legato networker agent on gentoo ???

I would like to backup my gentoo server, but the corporate backup solution is legato networker. Does anyone use a networker agent on his gentoo box ?

I am getting ready to set up networker on the servers I admin. I spoke with our Legato admin today, and he said that there were some extra steps to making legato work properly with gentoo. In addition, the company doesn't support gentoo. However, they were willing to help him work out a solution the last time he needed to do this, and he still has the notes. I'll post my experience once I get it done.

I had very little trouble setting up networker for gentoo. I used a rpm package (originally for a redhat 9 machine). Since I don't know how to create ebuilds yet, I just used the rpm2targz to create an archive that I just extracted into the /usr tree. I also wrote a simple init script. From there, all I needed to do was open the appropriate ports on the firewall.

I have heard that the default gentoo /etc/hosts file can cause some problems if left unmodified. You need to make sure that your hostname isn't associated with 127.0.0.1.
// either of the following would cause a problem

UPDATE 06.02.2006

HOWTO:

Networker Client under Gentoo

Ver. Networker-Client 7.1A00-04.i386

1. Download Client here www.webwindow.org/download/networker.tar.gz

2. Save networker.tar.gz on backup mashine on the root /

3. Extract tar -xzf networker.tar.gz

4. Add backup server ip adress:
nano -w /etc/hosts
000.000.000.000 backup
000.000.000.000 backup.domain.name

5. Make link
ln -s /opt/nsr/nsrexecd /usr/bin/nsrexecd

6. Add backup server

nano -w /nsr/res/servers
backup
backup.domain.name

7. Copy lib files in to the lib folder

cp -fr /opt/nsr/lib/* /lib/

8. Start Networker-Client

/etc/init.d/networker start

9. Test your Networker-Client connection

netstat -taupen |grep nsr

tcp 0 0 0.0.0.0:7937 0.0.0.0:* LISTEN 0 458787 13903/nsrexecd
tcp 0 0 0.0.0.0:7938 0.0.0.0:* LISTEN 0 458777 13901/nsrexecd
udp 0 0 0.0.0.0:7938 0.0.0.0:* 0 458776 13901/nsrexecd

10. Add Networker-Client startup on boot

rc-update add networker default

THE END

I tried to install the legato networker as described in zomigo's how-to.

Alltough I had another filename for the client:
lgtoclnt-7.1.3-1.i686.tar.gz

I unpacked the tar mentioned above under / and it moved it's stuff in the following directories:

./usr/
./usr/bin/
./usr/bin/networker

./usr/sbin/nsrsup
./usr/sbin/preclntsave
./usr/sbin/pstclntsave
./usr/sbin/save
./usr/sbin/savefs
./usr/sbin/savepnpc

I added the backupserver in /etc/hosts

I couldn't find /nsr/res/servers

I linked /usr/sbin/nsrexecd to /usr/bin/nsrexecd

I linked /usr/bin/networker into /etc/init.d/networker

If I try to run '/etc/init.d/networker start' I get the following error-message:

NetWorker: Cannot contact nsrexecd service on u011sys0.nzz.ch, Service not available.
Error: Can't open display:

If I start '/usr/sbin/nsrexecd' by hand, I see all the needed ports in netstat. If I then try to start networker again, I get the following error message:

Error: Can't open display:

Does anyone have an idea how to interpret this "Can't open display:"?

Thanks a lot for your kind help!

While evaluating my new servers i stumbled across Gentoo and i'm stunned. The
whole concept of portage and the absence of stupid configuration tools like Yast or
Anaconda pleased me. The choice is not definive yet as i'm waiting for the server
hardware and playing around with different linux flavours on some testboxes. But
the tendency to go Gentoo is STRONG :!:

I have experince in implementing and managing legato networker environments
and for my new servers legato networker will be the backup solution of choice. I
don't really like the idea of just unpacking some files so i'll defininately will learn
how to make a binary package for the client and server part of networker. Did
anybody already test if the libraries contained in lgtodrvr work with kernel 2.6 ?
Well, i'll test that anyway and i hope i don't have to run an old 2.4 kernel

@sc0000b

do:
#export DISPLAY=":0.0"

or simply:
#networker -display :0.0

should help....

I've been using the Legato client on Gentoo for over a year now.

However, I'm currently trying to migrate from our old (RH 7.1) backup server to a new Gentoo based one.
The DLT8000 drives I'm using are detected fine, but I'm completely unable to use our ADIC Scalar 1000 tape jukebox.

jbconfig locks up immediately (strace shows it hanging on open(/dev/nst0,O_RONLY) after probing the /dev/sgX devices in the system)
mt can manipulate /dev/nstX fine, and Networker is capable of reading/writing to the drives without any problems.

Anybody gotten jbconfig and/or Networker to work with a Gentoo server? (This is with an LSI dual-channel HVD SCSI card)
I can edit the /nsr/res/nsrjb.res file to point to the scsidev@X.X.X directly without running jbconfig, but attempting to pass commands to the jukebox does nothing.

Oh, I suppose I might as well add this in here.

Here's a Gentoo version of the networker start script. It works with both the client and server, at least on my version (6.1.4, so its old).

Folks, thanks for the how-to. I tried the Installation with little success. I am able to start backups from the Clientside itself:

ok - i did found the error: Make sure to have the Portmapper started before starting the Networker Client...

I've thrown together an ebuild for legato networker client that uses lgtoclnt-7.0-1.i686.rpm . it's for internal usage, so it got its flaws, overwrites settings on subsequent installs etc.. but it works. I would rather have it install under /opt, but it didn't seem to work when I tested. it contains an init.d script based on a script from another poster in this thread.

good luck
