  • Apache Probes -- what are they after?

    - by Chris_K
    The past few weeks I've been seeing more and more of these probes each day. I'd like to figure out what vulnerability they're looking for but haven't been able to turn anything up with a web search. Here's a sample of what I get in my morning Logwatch emails: A total of XX possible successful probes were detected (the following URLs contain strings that match one or more of a listing of strings that indicate a possible exploit): /MyBlog/?option=com_myblog&Itemid=12&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 /index2.php?option=com_myblog&item=12&task=../../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 /?option=com_myblog&Itemid=12&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 301 /index2.php?option=com_myblog&item=12&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 //index2.php?option=com_myblog&Itemid=1&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 This is coming from a current CentOS 5.4 / Apache 2 box with all updates. I've manually tried entering a few in to see what they get, but those all appear to just return the site's home page. This server is just hosting a few Joomla! sites... but this doesn't seem to be targeting Joomla (as far as I can tell). Anyone know what they're probing for? I just want to make sure whatever it is I've got it covered (or not installed). The escalation of these entries has me a bit concerned.

  • How to protect myself from promiscuous mode?

    - by Rivari
    I have read that some network adapters can switch to promiscuous mode and get all the packets sent by my router. We have multiple computers here connected to the same router. They all have the WEP key for authentification. So basicaly, this means that anyone of them, using the promiscuous mode, can see all the packets destined to others computers? That's frightening. How can I prevent this?

  • uninstall mysql on linux with plesk

    - by Arsenal
    I'm having trouble uninstalling linux on my centOS 4 that has plesk. I'm actually trying to upgrade my Mysql 4.1 version to Mysql 5.0 using the following command: yum update mysql I get an error list of conflicted files however. When I try to remove mysql 4.1 and perform a clean install but when I use yum remove mysql* It deletes all of its dependencies and appearantly some of these are files needed by plesk, which causes my plesk to stop working. A did a full restore and everything is okay now, but how can I remove mysql without ruining plesk? I have also tried: rpm -qa | grep mysql to get a list of all files and remove them one by one, but there's a duplicate in that list, so I can't delete those (because it says it doesn't know which one to take). Any help would be greatly appreciated!

  • How to send a batch file by email

    - by MikeL
    Trying to send a batch file as an email attachment, I get the following error: mx.google.com rejected your message to the following e-mail addresses: [email protected] mx.google.com gave this error: Our system detected an illegal attachment on your message. Please visit http://support.google.com/mail/bin/answer.py?answer=6590 to review our attachment guidelines. q42si10198525wei.6 Your message wasn't delivered because the recipient's e-mail provider rejected it. This also happens if I place the batch file in a .zip archive. I need to send a batch file to everyone at my company for them to run, preferably without having to change file extensions first. Is this possible by email?

  • MDADM RAID5 array showing as CLEAN FAULTY

    - by Dean Reilly
    A drive dropped out of my raid 5 array yesterday. It looks like the reason was due to a bad controller so I switched it out and attempted to re-add the drive but mdadm claimed it couldn't do it. So I zerod the superblock and just added the drive normally and left it to resync. When I came to check on the array this morning I was unable to mount it at all and it's now showing as CLEAN FAULTY with two drives missing. The two missing drives are listed as spare and faulty spare. Is there anything I can do in this situation or is the array gone?

  • How can I get a virus by just visiting a website?

    - by Janet Jacobs
    It is common knowledge that you can get a virus just by visiting a website. But how is this possible? Do these viruses attack Windows, Mac and Linux users, or are Mac/Linux users immune? I understand that I obviously can get a virus by downloading and executing a .exe in Windows but how can I get a virus just by accessing a website? Are the viruses programmed in JavaScript? (It would make sense since it is a programming language that runs locally.) If so, what JavaScript functions are the ones commonly used?

  • My server appears to have been hacked+ scanssh run by zabbix is it normal?

    - by Niro
    I'm running a few EC2/Scalr instances with zabbix monitoring. I received complaints about one of my servers port scanning other servers. the logs show it is accessing port 22 on consecutive IP addresses. I looked at the processes list and saw scanssh is running under the user Zabbix. My question is- Is scanssh part of zabbix? Is it suppesd to run? I have active autodiscovery on zabbix but it is looking at another IP addresses and definately not port 20. Is it possible that something in the config of zabbix agent is controlling it and not the settings on zabbix server? What can I do to find out if zabbix is somehow misbehaving or it is a hacker? Any advice is highly appreciated.

  • Free alternative to Audio Hijack Pro?

    - by Tim Visher
    I'd like to record what I hear coming out of the main audio jack on my Mac. Nothing fancier than that. I'm aware of Audio Hijack Pro but that really does much more than I'm looking for and comes with a steep price tag. If it's the only tool that can do the job that's fine but I was hoping to find something that simply captured all audio coming from the computer and dumped it to a file. Any suggestions?

  • Old laptop turns off due to overheating

    - by Jake Thomas
    I have an old Laptop that powers off when the processor's temperature exceeds 84degs Celsius. The more annoying part is flash causes this the most of the times. If I watch a web feed for more than 15-20mins, it results into hard shutdown of the machine. I have an idea of a could-be solution to this problem, I want a program that would decrease the processor's clock speed to about 1.2GHz or whatever, leading it a lower temperature. Is there a program out there that does this? P.S. Someone please edit this and add the relevant tags, as I'm new and i have no idea of what tags to choose from.

  • Ubuntu server; Backup of server and MySql database, and Solr database

    - by Camran
    How is backup done on ubuntu servers? I have a server (Ubuntu 9.10) which has apache2 installed, php5, mysql etc... The website is a classifieds website where all classifieds are stored in mysql and Solr. I need to backup this server with all information to be able to fully restore it if something goes wrong. How should I start? Is it an automated task, or will I do backups manually? (prefer manually) Thanks

  • What could cause these "failed to authenticate" logs other than failed login attempts (OSX)?

    - by Tom
    I've found this in the Console logs: 10/03/10 3:53:58 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:53:58 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). 10/03/10 3:54:00 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:54:00 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). 10/03/10 3:54:03 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:54:03 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). There are about 11 of these "failed to authenticate" messages logged in quick succession. It looks to me like someone is sitting there trying to guess the password. However, when I tried to replicate this I get the same log messages except that this extra message appears after five attempts: 13/03/10 1:18:48 PM DirectoryService[11] Failed Authentication return is being delayed due to over five recent auth failures for username: tom. I don't want to accuse someone of trying to break into an account without being sure that they were actually trying to break in. My question is this: is it almost definitely someone guessing a password, or could the 11 "failed to authenticate" messages be caused by something else? EDIT: The actual user wasn't logged in, or using a computer at the time of the log in attempts.

  • Afraid computer is not secure

    - by Michael James
    I have recently implemented LastPass as a secure password manager. When I changed the password for my email address an associated account ([email protected]) that i had never seen before came up in association with my account. It asked me if i wanted to change password for my account and the "smithfaketester" account I used Google to try and find out what is going on, but came up empty. I am afraid my computer is bot net-ed. Any input is greatly appreciated. I have used google to search for reasons why this fake account was coming up but I did not find any meaningful info.

  • Malicious content on server - next steps advice [closed]

    - by Under435
    Possible Duplicate: My server's been hacked EMERGENCY I just got an e-mail from my hosting company that they got a report of malicious content being hosted on my vps. I was unaware of this and started looking into it. I discovered a file called /var/www/mysite.com/osc.htm. Soon after I discovered some weird php files wp-includes.php and ndlist.php both recognized as being PHP/WebShell.A.1 virus. I removed all these files but I'm unsure of what to do next.

  • Firewall Deep Inspection Updates and Antivirus Subscription, worth it?

    - by msemack
    I realize that this is a subjective question, but I'm trying to get some experiences We have Juniper firewalls in our organization (SSG-320M, SSG-5, and some old NS-5GT). We have the option of a yearly subscription for: Deep Inspection Signature Updates Juniper-Kaspersky Antivirus I seem similar services available from other Firewall vendors. We have Symantec Endpoint Protection deployed to all workstations and servers, plus a dedicated appliance for e-mail spam/virus filtering. So, I'm not sure what these firewall-base services will bring to the table that I don't already have. I would appreciate some feedback from people using these firewall services (Juniper or otherwise). Are these services generally worth it? Do they really catch anything? Do they interfere with normal traffic (false positives)?

  • Router reporting failed admin login attempts from home server

    - by jeffora
    I recently noticed in the logs of my home router that it relatively regularly lists the following entry: [admin login failure] from source 192.168.0.160, Monday, June 20,2011 18:13:25 192.168.0.160 is the internal address of my home server, running Windows Home Server 2011. Is there anyway I can find out what specifically is trying to login to the router? Or is there some explanation for this behaviour? (not sure if this belongs here or on superuser...)

  • Recommended offline on-demand virus scanners

    - by ashh
    I have never run full anti-virus on my Windows XP systems. Instead I use various anti-malware tools to manually perform scans every few weeks. This approach, combined with Windows updates and general care about what web-sites I visit and what files I download has kept me 99% free of problems. The remaining 1% has occurred when I download files that I know may contain malware, but still decide the risk is worth it. When on 2 occasions in 10 years I did get caught doing this, I realised that being able to easily scan them would most likely have avoided getting infected. I don't need, or want, to run a "stay resident" anti-virus. Also, the online scanners such as Kaspersky etc limit uploads to small files, so these are not always useful. In summary I would like to simply be able to download a file and then manually initiate an on demand anti-virus scan, on the downloaded file only. I'm sure some/most Anti-Virus do both, however once again I don't really want to pay for or need the stay resident part. Any recommendations (commercial or free)? UPDATE: This is not an exact duplicate, nor a possible duplicate. I searched for and read other questions on anti-virus here at SuperUser and found none that answered my question. I am specifically asking about anti-virus scanners that run ON-DEMAND locally on the computer, not online scanners.

  • Good Windows shell replacement [closed]

    - by Jazz
    I'm looking for a shell replacement for Windows, instead of Explorer. The features I'm looking at are: a task bar a tray bar an application launcher (I mostly use Launchy for that, but I need a launcher for those applications I forget the name...) The lighter and the easier to configure, the better! I'm currently using Emerge, but I found it a little buggy. I tried many others, but I never found something convincing.

  • Looking for something like Google's Picasa [closed]

    - by Skizz
    I almost like Picasa, but there are two issues that irk me and I wondered if anyone knew of an application that does what Picasa does but without the following problems: Network drives. Picasa is hopeless with network drives. Ideally, I'd like photos to be stored remotely and thumbnail databases to be stored locally with a client-server set-up to update client databases. The main aim is to get updates propagated to clients efficently, reduce network bandwidth and have quick browsing on the client. It needs to be snappy when used over a wireless network. This is just a minor point but the folder view looks awful, especially when it uses those tiny thumbnails. (Also, what is it with folders being drawn vertically. Having spent years looking at folders orientated horizontally, turning them on their side looks so wrong.)

  • iptables ACCEPT policy

    - by kamae
    In Redhat EL 6, iptables INPUT policy is ACCEPT but INPUT chain has REJECT entry in the end. /etc/syconfig/iptables is as below: *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT Do you know why the policy is ACCEPT not DROP? I think setting DROP policy is safer than ACCEPT in case to make mistake in the chain. Actually the policy is not applied to any packet: # iptables -L -v Chain INPUT (policy ACCEPT 0 packets, 0 bytes)

  • iptables -- OK, **now** am I doing it right?

    - by Agvorth
    This is a follow up to a previous question where I asked whether my iptables config is correct. CentOS 5.3 system. Intended result: block everything except ping, ssh, Apache, and SSL. Based on xenoterracide's advice and the other responses to the question (thanks guys), I created this script: # Establish a clean slate iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT iptables -F # Flush all rules iptables -X # Delete all chains # Disable routing. Drop packets if they reach the end of the chain. iptables -P FORWARD DROP # Drop all packets with a bad state iptables -A INPUT -m state --state INVALID -j DROP # Accept any packets that have something to do with ones we've sent on outbound iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT # Accept any packets coming or going on localhost (this can be very important) iptables -A INPUT -i lo -j ACCEPT # Accept ICMP iptables -A INPUT -p icmp -j ACCEPT # Allow ssh iptables -A INPUT -p tcp --dport 22 -j ACCEPT # Allow httpd iptables -A INPUT -p tcp --dport 80 -j ACCEPT # Allow SSL iptables -A INPUT -p tcp --dport 443 -j ACCEPT # Block all other traffic iptables -A INPUT -j DROP Now when I list the rules I get... # iptables -L -v Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 DROP all -- any any anywhere anywhere state INVALID 9 612 ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED 0 0 ACCEPT all -- lo any anywhere anywhere 0 0 ACCEPT icmp -- any any anywhere anywhere 0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:ssh 0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http 0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:https 0 0 DROP all -- any any anywhere anywhere Chain FORWARD (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 5 packets, 644 bytes) pkts bytes target prot opt in out source destination I ran it and I can still log in, so that's good. Anyone notice anything major out of wack?

  • Windows XP: Consequences of setting a password for an account

    - by sleske
    I do not quite understand how Windows (specifically Windows XP) handles accounts with/without passwords. As far as I can see, on a fresh Windows XP install I have one default account which has admin rights does not have a password will auto-login (without password prompt) when the computer boots What happens if I set a password for this account? Will it still auto-login? Or will it always prompt for the PW? And generally, what consequences does it have if I set a password? I noted that Scheduled Tasks apparently cannot run under an account w/o password (creating a scheduled task will prompt for the account PW). Is there anything that will not work with a password set? Why is it even possible to have accounts without a password? I have some Unix/Linux background, but the concepts appear a little different under Windows.
