Server :: Logins Via SSH To Server Are Extremely Slow

Jun 13, 2010

Running RHEL 5.5 x64 with the latest updates. Running Oracle 11gR2. Server has 8gb ram 2xcpu 2.4 xeon.Only running one fresh instance of Oracle, no applications are even pointed at the DB.Two Issues...

1. Logins via SSH to server are extremely slow, about 30 seconds after typing password
2. Once I am logged in, launching sqlplus is very slow. After typing password, sqlplus hangs for 15 or so seconds.

Even when I am actually at the console, login of course is instantaneous.. but sqlplus still has the same issue. CPU is at 0% no swap is being used. Shouldn't be a network issue, on the same network.

Server :: VsFTPd - ReverseDNS IdentLookups - Slow Logins

Dec 17, 2010

Question on vsFTPd. I just switched to it from ProFTPd. With ProFTPd clients on the LAN that connected to the ProFTPd server on the LAN had slow logins with their FTP client until in the ProPFTd config file I uncommented these two lines:

#UseReverseDNS off
#IdentLookups off

Now that I"m using vsFPTd, I was wondering if there were similar settings since I see logging into the vsFTPd server is slow (20 second delay).

Server :: Debian Quadcore With 150 Mount.cifs Going Extremely Slow On Commands

Jul 9, 2010

I've mounted a kind of proxy to map some cifs folders, 150 aprox. It umounts and mounts everything each hour, to check on changes on a configfile managed by a secretary, she just edits a file with names and I prepared a cron to notice the new mountpoints. It's a debian, no desktop , no nothing else. Just mount.cifs and apache2 to let the master webpage access to some files on each user samba home. The server has 4 cores and 2Gb of RAM. It's brand new, but it goes very slow.

[Code]....

Does anyone have an idea why is that working so slow? The apache is working well, it's the shell which is working extremelly slow.

CentOS 5 Server :: RAID0 - Getting Extremely Slow Read / Write Speed

Jun 28, 2010

I am new to Centos and linux in general. I have just got myself a Dell 1950 server with 2x 1T SATA2 hard disks in it. now the server comes with a PERC5i Raid card with 512Mb. Well I put these in raid 0 and the raid card initilzed the disks to 128 writeback and read ahead. When I loaded centos it did not recognize the dell layout so therefore wanted to initalize it again, so I done this as it wanted. Now I created a 80gb boot and o/s partition and a 100gb swap the rest was created into LVM space to run solus vmwear. But I found the raid 0 to be getting extreamly slow read and write speeds.

Example same disks
Desktop PC max 214mb/s windows vista 64
Server with centos 104mb/s

Now I am not sure but I am told that I need to align the o/s with the raid card settings but I have no idea how to do this. How to do this in plain easy step by step instructions. I mean how to calculate it, how to format the disk this way, and what files to edit where if needed. I have spent hours trying to figure out why my raid 0 is slower than a single disk.

Server :: Server Slow : Apache Mysql Fine Tuning Server For Faster And More Responsive?

Apr 21, 2011

I'm running a linux cloud server with the following config
1.2ghz Processor allocation
752MB Ram

The site loads slow and clicking a link almost freezes the page for a second. Also, the page loads could be much faster. We've been running mysqltuner and have pretty much optimized all slow queries. Is there anything we can do to fine tune the server for faster and more responsive?

Httpd.conf

Server :: Securing Ssh Logins ?

Sep 15, 2010

We have a public server and it can be accessed from any where through ssh.

My question is my server should not allow anyone directly to login as root user. First he should login as normal user then he should switch to root user.

I also have another questions is there any specific linux command is there to end other users ssh session without rebooting the server.

Server :: Samba Not Accepting User Logins?

Feb 23, 2011

I have a samba server that I had setup using the default smbpasswd backend, and it worked fine. So long as I remembered to use smbpasswd/passwd to setup a user with a username and password matching the account name of a Windows 7 user, then that windows 7 user would be able to navigate the shares with their permissions correctly.I have switched over to using ldap, and: the console/ssh of the machine can correctly use any of the ldap logins getent passwd/group both show the complete listing my Windows 7 machines can all ping the samba server by its netbios name my Windows 7 machines all prompt for authentication if I type \MACHINENAME into explorerHowever, all attempts to access the shares now continually ask for you to enter your username/password, and then fails anyway.No errors appear to be generated on the server (unless I'm missing a log somewhere). Having hunted around on the web, I'm wondering if it has to do with generation of machine accounts (since it tries to access from MACHINENAMEUSER). Without ldap setup, I didn't need to worry about the machine name, but I'm thinking that maybe smbpasswd took care of this somehow.I use the smbldap-useradd tool to setup a user account, which appears to correctly setup the user in ldap, such as:

Code:
dn: uid=sharer,ou=Users,dc=intbus,dc=net
objectClass: top

General :: Top Causes Of Slow Ssh Logins

Jul 22, 2010

there are 2 spots where I see a range from instantaneous to multi-second delays.Between issuing the ssh command and getting a login prompt and between entering the passphrase and having the shell load.Now, specifically I'm looking at ssh details only here. Obviously network latency, speed of the hardware and OSes involved, complex login scripts, etc can cause delays. For context I ssh to a vast multitude of linux distributions and some Solaris hosts using mostly Ubuntu, CentOS, and MacOS X as my client systems. Almost all of the time, the ssh server configuration is unchanged from the OS's default settings.

What ssh server configurations should I be interested in? Are there OS/kernel parameters that can be tuned? Login shell tricks? Etc?

Server :: Primary Domain Controller Would Be A Better Way To Manage Logins?

Feb 17, 2011

We have a LAN with mixed Windows workstations win 2000, winxp, vista, win 7, linux servers all in a workgroup. Most applications used on the LAN are windows based, with a growing number of python apps. A friend suggested a Primary Domain Controller would be a better way to manage logins, resources etc. I don't wont to use a Windows based PDC, what would you suggest as a linux based PDC? I have heard about TURNKEY PDC, but it uses Samba 3 and apparently doesn't handle Active Directory in Windows.

Fedora :: Extremely Slow Machine

Jan 27, 2010

I run F12. Since some days my laptop has become very sluggish. In Mozilla, switching between the tabs takes like seconds instead of fraction of a second. Also minimizing and mximizing windows takes long. Switching between the windows too takes long. Now I can't see the cursor while typing this post. I disabled some services that start at the boot time. I'm posting a list of services that are on in the runlevel 5 as that's the one I use.

Ubuntu :: 10.04 Extremely Slow While Booting Up?

May 1, 2010

Not much else to say. I'd say it takes at least a minute before I get to the login screen. After that it runs fine and most of the previous problems I've had since upgrading have resolved themselves. why it's taking so long to boot up?

Ubuntu :: 10.04 - Live CD Extremely Slow?

Jun 12, 2010

Have a little problem/annoyance. I was trying to use a Live CD with Lucid Lynx 10.04 x86 edition and the speed was incredibly slow. I took more than 10 minutes just to start. I noticed the CD drive stopped spinning (or spinning so slow I couldn't hear it) at times, then starting up again. I also noticed multiple i/o error in the logs after it finally booted up. The reason why I think this is a bug and not my drive/cd is simple:

a) The MD5ed the iso and even made two CDs with different burners. I tried older Ubuntu as well as several other Linux distros and the Live CD boot time is much faster (1-2 min). Tried the CD on a way, way older ancient laptop and i booted just fine and much faster.(I will provide any other info if needed).

Ubuntu :: Compiles Are Extremely Slow

Aug 12, 2010

At work, we use Ubuntu to compile large numbers of C, C++, Java, and AIDL files.My system is a Core i7 Quad-Core with 8GiB of RAM. Prior to this install, it ran Ubuntu 9.10, 32-bit. A basic compile took roughly 45 minutes.I just did a clean install with (x)Ubuntu 10.04 64-bit. After setting up the build environment to allow 32-bit libraries (mobile development), a compile took roughly an hour:15.

Ubuntu :: Extremely Slow Start Up?

Oct 10, 2010

I have had an extremely slow startup (upwards of a few minutes) for awhile now, and nothing seems to work to fix it. Regular boot time is far slower than it should be, and the time of logging in to a workable desktop is just really bad. I will log in, and then I will either get a blank desktop screen for awhile or an all black screen until the desktop will fully load with errors from gnome-panel and AWN not starting up automatically.Some of the fixes I have tried:

Disabling floppy from bios

Downgrading gnome keyring

Removing gnome* and gconf* from the home directory

Putting this script in /etc/init.d
#!/bin/sh
echo "nameserver 0.0.0.0" > /etc/resolv.conf

Here's my bootchart and a link in case the upload has problems http:[url].....

Slackware :: PSX Emulator Extremely Slow On 12.2

Aug 3, 2010

I downloaded the emulator called pSX so i can play my playstation cds in my computer. on my laptop i have slackware 12.2 installed.

The dependencies for the emulator are:
opengl
gtk
alsa
gtkglext
libxml

I found the appropriate packages for all of these (with the exception of opengl, I assume that means it's preinstalled, correct me if I'm wrong) and installed them. the emulator runs, at about a quarter the speed it's supposed to. I get no error messages in the terminal, just the huge speed drop. has anybody else gotten this emulator to work fine in slackware?

Ubuntu :: Extremely Slow Bootup In Karmic?

Feb 26, 2010

I know this has technically been posted but I think my situation is a bit different. People have been complaining that karmic is slower to boot. But from what I gather, it's only a few seconds extra due to an extra splash screen. I'm running Ubuntu Studio and mine takes like 5 minutes and is showing me 3 splash screens! 2 for regular Ubuntu and 1 for studio, which is the most sluggish of the three.

My computer is a Toshiba Satellite A75
2.8 ghz pentium M
1.5 gb ram
Radeon graphics
60gb hdd

EDIT: Also, recovering from hibernate takes a few min. Related?

Ubuntu :: Extremely Slow Swap Performance

Jun 24, 2010

I'm getting horrible (unusable) performance every time swap is accessed. This was compounded by the GEMS leak and a few other memory leaks, but now under normal non-leaky memory usage swapping is still intolerable. For instance swapping out ~300mb when I opened a new program with RAM full resulted in the system nearly freezing up for about 3-5 minutes (however long it took to brew a cup of coffee and come back to the system just finally unfreezing).

Ubuntu Servers :: MySQL Extremely Slow

Jan 27, 2011

I've got Ubuntu Server 10.04 on a fairly beefy box (quad-core xeon 2.67ghz, 2gb ram) Standard mysql-server installed, with many databases.Lately, mysql has been extremely slow and almost non-responsive. Server loads are low.Running mtop reveals many, many processes from the user: debian-sys-maint querying the information_schema table with the exact same query, over and over."Select count(*) from tables where engine = 'innodb'"

This is adversely affecting my database server, and thus my websites which rely on mysql. Every search I've done looking for more information about the debian-sys-maint user shows problems where that users was deleted. The user isn't deleted.

Ubuntu :: Extremely Slow Terminals In Virtualbox?

Mar 18, 2010

I'm running windows 7 on my laptop at work (I know, I know, but I have good reasons). In order to at least some of the benefit of Linux, I run Ubuntu in virtualbox. Things pretty much work great, except more often than not, gnome terminal is really sluggish. It seems like a simple program - I can get videos to play fine, why can't I type text. I installed xterm, and it has the same problem.
