Feb 11, 2010
I have 2 computer: 1 computer install ubuntu v9.10, in this computer already installed openssh-server and openssh-client, and 1 computer install windows. In computer with windows , i used putty connect to computer with ubuntu, but i can't connect. I don't understand what's error. In the Putty , i configured: IP : IP address of computer Ubuntu. Port 22 Connection Type SSH This is error: "Network Error: Software caused connection abort"
In computer with windows, i can ping computer with ubuntu and in computer with ubuntu i can ping computer with windows.
I already checked computer with ubuntu : /etc/ssh/sshd_config: in this file port 22, PermitRootLogin yes.
And in this machine installed with openssh-server, and openssh-client. But in this time, this error is maintaining, i don't find idea to fix this error.

Ive recently switched over to AT&T Uverse TV/Internet service and I've noticed that when I ssh into my linux( 2.6.18-194.3.1.el5xen CentOS) server I get disconnected. When I'm using putty it gives the "network error software caused connection abort" error. When I'm at work using one of our jump servers and ssh'ing from the command line it will freeze up from time to time but never disconnects. I think the problem is either with the OS or the new AT&T modem. At first I had my CentOS server using DHCP and it would disconnect within a few minutes after I ssh'ed. I switched over to a static IP and now it goes about 10 minutes before it disconnects. It doesnt matter if I'm actively typing or not, so it's not an inactivity issue. I have the firewall turned off on my laptop, and since the issue happens on multiple devices, including my iphone I dont think thats the issue.
I have iptables and selinux turned off/disabled so thats not it. In putty I have enabled Keep Alive(30 seconds) and it still disconnects. I opened the port on the modem to allow ssh for the IP of the linux server. Ive also recently reinstalled this server with CentOS so I can't compare with the previous internet provider as I didn't reinstall until after I switched over. BUT previous installs with CentOS 5.2 worked fine with the previous ISP. AT&T Modem is a 2wire 3800HGV-B

I'm at the end of my rope here, and am extremely frustrated. I have a web server running on Ubuntu Server and am using OpenSSH for all my SSH and sftp needs. However, I have the strangest of all situations that I cannot for the life of me figure out.
I have a user chrooted to /var/www/username in /etc/ssh/sshd_config and in /etc/passwd. When the user is chrooted to that folder, whenever I try to log in through SFTP using any client, I get an error saying "Network error: Software caused connection abort." The kicker is, when I chroot the user to /var/www that user can log in just fine. I've tried changing every chmod and chown setting I can think of, and I have NO idea why it matters by one folder.
I had the jail working perfectly for about 2 hours, when it seemingly just decided to stop.What's really getting to me is why the two folders, which have the exact same settings, are not operating the same way.

I just recently installed RT Tracker 3.8.8 on a Centos 5 VM install. I've been running 3.6.6 for more than a year now with no issues. But I'm having some serious slowness issues with 3.8.8. When I start the httpd service at least one of the processors go straight to 100%. It also tends to do this when you browse to it for the first time. I've been trying to figure out the problem, but I can't get a grip on this one. This error pop's up in the /var/log/messages log:
Jun 22 11:03:56 helpdesk RT: Apache2::RequestIO::rflush: (103) Software caused connection abort at /usr/lib/perl5/site_perl/5.8.8/HTML/Mason/ApacheHandler.pm line 1020 (/opt/rt3/bin/webmux.pl:79)

As usual, I let the update manager run.. But now something bad happened and a red button is showing in the system tray, which when I hover my mouse over it, tells me to open package manager or try "sudo apt-get" in terminal to see what is wrong..
If I enter sudo apt-get upgrade, I get the following errors.. How can I fix it.. I am unable to open package manager itself..
Code:
E: Problem parsing dependency Depends
E: Error occurred while processing gconf2 (NewVersion1)
E: Problem with MergeList /var/lib/dpkg/status
E: The package lists or status file could not be parsed or opened.

I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error:
Authentification has failed.
As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.

(I'm probably going to have my forum account revoked due to excessive usage ) I'm setting a VPN connection on openSUSE 11.2. Using the networking icon on the tray I add a PPTP connection, set it up but I receive a message 'VPN connection failed'. Googling it up I tried changing a setting called 'refuse-eap' to 'yes' but it doesn't seem to work. Here's the result from the log file:

I'm having a little problem here. That, or I'm missing the obvious staring me in the face. I have this file server, called toad. I nuked it's system disk, reorganising the partitions and upgrading to openSUSE 11.3 x64. I installed vsftd with "Yast FTP server", and the config looks OK. I even compared it with that of another machine. But when I try to connect, this is what I get:
user@mainmachine:~> ftp
ftp> open toad
Connected to toad.geuens.org.
500 OOPS: could not bind listening IPv6 socket
I'm prettige sure IPv6 is deactivated. The firewall is disabled on both machines. I've looked this over again and again. Can't find it. It's not the connecting machine, I've tried from another.

I have local and remote networks that have various printers. I can add any printer (local or remote) to any PC, except for one PC that's refusing to allow remote connection (it used to, but doesn't now!). The problem PC has two printers connected and work OK as a local printer, but both display same problem when attempting to connect from any remote PC via YaST. Using 'Connection Wizard> CUPS Server' connection method requires IP address of remote PC and printer name. But if I correctly select either of the two printers I get an error message:
"PING 192.168.1.149 (192.168.1.149) 56(84) bytes of data.
64 bytes from 192.168.1.149: icmp_seq=1 ttl=64 time=1.12 ms
Both printers are set to 'Accept Print Jobs' and 'Share Printers> Allow remote access' permits all networks to connect. why this PC is requiring the root password?

I had this issue with Fedora Core 13, so I switched my laptop back to OpenSuse and continued to have the problem. I can do a host lookup for software.opensuse.com and I get a correct response ...
Code:
linux-edxs:/etc # host software.opensuse.org
software.opensuse.org has address 195.135.221.150
linux-edxs:/etc # host download.opensuse.org
download.opensuse.org has address 195.135.221.134
Firefox works. Thunderbird finds my mail servers just fine. SSH works. But then when I try to do anything involving software updates or installation, I get ...
Code:
linux-edxs:/etc # zypper update
Retrieving repository 'Updates for openSUSE 11.3 11.3-1.82' metadata []
Download (curl) error for '[URL]':
Error code: Connection failed
Error message: Couldn't resolve host 'download.opensuse.org'
I've seen others here post queries about this, and I'll tell you what it was in my case: our DSL modem's DHCP server returns its own IPV4 address as the DNS server. When I looked at /etc/resolve.conf, I saw "nameserver: 192.168.50.254" on the last line -- the IPV4 address of our DSL modem. I manually inserted "nameserver" lines for our ISP's two actual DNS servers, and everything magically started working. Why this should confuse some software under Linux, but not other software, is a mystery. It also seems to be Gnome-specific (I didn't have this problem with OpenSuse 11.3 and KDE 4).
Ask if they're using Gnome, and ask them to check resolve.conf. A lot of DSL modems and home/small office routers return their own IP address (i.e., the same as the gateway address) for the DNS server on a DHCP query. The solution is to manually edit resolve.conf and put in your ISP's DNS server addresses manually. Incidentally, just my opinion, but Network Manager needs to make this an option. Under Windows, for example, you can select "automatically assign DNS" or you can enter them manually, even if you're using DHCP. It'd be nice if Network Manager permitted that.

I got connecting to our NAS over NFS working perfectly. Direct NAS Reading & Writing - How? But on Saturday I found out it had stopped working. For no apparent reason, not straight after an update either I don't think. When I manually try to mount --verbose:
mount 192.168.100.14:/IHL /mnt/IHL --verbose
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Tue Jul 6 14:48:32 2010
mount.nfs: text-based options: 'addr=192.168.100.14'
mount.nfs: Unable to connect to 192.168.100.14:111, errno 111 (Connection refused)
mount.nfs: mount to NFS server '192.168.100.14:/IHL' failed: System Error: Connection refused
Corresponding fstab line that used to work just fine. 192.168.100.14:/IHL /mnt/IHL nfs auto 0 0 For now, I can drop back to Samba but this is a PITA as I can't open OpenOffice documents and write to them directly on the NAS. The fact smb://192.168.100.14/IHL works proves networking wise we're cool too. There is no firewall between this PC and the NAS, the NAS is instructed to allow my PC's LAN IP full access. OpenSuse's software firewall has been told to allow NFS Client too. Why would this setup break out of nowhere? How can I debug this best? I see nothing relevant in /var/log/messages How can I get it to work again? A hopeful reboot didn't do its usual wonders...

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?

This computer is using a Linksys WMP54G network adapter, and running Linux Ubuntu 8.10 with all of the latest updates. It was working fine for a couple months, then one day the internet quit working on it. I've tried playing with all of the settings, and can't get it to connect to the network. The windows computers in the house work fine. I also hooked my Linksys WUSB54GS USB network adapter and that worked right away. When I put the WMP54G back in, it will detect the networks but it won't connect. It gives the message, "the network connection has been disconnected", right away. Can someone please help with this. I work doing tech support for a small ISP and am excellent troubleshooting Windows but Linux is another story.

These problems just started the last couple of days but I have been using Lucid 10.04 for a month now. My wireless Signal varies in strength wildly. I sitting at home, not 20 feet from my router. I never had these problems before Ubuntu Lucid Lynx 10.04. I am running both Network Manager and Wicd.
Errors:
1. Wicd states "Wrong Password" which is not true.
2. Dropping off-line for no reason, sometimes 3 or 4 times a minute and sometimes it works fine for hours.
3. Firefox 3.6.3 Automatically Checking "Work Offline"!?

I have the Proper Wireless Drivers. I have not changed my wireless settings, channel or WPA for 8 months now so I know thats not it.

I 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 have a home network with one computer with ubuntu and two laptops with vista and one router. Last month, ubuntu could access files on vista machines and vista machines could access files on ubuntu machine. Everything great. The only change was an update to ubuntu 10.10 in april. After the update, the ubuntu machine can access files as before, but I get "The network name can not be found" the connection has not been restored". What changed in the last update, and what must i do to restore access to Ubuntu files?
