Lost connection during install ISPconfig with server

    I was installing ISPconfig after the perfect setup (debian sarge 3.1).

    And somewhere during the beauty of the installscript (I was of to the loo), I have lost connection through putty.

    I did put in the ssl part and passphrase, and somewehre after that i have lost the connection.

    My question is what to do ?

    I can't connect anymore. So do i just restart the machine and do a new install or do I first need to change/delete a few things before doing that.
    Or is it something else i need to do.

    I have done everything through winscp and putty and I am a noob when it comes to commandlines.

    Thanks in advance for the help

    What's the output of
    Code:
    iptables -L
    ,
    Code:
    netstat -tap
    and
    Code:
    ifconfig
    ?

    The results are:

    This is the output:

    iptables -L:

    Chain INPUT (policy accept)
    target prot opt source destination

    And the the same for FORWARD and OUTPUT

    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination


    netstat -tap:

    Hm, looks ok. And now you can't connect to 192.168.100.104 with PuTTY on port 22?

    Is this output after restarting the machine or directyl from console (if you have the possibility to access the machine directly).

    Can you take a look in /var/log/message by the time of the connection broke, if there were any packets on port 22 logged?

    I can connect to the machine

    I can connect now, to the server at 192.168.100.104;

    But I am under the assumption that the script somewhere is hanging and waiting for input (mysqlserver and password etc). So I can't get back in that session.

    The script probably got to the stage where it needs my input. But that never was on my screen (since I lost connection).

    I can reconnect to the machine but do not know how to finalise the script since i am not in that installsession anymore if I reconnect.

    By the way the actual static Ip should be 192.168.100.30 (static IP I set) but
    it has now a IP assigned by DHCP. I don't understand how this happend but its the situation for the moment

    Thanks for your input

    That looks like sth. / sb. changed your networksettings to dhcp at first.

    Why don't you just remove the ispconfig stuff, run screen and reinstall in screen. So if your ssh session brakes you can restart and fetch the screen session

    I am an amateur Ben

    Ben,


    Is this output after restarting the machine or directyl from console (if you have the possibility to access the machine directly).

    This is the output i get in Putty

    Can you take a look in /var/log/message by the time of the connection broke, if there were any packets on port 22 logged?

    No port connections found by me


    By the way I have not restarted the machine yet since I lost connection, because of this thread ( I am installing this machine as an extra testing machine)

    I do have access to the machine directly, and could do just that and had also consirered it allready. But i wanted to make sure I would not mess anything up and start from scratch

    So

    I am happy to reinstall, that's not the issue, I just want to be sure i am doing the right thing and in the mean time learn from it.

    Up till now I have worked with putty and winscp

    When you say screen you mean I should just restart installing ISPconfig from he commandlines on the machine itself ?

    By the way something else ( again i am still learning)

    How do I savely stop (shutdown computer completely) a correctly installed ISPconfigsystem from the commandline ?

    by screen I mean the programm / tool screen.
    with screen you run your shell independent from the access you have to the machine.
    E.g. you compile your kernel which may last 30 minutes or longer. if your connection brakes in between to can not reaccess that session.
    So you could start "screen" do your stuff inside, and recall it with "sreen -r" in case your ssh session broke.

    thanks ben

    Thanks Ben,

    I will have a go with screen.

    I will remove the ISPconfig dir's from the machine as you mentioned and reinstall ISPconfig.


    Thanks for the help.
