:31:25 info SessionReplicationService successfully joined a JINI lookup service (assigned JINI-ID .....) and 16/10 08:31:25 info Clusterable service SessionReplicationService discovered a SessionReplicationService peer on a JRun server named "xxxx" on host xxxx which is interesting since session replication is definately off, is the SessionReplicationService responsible for sticky sessions aswell? thats enough background, the problem is that the sticky sessions appear to simply not work, each request is bounced to a different instance, and it seems as if the sessions are being lost on each instance anyways? As soon as the cluster is down to a single instance, the web app works exactly as expected and the sessions seem fine. has anybody got any ideas for me? i've been trawling the web and I cant seem to find any answers.

• Poor NFS Performance: OpenFiler

  - by Safin09

  Good Day Everyone, I have an issue with OpenFiler, a Linux-based operating that converts a computer system into a SAN/NAS appliance. Here is the problem. In my environment we have two Netapp Storevault 500 appliances that I normally perform backups to a NFS share. There are two backup cronjobs that use ghettoVCB to backup two groups of VM's. One group is a pool of 3 VMs. This takes 13 mins to complete. A second job that backups a pool of 5 VMs to a 2nd Storevault appliance which takes 2 hours. We then installed Openfiler on a old server that has 2 core Xeon processors. There is a software RAID 5 process in place. When performing the same backups to a NFS Openfiler share, the first backup job, which takes 13 mins, takes around 4 hours. The second backup job, which takes 2 hours, takes almost 10 hours to complete. This is unacceptable!!!! Especially considering the strain placed on the host ESX Server. I assumed that because of the software RAID 5, the overhead on the CPU explained the long backup times. I then installed Openfiler on a 2nd server, an IBM x306 machine which has a P4 Intel processor. This time no software RAID or any RAID at all. A single 750GB hard drive that contained the OS and the rest of the disk uses to backup VMs to a NFS share. I performed the first backup job of the pool of 3 VMs. This time the backup job took 1 and 1/2 hours to complete instead of 13 mins!!!!!!!!!! Is Openfiler simply poor at being an NFS Server!!!!!!!!!!!!! Has anyone else had these issues with Openfiler?

• Apache2/Shibboleth TCP connections stuck in CLOSE_WAIT

  - by RJT

  I run an Apache2 server which uses the Shibboleth daemon (shibd) as federated authentication module. Certain server connections using Shibboleth seem to stick permanently in CLOSE_WAIT state. tcp 38 0 blah.blah:57346 shib.server.:8443 CLOSE_WAIT tcp 38 0 blah.blah:45601 shib.server2:8443 CLOSE_WAIT tcp 38 0 blah.blah:41737 shib.server3:5057 CLOSE_WAIT From what I can find out, CLOSE_WAIT means that when the remote server disconnects, the local application is failing to close the connection, as it should. I suspect shibd is responsible somehow. Needless to say, if enough CLOSE_WAIT connections accumulate, I have a problem. Trying to get rid of the CLOSE_WAIT connections by simply using /etc/init.d/networking restart does not work. In fact networking seems to refuse to close down and restart, and I get a SIOCADDRT: File exists error (ie networking is trying to start without having stopped first). Same problem with ifup -a So I have two questions - one may be easy, and one harder. What's a good way to force networking to restart, and force whatever connections are stuck in CLOSE_WAIT to clear? Any ideas about how to fix shibboleth and force shibd module to behave?

• Can I change the user id of a user on one Linux server to match another server in /etc/passwd?

  - by user76177

  I have a Rails application that is on a virtual machine (RHEL 6) and it's database is on dedicated hardware (also RHEL 6). The app server has an NFS directory from the db server mounted and accessible. It needs to write images to that server that are uploaded via the app. Background processes on the db server need to read and write to the same directory, as they perform resizing operations on the uploaded files. Right now none of this is working, because the user ids are different between the two systems. I only need this to work for this one application, so it is way too much overhead to put an LDAP system in place. Can I simply change the user id of this one user in one of the systems, or will that cause mass chaos? UPDATE: The fix worked, at least on local devices. Unfortunately the device I have mounted to the main db server still thinks my user id is 502 instead of 506. Do I need to remount that device, or is there an NFS daemon I can stop and restart to refresh it?

• Where should CentOS users get /usr/share/virtio-win/drivers for virt-v2v?

  - by Philip Durbin

  I need to migrate a number of virtual machines from VMware ESX to CentOS 6 KVM hypervisors. Ultimately, I wrote an RPM spec file that solved my problem at https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec but I'm not sure if there's another RPM in base CentOS or EPEL (something standard) I should be using instead. Originally, I was getting this "No root device found in this operating system image" error when attemting to migrate a Window 2008 VM. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm virt-v2v: No root device found in this operating system image. . . . but I solved this with a simply yum install libguestfs-winsupport since the docs say: If you attempt to convert a virtual machine using NTFS without the libguestfs-winsupport package installed, the conversion will fail. Next I got an error about missing drivers for Windows 2008. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/amd64/Win2008 . . . and I resolved this by grabbing an iso from Fedora at http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ as recommended by http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers and building an RPM from it with this spec file: https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec Now, virt-v2v exits without error: [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: my-vm configured with virtio drivers. [root@kvm01b ~]# Now, my question is, rather that the virtio-win RPM from the spec file I wrote, is there some other more standard RPM in base CentOS or EPEL that will resolve the error above? Here's a bit more detail about my setup: [root@kvm01b ~]# cat /etc/redhat-release CentOS release 6.2 (Final) [root@kvm01b ~]# rpm -q virt-v2v virt-v2v-0.8.3-5.el6.x86_64 See also Bug 605334 – VirtIO driver for windows does not show specific OS: Windows 7, Windows 2003

• itunes iphone sync stuck on "Waiting for items to copy"

  - by lindes

  superuser crowd, I've found a number of threads about this, but have yet to find a satisfactory answer. Perhaps I'll have better luck on this site?? I hope so... I'm having a problem with iTunes where syncing my iPhone ends up seeming to basically finish, but it says "Waiting for items to copy" after everything else, and just stays there for... well, a very long time, if I let it. Oh, and I'm not sure this is always the case, but at the moment, it's doing this while "Syncing Genius Data to [my iPhone] (Step 8 of 8)". If I click the little x in iTunes, it then gets stuck on "Canceling sync", for an equally indefinite sort of period. If I simply unplug the phone, everything seems to be synced and happy, but the next time I sync, it happens again. I presume this is a bug of some sort on Apple's part, but it seems like people have found workarounds... I'm just having trouble tracking one down that (a) is well described enough that I can actually follow it, (b) has enough detail that I can do it without losing data (i.e. tells me pathnames that I might want to copy first, or the like, before telling me to remove something) (note: see also point (a) -- I can't remove it if it's telling me to remove something that I don't know where it is!), and (c) otherwise seems sane. I'm hoping that here perhaps I'll get better luck -- with either a workaround, and/or debugging tips for figuring out how to find myself a workaround. Note: I'm busy with some other things at the moment, but can try to add some additional information later, if necessary.

• Setting up Apache 2.2 + FastCGI + SuExec + PHP-FPM on Centos 6

  - by mr1031011

  I'm trying to follow this very detailed instruction here, I simply changed from www-data user to apache user, and is using /var/www/hosts/sitename/public_html instead of /home/user/public_html However, I spent the whole day trying to figure out why the php file content is displayed without being parsed correctly. I just cant's seem to figure this out. Below is my current config: /etc/httpd/conf.d/fastcgi.conf User apache Group apache LoadModule fastcgi_module modules/mod_fastcgi.so # dir for IPC socket files FastCgiIpcDir /var/run/mod_fastcgi # wrap all fastcgi script calls in suexec FastCgiWrapper On # global FastCgiConfig can be overridden by FastCgiServer options in vhost config FastCgiConfig -idle-timeout 20 -maxClassProcesses 1 # sample PHP config # see /usr/share/doc/mod_fastcgi-2.4.6 for php-wrapper script # don't forget to disable mod_php in /etc/httpd/conf.d/php.conf! # # to enable privilege separation, add a "SuexecUserGroup" directive # and chown the php-wrapper script and parent directory accordingly # see also http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/ # FastCgiServer /var/www/www-data/php5-fcgi #AddType application/x-httpd-php .php AddHandler php-fcgi .php Action php-fcgi /fcgi-bin/php5-fcgi Alias /fcgi-bin/ /var/www/www-data/ #FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -socket /tmp/php5-fpm.sock -pass-header Authorization #DirectoryIndex index.php # <Location /fcgi-bin/> # Order Deny,Allow # Deny from All # Allow from env=REDIRECT_STATUS SetHandler fcgid-script Options +ExecCGI </Location> /etc/httpd/conf.d/vhost.conf <VirtualHost> DirectoryIndex index.php index.html index.shtml index.cgi SuexecUserGroup www.mysite.com mygroup Alias /fcgi-bin/ /var/www/www-data/www.mysite.com/ DocumentRoot /var/www/hosts/mysite.com/w/w/w/www/ <Directory /var/www/hosts/mysite.com/w/w/w/www/> Options -Indexes FollowSymLinks AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> PS: 1. Also, with PHP5.5, do I even need FPM or is it already included? 2. I'm using mod_fastcgi, not sure if this is the problem and it I should switch to mod_fcgid? There seems to be conflicting records on the internet considering which one is better. I have many virtual hosts running on the machine and hope to be able to provide each user with their own opcache

• Set default MySQL connect charset for PHP (in RHEL)?

  - by Martijn Heemels

  We're running a hundred or so legacy PHP websites on an older server which runs Gentoo Linux. When these sites were built latin1 was still the common charset, both in PHP and MySQL. To make sure those older sites used latin1 by default, while still allowing newer sites to use utf8 (our current standard), we set the default connect charset in php.ini: mysql.connect_charset = latin1 mysqli.connect_charset = latin1 pdo_mysql.connect_charset = latin1 Specific more modern sites could override this in their bootstrapping code with: <?php mysql_set_charset("utf8", $dsn ); ...and all was well. Now the server is overloaded and we're no longer with that hoster, so we're moving all these sites to a faster server at our standard hoster, which uses RHEL 5 as their OS of choice. In setting up this new server I discover to my surprise that the *.connect_charset directives are a Gentoo specific patch to PHP, and RHEL's version of PHP doesn't recognize them! Now how do I set PHP to connect to MySQL with the latin1 charset? I thought about setting a default in my.cnf but would prefer not to force every app and client to default to latin1. Our policy is to use utf8, and we'd like to restrict the exception to PHP only. Also, converting every legacy site to properly use utf8 is not doable since many are of the touch 'm and you break 'm kind. We simply don't have the time to go fix them all. How would I set a default mysql/mysqli/pdo_mysql connection charset to latin1 for PHP, while still allowing individual scripts to override this to utf8 with mysql_set_charset()?

• Server Performance

  - by sb12

  I know very little about performance tuning of servers etc... so i thought i'd put this up here as i start some research on it, just to get some direction. I am in the process of migrating from my old server to a new one - both are 64 bit machines. One is a few years old, the other brand new (PowerEdge R410). The old server spec is: 2 cpus, 3.4GHz Pentiums, 8G of RAM, Fedora 11 currently installed The new server spec is: 16 cpus, 3.2 GHz Xeon, 16G of RAM, CentOS 6.2 installed. Also RAID10 is on the new server - no RAID on the old one. Both servers currently have the same database (MySQL) with the same data migrated. I wrote a Perl script that simply steps through each row of a table in the database (about 18000 rows) and updates a value in that row. Every row in the table is updated. Out of curiosity i ran this perl script on both machines, just to see how the new server would perform vs. the old one, and it produced interesting results: The old server was twice as fast as the new one to complete. Looking at the database, both are configured exactly the same (the new one being a dump of the old one...)... Anyone any ideas why this would be given the hardware gap between both? As i said i'm about to start some digging, but thought i'd put this up here to maybe get some good direction.... Many thanks in advance..

• Windows Terminal Server: occasional memory violation for applications

  - by syneticon-dj

  On a virtualized (ESXi 4.1) Windows Server 2008 SP2 32-bit machine which is used as a terminal server, I occasionally (approximately 1-3 event log entries a day) see applications fail with an 0xc0000005 error - apparently a memory access violation. The problem seems quite random and only badly reproducable - applications may run for hours, fail with 0xc0000005 and restart quite fine or just throw the access violation at startup and start flawlessly at the second attempt. The names of executables, modules and offset addresses vary, although a single executable tends to fail with same modules and the same memory offset addresses (like "OUTLOOK.EXE" repeatedly failing on module "olmapi32.dll" with the offset "0x00044b7a") - even across multiple user's logons and with several days passing without a single failure inbetween. The offset addresses seem to change across reboots, however. Only selective executables seem affected by the problem, although I may simply not be seeing a sufficient number of application runs from the other ones. I first suspected a possible problem with the physical machine's RAM, but ruled this out as a rather unlikely cause - the memory comes with ECC and I've already moved the virtual machine across several times, without any perceptable change. I've seen that DEP was enabled in "OptOut" mode on this machine: C:\Users\administrator>wmic OS Get DataExecutionPrevention_SupportPolicy DataExecutionPrevention_SupportPolicy 3 and tried changing the policy to OptIn via startup options: bcdedit.exe /set {current} nx OptIn but have yet to see any effect - I also would expect Outlook 12 or Adobe Reader 9 (both affected applications) to play well with DEP. Any other ideas why the apps may be failing?

• Solaris 10 zlogin logs in, logs out immediately

  - by Spelevink

  On a SPARC v445 running Solaris 10 9/10, had to rebuild rpool and reattached the three existing mirrored zpools on the other existing disks, with their zfs filesystems and NG zones intact. The zones have been configured with zonecfg -z ZONENAME create etc. ... and are now online using zoneadm -z ZONENAME attach -U then simply booting after being in installed state, but I cannot zlogin to any of the zones except one. It shows that I am logged in, then a blank line, then immediately logged out again. When I try to login using zlogin -C ZONENAME I cannot; the error message is: May 15 15:43:46 <hostname> login: open_module: stat(/usr/lib/security/pam_mkhomedir.so.1) failed: no such file or directory. May 15 15:43:46 <hostname> login: load_modules: cannot open module /usr/lib/security/pam_mkhomedir.so.1 But /usr/lib/pam_mkhomedir.so.1 does not exist, and it does not exist on my other servers, but those zones are accessible using zlogin. I can only zlogin to the zones with zlogin -S ZONENAME. What to do next? Thank you.

• EEE PC Keyboard malfunctioning - Ctrl key "sticks" after 10 seconds

  - by DWilliams

  I was given a EEE PC belonging to a friend of a friend to fix. The keyboard did not appear to work at all. I spent a while testing out various things, blowing the keyboard out, checking for damage, and so on. Nothing appeared to be physically wrong. At first I noticed that the keyboard appeared to work just fine for 10 seconds (on average, sometimes more sometimes less) after being powered on. It had been restored to the factory default xandros installation with no user set up, so I couldn't get in to mess with things since I couldn't type to make a user. I made an ubuntu live USB to boot it from, and managed to get the boot order changed to boot from USB in the ~10 seconds of working keyboard I had (I don't think I've ever had to rush around BIOS menus that quickly). After I got Ubuntu up on it, I played around a bit more and determined that apparently the ctrl key is stuck down (not literally, but it's on all the time). If I open gedit, pressing the "o" key brings the open dialog, "s" opens the save dialog, and all other behaviour you would expect to see if you were holding down the control key. The only exception that I noticed is the "9" and "0" keys. They function normally. Figuring that out I made a xandros user with a name/password consisting of 9's and 0's. I couldn't find any options in Xandros that could potentially be helpful. I'm not familiar with EEE PCs. Is it safe to assume that the keyboard is simply dead or could there be another problem? I don't want to purchase another keyboard for him if that isn't going to fix the problem. The netbook doesn't show any obvious signs of damage but the owner is a biker and very often has it with him on the road so it's been subjected to a good bit of vibration.

• Loading the 'pktgen' module on Ubuntu Server

  - by StackedCrooked

  I would like to enable and use the pktgen module on Ubuntu Server. I have enabed the module by adding a line containing 'pktgen' to the /etc/modules file. After rebooting it seems that the module is successfully loaded because the directory /proc/net/pktgen exists.

When I try this manually it fails as well: root@ubuntu:~# cd /proc/net/pktgen/ root@ubuntu:/proc/net/pktgen# touch eth4 touch: cannot touch `eth4': No such file or directory Can anyone help me make it work? I'm using Ubuntu version: 2.6.32-21-server. Fixed I apologize for keeping this post not up to date. I was able to fix it. If I remember well the cause of the error was that eth4 did not exist, or did not have the 'online' status. Anyway, it is fixed now.

• Broken Creative DTT3500 Digital

  - by djechelon

  Hello, many years ago I bought a Creative DTT3500 Digital surround speakers system. It's been a while since my home theatre started behaving strange. During the past 6 months, I have noticed that the amplifier needed some time before correctly playing digital audio. Until a couple of weeks ago, it needed up to 5 minutes of very noisy "warm up" before playing an "almost" clear audio. Today, I found that even using the analog input (completely disabling digital inputs) the noise persists. Powering off and on the speakers doesn't work. Now, it's reasonable that after almost 10 years, the amplifier got broken. My problem is that I can't simply replace the speakers with another kit from another brand, since 2 speakers in my room are placed in the back wall, with coaxial cables going under the floor but not completely inside a single tube. I mean, I have coaxial extension cables starting from the DTT3500 amplifier, going into the wall, then under the floor in a plastic cable tube, then exiting the tube (still under the floor), connecting to the male coaxial connector of the original cable supplied by Creative, and continuing up to the point close to my bed where the speakers are. I could replace the speakers **only as soon as the new speakers have the same coaxial to bi-polar cables that Creative ships with DTT3500 Another option might be "repairing the amplifier", but I don't know if it's feasible, what should I or a technician look for in the amplifier, and how much would it cost (is it worth to repair or buy a new kit considering the problem above? What do you suggest me to do, basing on the above observation? Thank you.

• Why does nmap ping scan over a VPN link return all hosts alive?

• Multiple public IPs through DD-WRT without 1-to-1 NAT

  - by Stephen Touset

  I've done a search here and wasn't able to find anything relevant to my situation. I apologize in advance if I've missed an existing post on the topic. Our ISP has provided us with 6 static IP addresses. We are currently using two of them (plus one for the Comcast-provided router). One of the static addresses routes to our internal network, and the other goes to our VOIP phone system. Unfortunately, the Comcast machine doesn't support QoS, so our VOIP calls have been choppy. We plan to put the Comcast-provided router into bridge mode and replace it with an ASUS RT-N16 running DD-WRT. However, I'm unsure how to set up DD-WRT to function similarly to our existing Comcast router. The Comcast router's WAN IP is the first of our static IP addresses. We did not need to provide an internal LAN IP address — simply connecting machines that use our other public addresses to the LAN ports on the Comcast router is enough for it to route between the connected machines and our internet connection. Is there a way to do a similar setup through the DD-WRT? Thanks in advance.

• Is there any way to customize the Windows 7 taskbar auto-hide behavior? Delay activation? Timer?

  - by calbar

  I'm becoming increasingly frustrated with the way Windows 7 handles showing a hidden taskbar. It's incredibly over-eager to pop out and obscure what I'm really trying to interact with, requiring me to move the mouse away, wait for it to auto-hide again, then resume what I was doing but more deliberately. After closely examining the behavior, it appears that a hidden taskbar "peeks out" from the edge by 2 or 3 pixels, and slowly moving your mouse into this area activates it; you don't even need to touch the edge of the screen. I would love it if there was a way to customize or change this behavior. Ideally, the taskbar would only pop out if you are actively "pushing" the edge of the screen it is hidden on. So activation only occurs once you've reached the screens edge and continue to move the mouse past a customizable threshold. Alternatively, a simple activation delay would suffice as well. So only if the mouse remains in that 2-3 pixel area (a.k.a. on the taskbar) for greater than a customizable amount of time does it pop out again. This would only be a fraction of a second. Often times the cursor simply "careens" off the edge of the screen while trying to focus on something nearby. Anyway, if there are any registry settings or utilities that can achieve either of these effects, that would be great! Thanks for your help.

• Ntop monitoring - Hosts visible with no SPAN/mirroring

  - by Cory J

  I am attempting to use ntop to monitor traffic over a Cisco Catalyst switch. I was assuming that in order to see any of the traffic, I'd have to use monitor, as described here: http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml. Howver, before I did anything on the switch, I simply plugged my ntop server in and fired up ntop. To my suprise, I instantly see 3+ pages of hosts, and thousands of packets. How is ntop seeing this? I have verified that no monitoring exists on the switch (run as en): cs1.pvdc#show monitor No SPAN configuration is present in the system. My ntop server is Ubuntu 8.04, I haven't done ANY configuration, I just installed the ntop package. This is also a fresh Ubuntu install. Is there anything else on my switch besides "monitor" that might cause my switch to mirror all its traffic like this? I've tried plugging ntop into different ports with the same results. UPDATE: It appears to be more then just broadcast traffic showing up in ntop, for example, I can see when my IPs have talked to the DNS server or generated HTTP traffic. If my switch is misconfigured, can anyone point me in the right direction towards rectify this? Not a Cisco expert.

  Trying to avoid SPOFs for Resque and Redis. Ultimately the client is going to be PHP via (https://github.com/chrisboulton/php-resque). After going through and finding some workable HA for nginx+php-fpm and MySQL (mysql master-master setup as a way to simply master-slave promotion), next up is Resque+Redis. Standard install of Resque uses localhost Redis (at DigitalOcean). I am heavily depending on Amazon Route 53 DNS failover to try to solve this. resque1.domain.com points to localhost redis (redis1.domain.com) = same server resque2.domain.com points to localhost redis (redis2.domain.com) = same server Do resque.domain.com with FAILOVER resque1 as primary and resque2 as secondary. What this means is that most of the time (99%), resque1 should be getting hit with resque2 as just a hot backup. This lets me just have to get 2 servers and makes sure that any hits to resque.domain.com goes somewhere The other way to do this is to break out resque and redis into 4 servers and do it as follows resque1.domain.com - redis.domain.com resque2.domain.com - redis.domain.com redis1.domain.com redis2.domain.com Then setup DNS Failover resque.domain.com - primary: resque1 and secondary: resque2 redis.domain.com - primary: redis1 and secondary: redis2 I'd like to get away for 2 servers if I can but is this 2nd setup much better or negligible? Thanks, Chris

• 64 bit vs 32 bit

  - by user53864

  When I was doing my course MCSA, I'm taught the following: With a 32-bit processor only 32-bit operating system can be installed. with a 64-bit processor both 32-bit & 64-bit operating system can be installed It's said 64-bit os cannot be installed on a 32-bit processor. I just want to make sure the above points because recently I'm asked to installed Windows Server 2008 R2 Enterprize and while installation it showed only x64 and it simply installed it. I was thinking all the computers in my office having a 32-bit processor. If so how it could be possible to install a x64 bit os on a 32-bit processor? or I'm wrong with the 1st point or the processor may be of 64-bit(I don't know how to check). I'm confused... One thing what I know the benefits of 64-bit over 32-bit is faster operation. If anyone could tell me other benefits, it could be helpful for me. Thanks!

• Tomato OS: "memory exhausted" running vi .... how to solve?

  - by Sam Jones

  I have set up tomato (shibby) on an asus RT-N66U router. It works great. I loaded up a few pieces, like transmission and optware. I can run vi, but when I run vi it fails with a "memory exhausted" error, and the terminal session hangs. For reference: If I simply start "vi" it runs fine. But if I specify vi I get the memory exhausted error, even if the file I am opening is just a couple of hundred bytes in size (like fstab). I discovered that my swap partition was not properly set up, so I did that. The swapon command now indicates I really do have a swap: [root@MyRouter samba]$ swapon -s Filename Type Size Used Priority /dev/sda1 partition 32900860 0 1 How can I get vi to work? Thanks!

• My hard drive seems to be overheating... what should I do?

  - by George Edison

  After a cold boot, the hard drive in my notebook jumps to 56? within an hour or so of idling. Is 56? a cause for alarm? Notes: The notebook is on a flat desk and none of the vents are obstructed. The video card is currently at 55? and the CPU at 50?. It's a Western Digital 250GB hard drive. SMART reports the drive healthy but does warn that: Edit: this problem had a very surprise ending. I inverted the notebook and unscrewed some of the panels on the back (there was one covering the hard drive, and one that provided access to the memory). I couldn't see any dust, so I simply screwed everything back together and powered it on... and it worked! The temperature is now staying at 46?, and it feels notable cooler to the touch. So I can only assume that some internal fan was malfunctioning or something. Whatever the case, it's working now so I won't complain. Edit: I have an SSD now, so temperature isn't as big an issue as it was when I had a mechanical drive.

• Problem running mysql client, cannot connect to mysql server

  - by ehsanul

  Edit3: Thanks for the help everyone. Sorry for wasting anybody's time, but it seems like a simple reboot solved it. I should've known better, but I just had the assumption that the "restart" solution is mostly valid just for MS Windows (no offense). I'll keep this in mind before I ask a question here again. I installed the mysql-client-5.0 and mysql-server-5.0 packages on Ubuntu 8.04, using sudo apt-get install. When I try to run the "mysql" command, I get the following error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) To verify that mysql server is running, I tried this, and it does seem to be running, with the correct socket too: $ ps aux | grep mysql root 13388 0.0 0.0 1772 528 ? S 06:24 0:00 /bin/sh /usr/bin/mysqld_safe mysql 13553 0.0 1.4 127012 15332 ? Sl 06:25 0:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --port=3306 --socket=/var/run/mysqld/mysqld.sock root 13555 0.0 0.0 3008 696 ?

Note that I'm completely new to mysql. Edit: As requested in comments, the exact command that is returning the error is simply "sudo mysql". And when I check netstats for active networks services, I do see an entry for port 3306, with Protocol: tcp, IP Source: 127.0.0.1, State: LISTEN Edit2: It appears as if the /var/run/mysqld/mysqld.sock socket doesn't exist (if I'm interpreting the following output correctly): $ ls -al /var/run/mysqld/ total 0 drwxr-xr-x 2 mysql root 40 2009-08-06 06:36 . drwxr-xr-x 20 root root 860 2009-08-06 06:25 ..

• Drobo FS vs. MacBook Pro: Finder works, Drobo Dashboard doesn't

  - by dash-tom-bang

  Does anyone have any experience with the new Drobo FS, specifically using it from a MacBook Pro? My experience thus far is this: Set up the Drobo Dashboard software (hereinafter called simply 'Dashboard') on my WinXP machine, which is hard-wired to the network to do the data migration from my NAS-that's-being-replaced (a 250G SimpleShare which works well enough but I was always afraid of losing the one disk). The Dashboard seems to work ok, except that the DroboCopy function doesn't work at all. This is the backup solution, which I can configure, and if I launch it (e.g. to back up from the old NAS to the Drobo) it spins the NAS, seeking the drive all over hell and creation, until finally giving up an hour+ later with zero files copied. Selecting only a subset of the data yields the same effect albeit more quickly. On my Mac I installed the Dashboard software too, since most of my fiddling with the device will be from my couch in the living room. Finder connects to the box just fine, fwiw, but Dashboard just sits there, "waiting for connection." This is considerably more bothersome than the above paragraph, but I figured I'd give whatever information I have. Drobo is insisting that I send them this "Debug Log" file that their software generates. Does anyone know what's in it? It's encrypted and they won't tell me, which spooks me just a bit; not like I'm terribly concerned about privacy but I don't want to be sending personal information out to every clown who says they "need" it in order to help me. thanks a ton, -tom!
