Ubuntu10.04とWindowsXPでNX Free Edition、マイメモその１
http://sourceforge.jp/magazine/07/07/13/0134235を参考。
Ubuntuにサーバーをインストール
本家サイトよりNX Free Edition for Linux*1をDL。
以下の順序(nxclient->nxnode->nxserver)でインストールとのこと。
sudo dpkg -i nxclient_3.4.0-7_i386.deb
CUPS云々とメッセージ出てくるけど無視。
sudo dpkg -i nxnode_3.4.0-14_i386.deb
CUPSどうたらと、WARNINGが出るけど無視。
sudo dpkg -i nxserver_3.4.0-14_i386.deb
終了ステータス 1 を返しましたと、ERRORが出るけど無視できないｗ；
ググってみると、以下の同様の現象が。

回答のとおりに再インストール
最初に削除。
$ sudo apt-get remove nxserver パッケージリストを読み込んでいます... 完了 依存関係ツリーを作成しています 状態情報を読み取っています... 完了 W: Duplicate sources.list entry http://ppa.launchpad.net/freenx-team/ppa/ubuntu/ lucid/main Packages (/var/lib/apt/lists/ppa.launchpad.net_freenx-team_ppa_ubuntu_dists_lucid_main_binary-i386_Packages) W: これらの問題を解決するためには apt-get update を実行する必要があるかもしれません E: パッケージ nxserve が見つかりません
まあ、インストール出来てないのだから削除しようが無いですね。
次はdebファイルの取得だけど、MD5のチェックしているんで
debファイルに問題ないので省く。
で、最後に再インストール。

現象変わずに、またエラーｗ；
と、ERROR通知をよくよく読むと！？(;つД⊂)ｺﾞｼｺﾞｼ
NX> 704 ERROR: Cannot add user: nx. NX> 704 ERROR: User: nx already exists.
userでnxって何(ﾟДﾟ)！？
そんなの作った覚えないんですけど、調べてみる。
$ cut -d: -f1 /etc/passwd …(ry） sshd nx
ああ(￣口￣)ノFreeNXのインストールの時にでも作られたのかな
原因わかったので、早速nxユーザー削除して
sudo userdel -r nx
インストールに再トライ＞＜

NX> 700 Showing file: /usr/NX/share/documents/server/install-notices Server keys The initial login between client and server happens through a DSA key pair, i.e. a couple of specially generated cryptographic keys, called the private key and the public key, which allow you to establish a secure connection, by means of SSL encryption, between NX client and NX server. The public part of the key-pair is provided during the installation of the server, while the private part of the key-pair is distributed together with the NX Client. This ensures that each NX client is able to authenticate to the server and to start the procedure for autho- rizing the user and negotiating the session. If you want to create a virtual private network (VPN) instead, you need to generate a new DSA key-pair and distribute the private part of the key-pair to those NX clients you want authenticated to the NX server. More information on how to generate and distribute a new DSA key-pair is available at: http://www.nomachine.com/ar/view.php?ar_id=AR01C00126 Creating Users NX is configured to allow access from any system user, as long as valid credentials are given to the user for the SSH login. NX pro- vides an alternative authorization method, allowing system admin- istrators to determine which users are given access to the NX fun- ctionalities. This works by implementing a separation between the system password and the NX password, so that, for example, it is possible to forbid remote access to the system by any other means except via NX and use the NX tools to implement effective accounting of the system resources used by the user, or to share NX passwords in an external database. To activate the NX user and password DBs, you will have to edit the NX server configuration file by hand or use the NX Server Manager Web tool available for download on the NoMachine Web site at: http://www.nomachine.com/download-manager.php Session Shadowing and Desktop Sharing The session shadowing functionality allows you to share NX sessions running on the node. The desktop sharing functionality instead, gives access to the native display of the X server as if you were in front of the monitor. By default you can access sessions in interactive mode and upon authorization of the session owner. You can modify this beha- viour by tuning the server configuration according to your needs, for example by allowing access to sessions in view-only mode, or connecting to either a suspended session or the local display via the Desktop Manager login window. Load Balancing NX Advanced Server provides support for multi-node capabilities and load balancing. In its current implementation, NX server can only manage accounts on the host machine, so to grant access to the node running remotely, you will need to create the user account directly on the remote node host by issuing the NX node commands as root user. You will also need to add the NX Server public DSA Key to the node to allow this server to connect to the node running on the remote host.
