limit established ssh connections with iptables
Hello - I'm trying to limit the number of "ESTABLISHED" ssh connections from a specific ip address with iptables. For example. I'm trying to say ip x.x.x.x can have up to 10 established connections to my sftp-server (openssh). Here is the command I've been using. root@server:/proc>...- hfaix

iostat tps, what's alarming?
I'm looking at days and days worth of I/O stat data trying to determine if I have an I/O bottleneck. Specifically, I've been asked to see if I have a disk hotspot. In analysis I see two hdisks (out of 15) that have tps on occasion between 600 and 800. Is this bad? I've tried using... -
custom shutdown script problem
I've been an AIX admin for about 5 years, however I'm currently writing our Linux standards. I admit, I'm fairly green when it comes to Linux but I've read a lot about runlevels and think I have it figured out..... I'm trying to add a custom script on RHEL5 that runs on reboot. I've written...- hfaix

AIX print queue creates pdf
I was posed with a very unique question and I'm wondering what your thoughts are. Can an AIX print queue be created that takes print requests and instead of sending to a printer, the request is turned into a pdf on the server (in some directory)? Is this too far fetched? -
Downside to scp?
We had a customer stop supporting scp today. I don't understand why. They will only allow us to use sftp. Now we have hours and hours of re-scripting to do. Do you know of a downside to scp (in comparison to sftp)?- hfaix

AIX with NetApp?
Hey - Is anyone doing AIX (5.3) with NetApp? If so, are you mounting NFS filesystems or do you use SAN? We're an ESS SAN shop, but NetApp has some nice, price-competitive, technologies out there and I might have a need for NFS. I'm a little concerned over using NAS and NFS for an Oracle... -
SVN on AIX ?
Has anyone successfully compiled or installed SVN on AIX (5.3)? I'm trying to compile it as per the instructions, however I keep getting a "configure: error: subversion requires zlib" even though I downloaded and extracted the dependency packages (with zlib). Any thoughts? I found a... -
What is bos.adt.prof for?
What is bos.adt.prof for? I assume it's some performance fileset. It's is in all the DST APARS, but several of my system don't have the fileset. -
how do you name your AIX servers?
Do you use standardized names or "random" names (example "bert and earnie" or "bill and ted"? I'm not asking for what names you use...just how you come to a name (standard or random). Just curious.....this is a big discussion around our shop. -
vscsi0 or vscsi1
I know you can set priorities on which virtual client scsi adapter to use, however changing priorities is done at the hdisk level and requires a reboot. Is vscsi0 always the default, even though both have a priority of 1 by default? Thanks again, -
dual vio paths: hcheck_interval disk attribute
Does anybody know if a reboot is required after changing the hcheck_interval attribute of a mpio client hdisk (of a dual vio config)? This allows for automatic path recovery if a vio goes down and comes back up. The APV redbook (sg247940) doesn't say anything about it, but I found this link... -
Clients that are NFS connected to Server
Does anyone know of a way to determine (from an AIX 5.3 NFS Server) if any hosts are NFS mounted to the server. I have searched many threads on here, and this is the closest one I've gotten to a solution. thread52-1139757. netstat -an |grep 2049 works great....assuming a connection has... -
nfs automount
Does anyone use the automounter for NFS connections? Using this the NFS connection disconnects after not being used for a specified amount of time. It seems like the perfect solution for avoiding NFS hangs if the export server is shutdown with an open connection. I have got it working in a... -
sddpcm path problem
I have just completed building a new boot from SAN AIX 5.3 server (from a mksysb of a different server). For whatever the reason, one of my HBA's isn't connecting properly to the disk subsystem (ESS 800). If I remove the devices (rmdev -dl fcs1 -R) and then rerun cfgmgr, I get: Method error... -
Samba on AIX 5.3 joining Active Directory
I have been trying to join an AIX 5.3 server, with samba 3.0.22 to our current active directory domain (win2k3). I have krb5 installed "properly" but I'm still having problems. I can do a kinit USER@REALM I get a ticket sucessfully, however when I do the "net ads join -U USER" command I get... -
Samba on AIX with Microsoft Active Directory
Has anyone successfully tied a samba server (running on AIX) into Msft Active Directory? I've done some reading and I believe I need to install kerberos and an ldap client. However, I'm uncertain about the procedure and AIX filesets needed. Can I use the AIX kerberos filesets on the expansion... -
AIX Fast Connect
Does anyone know the pricing model (and a rough price) for AIX Fast connect 3.2 (for aix 5.3)? Seems like a hassle to get someone (business partners) to give me a price. -
AIX to Windows File Share
Other than SAMBA.... are their any "good" UNIX to Windows File sharing "tools"? I have experience with SAMBA, however I am not completely fond of it. Are their any enterprise packages? $$ or free ie.... I want to map a unix filesystem to windows file system -
file creation date format
Does anybody know why on some of my machines the date of a file created today is : -rw------- 1 root system 126 Mar 6 and on other machines it is: -rw------- 1 root system 108 Mar 06 Both of these are output from AIX 5.3 ML3 machines. Notice how the first one... -
AIX 5.3 from 64 bit to 32 bit
I have been using a standard mksysb to build all AIX 5.3 (64 bit) machines in our environment, but today I found out I need to build a 32 bit machine. Can I build a machine as 64 bit, then switch it to 32 bit? If so, how? Thanks!
