Software :: Getting A Portable Emacs To Use For Troubleshooting GNU?

May 6, 2011

I need a portable emacs to use for troubleshooting GNU/linux machines. A USB stick is the preferred medium as some of the computers I will work with may not have an optical drive.

Will I need separate versions for 32- and 64-bit systems?

Server :: Centos 5.5 Box Troubleshooting ?

May 13, 2011

The server is booting up properly and the system is running. When browsing web sites on the sever and they seem to run fine. But when you make requests to it, it seems to take a long time to process stuff. Such as large mysql request. Even to the point it freezes. It seems that if you make a request of some sort it just over loads. I have checked the logs and the most I can get from it that one of my wiki sites that seem to be getting nailed with spam bots trying to getting which is one of the databaes that where repaired could be slowing it down A LOT. Now I did find a couple databases that where marked as crashed and they have been repaired. I am not really sure what is causes the errors since the HD space is fine, ram is fine, internet connection is fine...So I am not familiar with diagnoses linux as much as I am with a windows pc. I am not real shell friendly. I am not good with the basic troubleshooting commands to try and identify the source of the problem to correct it. Could anyone point me the way...

Thanks in advance and I apologize for being a ra-tard on these. I should know this stuff more than I do running a server like this. It was created in 2006 and has been problem free since. Another thing, mass emailing isnt working either. It may be mysqld related. Sorry for the fragments and such. It also seems the SMTP isn't working properly as well suddenly.

Another error I been seeing:

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16 bytesPHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16 bytes some times I see this as a 32 or 64 bytes as well.

FTP Connection: It is also slow when making ftp connects. It is extremly slow but they finally do complete. It can be just a simple connection to display content. Slow.

Debian :: Troubleshooting New Wireless Network?

Aug 16, 2010

I have had no problems connecting to any of my wireless networks in the past. Right now I am at a friend's house and can't get internet access with my laptop. I have entered the appropriate fields in /etc/network/interfaces (as I usually do)

auto wlan0
iface wlan0 inet static
address 192.168.2.64
netmask 255.255.255.0
broadcast 192.168.2.255
gateway 192.168.2.1

I checked this info with the router's web interface and everything seems fit. The network does not have a password. I have tried adding "wpa-ssid belkin5g" and "wireless-ssid belkin54g", and neither one works (can't ping the router after bringing wlan0 down then back up). I have also tried connecting with DHCP instead of setting a static address.

I have a really weird problem, when I play any ..... video, gnome crashes. I've tried other similar services, and everything works just fine. As soon any ..... video starts, gui crashes, audio actually keeps on going and I get some weird picture on screen that keeps on blinking. I've tried searching around for a similar problem, but couldn't find anything.
I tried looking in /var/log/messages, and tried looking into dmesh, kerneloops...but no luck.

Any idea how to start troubleshooting this?

General :: Troubleshooting - Cannot Login To Server Via SSH/Console

Apr 5, 2011

I got two computers with the exact same symptoms today: Both seem to be alive. They answer pings and they host virtual machines which are working. However, I cannot login via SSH. I get

$ ssh -v obelix
OpenSSH_5.3p1 Debian-3ubuntu6, OpenSSL 0.9.8k 25 Mar 2009
debug1: Reading configuration data /home/mike/.ssh/config
debug1: Applying options for obelix

On the console I can switch the ttys and enter my login credentials. After that I see the GNU/Debian Linux welcome message an no prompt. The system seems to hang. I'm able to switch the tty again and login with the same result. (I tried that three times now and I start running out of ttys.) A search on the Internet suggested some ressoucre shortage. How could I release some resoucres than? How could I further investigate the situation before just trying a hard power off?

Ubuntu Servers :: Apache SSL Configuration Troubleshooting?

Jul 19, 2010

I am trying to configure Apache on my server to work with ssl, but everytime I visit my site, I get the following message in my browser: SSL connection error. Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.

Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. Just some background on the situation: I am using Ubuntu 10.04 desktop edition. I installed apache by installing zend server (it installed apache automatically). I then installed openssl. Non-https pages work fine on the site. I tried getting trial certificates from multiple certificate sites but nothing is working (same error). I was previously hosting my site on another server on which ssl worked just fine. I also tried using the key and crt file from that server, but I got the same error. The domain name and IP are still the same though. My SSLCertificateFile and SSLCertificateKeyFile are pointing to the correct directory and files.

Ubuntu Networking :: Server 10.04 Network Troubleshooting?

Sep 1, 2011

I've got a server that I've been trying to get Ubuntu Server 10.04.01 LTS installed and running on and I've gotten incredibly close to having it work, but the Network is still giving me issues. The installer went off without a hitch (once I fixed some optical drive issues) and it has actually detected the "Intel Corporation 82576 Gigabit Network Connection (rev 01)" Dual-port onboard NIC which shows up when I run lspci. I statically assigned an IP, Subnet, DNS Server and Gateway to eth0 and things looked good. ifconfig showed that it was "UP", and I could ping localhost, but if I tried to ping anything on the LAN it said "Destination Host Unreachable".

Here's the ifconfig and lspci (snippet)

======== ifconfig ========
eth0 Link encap:Ethernet HWaddr 00:25:90:2d:26:98

General :: Desktop Environment - Where To Start Troubleshooting?

Oct 31, 2010

My problem started only after I upgraded my hardware. I'll describe the problem and the changes that led to it.

Problem: I have to restart my computer a second time before my icon set and controls are shown properly. The first time I boot up, I get an ancient looking set of controls. (By controls, I mean buttons, window splitters, etc.). My custom icon set is replaced by an ancient looking icon set I've never seen in Ubuntu before. (Maybe it is a Debian default? It certainly isn't stock Ubuntu). The Gnome panels are completely different from normal too. I simply reboot again and everything comes up the way it should. Every time I start my computer, I have to restart a second time. After that, no problems until I need to shut it down and start again.

I'm running a relatively new installation of Ubuntu 10.10. I changed the theme to a bisigi theme [url] and everything was fine. No problems at all until...

Changes: Then I upgraded my video card from an older nVidia to a GT430. I had to change a couple things in xorg.conf. For that, I just used the suggestions made by the nVidia settings utility. I also upgraded my mobo and RAM (from 4GB to 16).

These problems started only after I upgraded my hardware. Of course, the hardware upgrade involved the above noted software configuration changes. (xorg.conf was the only required change.)

I'm looking for ideas on how to troubleshoot this? I don't even know the first step. For example, what logs should I check? Should I suspect a hardware problem (e.g., bad video card) or is this software/configuration related?

I have an oracle database that is getting file i/o errors. I don't think it is the fault of oracle, but the nfs mounted filesystems. So ... to troubleshoot my next step is to see if Linux is having trouble with i/o. These are nfs mounted and there are many files located on the filesystem which is having the error. The error only occurs on one file.Does anyone know how to turn on logging for any errors received? I assume I need need logging for nfs daemon, but not sure. Please correct me if I'm wrong.

Slackware :: Systematic Method For Troubleshooting Low Sound

Aug 4, 2010

I have a system Intel sound chips running Slackware 13.1, full install. The sound is very low, whether through speakers or headphones. I have tried many things from searches online and especially here at LQ, including kernel module params, /etc/asound.{conf|rc|xxx} configuration, reading everything under /usr/doc/alsa..., etc... no joy. But at the end of the day I still remain unclear on any systematic method of troubleshooting alsa/chipset problems. So I am asking here for a systematic guide to troubleshooting and configuring alsa problems, including low sound in particular, but alsa setup and configuration generally.

CentOS 5 :: Gathering Additional Troubleshooting Information

Mar 30, 2010

One of our devices running CentOS 5--an 8e6 Technologies Enterprise Reporter network appliance--has started displaying the following three messages repeatedly, though not continuously.Best as I can tell, hard drive four may be experiencing sector errors.(The messages do differ slightly at times. For example, 16384 may instead read 49152 or 12285, and the two strings of colon-separated hexadecimal digits may also vary in content.)Other than these messages, the device seems to be running fine. Its internal diagnostics indicate no problems.I will, of course, call 8e6 Techonologies tech support. But, prior to that, I'd like to do some troubleshooting on my own. What other troubleshooting techniques may I employ to gather more information?

Ubuntu :: Common Terminal Commands Used For Troubleshooting In The Forums?

Aug 8, 2010

I need to know what commands we have people run in the terminal in order to help them troubleshoot their issue. The reason being, is I was reading a thread where someone was stating about how they had to do all this and all that from a terminal and what not and that there should be a GUI Tool.

Well I'm going to make a GUI tool that allows them to obtain all the necessary information (and fixes are possible too) to help with their issue that they're currently having. For example: I know we run lsmod for sound issues, but what other commands do you have them run to check sound, video, network, etc. It will be made in wxPython so that it can be easily sent to others. If it becomes quite useful, then maybe we could get it in the repos.

Ubuntu Networking :: Mounting / Automounting / Setup Troubleshooting

Jun 18, 2011

I need help to figure out mounting. I have 3 computers running Natty. 1 a desktop 64bit dual boot with Win7 (64) Home Prem; a dell inspiron mini (32bit) dual boot with Win7 Home Prem, and an old 486 Intel based PC running ONLY Ubuntu. My Samba shares are on an external HD currently residing on the 64 bit. I installed Mount Manager...still trying to figure out how it works exactly. I'd like to auto-mount the shares "routinely accessed" (shared network drive, network personal for each machine) allowing as needed access. Then the other personal network drives I would like to mount only when needed. Leaving local home drives password/share protected ... using the network personal folders as a place to add files or such that need to go to a local drive.

{basically I have 3 computers which each have a local home folder, and a network home folder; then I have a network shared share where open shares will be stored (email, calendar, most documents, theetc) each computer has a primary ubuntu user (user id 1000). I have 3 windows ids on 2 computers. each of these ids has been paired with an ubuntu user in smbusers; after this weekend I will only have 1 windows share and 1 user hopefully! so the other two ubuntu users will have non-existent windows IDs}Right now I can (from a non-server machine) access the shared network drive, but cannot access any others. (Makes sense...that share is totally open). On the remote drive I have samba the the installed but no samba directory and it hasn't been configured (obviously).On the standalone (where the HD is attached) I can access any of them by mounting them where they are listed under Places, but through the network menu I can access the shared drive, and the personal drive with just one password entry (my login or sudo password). The others whenever I enter my login/sudo password I get an unable to mount error.

I currently have 3 Ubuntu users & 3 windows users. I've assigned each Ubuntu user an window user name hoping that would make the authorizations easier. I'm currently using a generic Samba password and a generic Ubuntu login password but they are different. So one password for each, each user has the same passwords. I do allow guests using the guest group (not nobody, but I could change that easily enough)If I weren't so stubborn I'd just ditch the passwords, make all shares open to everybody, but eventually I hope to be able to do remote access (via mobile) and would rather just do it all from the beginning than mess with it later.I've been hesitant to mess with programming in the mount/unmount process because I'm not sure I understand it that well (which is why I installed Mount Manager). Problem is I don't understand it well enough to figure out how to use Mount Manager. I did see where automount will not work if you have to authenticate the share before mounting. One of the reasons I only want to automount the 2 shares for each machine. That particular process sounded like what i want for those 2 connections on each. But first I need to figure out mounting period I guess.I may be really confused, or trying to do something that I with my limited knowledge and needs really don't want or need to do....wouldn't be surprising! I'm known to make things more complicated than needed. If a simpler approach seems more logical feel free to share!

Ubuntu Networking :: Wireless Network Connection Troubleshooting

Jul 9, 2011

Just installed ubuntu 11.04 on an old pc. At first, I was unable use my wireless usb adapter (netgear wpn111), but was successful after installing ndiswrapper-common and ndiswrapper-utils-1.9 manually. cool! then I updated all packages successfully via synaptic package manager and rebooted.now I have lost network connectivity. the os still sees the wireless usb adapter, but I have no connectivity. the indicator applet shows an exclamation point.

How can I troubleshoot this? are there logs? can I fallback to a previous good state?I am new to ubuntu, but experienced in unix. note: my pc only has 1/2 GB memory if that matters. but, hey, it worked once.

Hardware :: Choosing Graphics Card To Minimize Troubleshooting

Jun 27, 2010

Im now in the process of buying new hardware for my computer (mobo, disk, memory...the works). Im researching what graphics card I should buy for my i386-system that causes the least amount of fuzz to get up n running with the right screen resolution and so on? It will be a Debian desktop system running X. I will be doing web surf, playing movies, streaming video, and using OO. No gaming. The graphics card will be a PCI-E card. My requirements are:

- Capable of screen resolutions up to 1680x1050 (22" screen)

- Dual-head (i want to be able to expand my dekstop to two diffrent screens). Double HDMI or DVI is not required, VGA and DVI for example is fine.

Debian Configuration :: Custom Multiple - Boot Troubleshooting-System?

Aug 16, 2010

I want to build a custom system and I need your opinions. I have an old laptop which I want to configure as a system for troubleshooting purpose, my idea is to have multi-boot system with multiple root file systems, e.g. one root file system has only BIND to work as DNS server, another root file system has only Samba, etc., and I can choose which system to boot into from grub, or a custom menu after booting grub.

I thought of setting multiple partitions and install a full system on each one, but I thought that there might be a better way to do this, I'd like to hear your opinions.

Server :: Troubleshooting/resolving Random Kernel Panic On Multiple?

Jun 22, 2010

I'm having a strange problem on some of our Debian servers. It all started about three weeks ago when we moved our virtual environment (VMWare ESX3) from a SAN to a NAS (NetApp). At first I thought it had to do with that move but since the other 9 servers are working perfectly I eliminated that idea. For over a year all 12 Debian 5 servers have been working great without mentionable failures. All servers are (where) up to date with the latest patches. About three weeks ago I started having kernel panics with the following message on three of our servers:

Code:
Code: Bad EIP value
EIP [00000000] 0x0 SS:ESP 0068:f6d7da18

Kernel panic - not syncing: Fatal exception in interrupt and other times it looks like just a dump of hexadecimal data. The only difference between those 3 servers is that they have several mounted shares connecting to the NAS using CIFS. So I was thinking that it might have to do with an update of some kind in regards to smb. I recovered an image from a month ago, before the troubles began, copied over the data and MySQL databases and configured the 'old environment with recent data' exactly the same with MySQL master-master replication, document synchronization and load balancing. This task I performed last night (no other way since it's a production environment). Up to this time neither of the two 'restored' servers had a kernel panic. The one that has not been restored is having one at random about every hour and a half. Following are the different versions between the 'at this time' working server(s) and the failing one:

Code:
FAILINGWORKING
samba-common 2:3.2.5-4lenny122:3.2.5-4lenny9
smbclient2:3.2.5-4lenny122:3.2.5-4lenny9
