  • Nexus functionality is limited after installation

    - by Dmitriy Sukharev
    I have a CentOS based server with Sonatype Nexus 2.0.4-1 installed. The issue is that there are no standard "Artifact Search", "Advanced Search", "Browse Index", "Refresh Index" Nexus features, as well as Artifact Information tab after selection of any artifact (only Maven Information tab). I tried to Google, but was amazed that there're no information about this issue. Actually it looks like all actions I've done are: wget http://www.sonatype.org/downloads/nexus-2.0.4-1-bundle.tar.gz tar -xvf nexus-2.0.4-1-bundle.tar.gz cp -r nexus-2.0.4-1 sonatype-work /opt/ ln -s /opt/nexus-2.0.4-1/* /opt/nexus ln /opt/nexus/bin/nexus /etc/init.d/ chmod 755 /etc/init.d/nexus vim /etc/init.d/nexus NEXUS_HOME=“/opt/nexus” RUN_AS_USER=“nexus” useradd -s /sbin/nologin -d /var/lib/nexus nexus chown -R nexus /opt/nexus/ chown -R nexus /opt/nexus-2.0.4-1/ sudo -u nexus cp /opt/nexus/conf/examples/proxy-https/jetty.xml /opt/nexus/conf/ To force Nexus be available through HTTPS I went to Administration - Server - Application Server Settings as admin and changed Base URL to https:// external IP/nexus and set Force Base URL to true. Any ideas how to get missed Nexus features?

  • ls returns nothing only in certain directories

    - by Jakobud
    I have a raid drive mounted here: /data/ And certain directories like this one: /data/somedir/somesubdir/ when I run ls w/ or w/o any flags, terminal doesn't return anything. It does not return an empty directory listing. It simply goes to the next line and sits there blank with no prompt coming up. I cannot CTRL-C out of it. I have to close this terminal instance and start over. At first I thought it was something to do with the ls command, but its pointing to /bin/ls and I can ls other directories just fine. Also, running this find /data/somedir/somesubdir immediately finds all the files just as expected.

  • Limit rate of outgoing UDP packets per second

    - by tim82
    Hi, since Teamspeak version 3 sends lots of packets per user and our provider is getting problems with his infrastructure above 20.000 packets per second we have to limit it that our servers are not going to be shut down. Red a lot about iptables but was not able to find the right rules. Could you give me an advise how to manage that the server is not going to send more than 19k packets per seconds? We are running on debian 4 Thanks in Advance Tim

  • Creating a ssh tunnel to transfer files?

    - by Vincent
    For me, networks are a very "opaque" thing, and even with reading a lot of tutorial about SSH, I do not understand how to create a basic tunnel to transfer my files. The configuration is the following : My Computer --[Internet]--> Bridge Machine --[Local Network]--> Final Machine Currently I do the following : 1) Connect to the Bridge Machine with : ssh -X [email protected] 2) Connect to the Final Machine with : ssh -X username@finalmachine 3) I copy the address of files I need (for example .../mydirectory) 4) Then I deconnect from the finalmachine with : exit 5) I copy the files to the bridge : scp -r username@finalmachine:/.../mydirectory . 6) I deconnect from the bridge with : exit 7) I copy the files to my machine : scp -r [email protected]:/.../mydirectory . Which is quite complicated. My question is basic : how to simplify this using a SSH tunnel ? (and please explain me the signification of each command line you write, to understand what each line really do and to avoid to use it like a magical thing. Furthermore if some ports number are used, explain me if I can pick a completely random number or if I have to choose a specific one.)

  • Windows 7 doesn't boot when second hard disk is connected

    - by kenshin9786
    I'm sorry for my bad english on beforehand. I have two hard disks, one SATA and another IDE. I have windows XP and 7 on the SATA one, and Ubuntu on the IDE. Both of them boots and works, bios recognizes them, just works. After I installed Windows 7, and connected the IDE drive, it freezes on "Starting Windows" (the black screen with the Windows logo). I unplug the IDE drive, and it starts normally. Windows XP starts normally on both situations (with or without the IDE one connected), same for Ubuntu (it works with both disks connected or just the IDE where it is). The IDE drive is on good status according to SMART. The IDE is first on boot order. It goes to the Ubuntu's grub first, then by default it goes to the Windows 7 bootloader, and then to XP. I think the problem is not about the bootloader or grub. I just read that it can be solved formatting the "problematic" hard disk because Windows 7 cannot handle so many active partitions or something like that. But that's not an option for me, I don't want to lose my Ubuntu nor have it unbootable. How can I solve this without this consecuences I mentioned? Any help would be appreciated.

  • Redirecting program errors to both log and error file

    - by Gnanam
    I've a Java standalone program scheduled to run as cron at every 10 minutes I want to catch/write errors thrown by this Java program both in the log file and also as a separate error file (MyJavaStandalone.err).

  • sendmail Name server timeout

    - by broody
    Complete sendmail newbie here... I've been trying to get mailing to work in PHP and I've root caused it down to sendmail's complaint about "Name server timeout": >sendmail -t -v >From: [email protected] >To: [email protected] >. gmail.com: Name server timeout [email protected]... Transient parse error -- message queued for future delivery [email protected]... queued So it sounds like a DNS issue? But I can do a "dig mx gmail.com" and it will query successfully. Here's what confuses me... I can get sendmail to work two other ways. The first way is through telnet: >telnet 127.0.0.1 25 >Helo me >Mail from: [email protected] >Rcpt to: [email protected] >. message sent And the second way is by explicitly appending the sendmail.cf, but this is strange because it's the exact same file I use to configure sendmail to begin with: >sendmail -t -v -C/etc/mail/sendmail.cf But none of these solutions will resolve my PHP mailing... I am clueless as to what is going on... appreciate any help.

  • How to execute with /bin/false shell

    - by Amar
    I am trying to setup per-user fastcgi scripts that will run each on a different port and with a different user. Here is example of my script: #!/bin/bash BIND=127.0.0.1:9001 USER=user PHP_FCGI_CHILDREN=2 PHP_FCGI_MAX_REQUESTS=10000 etc... However, if I add user with /bin/false (which I want, since this is about to be something like shared hosting and I don't want users to have shell access), the script is run under 1001, 1002 'user' which, as my Google searches showed, might be a security hole. My question is: Is it possible to allow user(s) to execute shell scripts but disable them so they cannot log in via SSH?

  • How can I pass environment variables to a WSGI script, using uWSGI?

    - by orokusaki
    I've added the following line to /etc/environment: FOO_DEPLOYMENT_ENV="vbox" Upon logging in via SSH, I can echo $FOO_DEPLOYMENT_ENV and, of course, see vbox output to the shell. If I open a Python shell and run os.getenv('FOO_DEPLOYMENT_ENV'), it will return 'vbox', but the same code in my Python application, when run by uWSGI (as the www-data user), it does not see the environment variable. Clearly, this isn't a problem of uWSGI, and is rather a problem with my understanding of environment variables, or how they're properly set, and the contexts in which they can be retrieved. What am I doing or understanding incorrectly?

  • How to prioritize openvpn traffic?

    - by aditsu
    I have an openvpn server, with one network interface. VPN traffic is extremely slow. I tried to do traffic control with this configuration (currently): qdisc del dev eth0 root qdisc add dev eth0 root handle 1: htb default 12 class add dev eth0 parent 1: classid 1:1 htb rate 900mbit #vpn class add dev eth0 parent 1:1 classid 1:10 htb rate 1500kbit ceil 3000kbit prio 1 #local net class add dev eth0 parent 1:1 classid 1:11 htb rate 10mbit ceil 900mbit prio 2 #other class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 1000kbit prio 2 filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 1194 0xffff flowid 1:10 filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match ip dst 192.168.10.0/24 flowid 1:11 qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 qdisc add dev eth0 parent 1:11 handle 11: sfq perturb 10 qdisc add dev eth0 parent 1:12 handle 12: sfq perturb 10 But it's still extremely slow. I have an imaps connection that keeps transferring data continuously (I successfully limited the rate) but with openvpn I can't seem to get more than about 100kbit/s The internet connection speed is about 3mbit/s (symmetric) What could be the problem? Does the sport filter work for udp?

  • Is using Capistrano for user maintenance tasks on university lab feasible?

    - by danielkza
    I've been looking around for tools to replace some legacy scripts for creating and maintaining accounts in a university computer lab ecosystem consisting of things like: LDAP and Kerberos for authentication User home storage and web pages Entries on an SQL database Printing quotas Mailing lists, etc. I'd also like to automate machine and VM membership for Kerberos and Puppet if possiible. I've found Capistrano, and while the basic principle of running tasks on remote hosts through SSH seems to fit, and the DSL in Ruby looks quite nice, I've found most documentation is related to application deployment, not generic tasks. I'm also not aware of any good way to parameterize tasks so I can pass on the user information for creation. Is something about Capistrano I am missing, or is it not the correct tool for this job? Are there any more userful alternatives?

  • openwrt uses a single interface bridge?

    - by timbo
    My understanding of bridging is that it ties together two interfaces at layer 2. I am looking at a Ubiquiti Nanostation2 running OpenWRT that has an ethernet port 'eth0' and a wifi port 'ath0'. The ethernet port (the 'wan' port) is not part of the bridge and the bridge is just a single interface. Can anyone clarify this? - seems very different to Ubuntu. /etc/config/network: config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'wan' option 'ifname' 'eth0' option 'proto' 'dhcp' config 'interface' 'wifi' option 'ipaddr' '192.168.13.1' option 'type' 'bridge' option 'proto' 'static' option 'netmask' '255.255.255.0' option 'ifname' 'wifi0'

  • Changed login for a user with encrypted home, now I can't login

    - by HappyDeveloper
    I changed a user's login by doing this: $ usermod old_login -l new_login I also wanted to move his home to reflect his new username, but it wouldn't let me, so I just rebooted. But now after I login, the screen blinks and I'm redirected back to the login screen. And that's what happens when you cannot access your home, that's why I think it has something to do with his home being encrypted. How do I fix this? I'm on a Ubuntu 12 Virtualbox VM.

  • FTP User cannot modify files but has correct permissions

    - by Lothar_Grimpsenbacher
    I have created a new user (foo) and when he logs in via ftp he cannot edit the files in the directory to which he has access. In the directory he can log into ls -l gives me: -rw-rw-r-- 1 root www-pub 6427 Nov 17 04:21 index.html The user belongs to the group www-pub. Here is the output of cat /etc/group to demonstrate that he is indeed in that group: ... www-pub:x:1001:ftpuser,www-data,foo foo:x:1002: *edit the permissions on the containing directory are: drwxrwsr-x 5 root www-pub 4096 Nov 17 02:53 thecontainingdir and the one above that: drwxrwsr-x 49 root www-pub 4096 Nov 16 02:40 thenextdirup So since he can log in via ftp and since the file he needs to edit has the correct permissions to let the group www-pub read and write the file and he is a member of that group, why can't he edit it (or upload anything)? Only when I change the file to 777 can he edit it. It's as if he's NOT in the group... but he is! What's going on?

  • What does the -P option do to mount?

    - by Simon
    I'm migrating from an archaic version of Red Hat to Ubuntu 9. When going through my old nfs mount script, I found that it contained the -P option. So my script looks like: sudo mount -t nfs -o -P ... It looks like the -P is one of the -o options. My question is: what does the -P option do? I've searched every man page I can find, with no luck. Could it have to do with privileged ports?

  • Strategies for very fast delivery of webpages.

    - by Cherian
    I run a website Cucumbertown with an initial pay load of nearly 9KB zipped. All my js is delayed loaded with requirejs and modernizer is the only exception. Now all my webpages are Nginx cached and only 10-15% hits go to the backend proxy. And the cache is invalidated by logged in users as proxy_cache_bypass. So for an anonymous user its nearly always a cache hit. I have some basic OS tuning with default via ip dev eth0 initcwnd 15 net.ipv4.tcp_slow_start_after_idle 0 Despite an all cache & large initcwnd my pages still take 2.5 – 3 seconds. I have a yslow score of And page speed at Are there strategies that can help deliver webpages even faster than this? Deliver pages at 1+ second time for 10KB payload? Notes: My servers run of a fairly good data center from Linode at Fremont.

  • Wake On Lan for Fedora 12

    - by Toymakerii
    I have a fedora 12 box that I am using as a sandbox for web development and a few other toys. The box gets really hot so I would like it to sleep/hibernate when no one is using it, however most of the people connecting to the box will not be able to access it physically. Is it possible to set up a Wake On Lan that wakes up the machine when it detects an SSH connection? A google search didn't yield much information. (or atleast I wasn't smart enough to register it as useful!)

  • Free Hosting control panel

    - by John Maxim
    I'm in the mid of researching for one of the best hosting control panels. The server I run is Ubuntu and I have some experience with ISPConfig 2 & 3. Since I haven't explored any others available, what are the recommended ones for an Ubuntu server? I asked because I find that there seems to be some disabling and modifications required for an Ubuntu server if I need to use ispconfig which causes the server to change its actual way of running. It's quite good though, but any more recommended ones ? Something more organic? which doesn't require much breaking and changing. I'm not asking for the simple one, I don't mind going extra mile to install a powerful one but just try sticking with most Ubuntu's conventions will be an ideal one for me. And of course, if there happens to be something that meets the requirement as mentioned "Ubuntu conventions" and also simple to install at the same time, that'd be a bonus. Thanks in advance.
