Unable To Connect Via SSH With Centos5 X64
May 27, 2007
I have been struggling with a couple of new servers that we want to run Centos 5 on. For a second assume that is our desire so going back to 4.x isn't an option yet.
Now while I mention Centos 5, the problem seems to be with PAM and x64.
When trying to login to the server via ssh, the login succeds but then immediately kicks the user out. I have tried this with root and another user created. I have set the UsePam option to no to try to resolve this in sshd_config.
On the H-Sphere forum I found this reference:
[url]
" if i try to connect with ssh and i enter the right password i get an error and ssh closes the connection. The answer already was in the ticket you opened:
Quote:
That is known bug dealt with PAM authentication.
The bug was fixed for i386 systems long time ago. But it was not fixed for x86_64 architecture.
We build FreeVPS kernel new version 1.5-13.1 for x86_64 architecture to fix the problem.
We also installed the kernel into the box IP 64.71.227.16.
Please reboot the box with the new FreeVPS kernel version: 2.6.9-freevps-1.5-13.1smp.
Let us know the result."
Does anyone know how to resolve this? A reinstall of PAM was attempted by a well known sysadmin here but to no avail.

I've been getting a lot of complaints today on my forum that users cannot view their websites which are subdomains on a seperate domain that I own. It makes no sense why they would have access to the forums which is on the same dedicated server, using the same IP, and with the same nameservers as the site they cannot access. This issue started last night out of nowhere.
Where should I even start looking? It appears to only be with overseas users since none of the US and Canadian users have any issues with either domains or their subdomains.

Yesterday I had to install a renewed SSL Certificate. Managed to get it installed, in Plesk under domains/www_mydomain_com, but I also deleted the default SSL from the server/certificates area... So then I was getting an dns 500 error when browsingour site and I could not start httpd from within plesk. Went in through SSH and tried to start it from there and got and error stating it could not find the SSLCA cert it was looking for. So I edited my httpd.include file to point to my new certificate. Now http works, but my email has stopped? What gives how could the two be related!
I can log into my webmail, compose message and when I send I get:
Warning: fsockopen(): php_hostconnect: connect failed in /usr/share/psa-horde/pear/Net/Socket.php on line 108
Warning: fsockopen(): unable to connect to 127.0.0.1:25 in /usr/share/psa-horde/pear/Net/Socket.php on line 108
I have started and stopped psa, qmail. Rebooted the server. I tried the telnet localhost 25 but I get connection refused. Anytime I check qmail status it says stopped. Don't know if that is right or not. I know I am not recieving emails asI have sent many today through other accounts and they all come back undeliverable.
We do run an online store as well so I am kinda nervous when our email goes down! Time to hire a server admin?

I just switched to a new server last month and Im having a problem where a lot of my members and even some of my mods are unable to connect to my website. They are just getting a page cannot be displayed error. The website is ftascene(dot)com. Is everyone here able to connect to the site, and any idea why not everyone would be able to connect?

I have not been able to connect to my server via browser, ftp or email since my server had a OS reload & security package installed.
If I disconnect and remove my wireless router I can access the server directly from the modem. When the Linksys WRT54G is connected I can go anywhere on the net with no problems, except my server.
Is there something they might have done at the server to block wireless router access?
I get a timed out message when I ping any of the IP's on the server with the wireless router connected.
Linksys has been of no help and I have talked with Clearwire who owns my modem.

When i go to my website or any page under the domain it's just white. Blank nothing, nada.
"Failed to receive status information from Apache. Unable to connect to local httpd server."
This error message appears when i click on "apache status".
Is this because of the network issue? Or is it because of something I did myself?
I did a google search and came up on some solution, I did them and nothing.

After changing my web hosting (same system : VPS, same version of linux : CentOS 6 , but passage from Plesk 11 to 12), i am now unable to connect remotely via TCP-IP to my mysql databases (with third-party tools like Mysql Workbench, Toad...) ! I never met this problem before.
The only way to connect is to use a "Standard TCP-IP over SSH" connection method ... but i don't want (i did'nt need this method before) !
Though, remote connections are allowed from any host in the settings.

I had Plesk 10 installed on my openSUSE system (was a low version, maybe 11 or less) and then decided to upgrade to 11.5. So I did distribution upgrades to openSUSE 12.3 and everything went smoothly, except for some services like mysql and php. So I used Plesk autoinstaller to fix the php error and edited an outdated line in mysql configuration and both services ran smoothly!
Then I downloaded Plesk autoinstaller and ran the autoinstaller, but was surprised by this error message:
===> Checking for previous installation ... found.
ERR (3) [panel]: Error during product key mode determination, details: Unable to connect to database: ; trace: #0 /usr/local/psa/admin/plib/functions.php(2821): isPpaKeyRequired()
#1 /usr/local/psa/admin/plib/common_func.php3(11): require_once('/usr/local/psa/...')
#2 /usr/local/psa/admin/plib/api-common/cu.php(5): require_once('/usr/local/psa/...')
#3 /usr/local/psa/admin/sbin/httpdmng(8): include_once('/usr/local/psa/...')
#4 (main)
Unable to connect to database:
- My MySQL version is: 5.5.33 openSUSE package
- I did run mysql_upgrade with my admin username and password (password from: /etc/psa/.psa.shadow) and it worked successfully and fixed all of the errors, I did so after running the auto installer first, but then ran the installer again and the problem was still there
- I can access my web page, but it still doesn't connect to MySQL either.
I believe this is a problem with MySQL, but how can I make sure or detect what exactly the problem is

Trying to get something sorted on a VPS that I want, but when I try to run a script I get the following error:
cp: cannot stat `/lib/libxcrypt.so.1': No such file or directory
which is easy enough for me to understand however, I cannot find what package I need to install to provide the file.
I have searched for libxcrypt* on the box to see if its hidden elsewhere but to no avail.

We have a weird issue on one of our centos 5 servers, running the 2.6.18-53.1.4.el5 kernel
for some reason we cant mkdir any directories that are numerically named
ie mkdir 5789 doesnt work
alpha and alpha numeric work fine... ie mkdir ab567a
Quote:
[root@]# mkdir 6
mkdir: cannot create directory `6': No such file or directory
[root@]# mkdir 6ab
[root@]#
Someone suggested the adore-ng rootkit was to blame but we have run ossec root check, rkhunter and chkrootkit and even run clamav over the drives and cant find anything nasty
