I have a weird one and at this point i'm not sure if its a bug or a feature. i have two NFS mountpoints from two different Netapp filers. on one netapp filer mountpoint, a user who owns the mountpount directory may create a file in the mountpoint and then chown that file to any other...

I set the value of $port outside of a while loop read in a file and pull two variable out of it, sometimes the second variable(port) is set, sometimes not.. but if not, then i want it to have a default value seems to be the only way i can solve this is by explicitly checking for $port on each...

I have a user who needs to change which group files get written out as several times within a script. at first we looked at using setgroups and newgrp but those spawn a new shell and thus break the script. i know at the end of the day we can just do a chgrp as a second operation for whatever...

I'm curious, over the past week i've been playing with xCAT 2.2 to centrally manage our linux/aix servers.. on the aix side of the house it was a breeze, after digging around and finding the right combo of doc's it all came together pretty quick and i've got both software and hardware control...

ok, this isn't a technical question and I really don't want it to turn into a flamewar but i'm curious.. have any of you noticed what seems like a drop in the quality of service from IBM's software support? I've always had the occasional issues.. fighting through level 1 guys... working through...

I need to match numbers 200-220 in a string, this seems pretty simple but i'm having a hard time getting it to match exactly those numbers.. matching 200-219 i can do but matching up to 220 but not 221 im struggling with. sample: #!/usr/bin/perl my $var = $ARGV[0]; if ( $var =~ /2[0-1][0-9]/...

i'd like to pose a question regarding striping at the lvm layer and on the backend. we have ESS SAN storage made up of raid-5 packs carved up and sent out to the LPAR's, I don't have a lot of exposure to the backend but I trust the SAN guys know what they're doing and we don't particularly have...

the scenario is this: we have a source DMX and target DMX doing SRDF/A replication. during a DR event we have a script that reads through a csv file of hosts/VG/hdisk's to do importvg's on all the replicated VG's importing them with a dev known to be in that vg. my question is this, is there...

digging further into making our linux servers conform to the same password policy as the aix boxes i've been reading up a bit on pam_cracklib and have a few questions. first, i understand the whole credits scheme for setting password complexity but why does setting a dcredit to "-1" seemingly...

ok, i've recently started getting more involved with the linux side of the house and am finding that the linux VMM is not as well documented as some other OS's.. or maybe it is and I just haven't found a single solid source of information.. instead, i've found many different articles by many...

ok, this should be pretty simple and im sure several others out there have implemented this. i need to lock accounts that have been unused for 90 days. my first thought was to simply grab the time_last_login out of lsuser for ALL, do a little math and chuser any offenders. but several...

this should be pretty simple.. I want a list of all users unsuccessful_login_count I have a system that is an LDAP client, if I issue an lsuser -ca unsuccessful_login_count against both a local and LDAP authenticated user I can see the permissions. [root@lab04:/etc/security]: lsuser -ca...

I have an AIX 6.1 server that i'm using as a testbed for LDAP authentication. i've configured idsldap client successfully and the world is at peace.. however, per security policies I need AIX to follow certain attributes in the ppolicy overlay on my ldap server. specifically, when an admin...

ok, I must be doing something really stupid here but for the life of me I cannot figure this out and haven't been able to find any mailing lists/forums that pertain to rpm. I'm in the process of attempting to install a new version of curl because after an openssl update the old RPM fails with...

ok, so i've noticed some of my AIX servers have etX devices in my ifconfig -a output but I'm not sure what they are. I go out and search, the AIX FAQ says that the etX devices are for frame types, enX being DIX for TCPIP and etX devices set up for 802.3 framing. all my AIX servers are...

I don't really have a problem but am curious to know why i'd have entitled capacity over 100% -and- idle cycles on a micropartitioned LPAR: server: 9117-MMA AIX xxxxxxxxxx 3 5 00CB1C904C00 05/27/08 System configuration: lcpu=4 ent=1.10 mode=Uncapped 14:51:46 %usr %sys %wio %idle...

ok, so I have system that last week was on a P5 P570 and this week has been migrated to a P6 P570 server. since the tech refresh, we've begun seeing periodic system hangs where for up to 30seconds we lose all response from the system and then it recovers. this appears to be when the system...
