• Why is exec-shield protection not on by default? (What are the pros of having it off?)

  - by Josh

  I am working in CentOS 5, I was wondering why exec-shield isn't on by default? I found a bunch of articles on how to enable and disable it as well - but nothing answering why anyone would want it off. Any cons to turning it on?

• How do you delete a directory you don't own in an NFS directory you do?

  - by John Ellinwood

  There should be a simple answer to this, but I can't find it. ~me/work>ls -la drwxrwxr-x 3 me mygroup . drwxrwxr-x 3 me mygroup .. drwxrwxr-x 3 me mygroup folder1 drwxr-xr-x 3 person2 mygroup folder2 This is in my home directory, which is an automounted NFS. Somebody in my group created folder2 in my home directory and then left for vacation. I can't delete the folder... I can't move it... can't change permissions on it. How can I get rid of it? My sysadmin has no clue.

• Why does Exim puts emails on hold if there are frozen messages in the queue?

  - by user51932

  Hi, I've a CentOS with CPanel server working as a SMTP server, which currently uses 20 different hostnames and IP addresses to deliver email for an email newsletter service. However, it's extremely slow in sending emails. It's sending like 10 emails per minute, which I check by running the "exim -bpc" command. What could be affecting this? One thing I'm supposing, is that there are frozen messages in the queue, which are slowing down the sending until they're sent out, and are putting new messages on hold. What are the most common reasons a message can get frozen? Also, would it be more efficient to use 20 different small VPSs to send out email rather than use one large VPS with the 20 different hostnames and IPs in it?

• Redirect websockets to port?

  - by DigitalMan

  So, I've got a WebSocket server in C++, that is a completely stand-alone entity - handles header parsing, receiving, sending, all of it on its own, listening directly to the port. Problem is, it needs to run on a server alongside Apache, and that's a bit of a problem. Now, there was a solution here to a similar issue involving mod_proxy, but I'm hoping I can intercept and redirect WebSocket communication before Apache even knows about it, possibly with iptables. So the question is, is it possible to direct traffic bound for chat.mysite.net to a WebSocket server on, say, port 8080, while anything else headed to mysite.net proceeds as expected to Apache?

• Access denied for user 'root@localhost' (using password:NO)

  - by murgatroid99

  I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

• Setting thresholds via smartd.conf

  - by JPerkSter

  Hello! We currently use smartd to monitor SMART health on our disks. I would like to set the 'thresholds' that smartd uses to report. For example: 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 9 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 9 I would like to be able to set a threshold for these two attributes to only report if they are above 10. I haven't been able to find a way to set this via smartd.conf, and I'm also not looking to actually shutdown the daemon. Has anyone ever tried this, or know how I might be able to accomplish this better then throwing a script into cron.hourly?

• Why does changing a truecrypt password take such a long time?

  - by Alex

  I am changing the password of a truecrypt file container. This takes around 1 minute. Why? time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null" If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password: open("/dev/urandom", O_RDONLY) = 6 read(6, "\36&{\351\212\212\343\202\34\313\242\312I\326\235\245\224\300\354O)\270Q\200 \201J\227\224\311_\212\367"..., 640) = 640 close(6) = 0

• Can I use Cygwin as a replacement for Ubuntu, for bash script testing?

  - by Jeroen De Meerleer

  Next wednesday i'm having an exam on Operating Systems. In this exam there will also be a part bash-scripting. The teacher itself will test the scripts in a Virtual Machine running Ubuntu. Myself, however, I'm having serious troubles with running the latest Ubuntu (14.04 LTS) on a Virtual Machine (there are troubles with gnome running very slow). So I'm thinking about using Cygwin, which is doing the job great for another course. The teacher already confirmed I can use that, but I'm thinking he doesn't know it at all. I've already tested the scripts we made in class and they're all running without errors. But I'm quite sure there are some things I have to mind on. My question: would you use Cygwin as a replacement for the Ubuntu VM? Or should I stick it with the VM (maybe by using a different config/platform).

• Availability of big files on multiple servers

  - by Imises

  I have to handle many (1'000 - 30'000) big files ranging from 200MB up to 2GB. The demand for these files is variable (0 - 300 downloads / file). This is why a single file must saved on 2 or more servers. My servers are placed in different datacenters (France), with different size HDDs (750GB to 4TB). Currently I share the files using PHP and ncftpget / ncftpput, but it's very slow. I need a solution to handle balancing these files across 7+ servers.

• SSH not working after installing SVN server on Debian

  - by sLIDe

  Today I had to install SVN server on my Debian server. I used this tutorial (only I didn't do anything to connect to SVN through file://, http:// or https://, only svn:// and svn+ssh://). After I installed SVN server and configured it after that tutorial, I tried to connect to it. I could connect to it using svn:// protocol, but when I tried to connect using svn+ssh:// protocol, my servers SSH stopped responding. Even after I stopped SVN server and restarted SSH server I can't connect to it.

• How to reduce Fedora's disk size in VMware player.

  - by user428862

  I'm new to Fedora 14, vmware player. After getting Fedora up and running in VMware player. The disk size was 2.7 GB. After three hours of working with it, the disk size has bloated to 4.3 GB. I havent added software to account for the near doubling in size. How do I reduce the size back to 2.7GB range or lower. Im new to Fedora and superuser controls. Im removing more software than adding software. Is this a VMWARE problem or Fedora problem?

• How to securely control access to a backend key server?

  - by andy

  I need to securely encrypt data in my database so that if the database is dumped, hackers are unable to decrypt the data. I'm planning on creating a simple key server on a different machine, and allowing the DB server access to it (restricted by IP address on the key server to permit the DB server). The key server would contain the key required to encrypt/decrypt data. However, if a hacker were able to get a shell on the DB server, they could request the key from the key server and therefore decrypt the data in the database. How could I prevent this (assuming all firewalls are in place, DB is not connected directly to the internet, etc)? i.e. is there some method I could use that could secure a request from the DB server to the key server so that even if a hacker had a shell on the DB server they'd be unable to make those same requests? Signed requests from the DB server could make issuing these requests less trivial - I suppose that'd help increase the amount of time it'd take to compromise the key server, something a hacker probably wouldn't have much of. As far as I can see, if someone can get a shell on the DB server everything's lost anyway. This could be mitigated by using one key per data item in the DB so at least there's not a single "master" key, but multiple keys that the hacker would need to access. What would be a secure method of ensuring requests from the DB server to the key server were authentic and could be trusted?

• Question about conditions of vps host provide

  - by baobeiii

  Looking into buying a VPS from a company. In their terms of service it says: User may not: a) Use 25% or more of system resources for longer then 90 seconds. There are numerous activities that could cause such problems; these include: CGI scripts, FTP, PHP, HTTP, etc. So basically your only allowed to use a 1/4 of what your paying for? Anyone know if this is a standard restriction for most hosting providers? Seems a bit ridiculous but i don't know whats normal in the server world. And the weird thing is they only sell xen servers so why can't i use my allotted resources as no-one else can. Thanks.

• Using u32 together with extension headers (how to jump over them?)

  - by bortzmeyer

  I'm trying to filter on some parts of the payload, for an IPv6 packet with extension headers (for instance Destination Options). ip6tables works fine with conditions like --proto udp or --dport 109, even when the packet has extension headers. Netfilter clearly knows how to jump over Destination Options to find the UDP header. Now, I would like to use the u32 module to match a byte in the payload (say "I want the third byte of the payload to be 42). If the packet has no extension headers something like --u32 "48&0x0000ff00=0x2800"` (48 = 40 bytes for the IPv6 header + 8 for the UDP header) works fine, If the packet has a Destination Options, it no longer matches. I would like to write a rule that will work whether the packet has Destination Options or not. I do not find a way to tell Netfilter to parse until the UDP header (something that it is able to do, otherwise --dport 109 would not work) then to leave u32 parse the rest. I'm looking for a simple way, otherwise, as BatchyX mentions, I could write a kernel module doing what I want.

• SSH + SAMBA + LDAP question

  - by Mejmo

  Hi, I have SSH + LDAP working (I can log to Server2 with credentials from LDAP server Server1). Now, I would like to add Samba server (Server3) and it would be nice if it authenticates the users like Server2. How can I achieve this ? As I see Samba schema and the schema used for storing Unix users are different. So if I change password in Samba schema, I would be able to log in with the old password. I need centralized storage of username/passwords. If I change it once in phpldapadmin, it means for samba and ssh. Thanks.

• Is there a proper way to clear logs?

  - by John H.

  I was wondering if there was a proper way to clear logs in general? I'm new to Ubuntu and I'm trying to set up Postfix. The log in question is /var/log/mail.log. I was wondering if there was a correct way to clear it, rather than me going in it and deleting all the lines and saving it. I find that sometimes errors don't get written to it immediately after I clear the log and save it. Side note: I'm having trouble setting up Postfix and am trying to make it easier for me to read the logs hoping it can help me out, instead of having to scroll all the way down.
