I have got openvpn running on my system with certificates and open to the IP addresses 17.xx.xx.x on the server.
What should I definitely block off from the system so that anyone using the VPN cannot gain access and how should I go about this in the firewall?
I'm guessing to block off intranet access to the webserver.
I have mysql and some mail programs running as well - how can I block those off?
After installing Fedora 6 (and probably any later version) I find that access to the add/remove section is denied unless I have an Internet connection which I don't have. I just do not see any reason why this is done this way! One can't even gain access with the DVD Is there a way to circumvent this nuisance from the terminal Does anyone know why this is put into the installation in the first place.?

I just upgraded to Fedora 12 on my computer. Now I can't connect to the net. Under network I show the two connections (neither working). The "connect" and "disconnect" AND the "delete" buttons are all grayed out (?). I also can't log in as root to try to gain more access. Probably just a new way of doing things. I was upgrading from F7 so it was a bit of a jump.
Does the network utility work differently from 7? Am I now rootless? It would seem that my wifi card sees the net as I can see the routers out there, but can't connect. I'm sure I'm using the correct WEP.
I'm the only user, can login (meaning I know my pass). But cannot Sudo. I'm on Ububtu Studio, the latest release. Doesn't make any sense.

View 2 Replies View RelatedWe 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.

I have a friend that recently moved to Linux. She had started out with Ubutnu 9.04, which was giving her a lot of Issues along with being no longer supported, so I recommend Linux Mint 10 to her, since she wanted something closer to Windows. I instructed her on how to do a clean install. Linux Mint installed ok, but when she was about to set up wireless to get on the Internet, she realised that she had forgotten her password. She called her network (Belkin) for assistance to retrieve it. She was told that Linux is not really supported; however they gave her this address to access the router: 192.186.2.1 from her browser which did not work. So there was nothing further they could have done since she couldn't gain access to the router. She is currently only able to use Ethernet connection to get online.
What could she do to reset her password or gain access to the router? I didn't want to tell her to reset the modem in case it will leave her with no internet and no way to setup her router.
I had errors pop up when I tried updating my 10.10 to 11.04 so I ended up having to do it from a Live USB which installs it over everything (fine by me).Unfortunately I forgot I had an encrypted /home directory. So various messages and stuff came up when I tried to log in.nfortunately I don't remember what my encryption passphrase is offhand, so I moved it to a slightly different folder name and had to have a new directory created for my username.It's still there, but how can I try to open it trying the various versions of the passphrase I think it may be? Can I double-click it and try?Also, in the future what is the best way to handle a "fresh" install that I want to connect to my encrypted /home directory?

I recently set up a web server at home, using a non-standard port, due to my ISP blocking 80. I just checked my log files, and I see a TON of entries indicating that a file was not found "proxy-1.php", "proxyheader.php", etc. I do not have these files, not intend to have them as part of my website. I did a whois looking by IP address for several of these, and they all seem to come from an ISP in China. Is there a way to BLOCK any IP address outside the US (that is somewhat simple to do?)

View 3 Replies View RelatedI run my own home server using OpenSuse 11.1, everything is setup using apache, php, etc etc, and it all works perfect, but now I need to use my own email server for the use of Dolphin social networking software, so that when someone registers, the email server sends out registration confirmation emails, so I set up postfix, yeah right!!!, even though I followed all instructions to set postfix as a closed relay, a test done at mxtoolbox site still said it was an open relay, but while I was trying to set up postfix, my access to the server slowed down, and my servers drive light was constantly active,,, so when I look at the mail queue, I saw 4000+ emails, all from japan, (hinen.net), so I promptly shut down postfix and use postsuper -d ALL in the command console to delete the queue, but no matter how I try, I couldn't configure postfix as a closed relay,,, so I uninstalled it and installed sendmail, and using webmin, I could use a spam list and block the domain, now, sendmail's test at mxtools show as a closed relay, I can't even send out a test email using smtp auth, but disabling auth, I can, but now my IP is blocked at spam cop, and spamhaus,,, gmail server say my IP is not authorized to send to their servers, but to use my ISP relay instead,,, but my ISP doesn't have a relay,,hence the need to run my own email server.
My home server uses double layer firewall, a hardware firewall between the internet and the server, and a software firewall on the server, and I only allow the ports I need, IE, 80 = http, 443 = https, 20/21 = ftp, 25 = smtp, 110 = pop3. and that's all, but any other internal access from my workstation to the server, using ssh, I only open the ports on the server firewall. If someone here has a great deal of knowledge on sendmail, and can set up a an M4 (linux.mc) config file for me, it would be much appreciated. What I would like my email server to do, is to only allow the sending of emails from inside it's own server system,, ie, when a php script sends an email to the server, then the email server would let it through, but anything else, outside the local network is ignored.
