  • DNS "recursion not available" using a Cisco AnyConnect VPN connection

    - by codeape
    Does anyone have experience with configuring Cisco AnyConnect VPN? We have a problem with client DNS name resolution when connected over VPN. To me, it looks as if the Cisco AnyConnect VPN client intercepts DNS queries from the clients. Can someone confirm that the AnyConnect VPN client in fact does this (intercepts DNS traffic)? Where is this configured on the VPN server? EDIT: Here's how the routing table changes when I connect to the VPN: [~] $ diff -u /tmp/route_normal /tmp/route_vpn --- /tmp/route_normal 2010-01-20 19:23:47.000000000 +0100 +++ /tmp/route_vpn 2010-01-20 19:24:46.000000000 +0100 @@ -1,6 +1,10 @@ Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface +xxx.xxx.xx.xx.i 10.0.0.1 255.255.255.255 UGH 0 0 0 ath0 172.16.53.0 * 255.255.255.0 U 0 0 0 vmnet1 10.0.0.0 * 255.255.255.0 U 0 0 0 ath0 +172.17.20.0 * 255.255.255.0 U 0 0 0 cscotun 0 +192.168.111.0 172.17.20.212 255.255.255.0 UG 0 0 0 cscotun 0 172.16.140.0 * 255.255.255.0 U 0 0 0 vmnet8 +172.16.0.0 172.17.20.212 255.255.0.0 UG 0 0 0 cscotun 0 default 10.0.0.1 0.0.0.0 UG 0 0 0 ath0 EDIT 2: The IT guy has done "something" on the VPN endpoint.

  • Windows 7 Dell laptop Forgotten password

    - by jtmk
    Hi, A friend has managed to set up their new Windows 7 Home Premium Dell Inspiron and forgot the password they have used. I have tried the following password reset software to no avail: UBCD OHPCrack Offline NT Password & Registry Editor *Trinity Kon Boot I have also tried to do a system restore but this asks for the password. The user does not have any data they need to save. Is there anyway I can get access to the restore partition using Linux to create a recovery disk or do I have to purchase a recovery disk from Dell? Any help is greatly appreciated.

  • tcpdump filter that excludes private ip traffic

    - by Kyle Brandt
    For a generic filter to exclude all traffic in my dump that is between private IP address, I came up with the following: sudo tcpdump -n ' (not ( (src net 172.16.0.0/20 or src net 10.0.0.0/8 or src net 192.168.0.0/16) and (dst net 172.16.0.0/20 or dst net 10.0.0.0/8 or dst net 192.168.0.0/16) ) ) and (not ( (dst net 172.16.0.0/20 or dst net 10.0.0.0/8 or dst net 192.168.0.0/16) and (src net 172.16.0.0/20 or src net 10.0.0.0/8 or src net 192.168.0.0/16) ) )' -w test2.dump Seems pretty excessive, but it also seems to work, is this filter a lot longer than it needs to be and there is better way to express this logic, or is there anything wrong with the filter?

  • How to set up RAID 1 on Dell PERC S300 With Existing OS Install

    - by Daniel Dugger
    We have a server that is being used in production, but it was not originally meant to. The main thing I want to add to it is a Dell PERC S300 RAID Card to have the main hard drive (Windows Server 2008 R2) mirrored on another hard drive. I can not initialize the disk and wipe the the OS to create the array and then re-install. Is there a way to create the array with a current hard drive, without affecting it, and just mirroring the drive? If that card is not an option, is there a card that would allow that? The server is a Dell PowerEdge T110 II.

  • Monitoring HP and Dell hardware in Gentoo.

    - by ewwhite
    I'm working in an environment that features a large number of Gentoo servers running on HP ProLiant and Dell PowerEdge equipment. While I've moved some of these systems to RedHat or CentOS for consistency, I'm still left with a good number of systems that will remain Gentoo. One of the issues I see with the Gentoo arrangement is lack of vendor-supported hardware monitoring. There doesn't seem to be an equivalent to the HP ProLiant Support Pack or Dell's agents for Gentoo. Is this simply something that you give up when using this distribution? How do you monitor hardware health and the like with Gentoo systems?

  • Virtual machines interconnection inside Proxmox 2.1 Cluster

    - by Anton
    We have 3 physical servers (each with 1 NIC) in different datacentres, all of them are interconnected by openvpn bridged private network (10.x.x.x). Inside this network we have fully functional 3 nodes Proxmox 2.1 cluster. So, actually question is: Is there any "proper" way to make "global" local network (172.16.x.x) for all VMs inside cluster, so even if we move VM from one node to other we could reach it by static IP regardless of it's physical location? BTW, we can't add dedicated NIC to each server. Thanks in advance. EDIT: I have tried to make a separate openvpn bridge for 172.16.x.x, now I have at each server two interfaces: SRV1: openvpnbr1 - 172.16.13.1 vmbr0 - 172.16.1.1 SRV2: openvpnbr1 - 172.16.13.2 vmbr0 - 172.16.2.1 But now there is no connection between those ifaces: SRV1: ping 172.16.13.2 From 172.16.1.1 icmp_seq=2 Destination Host Unreachable SRV2: ping 172.16.13.1 From 172.16.2.1 icmp_seq=2 Destination Host Unreachable If I shut down vmbr0 interfaces, so there is connection between servers over openvpn, but vmbr0 is used by Proxmox... Where I am wrong?

  • postfix takes 60-90ms to queue email -- normal?

    - by Jeff Atwood
    We're seeing some (maybe?) strange delays when submitting individual emails to our local Postfix server. To help diagnose the issue, I wrote a little test program which sends 5 emails: get smtp 1ms ( 1 ms) email 0 677ms (676 ms) email 1 802ms (125 ms) email 2 890ms ( 88 ms) email 3 973ms ( 83 ms) email 4 1088ms (115 ms) Discounting the handshaking in the first email, that's about 90ms per email. These timings have also been corroborated with another test app written by someone else using a different codepath, so it appears to be server related. I turned on detailed logging and I can see that the delay is between the end of message \r\n\r\n and the receive: [16:31:29.95] [SEND] \r\n.\r\n [16:31:30.05] [RECV] 250 2.0.0 Ok: queued as B128E1E063\r\n [16:31:30.08] [SEND] \r\n.\r\n [16:31:30.17] [RECV] 250 2.0.0 Ok: queued as 4A7DE1E06E\r\n [16:31:30.19] [SEND] \r\n.\r\n [16:31:30.27] [RECV] 250 2.0.0 Ok: queued as 68ACC1E072\r\n [16:31:30.28] [SEND] \r\n.\r\n [16:31:30.34] [RECV] 250 2.0.0 Ok: queued as 7EFFE1E079\r\n [16:31:30.39] [SEND] \r\n.\r\n [16:31:30.45] [RECV] 250 2.0.0 Ok: queued as 9793C1E07A\r\n The time intervals tell the story (discounting the handshaking required for the initial email) -- each email is waiting about 60-90 milliseconds for postfix to queue! This seems .. excessive .. to me. Is it "normal" for postfix to take 60-90 ms for every email you send it? Or do I just have unreasonable expectations? I would expect the local postfix server to queue the email in about 20ms, tops!

  • A single AD user can't log into a single Mac bound to the domain (DirectoryServices error). How can I resolve this?

    - by Ben Wyatt
    On our campus, we have about 60 Macs joined to our Active Directory domain. Most users have no problems logging into Macs, as long as their accounts are configured correctly. However, we have one particular user who is unable to log in to just some of the Macs. He has no problem with most of them, but there is one group of them (all built from the same image) that he can't log in to. The machine in question is running OS X 10.6.2. The relevant entries from secure.log are below, with the hostname and username redacted. Aug 16 10:32:43 hostname SecurityAgent[4411]: Could not get the user record for username from DirectoryServices.

  • Dell Multi-Monitor Hub: true DisplayPort splitting?

    - by thepurplepixel
    In my search for a new display, I came across the Dell Multi-Monitor Hub MMH11, which seemed to be an alternative to my search for daisy-chainable DisplayPort displays. However, before I cave and spend $179 on this device, I am wondering if this will be similar to other splitting devices where it appears to the computer as one big monitor and the device does the splitting (which I don't want). Or, does this use the packet-based nature of DisplayPort to present two/three separate displays to the computer? Also, would this device work on my MacBook Pro? (I know the Dell site says it's for Windows, but it also says that no driver installation is required. I'd assume since the MBP supports DP 1.2 it would work, but it's better to ask). Thanks!

  • PCs on domain can not resolve external IP addresses using the DC's DNS Server

    - by Ben
    I currently have a domain controller which handles all DHCP and DNS. The DHCP works just fine and the domain controller itself can use the internet with no issues. However, PCs that are part of the domain are not able to use external websites, only internal. Does anyone have any way I can solve this issue?

  • NTP daemon or ntpdate doesn't synchronize

    - by user2862333
    I'm having some problems with synchronization with an NTP server. 1) The NTP daemon doesn't sync the system clock at all, even though it's running (confirmed with /etc/init.d/ntp status). Forcing to sync with ntpd -q or ntpd -gq does not work either. 2) Stopping the NTP daemon and syncing manually with ntpdate does give me the following output: ~# ntpdate -d 0.debian.pool.ntp.org 6 Nov 16:48:53 ntpdate[4417]: ntpdate [email protected] Sat May 12 09:07:19 UTC 2012 (1) transmit(79.132.237.5) receive(79.132.237.5) transmit(85.234.197.2) receive(85.234.197.2) transmit(194.50.97.34) receive(194.50.97.34) transmit(79.132.237.1) receive(79.132.237.1) transmit(79.132.237.5) receive(79.132.237.5) transmit(85.234.197.2) receive(85.234.197.2) transmit(194.50.97.34) receive(194.50.97.34) transmit(79.132.237.1) receive(79.132.237.1) transmit(79.132.237.5) receive(79.132.237.5) transmit(85.234.197.2) receive(85.234.197.2) transmit(194.50.97.34) receive(194.50.97.34) transmit(79.132.237.1) receive(79.132.237.1) transmit(79.132.237.5) receive(79.132.237.5) transmit(85.234.197.2) receive(85.234.197.2) transmit(194.50.97.34) receive(194.50.97.34) transmit(79.132.237.1) receive(79.132.237.1) server 79.132.237.5, port 123 stratum 2, precision -20, leap 00, trust 000 refid [79.132.237.5], delay 0.05141, dispersion 0.00145 transmitted 4, in filter 4 reference time: d624e3b1.f490b90d Wed, Nov 6 2013 16:50:09.955 originate timestamp: d624e457.eaaf787c Wed, Nov 6 2013 16:52:55.916 transmit timestamp: d624e36c.4a7036fd Wed, Nov 6 2013 16:49:00.290 filter delay: 0.08537 0.05141 0.05151 0.06346 0.00000 0.00000 0.00000 0.00000 filter offset: 235.6038 235.6087 235.6095 235.6068 0.000000 0.000000 0.000000 0.000000 delay 0.05141, dispersion 0.00145 offset 235.608782 server 85.234.197.2, port 123 stratum 2, precision -20, leap 00, trust 000 refid [85.234.197.2], delay 0.05151, dispersion 0.00336 transmitted 4, in filter 4 reference time: d624e3e7.dc6cd02b Wed, Nov 6 2013 16:51:03.861 originate timestamp: d624e458.1c91031f Wed, Nov 6 2013 16:52:56.111 transmit timestamp: d624e36c.7da1d882 Wed, Nov 6 2013 16:49:00.490 filter delay: 0.05765 0.07750 0.06013 0.05151 0.00000 0.00000 0.00000 0.00000 filter offset: 235.6048 235.6014 235.6035 235.6078 0.000000 0.000000 0.000000 0.000000 delay 0.05151, dispersion 0.00336 offset 235.607826 server 194.50.97.34, port 123 stratum 3, precision -23, leap 00, trust 000 refid [194.50.97.34], delay 0.03021, dispersion 0.00090 transmitted 4, in filter 4 reference time: d624e38d.2bce952c Wed, Nov 6 2013 16:49:33.171 originate timestamp: d624e458.4dbbc114 Wed, Nov 6 2013 16:52:56.303 transmit timestamp: d624e36c.b0d38834 Wed, Nov 6 2013 16:49:00.690 filter delay: 0.03030 0.03636 0.03091 0.03021 0.00000 0.00000 0.00000 0.00000 filter offset: 235.6095 235.6085 235.6098 235.6105 0.000000 0.000000 0.000000 0.000000 delay 0.03021, dispersion 0.00090 offset 235.610589 server 79.132.237.1, port 123 stratum 3, precision -20, leap 00, trust 000 refid [79.132.237.1], delay 0.05113, dispersion 0.00305 transmitted 4, in filter 4 reference time: d624dfcb.6acea332 Wed, Nov 6 2013 16:33:31.417 originate timestamp: d624e458.838672ad Wed, Nov 6 2013 16:52:56.513 transmit timestamp: d624e36c.e405181c Wed, Nov 6 2013 16:49:00.890 filter delay: 0.06345 0.05113 0.05681 0.05656 0.00000 0.00000 0.00000 0.00000 filter offset: 235.6087 235.6038 235.6010 235.6074 0.000000 0.000000 0.000000 0.000000 delay 0.05113, dispersion 0.00305 offset 235.603888 6 Nov 16:49:00 ntpdate[4417]: step time server 79.132.237.5 offset 235.608782 sec Clearly, ntpdate can reach the NTP server(s), but after checking the clock, it hasn't changed and is still displaying the wrong time.

  • How to slave a 3.5" 500gb sata external hdd(Western Digital) to my dell Inspiron laptop

    - by AJ HDD
    i have a 3.5" western digital my book 500gb external hdd....i gave it to a friend of mine and he broke the usb port in it...i went to a nearby comp repair shop and had him solder the thing...it didnt detect when i plugged it in my dell inspiron laptop........i recently saw about the 3.5" sata to usb enclosure, so i went to check it....strangely when its placed in the enclosure, its not detecting in windows...also when it was put as secondary(im guessing slave) to the shop fellow's desktop it shows up in the bios and starting, but then again doesnt show in windows 7, and the guy told me i need to data recovery to get teh data back p.s.the wd hdd doesnt have os, just data, soo my question is: can i slave the drive to my dell laptop and try to recover the data....if so how? please i would really appreciate it...thanks in advance

  • Remove CR LF for all lines that are not followed by a specific number

    - by Kjeldsen
    I have 14000+ lines of a database, that I want to edit with Notepad++. All these lines should start with 1000 and I therefore want to delete CR LF at the end of those lines that are not followed by 1000. Eg. 1000 16 04000 CRLF sdfsdf 15 sdf de 05550 CRLF 1000 16 04000 CRLF 1000 16 04000 CRLF 5. sdkfd dksds 16 0555 CRLF 10/10/14 sdfsdf CRLF should after find and replace look like 1000 16 04000 sdfsdf 15 sdf de 05550 CRLF 1000 16 04000 CRLF 1000 16 04000 5. sdkfd dksds 16 0555 10 sdfsdf CRLF I have tried with find what: \r\n([^1000]) Replace with _\1 However, this doesn't seem to remove lines starting with a number (like 5. or 10/10/14). Is it possible to make just one RegEx to find and remove all line breaks that isn't followed by 1000? "_" indicating a "space"

  • Windows 2008 R2 DHCP Overlapping Scopes

    - by Buska
    We are trying to troubleshoot a scope overlap problem. We have multiple device types we wish to give all different ranges of a 16 bit subnet. IE. X device we wish to give 192.168.2.1-192.168.2.254/16, Y devices we wish to give 192.168.3.1-192.168.3.254/16. We are trying to accomplish this by creating different scopes and using the 60 class identifier. The problem is DHCP won't allow us to give these scopes with 16 bit masks because of the potential overlap. We aren't overlapping the address pool so why does DHCP care and can we work around this? If this isn't possible, how can i assign specific ranges by device type without creating multiple scopes? Any thoughts would be helpful. UPDATE: Entire Scope is 192.168.0.0/16 Gateway is 192.168.1.1/16 Device Hardware A - 192.168.20.1-192.168.20.254/16 Device Hardware B - 192.168.26.1-192.168.26.254/16 Device Hardware C - 192.168.85.1-192.168.85.254/16 We tried to setup multiple scopes for each device type (A,B,C) but couldn't specify a 16 bit mask as Scope A could technically overlap Scope B even thought our start and end addresses don't. I hope this makes more sense. Thanks for your thoughts.

  • iptables (DNAT)

    - by user1126425
    I have a host that acts as a gateway for other hosts. The configuration is such that eth0(192.168.1.3) is connected to internet via a router and eth1(172.16.2.50) is connected to internal network via switch. Given that, this host is also running a service that is bound to eth1 and serves the internal network. I want to extend this service to the outside world as well and was trying to manipulate iptables so that any request that comes to this host via eth0 and is directed to 192.168.1.3:80 is send to 172.16.2.50 and internet users can also make use of the service. Here are my iptable rules for setting up the host as gateway (and these work fine): sudo iptables -t nat -A POSTROUTING -s 172.16.2.0/16 -o eth0 -j MASQUERADE sudo iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth1 -j MASQUERADE sudo iptables -A FORWARD -s 172.16.2.0/16 -o eth0 -j ACCEPT sudo iptables -A FORWARD -d 172.16.2.0/16 -m state --state ESTABLISHED,RELATED -i eth0 -j ACCEPT And these are the rules that I am trying to add to the iptables to achieve my ends: sudo iptables -A INPUT -d 192.168.1.3 -p tcp -dport 80 -i eth0 -j ACCEPT sudo iptables -t nat -A PREROUTING -d 192.168.1.3 -p tcp -dport 80 -j DNAT --to-destination 172.16.2.50:80 sudo iptables -t nat -A PREROUTING -s 172.16.2.50 -p tcp -sport 80 -j SNAT --to-source 192.168.1.3:80 sudo iptables -A FORWARD -d 192.168.1.3 -p tcp -dport 80 -m state --state ESTABLISHED,RELATED -j ACCEPT When I do so, I get error like : "multiple -d flags not allowed" ... Can someone tell me how to resolve this error... and do the entries that I want to add will serve my purpose ? Thanks!

  • Optimizing Solaris 11 SHA-1 on Intel Processors

    - by danx
    SHA-1 is a "hash" or "digest" operation that produces a 160 bit (20 byte) checksum value on arbitrary data, such as a file. It is intended to uniquely identify text and to verify it hasn't been modified. Max Locktyukhin and others at Intel have improved the performance of the SHA-1 digest algorithm using multiple techniques. This code has been incorporated into Solaris 11 and is available in the Solaris Crypto Framework via the libmd(3LIB), the industry-standard libpkcs11(3LIB) library, and Solaris kernel module sha1. The optimized code is used automatically on systems with a x86 CPU supporting SSSE3 (Intel Supplemental SSSE3). Intel microprocessor architectures that support SSSE3 include Nehalem, Westmere, Sandy Bridge microprocessor families. Further optimizations are available for microprocessors that support AVX (such as Sandy Bridge). Although SHA-1 is considered obsolete because of weaknesses found in the SHA-1 algorithm—NIST recommends using at least SHA-256, SHA-1 is still widely used and will be with us for awhile more. Collisions (the same SHA-1 result for two different inputs) can be found with moderate effort. SHA-1 is used heavily though in SSL/TLS, for example. And SHA-1 is stronger than the older MD5 digest algorithm, another digest option defined in SSL/TLS. Optimizations Review SHA-1 operates by reading an arbitrary amount of data. The data is read in 512 bit (64 byte) blocks (the last block is padded in a specific way to ensure it's a full 64 bytes). Each 64 byte block has 80 "rounds" of calculations (consisting of a mixture of "ROTATE-LEFT", "AND", and "XOR") applied to the block. Each round produces a 32-bit intermediate result, called W[i]. Here's what each round operates: The first 16 rounds, rounds 0 to 15, read the 512 bit block 32 bits at-a-time. These 32 bits is used as input to the round. The remaining rounds, rounds 16 to 79, use the results from the previous rounds as input. Specifically for round i it XORs the results of rounds i-3, i-8, i-14, and i-16 and rotates the result left 1 bit. The remaining calculations for the round is a series of AND, XOR, and ROTATE-LEFT operators on the 32-bit input and some constants. The 32-bit result is saved as W[i] for round i. The 32-bit result of the final round, W[79], is the SHA-1 checksum. Optimization: Vectorization The first 16 rounds can be vectorized (computed in parallel) because they don't depend on the output of a previous round. As for the remaining rounds, because of step 2 above, computing round i depends on the results of round i-3, W[i-3], one can vectorize 3 rounds at-a-time. Max Locktyukhin found through simple factoring, explained in detail in his article referenced below, that the dependencies of round i on the results of rounds i-3, i-8, i-14, and i-16 can be replaced instead with dependencies on the results of rounds i-6, i-16, i-28, and i-32. That is, instead of initializing intermediate result W[i] with: W[i] = (W[i-3] XOR W[i-8] XOR W[i-14] XOR W[i-16]) ROTATE-LEFT 1 Initialize W[i] as follows: W[i] = (W[i-6] XOR W[i-16] XOR W[i-28] XOR W[i-32]) ROTATE-LEFT 2 That means that 6 rounds could be vectorized at once, with no additional calculations, instead of just 3! This optimization is independent of Intel or any other microprocessor architecture, although the microprocessor has to support vectorization to use it, and exploits one of the weaknesses of SHA-1. Optimization: SSSE3 Intel SSSE3 makes use of 16 %xmm registers, each 128 bits wide. The 4 32-bit inputs to a round, W[i-6], W[i-16], W[i-28], W[i-32], all fit in one %xmm register. The following code snippet, from Max Locktyukhin's article, converted to ATT assembly syntax, computes 4 rounds in parallel with just a dozen or so SSSE3 instructions: movdqa W_minus_04, W_TMP pxor W_minus_28, W // W equals W[i-32:i-29] before XOR // W = W[i-32:i-29] ^ W[i-28:i-25] palignr $8, W_minus_08, W_TMP // W_TMP = W[i-6:i-3], combined from // W[i-4:i-1] and W[i-8:i-5] vectors pxor W_minus_16, W // W = (W[i-32:i-29] ^ W[i-28:i-25]) ^ W[i-16:i-13] pxor W_TMP, W // W = (W[i-32:i-29] ^ W[i-28:i-25] ^ W[i-16:i-13]) ^ W[i-6:i-3]) movdqa W, W_TMP // 4 dwords in W are rotated left by 2 psrld $30, W // rotate left by 2 W = (W >> 30) | (W << 2) pslld $2, W_TMP por W, W_TMP movdqa W_TMP, W // four new W values W[i:i+3] are now calculated paddd (K_XMM), W_TMP // adding 4 current round's values of K movdqa W_TMP, (WK(i)) // storing for downstream GPR instructions to read A window of the 32 previous results, W[i-1] to W[i-32] is saved in memory on the stack. This is best illustrated with a chart. Without vectorization, computing the rounds is like this (each "R" represents 1 round of SHA-1 computation): RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR With vectorization, 4 rounds can be computed in parallel: RRRRRRRRRRRRRRRRRRRR RRRRRRRRRRRRRRRRRRRR RRRRRRRRRRRRRRRRRRRR RRRRRRRRRRRRRRRRRRRR Optimization: AVX The new "Sandy Bridge" microprocessor architecture, which supports AVX, allows another interesting optimization. SSSE3 instructions have two operands, a input and an output. AVX allows three operands, two inputs and an output. In many cases two SSSE3 instructions can be combined into one AVX instruction. The difference is best illustrated with an example. Consider these two instructions from the snippet above: pxor W_minus_16, W // W = (W[i-32:i-29] ^ W[i-28:i-25]) ^ W[i-16:i-13] pxor W_TMP, W // W = (W[i-32:i-29] ^ W[i-28:i-25] ^ W[i-16:i-13]) ^ W[i-6:i-3]) With AVX they can be combined in one instruction: vpxor W_minus_16, W, W_TMP // W = (W[i-32:i-29] ^ W[i-28:i-25] ^ W[i-16:i-13]) ^ W[i-6:i-3]) This optimization is also in Solaris, although Sandy Bridge-based systems aren't widely available yet. As an exercise for the reader, AVX also has 256-bit media registers, %ymm0 - %ymm15 (a superset of 128-bit %xmm0 - %xmm15). Can %ymm registers be used to parallelize the code even more? Optimization: Solaris-specific In addition to using the Intel code described above, I performed other minor optimizations to the Solaris SHA-1 code: Increased the digest(1) and mac(1) command's buffer size from 4K to 64K, as previously done for decrypt(1) and encrypt(1). This size is well suited for ZFS file systems, but helps for other file systems as well. Optimized encode functions, which byte swap the input and output data, to copy/byte-swap 4 or 8 bytes at-a-time instead of 1 byte-at-a-time. Enhanced the Solaris mdb(1) and kmdb(1) debuggers to display all 16 %xmm and %ymm registers (mdb "$x" command). Previously they only displayed the first 8 that are available in 32-bit mode. Can't optimize if you can't debug :-). Changed the SHA-1 code to allow processing in "chunks" greater than 2 Gigabytes (64-bits) Performance I measured performance on a Sun Ultra 27 (which has a Nehalem-class Xeon 5500 Intel W3570 microprocessor @3.2GHz). Turbo mode is disabled for consistent performance measurement. Graphs are better than words and numbers, so here they are: The first graph shows the Solaris digest(1) command before and after the optimizations discussed here, contained in libmd(3LIB). I ran the digest command on a half GByte file in swapfs (/tmp) and execution time decreased from 1.35 seconds to 0.98 seconds. The second graph shows the the results of an internal microbenchmark that uses the Solaris libpkcs11(3LIB) library. The operations are on a 128 byte buffer with 10,000 iterations. The results show operations increased from 320,000 to 416,000 operations per second. Finally the third graph shows the results of an internal kernel microbenchmark that uses the Solaris /kernel/crypto/amd64/sha1 module. The operations are on a 64Kbyte buffer with 100 iterations. third graph shows the results of an internal kernel microbenchmark that uses the Solaris /kernel/crypto/amd64/sha1 module. The operations are on a 64Kbyte buffer with 100 iterations. The results show for 1 kernel thread, operations increased from 410 to 600 MBytes/second. For 8 kernel threads, operations increase from 1540 to 1940 MBytes/second. Availability This code is in Solaris 11 FCS. It is available in the 64-bit libmd(3LIB) library for 64-bit programs and is in the Solaris kernel. You must be running hardware that supports Intel's SSSE3 instructions (for example, Intel Nehalem, Westmere, or Sandy Bridge microprocessor architectures). The easiest way to determine if SSSE3 is available is with the isainfo(1) command. For example, nehalem $ isainfo -v $ isainfo -v 64-bit amd64 applications sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu 32-bit i386 applications sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov sep cx8 tsc fpu If the output also shows "avx", the Solaris executes the even-more optimized 3-operand AVX instructions for SHA-1 mentioned above: sandybridge $ isainfo -v 64-bit amd64 applications avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu 32-bit i386 applications avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov sep cx8 tsc fpu No special configuration or setup is needed to take advantage of this code. Solaris libraries and kernel automatically determine if it's running on SSSE3 or AVX-capable machines and execute the correctly-tuned code for that microprocessor. Summary The Solaris 11 Crypto Framework, via the sha1 kernel module and libmd(3LIB) and libpkcs11(3LIB) libraries, incorporated a useful SHA-1 optimization from Intel for SSSE3-capable microprocessors.
