Net Hook driver

Hi;
I'm trying to port a Linux Kernel Module we wrote to Solaris 10.
The modules uses the Linux Netfilter Hooks to do packet manipulations before they get to the application.
Is there a similar way in Solaris 10 to filter/manipulate tcp/ip packets ?
I need something similar to the :
Pre-Routing
Local
Forward
Post-routing
Hooks that I get from the netfilter interface in the Linux Kernel
But anything similar that let me filter / change packet will be ok
Thanks

Hello,
<br><br>
the STREAMs between IP<->TCP (lately IP<->UDP) was removed in Sol10, you can add streams below IP (like IpFilter). New architecture (FireEngine) whitepaper is here . There was also xpert discussion. Some book, presentation, previous discuss or blogs 1 + 2 maybe usefull.

WARNING with latest kernel: at net/mac80211/driver-ops.

Hi. i'm running the latest kernel and having many kernel oops like the attached, any ideas? is this a problem already in upstream? should I open a bug report in archlinux? I'm thinking to switch to LTS.
TIA.

unload nvidia module and then load did.
rmmod nvidia && modprobe nvidia
Next time pay attention of pacman message:
In order to use the new nvidia module, exit Xserver and unload it manually.

It looks like missing the end of the command line 6, a semicolon.

Using the mkinitcpio net hook confuses netcfg

Hello everybody.
I am currently trying to build a headless Linux home server, and I decided to try out Arch.
The server has an encrypted root file system by means of having a plain-text /boot 1st partition and having the / file system on a 2nd LUKS partition.
For starters I used the mkinitcpio hooks "keymap keyboard encrypt", with the appropriate "cryptdevice=..." and "root=..." kernel parameters to make the server prompt me for the pass phrase in early user space, which works nicely.
As this thing is supposed to become a headless system I then tried to set it up in a way that enables me to open an SSH connection into the early user space and supply the pass phrase from there, using dropbear_initrd_encrypt. And it works! This is great stuff.
Unfortunately doing this broke the then-running server's network connection.
I have a static IP address netcfg profile that is loaded from systemd on server start-up (systemctl enable netcfg; the profile is set in the "NETWORKS=..." variable in "/etc/conf.d/netcfg").
The ethernet device is called "enp2s0".
This worked flawlessly until I started using the "net" mkinitcpio hook to get a network connection in early user space for the remote unlocking.
The net hook's corresponding kernel parameter looks like "ip=<ip>:::<netmask>:::none"
When I use this hook, the system boots up without having the "enp2s0" ethernet device, causing netcfg to bail out.
It does however gain the same network device as "eth0" instead, which is apparently how early user space calls it. This "eth0" ethernet device appears to retain the settings it has been set up with by the net hook.
Unfortunately the net hook does not supply things like a default gateway or DNS servers, so while the server technically is reachable from the local network, it cannot access the internet, which it definitely needs to be able to do.
After tracking this down I figured "Whatever. I can live with the ethernet device being called eth0."
So I made a second identical netcfg profile, exchanging "enp2s0" for "eth0", and set the server to load that one instead when booting.
That unfortunately did not work either, because netcfg is cautious and aborts when it is told to set up a network adapter that is already active in some way unknown to netcfg.
What also didn't help was specifying the "enp2s0" ethernet device name in the "ip=..." kernel parameter for the net hook, because indeed the early user space only knows the device as "eth0".
So for now I'm stumped. Anyone experienced this issue and managed to solve it?
A solution might be another "disablenet" mkinitcpio hook that deconfigures the network adapters configured by "net", so that the renaming from "eth0" to "enp2s0" during boot, which I assume fails on account of "eth0" being active, works again.
Thanks for any help,

Okay, I tried that.
I put both netcfg profiles into the "NETWORKS=..." variable in "/etc/conf.d/netcfg", and added this to both of them:
# Clear leftover state from mkinitcpio net hook
PRE_UP="ip link set <device> down || true"
where <device> is eth0 or enp2s0, respectively.
After a reboot with remote decryption the server's network was down completely. Looks like the "ip link set ... down" command worked all right, but the rest didn't go as planned.
Here's what systemctl says about that:

As before, device "enp2s0" is missing, but "eth0" doesn't come up either, even after being downed manually beforehand :-(
Strangely enough, if I do "netcfg -u static_eth0" after that, eth0 does come up. What?!
@falconindy: Applying a udev rule in early user space would require to make a custom initcpio hook, wouldn't it?
In that case I'd rather try to figure out what the "net" hook does and undo it, seeing that I have to write a custom hook anyway and that "eth0" doesn't come up no matter what.
Having an "enp2s0" ethernet device that doesn't come up either isn't going to do me much good ;-)
Thanks for the suggestions,

Net hook to bring up wlan

I have a arch system with encrypted root partition, that I want to be headless in the future. There is a AUR package to get dropbear support for the initrd, so I can unlock the root partition remotely. As far as I can tell does this package use the net hook from mkinitcpio to set up the network.
Unfortunately the system doesn't have wired access to the network, only wireless (wpa2 secured). Is it possible to have a wireless network that early in the boot process?

New 64-bit kernel likes my network too, so don't know about bug.

Mkinitcpio net hook broken?

I-net oranxo driver problem. cannot connect

Hi, im new to the j2ee programming communitty and i was trying to use the i-net type 4 driver to connect to an oracle database. The service name of the oracle database is orcl. i know that the host is the local host, and im pretty sure that the port number is 1521. i dont think i changed it. unfortunately i dont know how to change it. if you could tell me a way to change it once i have already installed it, i would appreciate it.
my code for this problem is
import java.sql.*;
public class testDB{
public static void main(String args[])
     new testDB();
testDB()
     try{
          Connection con = DriverManager.getConnection("jdbc:inetora:localhost:1521:orcl", "scott", "tiger" );
          new com.inet.ora.OraDriver();
          CallableStatement cstmt = con.prepareCall("{call procone(?,?,?)}");
          cstmt.setInt(1,6619211);
          cstmt.setString(2,"Java");
          cstmt.setInt(3,22);
          cstmt.execute();
          con.close();
          }catch(Exception x){
                    System.out.println("exception: "+x);
the error its giving me is the following
com.inet.ora.ORA3SQLException: [OraDriver] Connection Refused:Connect
Anyone know why theres a problem. im sorry i know its probably a dumb question but i cant figure this out.

re: Oracle database and listener:
Oracle does not do things in a simple way. I'll explain things using Oracle's terminology (which I didn't use earlier).
To Oracle, the collection of data-storage (files or devices) that actually has the data is the "database", without regard to any program code or running process.
To Oracle, the memory structures and process (or threads on some OSes) normally used to access a database is called an "instance". (In casual speech, most people call the "instance" the "database"; usually the distinction doesn't matter).
You can have a database without an instance (the program isn't running), an instance without a database (the database hasn't been created or you're using a special Oracle feature called ASM), or you can have multiple instances for one database (an Oracle RAC cluster).
You cannot connect directly to an Oracle instance via a TCP/IP connection (which is normally what a JDBC driver will use, although there are other ways). Instead, Oracle has another program, called the "listener" that brokers connection requests; your program talks to the listener on port 1521 and the listener arranges for your program and the database to connect. The database might actually be on another computer but almost never is, except with RAC clusters or failover configurations. So the listener has to be running for most JDBC programs to work.
SQL*Plus can connect to a database instance via TCP/IP, which requires the listener; however, SQL*Plus can also connect to a database instance that is on the same computer via inter-process communication, which does not require the listener. Stopping the listener process and connecting via SQL*Plus is a common way of putting a database into "maintenance mode", where only the database administrator can make changes to the DB.
The standard Oracle installation will install everything and set up the listener and have it autostart on boot and everything else needed. However, people sometimes disable things they think they don't need, so it's not unheard of for people to turn off the listener becaus they think they don't need it. Or sometimes there's an error and the listener fails to start...

L7580 net printer driver disappearing in Win 7-62 after connecting with Remote Desktop Connection

I have an Officejet Pro L7580 connected via ethernet. I've been using the driver released from Jan 2010, and whenever I connect to my Windows 7 Ultimate 64 computer via Remote Desktop Connection, the printer drivers for both the printer and the fax disappear. I have to constantly run the "add a device" window to add the printers back again.
Why do they disappear like that?

OK after updating the Server and clients I am still having this issue :(
and just today after no sound problems for 6 days the sound dropped out on a couple of RDP sessions, yet the sound on the client itself worked fine when tested (minimise the RDP session).
It took the RDP sessions to be restarted to restore the sound within the session.
I have found similar (old) thread regarding this problem:
https://social.technet.microsoft.com/Forums/windowsserver/en-US/958fd891-6f55-432b-8268-a326ac6b2b2e/sound-in-remote-desktop-session-stops-working
but no one has informed about if as solution was ever found.

What are hidden home and net network drives?

I have 2 icons on my desktop called net and home, both have a size of zero both are partially greyed out. They stay on the desktop regardless of whether or not I'm actually connected to a network. I found them using tinkertool and setting 'show hidden and system files' and going to finder preferences and selecting 'connected servers'. I can't disconnect from them. I was wondering what they are for.

Turn off the display of hidden files/folders and they should disappear from view. They are used by the OS, not the user.

Can I Put My Organizer Catalog On A Net Work Drive An Share It With Two Computers?

PhotoShop Elements 11, Running Under Windows 7 Professional
The second system would be Running Windows 8.1
It would be nice if I could share the Organizer Catalog between the two systems.
If that does not work, I can back the Catalog up on the Network Drive from the primary system (Running Windows 7) and then download it to the second system (Running Windows 8) since production would take place on the Windows 7 system. It would just be nice to always have both systems "in sync".

I guess that is not a surprise. Multiple systems accessing a database at the same time is difficult to manage.
I will choose to make frequent back-up on the network drive and then load those backups on the secondary computer. This restricts the secondary computer from doing any work that needs to be retained but, that is OK.
Thanks for your answer.

Mkinitcpio-nfs-utils hook for net without wireless

Is there a way to make a net hook for diskless clients without including wireless? Make one called net-nowireless or something like that. If my diskless client has a wireless card, I'd have to go into emergency shell to connect the wireless network device to a wireless network if it would even let me do that. Otherwise, I have to blacklist any perceivable wireless module and include it in my mkinitcpio.conf. Some wireless devices can be canned just by not including the firmware. Anyways, my diskless client hangs on the wireless deadlock when initializing network interfaces. It would also probably remove firmware messages and make the initramfs-linux.img smaller. The PXE clients can only boot from the hardwired ethernet clients for now.
Doing a mkinitcpio -L doesn't even list the net hook, but mkinitcpio -H net shows the details.

It does look like the hook tries to connect using all autodetected network devices, regardless of number and type of devices.
While it may be possible to differentiate between wired and wireless devices, that will still give issues if there are multiple wired/wireless devices.
Maybe a configuration file could be added that specifies which devices nfs should use.
If there's no config file present in the initramfs, it should just default to all detected devices as it does now.
Although I haven't tried it this way, it makes sense because that's what it does with the wireless, which just has the unresolvable problem, whereas dual ethernet or more, as long as it satisfies getting an address via dhcp, can probably still boot. Maybe this is the reason why OpenBSD is still anal about using stateful routines through rarpd and bootparamd. I've tried to boot OpenBSD under Arch, using rarp, but I guess it doesn't answer satisfactory to OpenBSD's diskless request. The purpose of stateless is to boot anybody. Various options can be set in pxelinux.cfg based on MAC address, but maybe these aren't known ahead of time to boot a customized initramfs-linux.img.
The real boon was to turn on a dumb-terminal and as soon as it came on, the login prompt was present. This was probably a function of getty.

HP Officejet 4255 driver for Windows 7, 32 bit. Not in pull up list or OS(can't update)

HP Officejet 4255 driver for Windows 7, 32 bit.
Driver is not in pull up list and not in OS(can't update OS basic). Almost all series are listed but 4200 series is missing.
After upgrade to Windows 7, it has become a problem. Some solution should be given.
Can someone help?

Ok, I found in the Net the drive 7uw706ww.zip, which is Version 6.1.4.2, while the updated version is 6.1.10.5 (7UW708WW).
I tried again the GPS, and it wasn't working.
Anyway, before downgrading, I tried to reinstall the new driver, downloading and installing the .exe instead going through System Update.
Result: now GPS is working (same place, same conditions, just 5 minutes later)!
Don't know where the difference is...

X301 and Vodafone and AT&T Wireless WAN (HSPA) Driver for Windows 7 (32-bit, 64-bit)

Ok, I (Lenovo) did it again.
System Update showed me this update: "Vodafone and AT&T Wireless WAN (HSPA) Driver for Windows 7 (32-bit, 64-bit)".
As I'm using Vodafone and I had a AT&T driver, I decided to update.
The result is, that now the GPS doesn't work.
Yes, I'm in a place where the GPS signal is present (my house, with the previous driver I was able to get 6/7 satellites).
What happens? Lenovo TV GPS stays there trying to fix the satellites, but nothing happens. I can't recover the system to a previous state, as I updated Flash player too, and Windows only show me the possibility to roll back this update.
So, apart advicing everyone not to update, I kindky ask:
- where can I found the previous driver? I searched the web without success...
- why does Lenovo deploy driver which can cause problems (I just had one updating the BT driver last week! .msi installer problem, error 1935...)?
Thanks to everyone

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Motherboard crashed, hard drive missing LR and 100 gigs of photo files

able to save drive, put in ext ensclosure and hooked it up tp laptop. am able to open My Pictures folder, only 10 gigs worth of pics visible.
should be 126 gigs. most programs still on drive and accessible: i tunes, all canon photo software, etc. the LR catalog is nowhere to be found.
when this drive was in the desktop there was 25 gigs free space left. viewing the drive hooked up to laptop it also shows 25 gigs free.
wondering if this info is false. if not, where are my missing files and LR ???
i do have my stuff backed up but not sure if all of it backed up, specifically some photo files.
have tried booting from the drive instead of from laptop drive, windows would not allow. desktop was xps, laptop is vista. during that boot i actually saw the xps logo come up a couple of times but then it went to vista.
any help would be appreciated.
a tech friend suggested hooking drive up to his linux os which i am going to do this weekend.

Sounds like you have two problems. 1) Unable to load LR onto the second system (laptop) and 2) the hard drive with original system files has a corrupted file system due to motherboard failure and system crash.
Problem 1: LR license activation allows loading onto two (2) systems. Did you load LR on two systems prior to the crash, which is now preventing you from activating the copy on your laptop? You may need to call Adobe Tech Support to "free-up" the license on your crashed system.
Problem 2: You will need to some data recovery work, due to a corrupted file system on the original HDD. There are numerous data recovery software applications available as freeware or for purchase:

I only have experience with Acronis True Image Home 2010, and definitely would NOT recommend their products due to bugs and poor tech support. Perhaps someone else on the LR forums can suggest a specific data recovery application?
