[CentOS] How to check for rootkit, troians etc in backed up files?
Hi, there is a remote (VPS) Centos 4.2 server which *may* have been compromised. Reinstalling everything from scratch isn't a problem, it may even be an occasion to improve a few things, the question is another. There are backups of necessary shell script, ASCII configuration files and more or less important email (maildir format, if it matters) including messages with binary attachments in .doc, .pdf, .jpeg and other formats. What is, in the context above, the best way to make sure that **those** backed up files (which _must_ be put back on the server after reinstall) do not contain any rootkit, troian, virus, whatever? Which Centos / linux tool you'd recommend for this specific case? TIA, Marco -- Your own civil rights and the quality of your life heavily depend on how software is used *around* you:http://digifreedom.net/node/84 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Help me
Top posting is when you put your reply on top of the original message, the way I'm doing. Apparently some people prefer that for some reason which dates back to the days of newsgroups. Some people also don't understand that not all clients support bottom posting. Interestingly enough, we use top posting 99% of the time at work, even though it takes extra effort to do so in thunderbird. We had a new employee that started with us, and used bottom posting on some of her replies, and most people thought that her replies were empty. Food for thought, I guess.

Robert, Just got back from my trip and reading that Tutorial, it went on to state what I now find to be two distinct opposite thoughts. Its says at http://iptables-tutorial.frozentux.net/chunkyhtml/c962.html that you shouldn't filter in the NAT Postrouting chain as some streams of packets only have their first packet hit the chain and everything else is redirected hence the possibility exists that some packets can miss the rule. It seems the Filter Forward chain is the safest place to limit what gets masq'ed so internal clients could only have say port 80/443 but no ftp access as an example. What are your thoughts in this?

We shipped the system to them in a moving van (and we prayed it wouldn't be involved in an accident or fire) and they installed it. I never had to go down there. He probably hasn't forgotten the bent floppy either. Attaching the floppies with magnets is also very good. :-) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Help using ed [OT]
Hi Perhaps omeone might answer this tricky problem. I can do this other ways, but i really want to understand how to solve it using ed. I have one solution using g/re/s/re//txt/ , but I want to understand how or if i can solve it using the ed (.)a command. A script i have parse several files and append text after a specific text is matched. If one file do not have this text, i get a no match and the script terminates. How can I avoid this behavior keeping the original coding style for ed and append text. I have tried tried but still cannot get it correct using (.)a. Is it even possible to do it that way using the (.)a command? Thanks in advance Thomas code example that give a "no match". Fairly easy to read and understand example 1: --- for RFILE in $RLIST; do ed - RFILE <<- EOF H /\[matching_text_1\]/a This is the appended textline(s) for text1 . /\[matching_text_2\]/a This is the appended textline(s) for text2 . w q EOF done Another example that solve the above problem. But this example become very easy unreadable if the appended text is long and/or includes linebreaks. Example 2: -- for RFILE in $RLIST; do ed - $RFILE << EOF g/text1/s//text1\\ appended_text1/g g/text2/s//text2\\ appended_text2/g w EOF done ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

A 128 bit encryption scheme may or may not be easily broken depending on which one it is. (Pick a good!)

Use the pvdisplay command and you'll see. # pvdisplay --- Physical volume --- PV Name /dev/sdb2 VG Name VolGroup00 PV Size 148.95 GB / not usable 11.37 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 4766 Free PE 0 Allocated PE 4766 PV UUID eeqb0A-6EJV-VE3Q-paLi-kTXv-S46k-0xaeTy Sit back a moment and think about it. You defined a PV on a specific device. That device is no longer available. LVM has to track the assignment, allocation and use of PVs. It must have a record of it somewhere. # ls -l /etc/lvm total 44 drwx-- 2 root root 4096 May 25 00:41 archive drwx-- 2 root root 4096 May 25 00:41 backup drwx-- 2 root root 4096 Aug 30 08:38 cache -rw-r--r-- 1 root root 15911 May 25 00:41 lvm.conf Use the man command to read up on more stuff, like "man lvm.conf" and "man lvm".

Normally you give a persistent device instead of a transient path. You didn't do that. Generally speaking, LVM is designed to use fixed devices - those that always come up on the same address. Neither iscsi nor UHB devices do this reliably. However, on a reboot, there is a liklihood that they will be the same devices. I've not tried to configure it on transient devices. There may be a way, but I've not looked into it. If you make them their own VG, rather than adding the PV to another VG, you can use the export and import LVM commands
[CentOS] LVM and hotswap (USB/iSCSI) devices?
Hi list, I'm having one of those 'I'm stupid' -problems with LVM on CentOS 5.2. I've been working with traditional partitions until now, but I've finally been sold on the theoretical benefits of using LVM, but for now I only have a huge pile of broken filesystems to show for my efforts. My scenario; I attach a disk, either over USB or iSCSI. I create a PV on this device, create a VG using the device, and slice off a tiny LV for tests.
