Apache Mod Rewrite

bubaphex — Wed, 16 May 2012 05:00:57 GMT

Hi guys,

im having issues understating how [P] works in mod rewrite

i have this:

RewriteRule ^/mysubdir(.*) http://myotherwebsite.com/subdirectory$1 [P]

the rewrite doesnt seam to work, mod rewrite is install and is working find. Do i need to have something else installed? acording to php.ini mod_proxy has loaded.

im doing this in my .htaccess folder, should i be doing this in vhosts?

Thanks

Webmin from afar

glennzo — Tue, 15 May 2012 12:19:52 GMT

Would anyone know if it is possible to access WebMin on my server at home from somewhere other than the local network? I think I'd like to access it from work.

I've been browsing the web, the WebMin wiki, etc, for information but I don't really know exactly what I should be looking for.

WebMin is installed and completely functional on the server.

Maybe all I really need to do is enable port forwarding for the webmin port. Sounds dangerous.

F15 yum update php-, httpd- and neither will start...

xtian — Sat, 12 May 2012 20:17:16 GMT

Neither php or httpd will start after a yum update. I yum updated the following:
php-*, 44M
mysql-*, 44M
httpd-*, 1.9M
glibc, ...
This LAMP server was working fine since I upgraded to F15 last October. I'm having trouble with a PHP framework and thought an update would be useful. :doh:

# php

Code:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mapi.so' - /usr/lib/php/modules/mapi.so:      undefined symbol: _ZN9ECUnknown10IsParentOfEPS_ in Unknown on line 0

libgcc_s.so.1 must be installed for pthread_cancel to work

Aborted

Various solutions called for,
* updating glibc-i686-2.14.1
* add library location of libgcc_s to $LD_LIBRARY_PATH

Apache won't start either.

Code:

# stemctl status httpd.service

httpd.service - LSB: start and stop Apache HTTP Server

   Loaded: loaded (/etc/rc.d/init.d/httpd)

!  Active: active (exited) since Sat, 12 May 2012 13:36:58 -0400; 34min ago

   Process: 1164 ExecStart=/etc/rc.d/init.d/httpd start (code=exited, status=0/SUCCESS)

   Main PID: 1445 (code=killed, signal=ABRT)

   CGroup: name=systemd:/system/httpd.service

Searching through the /var/log/messages, and /var/log/httpd found a few items, one,

Code:

!! May 12 12:05:23 10 systemd[1]: Unit httpd.service entered failed state.

I googled to find the following recommendations:
* add ChrootDir / to httpd.conf
and this also points to the libgcc_s issue which php is experiencing.

any other ideas?

Samba wont allow me to connect to shares on second partition

kameelperdza — Fri, 11 May 2012 16:25:39 GMT

Hi there

I have installed Fedora 16 lxde 64bit spin.

I followed the steps to setup samba using this link

http://www.howtoforge.com/fedora-12-...tdbsam-backend

I have not made big changes to the smb.conf file.

I have only added my shares and also add this......

Code:

# This option controls how unsuccessful authentication attempts are mapped

# to anonymous connections

   map to guest = bad user

all of my shares is located on /home/shares/

During setup i have chosen to create seperate partition for /home/shares

The problem that i have is that when i try to connect from windows then i wil get access denied error, telling me to check permissions etc.

But if i create a share before the partion (FOR EXAMPLE /home/new INSTEAD OF /home/shares/new) then i am able to connect without problem.

I think it has something to do with the shares folder having its own partition.

Any ideas? :confused:

DNS Setup Help Needed for LAN

Aurora007 — Sat, 05 May 2012 20:28:28 GMT

I'm trying to set up a DNS for our internal network. I have been unable to find good information on how to do this on a network that does not have internet connection. I do have bind installed on our Fedora 14 server but I have not yet attempted to configure bind. We have about 15 various window machines on our network.

I am currently using hosts files to resolve names but I'm trying to make it easier when we configure new machines on our system.

One other question: On server network configuration what do i use for gateway address since we do not have an internet connection.

Any help would be greatly appreciated, I have been searching for quite some time and am starting to get a little frustrated.

Apache Proxy to site and have it know IP

IHeart SymLinks — Thu, 03 May 2012 16:30:06 GMT

I have a VirtualServer in Apache with the following rewrite rule

RewriteRule (.*) http://127.0.0.1:8399$1 [P,L]

The site that Apache is proxying to shows all requests coming from localhost. I understand why this is happening, but I would like it to show the real IP of visitors, is this possible? Can Apache send the real IP?

Virtual Servers

stevea — Thu, 03 May 2012 16:07:04 GMT

My application s a home SOHO server.

So for years I've gone through the cycles of keeping a mail server (postfix, dovecot, fetchmail, spamassassin). First on Fedora - but that was a bad decision. Fedora changes often and working through all the config changes while still maintaining reliable email service was not pleasant. Then I kept a sysem thtat peformed email service on Centos - but this means a box dedicated to email and a few other basic services (printer & file share). and the fact that RHEL/Centos/ScentificLinux(SL) packages were too far behind meant I used the system for little else - a waste of resource.

So recently I create a KVM virtualization of SL6.2 and have started using it for mail service. Some features:

/ The network interface is bridged to the host - so performance is great.
/ The SL minimal install + packages ended up around 1.1 GB + the maildir space + swap.
/ I was able to pare down the virtualization to use only 1 core and 680MB of RAM, and am getting this :

Code:

[root@mail /]# free

             total       used       free     shared    buffers     cached

Mem:        663476     560192     103284          0      50932     203452

-/+ buffers/cache:     305808     357668

Swap:      4194296       2876    4191420

It seems to always use a little swap after a day+ of uptime.
/ On the host system the guest process looks like ...

Code:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+ COMMAND                                                                                                               

 1927 qemu      20   0 1318m 684m 4092 S  6.3  8.9 159:35.37 qemu-kvm

Where the resident RAM ~680M is expected and the 1.3GVB virt seems a bit large - however it's still smaller than firefox.
/ The libvirtd/virt-manager feature to start the virtualization at boot time works perfectly.
/ The KVM image is reasonably portable to other RH family OSes and to Fedora across updates.

Issues: And I'd appreciate any comments on these.
/ Is there a way to cleanly shutdown the KVM virtualization ? (Is this happening already)?
/ I'd like to minimize the size and CPU usage of the guest with the goal to not perform a lot of 'manual' surgery and to keep up with the Scientific Linux yum updates.
// There are a few packages to remove and a little cruft to remove from root.
// I suppose I could choose a compressed file system - but' that costs CPU time which is more valuable.
/ There is a very complex trade-off between guest image-file -size, dram size and swap size and performance. I could give the guest enough DRAM to never swap (say 1GB) and then allow the host system to swap out it's pages as needed (but impacts host performance at times). I could give the guest a small DRAM (say 400mb OR 500mb) then allow the guest to swap to the virtual disk (less efficient virtual I/O BUT reduces DRAM usage).
/ For CPU usage it appears that the virtualization uses ~6% of one host cores constantly, even tho the guest loadavg is microscopic (0.01 - 0.02). I'd like to get that down.
/ I might have been better off w/ an i686 not x86_64 guest distro - unclear.

Not a Fedora problem, but even on SL6.2 it seems it's sort of difficult to make fetchmail,postfix,spamassassin,dovecot all play together nicely with selinux enforcing. After struggling through a relabeling session the broken bits were that spamassassin couldn't send output on the postfix socket, and I hadn't fully debugged fetchmail daemon yet. A dovecot plugin to awaken fetchmail was having problems too.

[Fedora 15] Slow network after upgrade

Skiriki — Thu, 03 May 2012 00:26:09 GMT

Hi; I run two servers at home, and I recently ran into a trickier sort of problem.

We'll call them ns1 and ns2. ns1 is the primary server where serious bizniz happens, and ns2 is a testbed for stuff.

Both servers are reasonably identical: both are AMD + Asus MB, with embedded Realtek chipset for ethernet, and with a second ethernet card (100% identical, bought at the same time etc).

Both servers have similar functions: they run bind, httpd, sendmail, mysql, php, several wikis, forums and such; ns1 also runs dovecot and squirrelmail. Both were assembled and installed by me.

On both servers, eth0 is the internal network's NIC, and it is trusted. eth1 is IP-masquerading, and not trusted; iptables pokes enough prerequisite holes to it, to let it work as web and mail server etc. Both servers have identical iptables setup. On both systems, eth1 routes traffic outside. On both systems, eth0 has a static IP (192.168.0.1 and .2, respectively), and eth1 receives its static IP address from my ISP (with MAC-based identification).

Both servers are connected to the same DSL box, and both servers are connected to the same switch in internal network, using same type of cable. Yay for standardization.

Originally, both servers ran Fedora 13.

I upgraded ns2 around January 2012 to Fedora 15, via DVD, using "upgrade" option, and everything went swimmingly, no problems. I have continued to update the server via yum, and everything is still just fine.

I upgraded ns1 on 1st of May, 2012, to Fedora 15, via DVD, using "upgrade" option, and performance is drastically different. Immediately after upgrading, I ran yum to retrieve update packets, and I thought that was that.

Well, no.

ns2 continues behaving splendidly.

ns1, on the other hand, slows down and then messes something between eth0 and eth1. This is detectable with a simple test: I try to download stuff when my desktop is using ns1 for routing; speed starts at 35 KB/s, then keeps dropping until it is at zero.

If I swap to ns2 for routing, and try to download again, I will get the 2 Mbit/s as I'm supposed to.

However, if I log in to ns1, and start a download off the command line (like, say, with wget), I will get 2Mbit/s again.

This stunted downloading includes downloads from the server itself, while in internal network: prior to update, it worked fast, and content was quick to load.

ethtool tells me that all NICs are running at full speed.

I have already tried to disable ipv6, up to the point of removing ip6tables from loadable services, but ns2 runs just fine with ip6tables lurking about. Both systems do not use ipv6 for any of their NICs.

I have added biosdevname=0 to kernel line in grub.conf, and it still makes no difference (and ns2 runs just fine without it).

I have tried to reinstall kernel and various other things, and none of them make a difference.

My kernel line looks like this:

kernel /vmlinuz-2.6.43.2-6.fc15.x86_64 root=UUID=9b7277da-bf2f-4ef1-be90-2f7226935c9a ro rd_MD_UUID=84894a3e:0e0dff17:4dc693b9:2565f0cc rd_MD_UUID=a4851993:0ba36d09:736988a9:b06084d4 rd_NO_LUKS rd_NO_LVM rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=fi-latin1 iommu=noaperture biosdevname=0

I do not spot any obvious problems in /var/log/messages, /var/log/boot.log or dmesg.

I am starting to reach my wits' end, and I can't figure it out.

Please help me. Or at least toss some ideas, so I can try to google and figure it out on my own; I'm out of ideas.

---------- Post added at 03:26 AM ---------- Previous post was at 01:00 AM ----------

Additional information and a tiny correction:

This is eth0:
Bridge: nVidia Corporation MCP61 Ethernet (rev a2)
Subsystem: ASUSTeK Computer Inc. Device 83a4
Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 43
Memory at dedf9000 (32-bit, non-prefetchable) [size=4K]
I/O ports at c480 [size=8]

Capabilities: [50] MSI: Enable+ Count=1/8 Maskable+ 64bit+
Capabilities: [6c] HyperTransport: MSI Mapping Enable- Fixed+
Kernel driver in use: forcedeth
Kernel modules: forcedeth

This is eth1:
Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)
Subsystem: Realtek Semiconductor Co., Ltd. RTL8169/8110 Family PCI Gigabit Ethernet NIC
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 18
I/O ports at d800 [size=256]
Memory at deeffc00 (32-bit, non-prefetchable) [size=256]
Expansion ROM at deec0000 [disabled] [size=128K]
Capabilities: [dc] Power Management version 2
Kernel driver in use: r8169
Kernel modules: r8169

Now, a quick google shows that some people have had problems with forcedeth drivers. Any idea if this would be it?

Would this get fixed by feeding Fedora 16 to it? Or should I try something else?

Apache SIGTERM issues

Makkura666 — Mon, 23 Apr 2012 11:12:16 GMT

Hey guys,

I've been searching for hours yesterday to solve this problem but no one seems to be giving a clear answer of what this could be.

So I've been installing the latest fedora fresh on my laptop I wish to use with apache. Then I followed some basic instructions on a youtube tutorial to set it up locally (which works). Then when I try to make my server public by entering my ip and fiddling around with my ports on my router it just doesn't work to get it public but the server is still running and after restarting the server for a couple times while adjusting the ip a few times it gives the "SIGTERM" notice in the log and shuts down every time. Putting all values to their default ones doesn't work either it won't start after giving a single SIGTERM.

When I reinstall apache it will work again (for a while tho) but then it shuts down again after lets say an hour or 2 of fiddling around. I already know a SIGTERM can be given by a provider or by the computer itself but I have no clue how I can make it stop shutting down like that. I've being trying allot of things like shutting down the SELinux security which didn't work either.

Any ideas anyone? :(

Logs show that this has been going on for a long time with hundreds of the same "panic" errors. I'd like to resolve this issue so that the e-mail gets sent as expected.

The error I highlighted above is the most recent and was the result of the command

PHP Code:


		
			
logwatch --mailto glennjohnson57@gmail.com

however, it is my belief that I should at least be getting root mail on the server if not one of my e-mail addresses.

PHP Code:


		
			
[root@server ~>$ mail

No mail for root

Most of the expected mail would be from rkhunter but logwatch mail would be nice too along with any other security related mail.

Does anyone have any thoughts on this?
