Need Help

Dear Sir, I have been struggling to get bold letters in informix for CentoS 4.8 and I came across your article on PCL Command Sequences and I felt you could help. I have the following declarations and print command in my informix-4gl but things don't seem to get right. BoldOn CHAR(6), BoldOff CHAR(6) ----LET BoldOn = ASCII 27, ASCII '&040', ASCII '&115', ASCII '&052', ASCII '&066' ----LET BoldOff = ASCII 27, ASCII '&040', ASCII '&115', ASCII '&048', ASCII '&066' LET BoldOn = ASCII 27,"(s4B" LET BoldOff = ASCII 27,"(s0B" PRINT COLUMN 1, BoldOn CLIPPED, " ", "TO WHOM IT MAY CONCERN", BoldOff, COLUMN 54, BoldOn CLIPPED, " ", "Ref: ", BoldOff CLIPPED, r_refno PRINT COLUMN 1, BoldOn CLIPPED, " ", "This is to certify that: ", BoldOff, r_surname, " ", r_firstname and this what I am getting: ^[(s4B TO WHOM IT MAY CONCERN^[(s0B ^[(s4B Ref: ^[(s0B 9844510 ^[(s4B This is to certify that: ^[(s0B NAMONJE CAROL ^[(s4B is a registered student of the National Institute of Public Administration^[(s0B We have HP LaserJet P3005 and P3015 Printers. How can I avoid printing these charaters and instead print Bold letters ? Are there any settings I need to do in Environmental variables or CUPS settings ? Your help will highly be appreciated.

Sendmail TLS verify=fail
by Morten P.D. Stevens 21 Sep '10

21 Sep '10

Hi, I have a small question with sendmail and tls verification. The tls verify fails on our internal/external sendmail servers. For example: STARTTLS=server, relay=mx1.imt-systems.com [89.146.219.60], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 STARTTLS=server, relay=acsinet12.imt-systems.com [89.146.219.42], version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 What's the problem? The sendmail tls certificate should be okay on both servers. Here is the output of the openssl starttls check: Server 1 [root@mx1 ~]# openssl s_client -starttls smtp -connect acsinet12.imt-systems.com:25 New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: FE604F9A1765705F518A416F824DDE0B4316C52F36A3171A1593DC503EB63404 Session-ID-ctx: Master-Key: 57DB71C1E48CA6AC4E5C381B28915AF0A2D66F23D80919E05DFB77345586D6F63AD6C9A7929880E29045CD7D3ADD9556 Key-Arg : None Krb5 Principal: None Start Time: 1285023670 Timeout : 300 (sec) Verify return code: 0 (ok) --- 250 HELP quit 221 2.0.0 acsinet12.imt-systems.com closing connection On the other server: Server 2 [root@acsinet12 ~]# openssl s_client -starttls smtp -connect mx1.imt-systems.com:25 New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: zlib compression Expansion: zlib compression SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: 4FEA16066A719033CEA69C185EDDA504CA8EDB1BB572C21A6BEB303F15F76621 Session-ID-ctx: Master-Key: 615713E2500A52E996F2BB27F3A6A0CF9A471212805120BCC81623656327A9B6184BBB61F6CF28D6E62408397CF2D221 Key-Arg : None Krb5 Principal: None PSK identity: None PSK identity hint: None Compression: 1 (zlib compression) Start Time: 1285024237 Timeout : 300 (sec) Verify return code: 0 (ok) --- 250 HELP quit 221 2.0.0 mx1.imt-systems.com closing connection The verify return code: 0 (ok) seems to be okay on both servers?

Software RAID + LVM + Grub
by Matthew Topper 21 Sep '10

21 Sep '10

I'm playing with software RAID and LVM in some virtual machines and I've run into an issue that I can't find a good answer to in the docs. I have the following RAID setup: md0: sda1 and sdb1, RAID 1. This is /boot md1: sda2 and sdb2, RAID 1. This is a PV for LVM. VolGroup00, this is the volume group and md1 is the only PV in it. LogVol00 is swap LogVol01 is / LogVol02 is /home So, I tested to see what happens if I disable sdb in virtualbox. Machine booted find and I was able to see that part of the raid array was gone. I reattached the disk and rebuilt the array mdam --add /dev/md0 /dev/sdb1 mdam --add /dev/md1 /dev/sdb2 The array rebuilt without issue. But now, if I remove sda, the machine doesn't boot and grub complains. The question I have is how does one reinstall the boot sector at this point? I'm a little confused as far as to what device to install it on and what to specify as the root. This is grub.conf if it helps: default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz title CentOS (2.6.18-194.e15) root (hd0,0) kernel /vmlinuz-2.6.18-194.e15 ro root=/dev/VolGroup00/LogVol01 initrd /initrd-2.6.18-194.e15.img Grub has always been a little confusing for me, so I guess I don't understand. What do the two root entries specify? And again, my main question is how do I reinstall grub to the repaired disk? Sorry for the lengthy post, I'm trying to provide as much information as possible.
