Ubuntu :: Can't Access SSH Remotely But Can Locally

Oct 10, 2010

I've got an SSH server setup on my box which is running locally fine. I can connect to it through my local laptop but when I try to connect through the internet either via my IP or using the DynamicDNS I have setup both get an operation timed out message.I've got firestarter running with an inbound policy to allow connections from any host to port 22. I've also gone into my Netgear router and selected to forward any inbound connections to port 22 to the IP of the box that's got the SSH server on it.

Even with all this the connection just isn't being made. I've also tried temporarily setting the DMZ option on the router to forward all inbound connections to the IP of the Ubuntu box but still get the same Operation time out. Is there any other options that wouldn't allow remote connections via SSH? Or am I missing something hugely obvious here? Maybe it's possible to connect to SSH via a different port or something?I'm running Ubuntu 10.4 and have installed openssh-server via Synaptic. Would be great to get this working so I can use it as a tunnel from work and access the VNC, which I've been told should be done via SSH anyway.

Server :: Vsftpd: Can Connect Remotely But Not Locally?

Jan 31, 2011

I'm running vsftpd-2.2.2 on Slackware 13.1 and I'm behind a NAT with a dynamic IP. I'm using pasv_address, which makes it necessary to have a crontab that checks whether my IP has changed, and if it has, edits the conf and restarts vsfptd. It's hackish but it works. I have also enabled FTPES on the same port that normal FTP runs. I have allowed only the 5001:5003 ports and I am aware that the recommented is 50 ports. However I never had an issue with the transfers since I'm the only user and have at maximum two simultaneous transfers.

I can connect remotely with FTP and FTPES with every client I tried but I'm having issues locally. FileZilla refuses to connect on FTP and FTPES. WinSCP can connect on FTP but not FTPES. Issues are gone if I enable pasv_promiscuous, which the manpage strongly recommends not to use unless "you know what you're doing". I don't. Why is this happening? And, can I fix the local connections without resorting to pasv_promiscuous?

Here is my config and log files from a failed local attempt.

vsftpd.conf

Code:

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022

Server :: SSH Server Can Connect Remotely But Not Locally?

Jun 14, 2011

I'm having issues with my SSH server.The server is running on a Slackware 13.37 machine, using the default SSH server software, which I believe is OpenSSH.On my Windows machine, I've tried connecting to my Slackware machine but can only do so using the external IP, not the LAN IP, instead I get a "Connection Refused" error using PuTTy. I've forwarded port 22 for both UDP and TCP packets to my Slackware machine.I don't really know what information you need so just ask me and I'll respond to the best of my abilities.

CentOS 5 :: Unable To Gain Access To Server Locally?

Jun 30, 2009

We have a server were we no longer seem to be able to gain access, neither locally or remotely.When we try to connect via SSH we get a "Connection Refused". We have checked that it's not our standard firewall blocking the request, so it can either be the local firewall (which we disabled when installing) or that the process isn't running.However, when we try to login locally on the machine (as root) all we get is "Login failed". We've tried restarting the machine in single user mode to change the root password, and while we can do this succesfully, it still doesn't give us access when rebooting the machine afterwards.No other users (besides the standard users created when installing) are available on the server, so we can't say if this is a problem with the root account, or with logging on in general.

General :: FreeNX Can Access The Session That Open Locally On The Server

Sep 24, 2009

I just tried FreeNX. I work great. I am thinking about uninstalling the vino/vnc on my machine.

However, I'd like to know if FreeNX can access the session that open locally on the server. I tried session 0 and 1, none of them can access the local session.

For default vnc, the connection will let you access the local session on the server. Can FreeNX do that?

Ubuntu Servers :: Setup Access Properly From A Public Address To A Monitoring Server That Works Fine Locally?

Apr 19, 2011

I've spent days trying to setup access properly from a public address to a monitoring server that works fine locally. Everything works from public access until I try to link to a CVS repository. The rancid CVS repository is set up as a separate server (virtualhost). It appears the referring link causes a DNS error (105: Server Not Found) when the CVS repository server is accessed from the public address. Things work fine when accessing via localhost.

Localhost link:

[URL]

Public link: (this results in 105 error caused by redirection (bold portion of link))

[URL]

Code:

Virtualhost config:
LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so
JkWorkersFile /etc/apache2/workers.properties
JkLogFile /var/log/apache2/mod_jk.log

Ubuntu :: Unable To Access Either One Remotely Via Transdroid?

Jul 21, 2010

I've been using transdroid on my nexus one to access transmission successfuly for some time now. But transmission is just too limited for what I really want. I really like either deluge or ktorrent and want to use them but this far I haven't been able to access either one remotely via transdroid. I'd greatly appreciate and advice anyone can offer.

I'm at work right now but can go into further details once I get home if need be. I've set up the webui plugin via the preferences menu in ktorrents settings and just can't get transdroid to connect.

Fedora :: Access The Box Remotely?

Sep 7, 2010

I installed JIRA on my Fedora Linux system. Upon enabling ssh, I am able to access the linux machine from a different system. But I am not able to access the port on which the JIRA process is listening to. I usually do http://localhost:8080 from my unix box and I do http:ipadd from another windows machine. But http://ipadd:8080 doesnt work from the windows machine. Do I need to setup something else to access the IP and the port from a Windows machine?

Ubuntu Networking :: How To Remotely Access Samba Share

Dec 19, 2010

My work uses an internal software suite where the data is hosted with a linux server. It uses mysql and samba shares. We are currently opening a new location and need to be able to access the samba shares. We are able to access the mysql databases. The samba shares are used to store various files for the software such as updates, invoices (as pdf files), etc. I've setup vpn connections using windows servers in the past but I can't, for the life of me, get a VPN server setup on our linux server that windows will connect to. I've tried openvpn and pptp. I'd prefer to use the built in windows client to connect.

Ubuntu Servers :: Can't Access MySQL Remotely Via PhpMyAdmin?

Jan 3, 2011

One server is a dedicated MySQL server. After upgrading that one to Ubuntu 10.04 (from an ancient Suse 9.2), both servers are running Ubuntu 10.04 LTS.I have another server that I use to administer the database server via phpMyAdmin. However since the upgrade it is not able to connect. I get an error #1130 Cannot log in to the MySQL server. The same happens if I try to connect remotely from the command line with: mysql -u root -h 129.79.137.121 -pI'm not sure if this is an iptables/ports problem or a configuration problem on the MySQL end or something else entirely.I've searched and tried the suggestions I've found in various places but none seems to have fixed it.

I have won my fight and my father in law accepted to give gnu/linux a try as his server and to run on the computer of the new company he is starting. One feature he would like is to be able to access his work desktop (graphicaly) from home. On my side, I would like to be able to control his desktop from home if I need to show him things. I already can SSH in terminal to install and maintain stuff but, to move the mouse around and point him where to click or what to use would be invaluable.

Red Hat / Fedora :: Want To Be Able To Telnet Into Machine To Access It Remotely

May 11, 2010

I'm a computer technician and I'm interested in learning Linux. I did some research about the different distributions last night decided to try Fedora. I downloaded the latest version of it and installed it onto a brand new machine in my office. Is there a website out there that I can use as a guide for all of the Linux commands. I know that if I wanted to I could just learn my way around the gui, but I want to REALLY learn Linux. I also want to be able to telnet into the machine so that I can access it remotely. How can I set that up? I installed Fedora with all of the default settings and didn't change anything.

Server :: Cannot Access Apache Web URLs Remotely?

Jun 7, 2010

I have a fresh fedora 13 install, I managed to browse and setup my phpadmin.....and browse everthing locally. I can not browse the web site from any other machine in my network. All my machines get their IPs from my dhcp (192.168.1.0).I googled and read a thread in this forum, I understood it might be due to SELINUX. I disabled it, rebooted, still have the same behavior, browse my apache locally but not from other machines. I did a telnet from one of my machines using the IP as followstelnet 192.168.1.11 80got the following onnecting To 192.168.1.11...Could not open connection to the host, on port 80: Connect failed.I checked error-log and access_log file, found no hint. I think it should be something related to some fedora systemor firewall or selinux config that is not allowing access to it.

Fedora :: Access Files Remotely But Remain Secure?

I would like to be able to access my data file that reside on my Linux machine at home from the Internet but I don't want to open any "doors" for lack of a better word that will compromise the security of my files. I am running F11 and I am using cable broadband and a Linksys router.I have been able to get ssh working with OpenSSH while I am at home but I don't really need or want to ssh remotely, I would rather setup what I think is called an ftp. I just want to be able to up and download files to my Linux machine.

OpenSUSE :: Remotely Access Webcam - Home Monitor?

I am wondering if there is a good application that would allow me to setup a webcam at home, so that if I am at work, I could launch an application my android phone (or via a web browser) that would allow me to view & HEAR what is going on. It would also be neat if the application running on the home computer could be smart... ie: start recording if there was a loud noise & send an email alert ... or similar I havent purchased any hardware... but was thinking a (USB) for the main and an additional wireless (w/infrared) for being able to move around.

Servers :: Install - Access It Remotely Via Ubuntu Desktop Environment Instead Of SSH Command Line?

Aug 5, 2011

Is there any way to install a Ubuntu server and access the server remotely via a Ubuntu desktop environment instead of a SSH command line?

I will be installing a Ubuntu server in an office where the office manager will need to be able to do simple things like add/remove users, access filesystems, etc. She can handle these tasks in Ubuntu desktop/GUI, but it is impractical for her to have to learn how to use the CLI terminal to do this stuff.

Will I have to install desktop Ubuntu on the server to do this, or can I install Ubuntu server version and setup another computer Ubuntu desktop to remotely login graphically?

Fedora :: Way To Remotely Access Work Station Running Windows XP

Oct 5, 2010

I run Fedora 13 on my HP dv6000 Pavillion. I am looking for a way to remotely access my work station running Windows XP from my Fedora machine. Most of the information I found explained how to access a Linux box from a Windows environment, and the one place I found that showed the other way around was incomprehensible.

Our company servers run Windows XP, and we have successfully installed remote desktops on other laptops running Windows.I thought of running the remote desktop from a Virtual Machine Windows session, but it seems a cumbersome way to do it.

General :: Connect And Access Files Remotely To Samba Server Over Internet

May 31, 2010

I have a server at home running as a file server and DHCP connected to a switch with a wireless AP in there as-well. with this setup I can access the files and do some configurations via SSH on the actual server anytime I'm able to get the wireless signal, now lately I felt the need to be able to do the same but this time over the internet. I've read somewhere already that I'm gonna need a router with port forwarding and NAT, then know the IP address of the server but my problem is once you start talking about routers then you need broadband connection which is something I don't have. Getting a router is not much of a problem but without ADSL like connection I guess its useless, what do I need to do?
