host: localhost
port: 5432
user: postgres
maintenance db: postgres
And I receive the following error:
An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.
I have a problem between a jail root (so a group of users can access through sftp to Apache directory (var/www) an not get out of this directory.
1. I have the group 'sftponly', I need to access / var / www for sftp (read only)
2. On the other hand I need that user www-data (Apache) is the owner or at least have write permissions in the same directory (/ var / www)
The problem comes when the two needs together, as from what I read, to do jailroot in a directory is necessary for the owner is root and any other user has write permissions on it.
If along the jailroot with write permissions then attempt to connect to the client via sftp throws me the following error: "Error: Server unexpectedly closed network connection"
Permissions system User/group/Others doensn't work to me, so I tried it with ACL, but I have the same problem when I grant write permissions to the apache user.
Does anyone know how can I do for the user www-data can have write permission in the Apache directory and be able to create a user or group of users who are "locked"in this directory to enter sftp?
I am facing a problem with Eclipse after I installed it today. It keeps closing [unexpectedly] after I click a choice like closing one of the pop-up windows that shows after I choose an option from the menus in the top. With no errors returned or shows up! As an example, when I choose to create new project, and fill in the project information [Name, type, path] and when I click FINISH all Eclipse closes, and I need to re-open it again [I find the project that I created there].

View 1 Replies View RelatedI am running an Ubuntu Server on a VirtualBox VM running on my windows machine. So I've created a self-signed certificate using the following tutorial: [URL]
From this tutorial I'm left with 3 files:
server.key
server.csr
server.crt
Then I found this very similar tutorial that has an extra bit on installing the certificates in apache: [URL] So I followed it's instructions which boil down to this:
[Code]...
So I'm thinking this should work now. However in Chrome I get: 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. IE8 gives me a typical "Internet Explorer cannot display the webpage" Note that [URL] fails while [URL] works fine, so it's definitely something in my ssl setup I'm thinking.
I'm trying to connect with my server via telnet, but when i sent the command (telnet xxx.xxx.xxx.xxx Port) doesn't works and shows then follow error: Unable to connect to remote host: Connection refused, It happens with any port. Is strange but my telnet services works (telnet xxx.xxx.xxx.xxx), In addition, i tried with firewall enabled and disabled and the problem still happens. My centOS run on virtualbox.

I have configured rssh 2.3 with openssh 5.8 on RHEL 5.6 64 bit to restrict the users to scp and sftp. When i try to sftp or scp it gives error connection closed.

As the title implies, I'm having an issue with svn, whenever I try to make an svn action, I get: svn: Network connection closed unexpectedly
I've done some Google-fu on this, and the obvious culprits don't seem to be at work. Specifically, the svn server does not use a nonstandard port, and I'm not using Tortoise SVN or putty, just going directly from the command line. Additionally, I was able to use the server as recently as this morning and no coworkers are having problems.
My server works fine, is never overloaded, but suddenly the Apache workers start to rise up to the limit (450), and are all internal processes "OPTIONS * HTTP/1.0" with "C" (Closing connection). Then the server runs very slow and this can take several hours until I restart Apache.e.g. today:
Code:
0-0 24789 1/7/7 C 0.10 3980 0 0.0 0.01 0.01 ::1 my.server.com OPTIONS * HTTP/1.0
1-0 24790 1/2/2 C 0.03 3989 0 0.0 0.02 0.02 ::1 my.server.com OPTIONS * HTTP/1.0

System was fine with :Ubuntu 9.04 (had also installed kde )then....I wanted to try some change to gdm so i downloaded gdm while building it , it asked "PAM" libraries to be installed so i installed PAM ... but ignored the instruction to reinstall SHADOW (library i guess..),Now :on booting system i get login menu but i am not able to login , it says some critical error occured
1) install new copy of UBUNTU and remove old
ps :1) i can log into system through live cd
2) i can use recovery mode boot and log into terminal as root(startx is not working from this terminal..
I am not able to login to server from console attached to server, every time i enter username & password but it again asks for username & password. But when i try to login to server from remote machine, login happens properly.
View 4 Replies View RelatedI'm running 5.2, mostly updated. I've got a user account that is really only used by some clients (Polycom phones) to log into vsftpd. Once every few days or so, the password on the account changes to something other than what I've specified, and I can't figure out why. The other user accounts on the system don't seem to be affected, though none of the other accounts are used by/for vsftpd.
chage shows that the account password should never expire, so I don't think that's what's happening. I'm wondering if VSFTPD is just not playing nicely with PAM. Is there a way to explicitly prevent vsftp from changing a user password? I can't seem to find anything like this.I'm not sure if this makes any difference, but the system is clustered using heartbeat/drbd. The users are unique to each of the nodes in the cluster, though, so I don't think this should really have any effect.

Does anyone know what could be causing a Remote Desktop connection to a 10.04 box to be closing after some period of time? I have three systems all running 10.04 with Remote Desktop enabled. I'm using UltraVNC on Windows 7 to connect to them. If I open a connection and leave it open for a long time (like overnight, for example), when I come back in the morning, I still see the VNC window but as soon as I click on it, it closes. I can immediately open a new connection to the box but it now shows two active connections. At first I was thinking maybe there's an idle timeout value but given that Ubuntu still seems to think that the original connection is active, maybe the problem isn't on the Ubuntu side but on the UltraVNC side?
View 1 Replies View RelatedI have a script which takes a file as input and reads it in while loop cuts the name of table and stores in a variable opens DB connection and queries for rowcount in that table closes the connection reads another file and then follows step 1 through 4 till EOF is reached. Now this script is taking longer to execute maybe because the DB connection is opened and closed each time.
My scripts is:

cat logcountOP | while read LINE

I was thinking of changing this.I want to open the DB connection just once and then query it for all tables and then exit.

One of my colleagues was working on my system (Centos 5.6). He deleted some files from the /tmp directory (he thought he was cleaning up files). Right after that, he rebooted the system. I now can no longer login.
Prior to this, here's what I see following a reboot code...
no matter what I use, I cannot login -- it takes me back to the (none) login: prompt
Any ideas? I know that deleting from the /tmp directory could lead to catastrophic results, but he thinks he only deleted a specific set of files.
Is there any way to setup the Centos Directory Server without an internet connection?? i tried using the command: yum install centos-ds

Everything was fine yesterday, but today, the situation is the following:
When I try to login as root, using Gnome, after I enter username and password, it can do three things:
1- It brings me back to the GUI login screen again
2- Brings me to the prompt login screen (black)
3- It lets me in but I have no top or bottom navigation bars. (Sorry, cannot remember the actual names...) Sometimes I have access to a console screen, which allows me to reboot, and sometimes not, in which case I have to do a cold reboot. Not good.
The last attempt I made, I used the KDE interface and everything was fine.
I really don't understand what happened between yesterday and today, nobody but me uses this system at home and remote logins for root are disabled.
The systems is CentOS 5.3 with SELinux enforced.
