kumral-linux

i got the point. i check logs it says before connection closed message startkde starting shutdownkde scripts.

then i make nxserver user different from mustafaerhan

then my friend enstablish client and use the connection evertinh is ok. now

i have to make little config for persistent desktop share and interactive desktop.

thnx for all rply again.

PROBLEM SOLVED.

now i did rename the /usr/NX/share/keys/default.****.key to server.****.key rewritten it now

nxserver --checkuser mustafaerhan

nxserver --status

nxserver--restart all is giving no warnings or errors. i did make all authentication or somelikeit working. but now. my client can connect autenticate itselfs after i see a windows nomachine logo on it kde splash screen loading but then before the desktop it disconnects.

it says

"the connection to server was shutdown please check state of your network."

what i have to do ?

i cant understand what u saying?.

but after uninstalling ssh nxserver nxnode nxclient rpms.

deleting /usr/NX directory.

i did install sshserver ssh pam sshguard rpms and nxserver nxclient nxnode rpms .

then i did restart for sshd and

[root@mdv mustafaerhan]# nxserver --install

what must i do ?? i got this just a key auth error. how to correct this ? and i did try webmin but i cant see any NX or FREENX server in webmin.

what ever. i just wantto make this NXSERVERS works without webmin. but thanks for reply.

At all for Ä° want to make remote graphical kontrol of my Mandriva boxPC. Ä° had installed sshd configured. SSH users. my normal system user. mustafaerhan

now i can connect ssh easly everthing works fine. from all internet connected points. PC's.

Now i installed 3 rpm from NoMachine web site. nxserver,nxnode,nxclient, rpms.

edited. /etc/ssh/sshd_config file.

then in konsol as a root tried this.

nxserver --keygen then i coppied /usr/NX/share/keys/default.id_dsa.key to my same machine's same user's desktop. Load it with nxclient app.

then i try this command.

nxserver --useradd mustafaerhan # this user is my standart user. and i can still make connection via ssh i got check this BUT:

i got this.

then i did nxserver --restart it gives good message. at first try before 1 mount ago it was giving start errors. but now it makes restart in order.

when i try connect with client on same machine to my host lan ip after loading key. the window opens that KDE loading splash theme and nomachine logo after that i get messages the connection with the server was shut down. please check your network state.

im readed many docs and find some older or never product distro nx server configs howtos. but i dont have. get it work. and i did try this from out of my lan. with my brother that is in istanbul, Ä°m in izmir.

and this my sshd_config file.

HELP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE :D plz.

yes. i did. in MCC personal firewall enstablishing section.

"select servise to open it to internet." section

but i cant access still.

any other idea ? how to open my server to internet ??

one success for me. (not about server access) i did see mandi is not running on system services and Ä° made it autostart and runing right now i can see scan attack etc blocked ips in Ä°F

and trying to connect again.

.

208.80.194.44 this ip address catched with my Ä°F is that from one of you?

but there is some kind a messup i had closed my apache web server.

and this time Ä°F says this ip trying to connect http servis ?

Hmm finally after resolving mandi daemon and firewall issisue

Ä° can now reach my web server by using another computer. i tested it.

and now my Ä°F is catching some tester friends. while they reaching my web server.

still same ip adress is connected to my web server.

and now im trying ssh and ftp servers to be open.

good night.

problem solved.

Hi peoples.

Ä° have mandriva2008.1 linux distro. im last 3 years Linux user. Ä° want to open server. Like rfbdrake RC machine. Or FTP or Apache web server or ssh2 secure shell connections.

i have made all servers i want

i choose one server for them for server internet connection test.

i choose ssh on port 21 and ftp on port 23 and apache on port 80

i did modem forwarding or port opening for these servers. as listed.

internet outgoing ip is= 81.214.119.130 for a now. local server ip is = 192.168.1.2

and what ever i did i cant connect my mandriva server with ssh or ftp

i used nmap for port test and scan.

i can see bot modem and my mandriva pc 21 80 23 ports are open and i checked port forwarding to my local server.

but still icant connect to my server from internet. when i test servers with local ip 192.16***** they are all working.

but from 81.214.119.130 ip i cant connect to my servers.

mostly ftp says " i found server " after 3-4 seconds message gives couldnt connection enstablished

what can i do for my server up and working

and last thing my interactive firewall now doesnt give any port scan message i did make kernel upgrade and dkms nvidia driver installing.
